--- _id: '15018' abstract: - lang: eng text: The epitaxial growth of a strained Ge layer, which is a promising candidate for the channel material of a hole spin qubit, has been demonstrated on 300 mm Si wafers using commercially available Si0.3Ge0.7 strain relaxed buffer (SRB) layers. The assessment of the layer and the interface qualities for a buried strained Ge layer embedded in Si0.3Ge0.7 layers is reported. The XRD reciprocal space mapping confirmed that the reduction of the growth temperature enables the 2-dimensional growth of the Ge layer fully strained with respect to the Si0.3Ge0.7. Nevertheless, dislocations at the top and/or bottom interface of the Ge layer were observed by means of electron channeling contrast imaging, suggesting the importance of the careful dislocation assessment. The interface abruptness does not depend on the selection of the precursor gases, but it is strongly influenced by the growth temperature which affects the coverage of the surface H-passivation. The mobility of 2.7 × 105 cm2/Vs is promising, while the low percolation density of 3 × 1010 /cm2 measured with a Hall-bar device at 7 K illustrates the high quality of the heterostructure thanks to the high Si0.3Ge0.7 SRB quality. acknowledgement: The Ge project received funding from the European Union's Horizon Europe programme under the Grant Agreement 101069515 – IGNITE.

Among them an exact representation of quantum spin systems in terms of classical stochastic processes has been proposed. Here we provide first steps towards the extension of this stochastic approach to bosonic systems by considering the one-dimensional quantum quartic oscillator. We show how to exactly parameterize the time evolution of this prototypical model via the dynamics of a set of classical variables. We interpret these variables as stochastic processes, which allows us to propose a novel way to numerically simulate the time evolution of the system. We benchmark our findings by considering analytically solvable limits and providing alternative derivations of known results. acknowledgement: 'S.

However, precise control over the oxidation and reduction effects in PEDOT:PSS remains a challenge, which greatly sacrifices both S and σ. Here, we propose a two-step post-treatment using a mixture of ethylene glycol (EG) and Arginine (Arg) and sulfuric acid (H2SO4) in sequence to engineer high-performance PEDOT:PSS thermoelectric films. The high-polarity EG dopant removes the excess non-ionized PSS and induces benzenoid-to-quinoid conformational change in the PEDOT:PSS films. In particular, basic amino acid Arg tunes the oxidation level of PEDOT:PSS and prevents the films from over-oxidation during H2SO4 post-treatment, leading to increased S. The following H2SO4 post-treatment further induces highly orientated lamellar stacking microstructures to increase σ, yielding a maximum power factor of 170.6 μW m−1 K−2 at 460 K. Moreover, a novel trigonal-shape thermoelectric device is designed and assembled by the as-prepared PEDOT:PSS films in order to harvest heat via a vertical temperature gradient. An output power density of 33 μW cm−2 is generated at a temperature difference of 40 K, showing the potential application for low-grade wearable electronic devices. acknowledgement: Scientific Research Program Funded by Shaanxi Provincial Education Department (Program No.22JY012), Natural Science Basic Research Program of Shaanxi (Grant No.2022JZ-31), Young Talent fund of University Association for Science and Technology in Shaanxi, China (Grant No.20210411), China Postdoctoral Science Foundation (Grant No. 2021M692621), the Foundation of Shaanxi University of Science & Technology (Grant No. 2017GBJ-03), Open Foundation of Key Laboratory of Auxiliary Chemistry and Technology for Chemical Industry, Ministry of Education, Shaanxi University of Science and Technology (Grant No. KFKT2022-15), and Open Foundation of Shaanxi Collaborative Innovation Center of Industrial Auxiliary Chemistry and Technology, Shaanxi University of Science and Technology (Grant No. KFKT2022-15). article_number: '156101' article_processing_charge: No article_type: original author: - first_name: Li full_name: Zhang, Li last_name: Zhang - first_name: Xingyu full_name: Liu, Xingyu last_name: Liu - first_name: Ting full_name: Wu, Ting last_name: Wu - first_name: Shengduo full_name: Xu, Shengduo id: 12ab8624-4c8a-11ec-9e11-e1ac2438f22f last_name: Xu - first_name: Guoquan full_name: Suo, Guoquan last_name: Suo - first_name: Xiaohui full_name: Ye, Xiaohui last_name: Ye - first_name: Xiaojiang full_name: Hou, Xiaojiang last_name: Hou - first_name: Yanling full_name: Yang, Yanling last_name: Yang - first_name: Qingfeng full_name: Liu, Qingfeng last_name: Liu - first_name: Hongqiang full_name: Wang, Hongqiang last_name: Wang citation: ama: Zhang L, Liu X, Wu T, et al.

Chiral metasurfaces increase the electronic sensitivity to circular polarization, but their out-of-plane architecture entails manufacturing and performance trade-offs. Here, we show that nanoporous thin films of chiral nanoparticles enable high sensitivity to circular polarization due to light-induced polarization-dependent ion accumulation at nanoparticle interfaces. Self-assembled multilayers of gold nanoparticles modified with L-phenylalanine generate a photocurrent under right-handed circularly polarized light as high as 2.41 times higher than under left-handed circularly polarized light. The strong plasmonic coupling between the multiple nanoparticles producing planar chiroplasmonic modes facilitates the ejection of electrons, whose entrapment at the membrane–electrolyte interface is promoted by a thick layer of enantiopure phenylalanine. Demonstrated detection of light ellipticity with equal sensitivity at all incident angles mimics phenomenological aspects of polarization vision in marine animals. The simplicity of self-assembly and sensitivity of polarization detection found in optoionic membranes opens the door to a family of miniaturized fluidic devices for chiral photonics. article_processing_charge: No article_type: original author: - first_name: Jiarong full_name: Cai, Jiarong last_name: Cai - first_name: Wei full_name: Zhang, Wei last_name: Zhang - first_name: Liguang full_name: Xu, Liguang last_name: Xu - first_name: Changlong full_name: Hao, Changlong last_name: Hao - first_name: Wei full_name: Ma, Wei last_name: Ma - first_name: Maozhong full_name: Sun, Maozhong last_name: Sun - first_name: Xiaoling full_name: Wu, Xiaoling last_name: Wu - first_name: Xian full_name: Qin, Xian last_name: Qin - first_name: Felippe Mariano full_name: Colombari, Felippe Mariano last_name: Colombari - first_name: André Farias full_name: de Moura, André Farias last_name: de Moura - first_name: Jiahui full_name: Xu, Jiahui last_name: Xu - first_name: Mariana Cristina full_name: Silva, Mariana Cristina last_name: Silva - first_name: Evaldo Batista full_name: Carneiro-Neto, Evaldo Batista last_name: Carneiro-Neto - first_name: Weverson Rodrigues full_name: Gomes, Weverson Rodrigues last_name: Gomes - first_name: Renaud A.

