--- _id: '13346' abstract: - lang: eng text: The self-assembly of nanoparticles driven by small molecules or ions may produce colloidal superlattices with features and properties reminiscent of those of metals or semiconductors. However, to what extent the properties of such supramolecular crystals actually resemble those of atomic materials often remains unclear. Here, we present coarse-grained molecular simulations explicitly demonstrating how a behavior evocative of that of semiconductors may emerge in a colloidal superlattice. As a case study, we focus on gold nanoparticles bearing positively charged groups that self-assemble into FCC crystals via mediation by citrate counterions. In silico ohmic experiments show how the dynamically diverse behavior of the ions in different superlattice domains allows the opening of conductive ionic gates above certain levels of applied electric fields. The observed binary conductive/nonconductive behavior is reminiscent of that of conventional semiconductors, while, at a supramolecular level, crossing the “band gap” requires a sufficient electrostatic stimulus to break the intermolecular interactions and make ions diffuse throughout the superlattice’s cavities. article_processing_charge: No article_type: original author: - first_name: Chiara full_name: Lionello, Chiara last_name: Lionello - first_name: Claudio full_name: Perego, Claudio last_name: Perego - first_name: Andrea full_name: Gardin, Andrea last_name: Gardin - first_name: Rafal full_name: Klajn, Rafal id: 8e84690e-1e48-11ed-a02b-a1e6fb8bb53b last_name: Klajn - first_name: Giovanni M. full_name: Pavan, Giovanni M. last_name: Pavan citation: ama: Lionello C, Perego C, Gardin A, Klajn R, Pavan GM.

Here, we describe the concept of photocleavable anionic glue (PAG): small trianions capable of mediating interactions between (and inducing the aggregation of) cationic NPs by means of electrostatic interactions. Exposure to light converts PAGs into dianionic products incapable of maintaining the NPs in an assembled state, resulting in light-triggered disassembly of NP aggregates. To demonstrate the proof-of-concept, we work with an organic PAG incorporating the UV-cleavable o-nitrobenzyl moiety and an inorganic PAG, the photosensitive trioxalatocobaltate(III) complex, which absorbs light across the entire visible spectrum. Both PAGs were used to prepare either amorphous NP assemblies or regular superlattices with a long-range NP order. These NP aggregates disassembled rapidly upon light exposure for a specific time, which could be tuned by the incident light wavelength or the amount of PAG used. Selective excitation of the inorganic PAG in a system combining the two PAGs results in a photodecomposition product that deactivates the organic PAG, enabling nontrivial disassembly profiles under a single type of external stimulus.' article_processing_charge: No article_type: original author: - first_name: Jinhua full_name: Wang, Jinhua last_name: Wang - first_name: Tzuf Shay full_name: Peled, Tzuf Shay last_name: Peled - first_name: Rafal full_name: Klajn, Rafal id: 8e84690e-1e48-11ed-a02b-a1e6fb8bb53b last_name: Klajn citation: ama: Wang J, Peled TS, Klajn R.

Using a suite of sensitive probes of magnetism, including resonant x-ray scattering and magneto-optical polarimetry, we have discovered that ferromagnetic order onsets above \U0001D447\U0001D441 in the temperature range of the resistivity peak. The observation of inverted hysteresis in this regime shows that ferromagnetism is promoted by coupling of localized spins and itinerant carriers.

