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.

text: Recent experimental advances have inspired the development of theoretical
tools to describe the non-equilibrium dynamics of quantum systems. 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.

text: The power factor of poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)
(PEDOT:PSS) film can be significantly improved by optimizing the oxidation level
of the film in oxidation and reduction processes. 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.

text: Optoelectronic effects differentiating absorption of right and left circularly
polarized photons in thin films of chiral materials are typically prohibitively
small for their direct photocurrent observation. 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.

text: We investigate the local self-sustained process underlying spiral turbulence
in counter-rotating Taylor–Couette flow using a periodic annular domain, shaped
as a parallelogram, two of whose sides are aligned with the cylindrical helix
described by the spiral pattern. 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

text: 'Motivated by properties-controlling potential of the strain, we investigate
strain dependence of structure, electronic, and magnetic properties of Sr2IrO4
using complementary theoretical tools: ab-initio calculations, analytical approaches
(rigid octahedra picture, Slater-Koster integrals), and extended t−J model. 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.'

text: 'In this paper, we explore the stability and dynamical relevance of a wide
variety of steady, time-periodic, quasiperiodic, and chaotic flows arising between
orthogonally stretching parallel plates. 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. '

text: We study the effects of osmotic shocks on lipid vesicles via coarse-grained
molecular dynamics simulations by explicitly considering the solute in the system.
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.

text: Several Ising-type magnetic van der Waals (vdW) materials exhibit stable magnetic
ground states. 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.

text: We report the observation of an anomalous nonlinear optical response of the
prototypical three-dimensional topological insulator bismuth selenide through
the process of high-order harmonic generation. 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.

text: 'Lithium bis(trifluoromethylsulfonyl)imide (LiTFSI) based water-in-salt electrolytes
(WiSEs) has recently emerged as a new promising class of electrolytes, primarily
owing to their wide electrochemical stability windows (~3–4 V), that by far exceed
the thermodynamic stability window of water (1.23 V). 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.'

text: Tracing the motion of macromolecules, viruses, and nanoparticles adsorbed
onto cell membranes is currently the most direct way of probing the complex dynamic
interactions behind vital biological processes, including cell signalling, trafficking,
and viral infection. 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.

text: 'The fundamental and practical importance of particle stabilization has motivated
various characterization methods for studying polymer brushes on particle surfaces.
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.'

text: Confining molecules can fundamentally change their chemical and physical properties.
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.

text: The interaction of strong near-infrared (NIR) laser pulses with wide-bandgap
dielectrics produces high harmonics in the extreme ultraviolet (XUV) wavelength
range. 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.

text: Recent discoveries have shown that, when two layers of van der Waals (vdW)
materials are superimposed with a relative twist angle between them, the electronic
properties of the coupled system can be dramatically altered. 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.

text: We demonstrate a method for manipulating small ensembles of vortices in multiply
connected superconducting structures. 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.

text: Efficient isomerization of photochromic molecules often requires conformational
freedom and is typically not available under solvent-free conditions. 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.

text: Biological membranes typically contain a large number of different components
dispersed in small concentrations in the main membrane phase, including proteins,
sugars, and lipids of varying geometrical properties. 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.

text: The development of strategies to assemble microscopic machines from dissipative
building blocks are essential on the route to novel active materials. 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.

text: 'Cellular membranes exhibit a large variety of shapes, strongly coupled to
their function. 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.'

text: We present an improved fast mixing device based on the rapid mixing of two
solutions inside the NMR probe, as originally proposed by Hore and coworkers (J.
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.

text: We study phase behaviour of lipid-bilayer vesicles functionalised by ligand–receptor
complexes made of synthetic DNA by introducing a modelling framework and a dedicated
experimental platform. 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.

text: We describe colloidal Janus particles with metallic and dielectric faces that
swim vigorously when illuminated by defocused optical tweezers without consuming
any chemical fuel. Rather than wandering randomly, these optically-activated colloidal
swimmers circulate back and forth through the beam of light, tracing out sinuous
rosette patterns. 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.

text: Azobenzenealkanethiols in self-assembled monolayers (SAMs) on Au(111) exhibit
reversible trans–cis photoisomerization when diluted with alkanethiol spacers.
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.

text: The chemical behaviour of molecules can be significantly modified by confinement
to volumes comparable to the dimensions of the molecules. 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.

text: 'Photoswitching in densely packed azobenzene self-assembled monolayers (SAMs)
is strongly affected by steric constraints and excitonic coupling between neighboring
chromophores. 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.'

text: Self-propelled particles can exhibit surprising non-equilibrium behaviors,
and how they interact with obstacles or boundaries remains an important open problem.
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.