The primary focus of the study is placed on the emergence of drifting–rotating waves (DRW) that capture, in a relatively small domain, the main features of coherent structures typically observed in developed turbulence. The transitional dynamics of the subcritical region, far below the first instability of the laminar circular Couette flow, is determined by the upper and lower branches of DRW solutions originated at saddle-node bifurcations. The mechanism whereby these solutions self-sustain, and the chaotic dynamics they induce, are conspicuously reminiscent of other subcritical shear flows. Remarkably, the flow properties of DRW persist even as the Reynolds number is increased beyond the linear stability threshold of the base flow. Simulations in a narrow parallelogram domain stretched in the azimuthal direction to revolve around the apparatus a full turn confirm that self-sustained vortices eventually concentrate into a localised pattern. The resulting statistical steady state satisfactorily reproduces qualitatively, and to a certain degree also quantitatively, the topology and properties of spiral turbulence as calculated in a large periodic domain of sufficient aspect ratio that is representative of the real system. acknowledgement: "K.D.’s research was supported by an Australian Research Council Discovery Early Career\r\nResearcher Award (DE170100171).

We find that strain affects both Ir-Ir distance and Ir-O-Ir angle, and the rigid octahedra picture is not relevant. Second, we find fundamentally different behavior for compressive and tensile strain. One remarkable feature is the formation of two subsets of bond- and orbital-dependent carriers, a compass-like model, under compression. This originates from the strain-induced renormalization of the Ir-O-Ir superexchange and O on-site energy. We also show that under compressive (tensile) strain, Fermi surface becomes highly dispersive (relatively flat). Already at a tensile strain of 1.5%, we observe spectral weight redistribution, with the low-energy band acquiring almost purely singlet character. These results can be directly compared with future experiments.' acknowledgement: E.M.P. thanks Eugenio Paris, Thorsten Schmitt, Krzysztof Wohlfeld, and other coauthors for an inspiring previous collaboration23, and is grateful to Gang Cao, Ambrose Seo, and Jungho Kim for insightful discussions.

We first explore the stability of all the steady flow solution families formerly identified by Ayats et al. [“Flows between orthogonally stretching parallel plates,” Phys. Fluids 33, 024103 (2021)], concluding that only the one that originates from the Stokesian approximation is actually stable. When both plates are shrinking at identical or nearly the same deceleration rates, this Stokesian flow exhibits a Hopf bifurcation that leads to stable time-periodic regimes. The resulting time-periodic orbits or flows are tracked for different Reynolds numbers and stretching rates while monitoring their Floquet exponents to identify secondary instabilities. It is found that these time-periodic flows also exhibit Neimark–Sacker bifurcations, generating stable quasiperiodic flows (tori) that may sometimes give rise to chaotic dynamics through a Ruelle–Takens–Newhouse scenario. However, chaotic dynamics is unusually observed, as the quasiperiodic flows generally become phase-locked through a resonance mechanism before a strange attractor may arise, thus restoring the time-periodicity of the flow. In this work, we have identified and tracked four different resonance regions, also known as Arnold tongues or horns. In particular, the 1 : 4 strong resonance region is explored in great detail, where the identified scenarios are in very good agreement with normal form theory.

We find that depending on their nature (hypo- or hypertonic) such shocks can lead to bursting events or engulfing of external material into inner compartments, among other morphology transformations. We characterize the dynamics of these processes and observe a separation of time scales between the osmotic shock absorption and the shape relaxation. Our work consequently provides an insight into the dynamics of compartmentalization in vesicular systems as a result of osmotic shocks, which can be of interest in the context of early proto-cell development and proto-cell compartmentalisation. acknowledgement: We acknowledge support from the Royal Society (C.

Despite these clear experimental demonstrations, a complete theoretical and microscopic understanding of their magnetic anisotropy is still lacking. In particular, the validity limit of identifying their one-dimensional (1-D) Ising nature has remained uninvestigated in a quantitative way. Here we performed the complete mapping of magnetic anisotropy for a prototypical Ising vdW magnet FePS3 for the first time. Combining torque magnetometry measurements with their magnetostatic model analysis and the relativistic density functional total energy calculations, we successfully constructed the three-dimensional (3-D) mappings of the magnetic anisotropy in terms of magnetic torque and energy. The results not only quantitatively confirm that the easy axis is perpendicular to the ab plane, but also reveal the anisotropies within the ab, ac, and bc planes. Our approach can be applied to the detailed quantitative study of magnetism in vdW materials. article_number: '035011' article_processing_charge: No article_type: original author: - first_name: Muhammad full_name: Nauman, Muhammad id: 32c21954-2022-11eb-9d5f-af9f93c24e71 last_name: Nauman orcid: 0000-0002-2111-4846 - first_name: Do Hoon full_name: Kiem, Do Hoon last_name: Kiem - first_name: Sungmin full_name: Lee, Sungmin last_name: Lee - first_name: Suhan full_name: Son, Suhan last_name: Son - first_name: J-G full_name: Park, J-G last_name: Park - first_name: Woun full_name: Kang, Woun last_name: Kang - first_name: Myung Joon full_name: Han, Myung Joon last_name: Han - first_name: Youn Jung full_name: Jo, Youn Jung last_name: Jo citation: ama: Nauman M, Kiem DH, Lee S, et al.