Here, we demonstrate that the DC bias strain-dependence of AC elastocaloric effect allows decomposition of the latter into symmetric (rotation-symmetry-preserving) and antisymmetric (rotation-symmetry-breaking) strain channels, using a tetragonal \r\n-electron intermetallic DyB2C2—whose antiferroquadrupolar order breaks local fourfold rotational symmetries while globally remaining tetragonal—as a showcase example. We capture the strain evolution of its quadrupolar and magnetic phase transitions using both singularities in the elastocaloric coefficient and its jumps at the transitions, and the latter we show follows a modified Ehrenfest relation. We find that antisymmetric strain couples to the underlying order parameter in a biquadratic (linear-quadratic) manner in the antiferroquadrupolar (canted antiferromagnetic) phase, which are attributed to a preserved (broken) global tetragonal symmetry, respectively. The broken tetragonal symmetry in the magnetic phase is further evidenced by elastocaloric strain-hysteresis and optical birefringence. Additionally, within the staggered quadrupolar order, the observed elastocaloric response reflects a quadratic increase of entropy with antisymmetric strain, analogous to the role magnetic field plays for Ising antiferromagnetic orders by promoting pseudospin flips. Our results demonstrate AC elastocaloric effect as a compact and incisive thermodynamic probe into the coupling between electronic degrees of freedom and strain in free energy, which holds the potential for investigating and understanding the symmetry of a wide variety of ordered phases in broader classes of quantum materials." article_number: e2302800120 article_processing_charge: No article_type: original author: - first_name: Linda full_name: Ye, Linda last_name: Ye - first_name: Yue full_name: Sun, Yue last_name: Sun - first_name: Veronika full_name: Sunko, Veronika id: 23cb1cf6-2c7a-11ef-91a4-f72fc19f20b3 last_name: Sunko orcid: 0000-0003-2724-3523 - first_name: Joaquin F. full_name: Rodriguez-Nieva, Joaquin F. last_name: Rodriguez-Nieva - first_name: Matthias S. full_name: Ikeda, Matthias S. last_name: Ikeda - first_name: Thanapat full_name: Worasaran, Thanapat last_name: Worasaran - first_name: Matthew E. full_name: Sorensen, Matthew E. last_name: Sorensen - first_name: Maja D. full_name: Bachmann, Maja D. last_name: Bachmann - first_name: Joseph full_name: Orenstein, Joseph last_name: Orenstein - first_name: Ian R. full_name: Fisher, Ian R. last_name: Fisher citation: ama: Ye L, Sun Y, Sunko V, et al.

Two laser beams are used, one as a source to locally modulate the sample temperature, and the other as a probe of sample reflectivity, which is a function of the modulated temperature. Thermal diffusivity is obtained from the phase delay between source and probe signals. We combine this technique with a microscope setup in an optical cryostat, in which the sample is placed on a three-axis piezo-stage, allowing for spatially resolved measurements. Furthermore, we demonstrate experimentally and mathematically that isotropic in-plane diffusivity can be obtained when overlapping the two laser beams instead of separating them in the traditional way, which further enhances the spatial resolution to a micron scale, especially valuable when studying inhomogeneous or multidomain samples. We discuss in detail the experimental conditions under which this technique is valuable and demonstrate its performance on two stoichiometric bilayer ruthenates: Sr3Ru2O7 and Ca3Ru2O7. The spatial resolution allowed us to study the diffusivity in single domains of the latter, and we uncovered a temperature-dependent in-plane diffusivity anisotropy. Finally, we used the enhanced spatial resolution enabled by overlapping the two beams to measure the temperature-dependent diffusivity of Ti-doped Ca3Ru2O7, which exhibits a metal–insulator transition. We observed large variations of transition temperature over the same sample, originating from doping inhomogeneity and pointing to the power of spatially resolved techniques in accessing inherent properties.' article_number: '043003' article_processing_charge: Yes (in subscription journal) article_type: original arxiv: 1 author: - first_name: F. full_name: Sun, F. last_name: Sun - first_name: S. full_name: Mishra, S. last_name: Mishra - first_name: P.

The capacity of a link (u, v) is determined by how much nodes u and v allocate for this link. Specifically, the input is a finite ordered sequence of packets that arrive in both directions along a link. Given (u, v) and a packet of weight x going from u to v, node u can either accept or reject the packet. If u accepts the packet, the capacity on link (u, v) decreases by x. Correspondingly, v’s capacity on (u, v) increases by x. If a node rejects the packet, this will entail a cost affinely linear in the weight of the packet. A link is “rechargeable” in the sense that the total capacity of the link has to remain constant, but the allocation of capacity at the ends of the link can depend arbitrarily on the nodes’ decisions. The goal is to minimise the sum of the capacity injected into the link and the cost of rejecting packets. We show that the problem is NP-hard, but can be approximated efficiently with a ratio of (1 + E) . (1 + square3) for some arbitrary E>0. acknowledgement: We thank Mahsa Bastankhah and Mohammad Ali Maddah-Ali for fruitful discussions about different variants of the problem.

