Incorporation of Organic Counter‐Cations Into Poly(Heptazine Imide) Networks for Promoting Proton‐Coupled Electron Transfer During Photocatalytic H2O2 Evolution

Angewandte Chemie, EarlyView.
Incorporation of N‐based onium ions into the ionic framework of poly(heptazine imide) was obtained via protonation‐deprotonation of PHI frameworks arising from a parent Na‐containing analogue. Particularly, methylammonium moieties, through their small molecular size, hydrogen bonding capabilities and rotational mobility, appear to stabilize ...

Cyanide overproduction impairs cellular bioenergetics in Down syndrome

Neurotherapeutics
Cyanide exerts its toxic effects primarily by inhibiting mitochondrial Complex IV (Cytochrome c oxidase, CCOx). Recent studies have shown that mammalian cells can endogenously produce cyanide from glycine via a lysosomal pathway.

Vacancy‐Driven Ni Exsolution in Prussian Blue Analogues Creates Cooperative Defect–Metal Sites for Alkaline Hydrogen Evolution

Advanced Science, EarlyView.
Multimetal Prussian blue analogues (PBAs) are converted by low‐temperature Ar annealing into a cavity/CN‐vacancy architecture that triggers in situ Ni exsolution, creating dense Ni‐PBA interfacial motifs. These motifs optimize water dissociation and H* adsorption in alkaline media, delivering markedly accelerated HER kinetics and long‐term stability ...

Stacking the Deck to Make Materials With Atypically Short Heterometallic d8 M(II)···Au(III) Bonds

Angewandte Chemie, EarlyView.
Tetracyanoplatinate(II) and tetracyanoaurate(III), through self‐assembly in the presence of KCl, crystallize from water to form a one‐dimensional chain featuring the first reported PtII···AuIII metallophilic interaction with a very short distance of ∼3.0 Å between the metal centers.

High‐Performance Transparent Solid Polymer Electrolyte Based on Copolymer of Deep Eutectic Electrolyte and Methyl Methacrylate for Electrochemical Devices

Advanced Science, EarlyView.
A copolymerization strategy using a polymerizable deep eutectic electrolyte with MMA forms efficient ion‐transport pathways while maintaining excellent transparency. The solid polymer electrolyte simultaneously achieves 17.8 MPa mechanical strength and 1.43 mS cm−1 ionic conductivity, enhancing long‐term cycling stability in Li|LFP batteries and ...

The atmospheric chemistry of hydrogen cyanide (HCN) [PDF]

, 1983
Since 1981, three groups have reported spectroscopic detections and measurements of hydrogen cyanide in the atmosphere. HCN concentrations (volume mixing ratios) of (1.5-1.7) x 10-10 appear to characterize the stratosphere and the Northern Hemisphere's ...

Determination of Cyanide in Biological and Non-biological Matrices by Headspace Gas Chromatography coupled to Flame- Ionization Detector

Arab Journal of Forensic Sciences & Forensic Medicine, 2015
A simple, rapid and reliable method for quantitation of cyanide was developed on a headspace gas chromatograph coupled to a flame ionization detector using a HP-Innovax (Polyethylene glycol bonded) column on an Agilent 7890A GC. Cyanide in blood or other

Biomimetic Nanoplatform for Dual Target Nano‐Metabolic Therapy in Diabetes‐Associated Biofilm Infections

Advanced Science, EarlyView.
A biomimetic GOx/Arg‐loaded nanoplatform produces nitric oxide through an in situ catalytic cascade reaction, enabling dual‐target metabolic regulation in diabetes‐associated biofilm infections. Bacterial metabolism is disrupted, and macrophage immunometabolism is reprogrammed, resulting in biofilm eradication, immune restoration, and enhanced ...