We find that the generation efficiency increases as the laser polarization is changed from linear to elliptical, and it becomes maximum for circular polarization. With the aid of a microscopic theory and a detailed analysis of the measured spectra, we reveal that such anomalous enhancement encodes the characteristic topology of the band structure that originates from the interplay of strong spin–orbit coupling and time-reversal symmetry protection. The implications are in ultrafast probing of topological phase transitions, light-field driven dissipationless electronics, and quantum computation. article_processing_charge: No article_type: original author: - first_name: Denitsa Rangelova full_name: Baykusheva, Denitsa Rangelova id: 71b4d059-2a03-11ee-914d-dfa3beed6530 last_name: Baykusheva - first_name: Alexis full_name: Chacón, Alexis last_name: Chacón - first_name: Jian full_name: Lu, Jian last_name: Lu - first_name: Trevor P. full_name: Bailey, Trevor P. last_name: Bailey - first_name: Jonathan A. full_name: Sobota, Jonathan A. last_name: Sobota - first_name: Hadas full_name: Soifer, Hadas last_name: Soifer - first_name: Patrick S. full_name: Kirchmann, Patrick S. last_name: Kirchmann - first_name: Costel full_name: Rotundu, Costel last_name: Rotundu - first_name: Ctirad full_name: Uher, Ctirad last_name: Uher - first_name: Tony F. full_name: Heinz, Tony F. last_name: Heinz - first_name: David A. full_name: Reis, David A. last_name: Reis - first_name: Shambhu full_name: Ghimire, Shambhu last_name: Ghimire citation: ama: Baykusheva DR, Chacón A, Lu J, et al.

Upon increasing the salt concentration towards superconcentration the onset of the oxygen evolution reaction (OER) shifts more significantly than the hydrogen evolution reaction (HER) does. The OER shift has been explained by the accumulation of hydrophobic anions blocking water access to the electrode surface, hence by double layer theory. Here we demonstrate that the processes during oxidation are much more complex, involving OER, carbon and salt decomposition by OER intermediates, and salt precipitation upon local oversaturation. The positive shift in the onset potential of oxidation currents was elucidated by combining several advanced analysis techniques: rotating ring-disk electrode voltammetry, online electrochemical mass spectrometry, and X-ray photoelectron spectroscopy, using both dilute and superconcentrated electrolytes. The results demonstrate the importance of reactive OER intermediates and surface films for electrolyte and electrode stability and motivate further studies of the nature of the electrode.' article_number: '050550' article_processing_charge: No author: - first_name: Marion full_name: Maffre, Marion last_name: Maffre - first_name: Roza full_name: Bouchal, Roza last_name: Bouchal - first_name: Stefan Alexander full_name: Freunberger, Stefan Alexander id: A8CA28E6-CE23-11E9-AD2D-EC27E6697425 last_name: Freunberger orcid: 0000-0003-2902-5319 - first_name: Niklas full_name: Lindahl, Niklas last_name: Lindahl - first_name: Patrik full_name: Johansson, Patrik last_name: Johansson - first_name: Frédéric full_name: Favier, Frédéric last_name: Favier - first_name: Olivier full_name: Fontaine, Olivier last_name: Fontaine - first_name: Daniel full_name: Bélanger, Daniel last_name: Bélanger citation: ama: Maffre M, Bouchal R, Freunberger SA, et al.

The resulting trajectories are usually consistent with some type of anomalous diffusion, but the molecular origins behind the observed anomalous behaviour are usually not obvious. Here we use coarse-grained molecular dynamics simulations to help identify the physical mechanisms that can give rise to experimentally observed trajectories of nanoscopic objects moving on biological membranes. We find that diffusion on membranes of high fluidities typically results in normal diffusion of the adsorbed nanoparticle, irrespective of the concentration of receptors, receptor clustering, or multivalent interactions between the particle and membrane receptors. Gel-like membranes on the other hand result in anomalous diffusion of the particle, which becomes more pronounced at higher receptor concentrations. This anomalous diffusion is characterised by local particle trapping in the regions of high receptor concentrations and fast hopping between such regions. The normal diffusion is recovered in the limit where the gel membrane is saturated with receptors. We conclude that hindered receptor diffusivity can be a common reason behind the observed anomalous diffusion of viruses, vesicles, and nanoparticles adsorbed on cell and model membranes. Our results enable direct comparison with experiments and offer a new route for interpreting motility experiments on cell membranes. acknowledgement: We thank Jessica McQuade for her input at the start of the project.

In this work, we show how one can perform sensitive measurements of neutral polymer coating on colloidal particles using a commercial zetameter and salt solutions. By systematically varying the Debye length, we study the mobility of the polymer-coated particles in an applied electric field and show that the electrophoretic mobility of polymer-coated particles normalized by the mobility of non-coated particles is entirely controlled by the polymer brush and independent of the native surface charge, here controlled with pH, or the surface–ion interaction. Our result is rationalized with a simple hydrodynamic model, allowing for the estimation of characteristics of the polymer coating: the brush length L, and the Brinkman length ξ, determined by its resistance to flows. We demonstrate that the Debye layer provides a convenient and faithful probe to the characterization of polymer coatings on particles. Because the method simply relies on a conventional zetameter, it is widely accessible and offers a practical tool to rapidly probe neutral polymer brushes, an asset in the development and utilization of polymer-coated colloidal particles.' article_processing_charge: No article_type: original author: - first_name: Mena full_name: Youssef, Mena last_name: Youssef - first_name: Alexandre full_name: Morin, Alexandre last_name: Morin - first_name: Antoine full_name: Aubret, Antoine last_name: Aubret - first_name: Stefano full_name: Sacanna, Stefano last_name: Sacanna - first_name: Jérémie A full_name: Palacci, Jérémie A id: 8fb92548-2b22-11eb-b7c1-a3f0d08d7c7d last_name: Palacci orcid: 0000-0002-7253-9465 citation: ama: Youssef M, Morin A, Aubret A, Sacanna S, Palacci JA.

