Identification of Natural Isonitriles Through Ligation to an Azomethine Imine Probe

Chemistry – A European Journal, EarlyView.
The azomethine imine (AMI)–isonitrile (NC) ligation allowed for the chemoselective detection of natural isonitriles in bacteria and fungi. The reactivity‐based screening establishes a new stereogenic center, thereby allowing for facile distinction between chiral and achiral isonitriles. The work also unraveled a unique reactivity of isonitriles bearing

Recent Advances on Self‐Powered Metal Halide Perovskite Photodetectors

EcoEnergy, EarlyView.
This review outlines that metal halide perovskites, with high absorption coefficient and carrier mobility, enable self‐powered photodetectors. These devices operate without external power, with improvements via structural optimization, film engineering, and defect passivation, showing promise in smart sensors and Internet of Things applications ...

Synthesis and crystal structure of N1,N2-dimethylethanedihydrazide

Acta Crystallographica Section E: Crystallographic Communications
The title compound, N1,N2-dimethylethanedihydrazide, C4H10N4O2, was obtained by the methylation of oxalyl dihydrazide protected with phthalimide. The molecule is essentially non-planar with a dihedral angle between the two planar hydrazide fragments of ...

Ultra‐High Strength and Environmentally Stable Fluorinated Solid‐State Ion‐Conductive Elastomers with Folding‐Paper‐Structured Triboelectric Nanogenerators for Wave Energy Harvesting

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this work, a polyurethane‐based fluorinated SICEs with excellent mechanical properties (7.35 MPa and 61.4 MJ m−3), conductivity (4.2 × 10−4 S cm−1), and harsh environmental resistance were prepared by a “three birds with one stone” strategy that combines multiple interactions with fluorine effects. The paper‐folding TENG is capable of harvesting not
