Azole γ‐Peptides Helix Switching via Heterocycle Substitutions

Angewandte Chemie, EarlyView.
Heterocycle substitution in azole‐based γ‐amino acids enables control over the helical shape of heterocyclic γ‐peptides. S↔N permutation in thiazole residues switches a canonical 9‐helix into a flexible helix exhibiting discontinuous hydrogen bonding.

Exfoliated‐MoS2 Gradual Resistive Switching Devices as Artificial Synapses

Advanced Electronic Materials, EarlyView.
A vertical memristor based on untreated, exfoliated MoS2 is presented, revealing gradual resistive switching governed by Schottky barrier modulation at the MoS2/metal interface from the trapping/detrapping of charges. Furthermore, the device emulates synaptic‐like plasticity functions, including: potentiation, depression, and spike‐amplitude‐dependent ...

Crystal structure of (Z)-2-fluorobenzyl 2-(5-fluoro-2-oxoindolin-3-ylidene)hydrazinecarbodithioate dimethyl sulfoxide monosolvate

Acta Crystallographica Section E: Crystallographic Communications
The title solvate, C16H11F2N3OS2·C2H6OS, crystallized with two independent molecules (A and B) in the asymmetric unit. Both molecules exhibit an L-shaped geometry but slightly differ in the orientation of the o-fluorobenzyl ring with respect to the 5 ...

Charge Transport in All‐Inorganic CuInSe2 Nanocrystal Transistors: Linking Material Design and Device Performance

Advanced Electronic Materials, EarlyView.
This work explores how colloidal CuInSe2 nanocrystals form functional field‐effect transistors when their native ligands are replaced with short inorganic species that promote charge transport. By systematically adjusting nanocrystal dimensions, surface treatments, film characteristics, and device architecture, the study maps the resulting electronic ...

Deep Learning–Based Extraction of Promising Material Groups and Common Features from High‐Dimensional Data: A Case of Optical Spectra of Inorganic Crystals

Advanced Intelligent Discovery, EarlyView.
We report a novel interpretation method for deep learning models based on feature extraction and clustering. Applying this method to an atomistic line graph neural network (ALIGNN) model trained on optical absorption spectra of 2,681 inorganic compounds obtained from first‐principles calculations, we successfully identify key factors underlying ...

Ammonium Oxathioamidate

Molbank
Ammonium oxathioamidate (1) was synthesised by the reaction between O-ethyl-thioxamate (oxalic acid-1-amide-2-O-ethyl ester) and ammonium hydrogen carbonate in water solution. Compound 1 was fully characterised by both microanalytical (elemental analysis,

Photocatalysis with Chalcogen Bonds

In a recent prebiotically plausible synthesis of 2'-deoxyribose-2-thiouridine, UV irradiation and aqueous bisulfide were employed to conduct the photoreduction of 2',2-thioanhydrouridine, resulting in the formation of the non-canonical thiopyrimidine nucleoside.