Confinement effects are considered instrumental at various stages of the origins of life, and life continues to rely on layers of compartmentalization to maintain an out-of-equilibrium state and efficiently synthesize complex biomolecules under mild conditions. As interest in synthetic confined systems grows, we are realizing that the principles governing reactivity under confinement are the same in abiological systems as they are in nature. In this Review, we categorize the ways in which nanoconfinement effects impact chemical reactivity in synthetic systems. Under nanoconfinement, chemical properties can be modulated to increase reaction rates, enhance selectivity and stabilize reactive species. Confinement effects also lead to changes in physical properties. The fluorescence of light emitters, the colours of dyes and electronic communication between electroactive species can all be tuned under confinement. Within each of these categories, we elucidate design principles and strategies that are widely applicable across a range of confined systems, specifically highlighting examples of different nanocompartments that influence reactivity in similar ways. article_processing_charge: No article_type: original author: - first_name: Angela B. full_name: Grommet, Angela B. last_name: Grommet - first_name: Moran full_name: Feller, Moran last_name: Feller - first_name: Rafal full_name: Klajn, Rafal id: 8e84690e-1e48-11ed-a02b-a1e6fb8bb53b last_name: Klajn citation: ama: Grommet AB, Feller M, Klajn R.

These observations have opened up the possibility of attosecond metrology in solids, which would benefit from a precise measurement of the emission times of individual harmonics with respect to the NIR laser field. Here we show that, when high-harmonics are detected from the input surface of a magnesium oxide crystal, a bichromatic probing of the XUV emission shows a clear synchronization largely consistent with a semiclassical model of electron–hole recollisions in bulk solids. On the other hand, the bichromatic spectrogram of harmonics originating from the exit surface of the 200 μm-thick crystal is strongly modified, indicating the influence of laser field distortions during propagation. Our tracking of sub-cycle electron and hole re-collisions at XUV energies is relevant to the development of solid-state sources of attosecond pulses. article_number: '144003' article_processing_charge: No article_type: original author: - first_name: Giulio full_name: Vampa, Giulio last_name: Vampa - first_name: Jian full_name: Lu, Jian last_name: Lu - first_name: Yong Sing full_name: You, Yong Sing last_name: You - first_name: Denitsa Rangelova full_name: Baykusheva, Denitsa Rangelova id: 71b4d059-2a03-11ee-914d-dfa3beed6530 last_name: Baykusheva - first_name: Mengxi full_name: Wu, Mengxi last_name: Wu - first_name: Hanzhe full_name: Liu, Hanzhe last_name: Liu - first_name: Kenneth J full_name: Schafer, Kenneth J last_name: Schafer - first_name: Mette B full_name: Gaarde, Mette B last_name: Gaarde - first_name: David A full_name: Reis, David A last_name: Reis - first_name: Shambhu full_name: Ghimire, Shambhu last_name: Ghimire citation: ama: 'Vampa G, Lu J, You YS, et al.

Here, we demonstrate that a similar concept can be extended to the optics realm, particularly to propagating phonon polaritons–hybrid light-matter interactions. To do this, we fabricate stacks composed of two twisted slabs of a vdW crystal (α-MoO3) supporting anisotropic phonon polaritons (PhPs), and image the propagation of the latter when launched by localized sources. Our images reveal that, under a critical angle, the PhPs isofrequency curve undergoes a topological transition, in which the propagation of PhPs is strongly guided (canalization regime) along predetermined directions without geometric spreading. These results demonstrate a new degree of freedom (twist angle) for controlling the propagation of polaritons at the nanoscale with potential for nanoimaging, (bio)-sensing, or heat management. acknowledgement: "J.T.-G. and G.Á.-P. acknowledge support through the Severo Ochoa Program from the\r\nGovernment of the Principality of Asturias (nos.

A micron-size magnetic particle attached to the tip of a silicon cantilever is used to locally apply magnetic flux through the superconducting structure. By scanning the tip over the surface of the device and by utilizing the dynamical coupling between the vortices and the cantilever, a high-resolution spatial map of the different vortex configurations is obtained. Moving the tip to a particular location in the map stabilizes a distinct multivortex configuration. Thus, the scanning of the tip over a particular trajectory in space permits nontrivial operations to be performed, such as braiding of individual vortices within a larger vortex ensemble—a key capability required by many proposals for topological quantum computing. acknowledgement: We are grateful to Nadya Mason, Taylor Hughes, and Alexey Bezryadin for useful discussions.

Here, we report a general methodology allowing for reversible switching of such molecules on the surfaces of solid materials. Our method is based on dispersing photochromic compounds within polysilsesquioxane nanowire networks (PNNs), which can be fabricated as transparent, highly porous, micrometer-thick layers on various substrates. We found that azobenzene switching within the PNNs proceeded unusually fast compared with the same molecules in liquid solvents. Efficient isomerization of another photochromic system, spiropyran, from a colorless to a colored form was used to create reversible images in PNN-coated glass. The coloration reaction could be induced with sunlight and is of interest for developing “smart” windows. article_processing_charge: No article_type: original author: - first_name: Zonglin full_name: Chu, Zonglin last_name: Chu - first_name: Rafal full_name: Klajn, Rafal id: 8e84690e-1e48-11ed-a02b-a1e6fb8bb53b last_name: Klajn citation: ama: Chu Z, Klajn R.