Developing innovative strategies to directly transform biologically relevant molecules, without any prefunctionalization, is key to further expanding the scope and utility of such transformations. Herein, the direct access to quinazolines and pyrimidines from the corresponding unprotected 1H-indoles and 1H-pyrroles is reported, relying on the implementation of lithium bis(trimethylsilyl)amide (LiHMDS) as a novel nitrogen atom source in combination with commercially available hypervalent iodine reagents. Further application of this strategy in late-stage settings demonstrates its potential in lead structure diversification campaigns. article_processing_charge: No article_type: letter_note author: - first_name: Julia full_name: Reisenbauer, Julia id: 51d862e9-36ee-11f0-86d3-8534c85a5496 last_name: Reisenbauer - first_name: Ann-Sophie K. full_name: Paschke, Ann-Sophie K. last_name: Paschke - first_name: Jelena full_name: Krizic, Jelena last_name: Krizic - first_name: Bence B. full_name: Botlik, Bence B. last_name: Botlik - first_name: Patrick full_name: Finkelstein, Patrick last_name: Finkelstein - first_name: Bill full_name: Morandi, Bill last_name: Morandi citation: ama: Reisenbauer J, Paschke A-SK, Krizic J, Botlik BB, Finkelstein P, Morandi B.

More recently, malononitrile-based HCN donor reagents were shown to undergo the C(sp3)–CN bond activation by the nickel catalyst in the absence of Lewis acids. However, there is a lack of detailed mechanistic understanding of the challenging C(sp3)–CN bond cleavage step. In this work, in-depth kinetic and computational studies using alkynes as substrates were used to elucidate the overall reaction mechanism of this transfer hydrocyanation, with a particular focus on the activation of the C(sp3)–CN bond to generate the active H–Ni–CN transfer hydrocyanation catalyst. Comparisons of experimentally and computationally derived 13C kinetic isotope effect data support a direct oxidative addition mechanism of the nickel catalyst into the C(sp3)–CN bond facilitated by the coordination of the second nitrile group to the nickel catalyst. article_processing_charge: Yes (in subscription journal) article_type: original author: - first_name: Julia full_name: Reisenbauer, Julia id: 51d862e9-36ee-11f0-86d3-8534c85a5496 last_name: Reisenbauer - first_name: Patrick full_name: Finkelstein, Patrick last_name: Finkelstein - first_name: Marc-Olivier full_name: Ebert, Marc-Olivier last_name: Ebert - first_name: Bill full_name: Morandi, Bill last_name: Morandi citation: ama: Reisenbauer J, Finkelstein P, Ebert M-O, Morandi B.

The operational simplicity renders this protocol broadly applicable and has been successfully extended towards the direct interconversion of cyclopentadienes into the corresponding pyridines.

Primarily sites of photosynthesis, chloroplasts are unique sites also for the biosynthesis of precursors of the growth regulator auxin and for sensing environmental stress, but their role in intracellular auxin homeostasis, vital for plant growth and survival in changing environments, remains poorly understood. Here, we identified two ATP-binding cassette (ABC) subfamily B transporters, ABCB28 and ABCB29, which export auxin across the chloroplast envelope to the cytosol in a concerted action in vivo. Moreover, we provide evidence for an auxin biosynthesis pathway in Arabidopsis thaliana chloroplasts. The overexpression of ABCB28 and ABCB29 influenced stomatal regulation and resulted in significantly improved water use efficiency and survival rates during salt and drought stresses. Our results suggest that chloroplast auxin production and transport contribute to stomata regulation for conserving water upon salt stress. ABCB28 and ABCB29 integrate photosynthesis and auxin signals and as such hold great potential to improve the adaptation potential of crops to environmental cues. article_number: '7' article_processing_charge: Yes article_type: original author: - first_name: Prashanth full_name: Tamizhselvan, Prashanth last_name: Tamizhselvan - first_name: Sharmila full_name: Madhavan, Sharmila last_name: Madhavan - first_name: Christian full_name: Constan-Aguilar, Christian last_name: Constan-Aguilar - first_name: Eman Ryad full_name: Elrefaay, Eman Ryad last_name: Elrefaay - first_name: Jie full_name: Liu, Jie last_name: Liu - first_name: Aleš full_name: Pěnčík, Aleš last_name: Pěnčík - first_name: Ondřej full_name: Novák, Ondřej last_name: Novák - first_name: Albert full_name: Cairó, Albert last_name: Cairó - first_name: Mónika full_name: Hrtyan, Mónika id: 45A71A74-F248-11E8-B48F-1D18A9856A87 last_name: Hrtyan - first_name: Markus full_name: Geisler, Markus last_name: Geisler - first_name: Vanesa Beatriz full_name: Tognetti, Vanesa Beatriz last_name: Tognetti citation: ama: Tamizhselvan P, Madhavan S, Constan-Aguilar C, et al.