text: We present the detailed analysis of a new two-pulse orientation scheme that
achieves macroscopic field-free orientation at the high particle densities required
for attosecond and high-harmonic spectroscopies (Kraus et al 2013 arXiv:1311.3923).
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.

text: In this paper we review recent numerical and theoretical developments of particle
self-assembly on fluid and elastic membranes and compare them to available experimental
realizations. 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.

text: We show how self-assembly of sticky nanoparticles can drive radial collapse
of thin-walled nanotubes. Using numerical simulations, we study the transition
as a function of the geometric and elastic parameters of the nanotube and the
binding strength of the nanoparticles. 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. Our results suggest ways to strengthen the mechanical properties
of nanotubes, but also indicate that the control of nanoparticle self-assembly
on these nanotubes can lead to nanoparticle-laden responsive materials.

text: We perform numerical simulations to study self-assembly of nanoparticles mediated
by an elastic planar surface. We show how the nontrivial elastic response to deformations
of these surfaces leads to anisotropic interactions between the particles resulting
in aggregates having different geometrical features. The morphology of the patterns
can be controlled by the mechanical properties of the surface and the strength
of the particle adhesion. We use simple scaling arguments to understand the formation
of the different structures, and we show how the adhering particles can cause
the underlying elastic substrate to wrinkle if two of its opposite edges are clamped.
Finally, we discuss the implications of our results and suggest how elastic surfaces
could be used in nanofabrication.

text: The accurate experimental determination of dipolar-coupling constants for
one-bond heteronuclear dipolar couplings in solids is a key for the quantification
of the amplitudes of motional processes. 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.

text: We use numerical simulations to show how noninteracting hard particles binding
to a deformable elastic shell may self-assemble into a variety of linear patterns.
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.

text: The reversible molecular template-directed self-assembly of gold nanoparticles
(AuNPs), a process which relies solely on noncovalent bonding interactions, has
been demonstrated by high-resolution transmission electron microscopy (HR-TEM).
By employing a well-known host−guest binding motif, the AuNPs have been systemized
into discrete dimers, trimers, and tetramers. These nanoparticulate twins, triplets,
and quadruplets, which can be disassembled and reassembled either chemically or
electrochemically, can be coalesced into larger, permanent polygonal structures
by thermal treatment using a focused HR-TEM electron beam.

text: The SOFAST-HMQC experiment [P. 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.

text: Supraspheres (SS) composed of hundreds to thousands of metal nanoparticles
(NPs) and crosslinked by dithiol linkers are assembled into larger structures,
which are subsequently converted into nanoporous metals (NMs). Conversion is achieved
by heating which removes organic molecules stabilizing the NPs and allows for
NP fusion. Heating of SS solutions leads to NMs of overall macroscopic dimensions;
localized radiation using collimated electron beam is used to prepare metallized
surface micropatterns. Depending on the composition of supraspherical precursors,
nanoporous materials composed of up to three metals can be obtained. Strategies
for controlling pore size and nanoscale surface roughness of these materials are
discussed.

text: "The interaction of tidal currents with sea-floor topography results in the
radiation of internal gravity waves into the ocean interior. These waves are called
internal tides and their dissipation due to nonlinear wave breaking and concomitant
three-dimensional turbulence could play an important role in the mixing of the
abyssal ocean, and hence in controlling the large-scale ocean circulation.\r\nAs
part of on-going work aimed at providing a theory for the vertical distribution
of wave breaking over sea-floor topography, in this paper we investigate the instability
of internal tides in a very simple linear model that helps us to relate the formation
of unstable regions to simple features in the sea-floor topography. 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. Overall, we find that the distribution of unstable
wave breaking regions can be highly non-uniform even for very simple idealized
topography shapes."

text: Photoswelling of thin films of dichromated gelatin provides a basis for fabrication
of multilevel surface reliefs via sequential UV illumination through different
photomasks. The remarkable feature of this simple, benchtop technique is that
by adjusting irradiation times, film thickness, or its hydration state the heights
of the developed features can be varied from few nanometers to tens of microns.
After UV exposure, the surface structures can be replicated faithfully into either
soft or hard PDMS stamps.

text: We demonstrate the feasibility of recording 1H–15N correlation spectra of
proteins in only one second of acquisition time. The experiment combines recently
proposed SOFAST-HMQC with Hadamard-type 15N frequency encoding. This allows site-resolved
real-time NMR studies of kinetic processes in proteins with an increased time
resolution. The sensitivity of the experiment is sufficient to be applicable to
a wide range of molecular systems available at millimolar concentration on a high

text: A new experimental technique is described that uses reaction−diffusion phenomena
as a means of one-step microfabrication of complex, multilevel surface reliefs.
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.

text: Micropatterning of surfaces with several chemicals at different spatial locations
usually requires multiple stamping and registration steps. 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.