Most of these components do not bind the cargo. Here, we show that such “inert” components can be crucial for the precise control of cross-membrane trafficking. Using a statistical mechanics model and molecular dynamics simulations, we demonstrate that the presence of inert membrane components of small isotropic curvatures dramatically influences cargo endocytosis, even if the total spontaneous curvature of such a membrane remains unchanged. Curved lipids, such as cholesterol, as well as asymmetrically included proteins and tethered sugars can, therefore, actively participate in the control of the membrane trafficking of nanoscopic cargo. We find that even a low-level expression of curved inert membrane components can determine the membrane selectivity toward the cargo size and can be used to selectively target membranes of certain compositions. Our results suggest a robust and general method of controlling cargo trafficking by adjusting the membrane composition without needing to alter the concentration of receptors or the average membrane curvature. This study indicates that cells can prepare for any trafficking event by incorporating curved inert components in either of the membrane leaflets. acknowledgement: We acknowledge discussions with Giuseppe Battaglia as well as support from the Herchel Smith scholarship (T.C.), the CAS PIFI fellowship (T.C.), the UCL Institute for the Physics of Living Systems (T.C. and A.Š.), the Austrian Academy of Sciences through a DOC fellowship (P.W.), the European Union Horizon 2020 programme under ETN grant no. 674979-NANOTRANS and FET grant no. 766972-NANOPHLOW (J.D. and D.F.), the Engineering and Physical Sciences Research Council (D.F. and A.Š.), the Academy of Medical Sciences and Wellcome Trust (A.Š.), and the Royal Society (A.Š.).

We recently demonstrated the hierarchical self-assembly of phoretic microswimmers into self-spinning microgears and their synchronization by diffusiophoretic interactions [Aubret et al., Nat. Phys., 2018]. In this paper, we adopt a pedagogical approach and expose our strategy to control self-assembly and build machines using phoretic phenomena. We notably introduce Highly Inclined Laminated Optical sheets microscopy (HILO) to image and characterize anisotropic and dynamic diffusiophoretic interactions, which cannot be performed by conventional fluorescence microscopy. The dynamics of a (haematite) photocatalytic material immersed in (hydrogen peroxide) fuel under various illumination patterns is first described and quantitatively rationalized by a model of diffusiophoresis, the migration of a colloidal particle in a concentration gradient. It is further exploited to design phototactic microswimmers that direct towards the high intensity of light, as a result of the reorientation of the haematite in a light gradient. We finally show the assembly of self-spinning microgears from colloidal microswimmers and carefully characterize the interactions using HILO techniques. The results are compared with analytical and numerical predictions and agree quantitatively, stressing the important role played by concentration gradients induced by chemical activity to control and design interactions. Because the approach described hereby is generic, this works paves the way for the rational design of machines by controlling phoretic phenomena. article_processing_charge: No article_type: original author: - first_name: Antoine full_name: Aubret, Antoine last_name: Aubret - first_name: Jérémie A full_name: Palacci, Jérémie A id: 8fb92548-2b22-11eb-b7c1-a3f0d08d7c7d last_name: Palacci orcid: 0000-0002-7253-9465 citation: ama: Aubret A, Palacci JA.

Many biological processes involve dynamic reshaping of membranes, usually mediated by proteins. This interaction works both ways: while proteins influence the membrane shape, the membrane shape affects the interactions between the proteins. To study these membrane-mediated interactions on closed and anisotropically curved membranes, we use colloids adhered to ellipsoidal membrane vesicles as a model system. We find that two particles on a closed system always attract each other, and tend to align with the direction of largest curvature. Multiple particles form arcs, or, at large enough numbers, a complete ring surrounding the vesicle in its equatorial plane. The resulting vesicle shape resembles a snowman. Our results indicate that these physical interactions on membranes with anisotropic shapes can be exploited by cells to drive macromolecules to preferred regions of cellular or intracellular membranes, and utilized to initiate dynamic processes such as cell division. The same principle could be used to find the midplane of an artificial vesicle, as a first step towards dividing it into two equal parts.' acknowledgement: This work was supported by the Netherlands Organisation for Scientific Research (NWO/OCW), as part of the Frontiers of Nanoscience program. article_processing_charge: No article_type: original author: - first_name: Afshin full_name: Vahid, Afshin last_name: Vahid - first_name: Anđela full_name: Šarić, Anđela id: bf63d406-f056-11eb-b41d-f263a6566d8b last_name: Šarić orcid: 0000-0002-7854-2139 - first_name: Timon full_name: Idema, Timon last_name: Idema citation: ama: Vahid A, Šarić A, Idema T.

Am. Chem. Soc. 125 (2003) 12484–12492). Such a device is important for off-equilibrium studies of molecular kinetics by multidimensional real-time NMR spectrsocopy. The novelty of this device is that it allows removing the injector from the NMR detection volume after mixing, and thus provides good magnetic field homogeneity independently of the initial sample volume placed in the NMR probe. The apparatus is simple to build, inexpensive, and can be used without any hardware modification on any type of liquid-state NMR spectrometer. We demonstrate the performance of our fast mixing device in terms of improved magnetic field homogeneity, and show an application to the study of protein folding and the structural characterization of transiently populated folding intermediates. article_processing_charge: No article_type: original author: - first_name: Rémi full_name: Franco, Rémi last_name: Franco - first_name: Adrien full_name: Favier, Adrien last_name: Favier - first_name: Paul full_name: Schanda, Paul id: 7B541462-FAF6-11E9-A490-E8DFE5697425 last_name: Schanda orcid: 0000-0002-9350-7606 - first_name: Bernhard full_name: Brutscher, Bernhard last_name: Brutscher citation: ama: Franco R, Favier A, Schanda P, Brutscher B.