Working in a suitable Grothendieck ring of varieties, we show that the class of these moduli spaces converges, modulo an adequate normalisation, to a non-zero effective element, when the class of the sections goes arbitrary far from the boundary of the dual of the effective cone. The limit can be interpreted as a motivic Euler product in the sense of Bilu’s thesis. This result provides a positive answer to a motivic version of the Batyrev–Manin–Peyre conjectures in this particular setting. acknowledgement: I am grateful to Emmanuel Peyre for his help, reading and useful comments throughout the drafting process of this article. I am also very indebted to Margaret Bilu for all the constructions and properties that I used in this paper and which are due to her, especially those concerning the motivic Euler product, as well as for enlightening discussions and remarks on an earlier version of this work.

Activation of the hypothalamic–pituitary–adrenal (HPA) axis and subsequent release of glucocorticoid hormones is a key response that mobilizes fuel stores to meet energy demands1,2,3,4,5. Despite the importance of the HPA axis response, the neural mechanisms that drive its activation during energy deficit are unknown. Here, we show that fasting-activated hypothalamic agouti-related peptide (AgRP)-expressing neurons trigger and are essential for fasting-induced HPA axis activation. AgRP neurons do so through projections to the paraventricular hypothalamus (PVH), where, in a mechanism not previously described for AgRP neurons, they presynaptically inhibit the terminals of tonically active GABAergic afferents from the bed nucleus of the stria terminalis (BNST) that otherwise restrain activity of corticotrophin-releasing hormone (CRH)-expressing neurons. This disinhibition of PVHCrh neurons requires γ-aminobutyric acid (GABA)/GABA-B receptor signalling and potently activates the HPA axis. Notably, stimulation of the HPA axis by AgRP neurons is independent of their induction of hunger, showing that these canonical ‘hunger neurons’ drive many distinctly different adaptations to the fasted state. Together, our findings identify the neural basis for fasting-induced HPA axis activation and uncover a unique means by which AgRP neurons activate downstream neurons: through presynaptic inhibition of GABAergic afferents. Given the potency of this disinhibition of tonically active BNST afferents, other activators of the HPA axis, such as psychological stress, may also work by reducing BNST inhibitory tone onto PVHCrh neurons.' article_processing_charge: No article_type: original author: - first_name: Amelia May Barnett full_name: Douglass, Amelia May Barnett id: de5f6fda-80fb-11ef-996f-a8c4ecd8e289 last_name: Douglass orcid: 0000-0001-5398-6473 - first_name: Jon M. full_name: Resch, Jon M. last_name: Resch - first_name: Joseph C. full_name: Madara, Joseph C. last_name: Madara - first_name: Hakan full_name: Kucukdereli, Hakan last_name: Kucukdereli - first_name: Ofer full_name: Yizhar, Ofer last_name: Yizhar - first_name: Abhinav full_name: Grama, Abhinav last_name: Grama - first_name: Masahito full_name: Yamagata, Masahito last_name: Yamagata - first_name: Zongfang full_name: Yang, Zongfang last_name: Yang - first_name: Bradford B. full_name: Lowell, Bradford B. last_name: Lowell citation: ama: Douglass AM, Resch JM, Madara JC, et al.