In particular, we perform Monte Carlo simulations that combine a coarse grained description of the lipid bilayer with state of art analytical models for multivalent ligand–receptor interactions. Using density of state calculations, we derive the partition function in pairs of vesicles and compute the number of ligand–receptor bonds as a function of temperature. Numerical results are compared to microscopy and fluorimetry experiments on large unilamellar vesicles decorated by DNA linkers carrying complementary overhangs. We find that vesicle aggregation is suppressed when the total number of linkers falls below a threshold value. Within the model proposed here, this is due to the higher configurational costs required to form inter-vesicle bridges as compared to intra-vesicle loops, which are in turn related to membrane deformability. Our findings and our numerical/experimental methodologies are applicable to the rational design of liposomes used as functional materials and drug delivery applications, as well as to study inter-membrane interactions in living systems, such as cell adhesion. article_processing_charge: No article_type: original author: - first_name: Stephan Jan full_name: Bachmann, Stephan Jan last_name: Bachmann - first_name: Jurij full_name: Kotar, Jurij last_name: Kotar - first_name: Lucia full_name: Parolini, Lucia last_name: Parolini - first_name: Anđela full_name: Šarić, Anđela id: bf63d406-f056-11eb-b41d-f263a6566d8b last_name: Šarić orcid: 0000-0002-7854-2139 - first_name: Pietro full_name: Cicuta, Pietro last_name: Cicuta - first_name: Lorenzo full_name: Di Michele, Lorenzo last_name: Di Michele - first_name: Bortolo Matteo full_name: Mognetti, Bortolo Matteo last_name: Mognetti citation: ama: Bachmann SJ, Kotar J, Parolini L, et al.

We propose a model for this mode of light-activated transport that accounts for the observed behavior through a combination of self-thermophoresis and optically-induced torque. In the deterministic limit, this model yields trajectories that resemble rosette curves known as hypotrochoids. article_processing_charge: No article_type: original author: - first_name: Henrique full_name: Moyses, Henrique last_name: Moyses - first_name: Jérémie A full_name: Palacci, Jérémie A id: 8fb92548-2b22-11eb-b7c1-a3f0d08d7c7d last_name: Palacci orcid: 0000-0002-7253-9465 - first_name: Stefano full_name: Sacanna, Stefano last_name: Sacanna - first_name: David G. full_name: Grier, David G. last_name: Grier citation: ama: Moyses H, Palacci JA, Sacanna S, Grier DG.

Using these mixed SAMs, we show switching of the linear optical and second-harmonic response. The effective switching of these surface optical properties relies on a reasonably large cross section and a high photoisomerization yield as well as a long lifetime of the metastable cis isomer. We quantified the switching process by X-ray absorption spectroscopy. The cross sections for the trans–cis and cis–trans photoisomerization with 365 and 455 nm light, respectively, are 1 order of magnitude smaller than in solution. In vacuum, the 365 nm photostationary state comprises 50–74% of the molecules in the cis form, limited by their rapid thermal isomerization back to the trans state. In contrast, the 455 nm photostationary state contains nearly 100% trans-azobenzene. We determined time constants for the thermal cis–trans isomerization of only a few minutes in vacuum and in a dry nitrogen atmosphere but of more than 1 day in ambient air. Our results suggest that adventitious water adsorbed on the surface of the SAM stabilizes the polar cis configuration of azobenzene under ambient conditions. The back reaction rate constants differing by 2 orders of magnitude underline the huge influence of the environment and, accordingly, its importance when comparing various experiments. article_processing_charge: No article_type: original author: - first_name: Thomas full_name: Moldt, Thomas last_name: Moldt - first_name: Daniel full_name: Przyrembel, Daniel last_name: Przyrembel - first_name: Michael full_name: Schulze, Michael last_name: Schulze - first_name: Wibke full_name: Bronsch, Wibke last_name: Bronsch - first_name: Larissa full_name: Boie, Larissa last_name: Boie - first_name: Daniel full_name: Brete, Daniel last_name: Brete - first_name: Cornelius full_name: Gahl, Cornelius last_name: Gahl - first_name: Rafal full_name: Klajn, Rafal id: 8e84690e-1e48-11ed-a02b-a1e6fb8bb53b last_name: Klajn - first_name: Petra full_name: Tegeder, Petra last_name: Tegeder - first_name: Martin full_name: Weinelt, Martin last_name: Weinelt citation: ama: Moldt T, Przyrembel D, Schulze M, et al.

Although such confined spaces can be found in various nanostructured materials, such as zeolites, nanoporous organic frameworks and colloidal nanocrystal assemblies, the slow diffusion of molecules in and out of these materials has greatly hampered studying the effect of confinement on their physicochemical properties. Here, we show that this diffusion limitation can be overcome by reversibly creating and destroying confined environments by means of ultraviolet and visible light irradiation. We use colloidal nanocrystals functionalized with light-responsive ligands that readily self-assemble and trap various molecules from the surrounding bulk solution. Once trapped, these molecules can undergo chemical reactions with increased rates and with stereoselectivities significantly different from those in bulk solution. Illumination with visible light disassembles these nanoflasks, releasing the product in solution and thereby establishes a catalytic cycle. These dynamic nanoflasks can be useful for studying chemical reactivities in confined environments and for synthesizing molecules that are otherwise hard to achieve in bulk solution. article_processing_charge: No article_type: original author: - first_name: Hui full_name: Zhao, Hui last_name: Zhao - first_name: Soumyo full_name: Sen, Soumyo last_name: Sen - first_name: T. full_name: Udayabhaskararao, T. last_name: Udayabhaskararao - first_name: Michał full_name: Sawczyk, Michał last_name: Sawczyk - first_name: Kristina full_name: Kučanda, Kristina last_name: Kučanda - first_name: Debasish full_name: Manna, Debasish last_name: Manna - first_name: Pintu K. full_name: Kundu, Pintu K. last_name: Kundu - first_name: Ji-Woong full_name: Lee, Ji-Woong last_name: Lee - first_name: Petr full_name: Král, Petr last_name: Král - first_name: Rafal full_name: Klajn, Rafal id: 8e84690e-1e48-11ed-a02b-a1e6fb8bb53b last_name: Klajn citation: ama: Zhao H, Sen S, Udayabhaskararao T, et al.

Therefore, control of the chromophore density is essential for enhancing and manipulating the photoisomerization yield. We systematically compare two methods to achieve this goal: First, we assemble monocomponent azobenzene–alkanethiolate SAMs on gold nanoparticles of varying size. Second, we form mixed SAMs of azobenzene–alkanethiolates and “dummy” alkanethiolates on planar substrates. Both methods lead to a gradual decrease of the chromophore density and enable efficient photoswitching with low-power light sources. X-ray spectroscopy reveals that coadsorption from solution yields mixtures with tunable composition. The orientation of the chromophores with respect to the surface normal changes from a tilted to an upright position with increasing azobenzene density. For both systems, optical spectroscopy reveals a pronounced excitonic shift that increases with the chromophore density. In spite of exciting the optical transition of the monomer, the main spectral change in mixed SAMs occurs in the excitonic band. In addition, the photoisomerization yield decreases only slightly by increasing the azobenzene–alkanethiolate density, and we observed photoswitching even with minor dilutions. Unlike in solution, azobenzene in the planar SAM can be switched back almost completely by optical excitation from the cis to the original trans state within a short time scale. These observations indicate cooperativity in the photoswitching process of mixed SAMs.' article_processing_charge: No article_type: original author: - first_name: Thomas full_name: Moldt, Thomas last_name: Moldt - first_name: Daniel full_name: Brete, Daniel last_name: Brete - first_name: Daniel full_name: Przyrembel, Daniel last_name: Przyrembel - first_name: Sanjib full_name: Das, Sanjib last_name: Das - first_name: Joel R. full_name: Goldman, Joel R. last_name: Goldman - first_name: Pintu K. full_name: Kundu, Pintu K. last_name: Kundu - first_name: Cornelius full_name: Gahl, Cornelius last_name: Gahl - first_name: Rafal full_name: Klajn, Rafal id: 8e84690e-1e48-11ed-a02b-a1e6fb8bb53b last_name: Klajn - first_name: Martin full_name: Weinelt, Martin last_name: Weinelt citation: ama: Moldt T, Brete D, Przyrembel D, et al.

Here we show that chemically propelled micro-rods can be captured, with little change in their speed, into close orbits around solid spheres resting on or near a horizontal plane. We show that this interaction between sphere and particle is short-range, occurring even for spheres smaller than the particle length, and for a variety of sphere materials. We consider a simple model, based on lubrication theory, of a force- and torque-free swimmer driven by a surface slip (the phoretic propulsion mechanism) and moving near a solid surface. The model demonstrates capture, or movement towards the surface, and yields speeds independent of distance. This study reveals the crucial aspects of activity–driven interactions of self-propelled particles with passive objects, and brings into question the use of colloidal tracers as probes of active matter. article_number: '1784' article_processing_charge: No article_type: original author: - first_name: Daisuke full_name: Takagi, Daisuke last_name: Takagi - first_name: Jérémie A full_name: Palacci, Jérémie A id: 8fb92548-2b22-11eb-b7c1-a3f0d08d7c7d last_name: Palacci orcid: 0000-0002-7253-9465 - first_name: Adam B. full_name: Braunschweig, Adam B. last_name: Braunschweig - first_name: Michael J. full_name: Shelley, Michael J. last_name: Shelley - first_name: Jun full_name: Zhang, Jun last_name: Zhang citation: ama: Takagi D, Palacci JA, Braunschweig AB, Shelley MJ, Zhang J.

Carbon monoxide molecules are oriented by combining one-colour and delayed two-colour non-resonant femtosecond laser pulses. High-harmonic generation is used to probe the oriented wave-packet dynamics and reveals that a very high degree of orientation (Nup/Ntotal = 0.73–0.82) is achieved. We further extend this approach to orienting carbonyl sulphide molecules. We show that the present two-pulse scheme selectively enhances orientation created by the hyperpolarizability interaction whereas the ionization-depletion mechanism plays no role. We further control and optimize orientation through the delay between the one- and two-colour pump pulses. Finally, we demonstrate a complementary encoding of electronic-structure features, such as shape resonances, in the even- and odd-harmonic spectrum. The achieved progress makes two-pulse field-free orientation an attractive tool for a broad class of time-resolved measurements. article_number: '124030' article_processing_charge: No article_type: original author: - first_name: P M full_name: Kraus, P M last_name: Kraus - first_name: Denitsa Rangelova full_name: Baykusheva, Denitsa Rangelova id: 71b4d059-2a03-11ee-914d-dfa3beed6530 last_name: Baykusheva - first_name: H J full_name: Wörner, H J last_name: Wörner citation: ama: 'Kraus PM, Baykusheva DR, Wörner HJ.

We discuss the problem and its applications in biology and materials science, and give an overview of numerical models and strategies to study these systems across all length-scales. As this is a very broad field, this review focuses exclusively on surface-driven aggregation of nanoparticles that are at least one order of magnitude larger than the surface thickness and are adsorbed onto it. In this regime, all chemical details of the surface can be ignored in favor of a coarse-grained representation, and the collective behavior of many particles can be monitored and analyzed. We review the existing literature on how the mechanical properties and the geometry of the surface affect the structure of the particle aggregates and how these can drive shape deformation on the surface. acknowledgement: This work was supported by the National Science Foundation under Career Grant No. DMR 0846426.

We find that it is possible to derive a simple scaling law relating all these parameters, and estimate bounds for the onset conditions leading to the collapse of the nanotube. We also study the reverse process – the nanoparticle release from the folded state – and find that the stability of the collapsed state can be greatly improved by increasing the bending rigidity of the nanotubes.

Averaging of the dipolar coupling reports on motions on time scales up to the inverse of the coupling constant, in our case tens of microseconds. Combining dipolar-coupling derived order parameters that characterize the amplitudes of the motion with relaxation data leads to a more precise characterization of the dynamical parameters and helps to disentangle the amplitudes and the time scales of the motional processes, which impact relaxation rates in a highly correlated way. Here. we describe and characterize an improved experimental protocol – based on REDOR – to measure these couplings in perdeuterated proteins with a reduced sensitivity to experimental missettings. Because such effects are presently the dominant source of systematic errors in experimental dipolar-coupling measurements, these compensated experiments should help to significantly improve the precision of such data. A detailed comparison with other commonly used pulse sequences (T-MREV, phase-inverted CP,R18 5/2, and R18 7/1) is provided. article_processing_charge: No article_type: original author: - first_name: Paul full_name: Schanda, Paul id: 7B541462-FAF6-11E9-A490-E8DFE5697425 last_name: Schanda orcid: 0000-0002-9350-7606 - first_name: Beat H. full_name: Meier, Beat H. last_name: Meier - first_name: Matthias full_name: Ernst, Matthias last_name: Ernst citation: ama: Schanda P, Meier BH, Ernst M.

This is a result of the nontrivial elastic response to deformations of shells. The morphology of the patterns can be controlled by the mechanical properties of the surface, and can be fine-tuned by varying the binding energy of the particles. We also repeat our calculations for a fully flexible chain and find that the chain conformations follow patterns similar to those formed by the nanoparticles under analogous conditions. We propose a simple way of understanding and sorting the different structures and relate it to the underlying shape transition of the shell. Finally, we discuss the implications of our results. acknowledgement: This work was supported by the National Science Foundation under Career Grant No. DMR-0846426. We thank Josep C.

Schanda, B. Brutscher, Very fast two-dimensional NMR spectroscopy for real-time investigation of dynamic events in proteins on the time scale of seconds, J. Am. Chem. Soc. 127 (2005) 8014–8015] allows recording two-dimensional correlation spectra of macromolecules such as proteins in only a few seconds acquisition time. To achieve the highest possible sensitivity, SOFAST-HMQC experiments are preferably performed on high-field NMR spectrometers equipped with cryogenically cooled probes. The duty cycle of over 80% in fast-pulsing SOFAST-HMQC experiments, however, may cause problems when using a cryogenic probe. Here we introduce SE-IPAP-SOFAST-HMQC, a new pulse sequence that provides comparable sensitivity to standard SOFAST-HMQC, while avoiding heteronuclear decoupling during 1H detection, and thus significantly reducing the radiofrequency load of the probe during the experiment. The experiment is also attractive for fast and sensitive measurement of heteronuclear one-bond spin coupling constants. article_processing_charge: No article_type: letter_note author: - first_name: Thomas full_name: Kern, Thomas last_name: Kern - first_name: Paul full_name: Schanda, Paul id: 7B541462-FAF6-11E9-A490-E8DFE5697425 last_name: Schanda orcid: 0000-0002-9350-7606 - first_name: Bernhard full_name: Brutscher, Bernhard last_name: Brutscher citation: ama: Kern T, Schanda P, Brutscher B.

For two-dimensional tides over one-dimensional topography we find that the formation of overturning instabilities is closely linked to the singularities in the topography shape and that it is possible to have stable waves at the sea floor and unstable waves in the ocean interior above.\r\nFor three-dimensional tides over two-dimensional topography there is in addition an effect of geometric focusing of wave energy into localized regions of high wave amplitude, and we investigate this focusing effect in simple examples.

Thin films of dry gelatin doped with potassium hexacyanoferrate are chemically micropatterned with a solution of silver nitrate delivered from an agarose stamp. Precipitation reaction between the two salts causes the surface to deform. The mechanism of surface deformation is shown to involve a sequence of reactions, diffusion, and gel swelling/contraction. This mechanism is established experimentally and provides a basis of a theoretical lattice-gas model that allows prediction surface topographies emerging from arbitrary geometries of the stamped features. The usefulness of the technique is demonstrated by using it to rapidly prepare two types of mold for passive microfluidic mixers. article_processing_charge: No article_type: original author: - first_name: Christopher J. full_name: Campbell, Christopher J. last_name: Campbell - first_name: Rafal full_name: Klajn, Rafal id: 8e84690e-1e48-11ed-a02b-a1e6fb8bb53b last_name: Klajn - first_name: Marcin full_name: Fialkowski, Marcin last_name: Fialkowski - first_name: Bartosz A. full_name: Grzybowski, Bartosz A. last_name: Grzybowski citation: ama: Campbell CJ, Klajn R, Fialkowski M, Grzybowski BA.

Here, we describe an experimental method based on reaction–diffusion phenomena that allows for simultaneous micropatterning of a substrate with several coloured chemicals. In this method, called wet stamping (WETS), aqueous solutions of two or more inorganic salts are delivered onto a film of dry, ionically doped gelatin from an agarose stamp patterned in bas relief. Once in conformal contact, these salts diffuse into the gelatin, where they react to give deeply coloured precipitates. Separation of colours in the plane of the surface is the consequence of the differences in the diffusion coefficients, the solubility products, and the amounts of different salts delivered from the stamp, and is faithfully reproduced by a theoretical model based on a system of reaction–diffusion partial differential equations. The multicolour micropatterns are useful as non-binary optical elements, and could potentially form the basis of new applications in microseparations and in controlled delivery. article_processing_charge: No article_type: original author: - first_name: Rafal full_name: Klajn, Rafal id: 8e84690e-1e48-11ed-a02b-a1e6fb8bb53b last_name: Klajn - first_name: Marcin full_name: Fialkowski, Marcin last_name: Fialkowski - first_name: Igor T. full_name: Bensemann, Igor T. last_name: Bensemann - first_name: Agnieszka full_name: Bitner, Agnieszka last_name: Bitner - first_name: C.
