Vacancy Engineered Zero‐Valent Iron Steer Hydrogen Spillover toward Per‐ and Polychlorinated Organics Rapid Complete Dechlorination

Advanced Science
The elevated toxicity and persistent bioaccumulative propensity of per‐ and polychlorinated organics (PCOs) pose a substantial environmental hazard; however, current dechlorination technologies encounter challenges in surmounting the cumulative reductive

Oxygen‐Tunnel Indium Tin Oxide Vertical Channel Transistors with Enhanced Current Density and Reliability for Monolithic 3D Compute‐In‐Memory Systems

Advanced Functional Materials, EarlyView.
Oxygen‐tunnel (OT) indium tin oxide (ITO) vertical channel transistors (VCTs) enable reliable, high‐density gain‐cell memory for monolithic 3D integration. A sandwiched SiN/SiO2/SiN OT stack selectively regulates oxygen transport, suppressing parasitic electrode oxidation while stabilizing channel oxygen vacancies, thereby suppressing carrier injection

Modeling Low-Barrier Hydrogen Bonds and Solution Effects [PDF]

, 2013
In the first project, we modeled low barrier hydrogen bond systems, which have a unique energy profile. Classification of a hydrogen bond as a low barrier hydrogen bond requires assignment of the experimental vibrational spectrum, as well as prediction ...

Predicting the Position of the Hydrogen Atom in the Short Intramolecular Hydrogen Bond of the Hydrogen Maleate Anion from Geometric Correlations [PDF]

, 2017
The position of the hydrogen atom inside the strong and short intramolecular hydrogen bond of the hydrogen maleate anion strongly varies depending on the crystalline environment.

Carbon fiber confined mixed Ni‐based crystal phases with interfacial charge redistribution induced by high bond polarity for electrochemical urea‐assisted hydrogen generation

Carbon Energy
Interfacial electronic structure modulation of nickel‐based electrocatalysts is significant in boosting energy‐conversion‐relevant urea oxidation reaction (UOR). Herein, porous carbon nanofibers confined mixed Ni‐based crystal phases of Ni2P and NiF2 are

In silico approaches of gandarusa (Justicia gendarussa Burm. f.) potential for osteoporosis prevention via EGF pathway [PDF]

Journal of Pharmacy & Pharmacognosy Research
Context: On a cellular level, osteoporosis is a metabolic bone disease caused by osteoclastic bone resorption that is not offset by osteoblastic bone synthesis. This increases the risk of fractures by making bones weak and brittle.

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films

Advanced Functional Materials, EarlyView.
Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...

Quasi-one-dimensional enaminone-linked covalent organic frameworks for efficient CO₂ photoreduction

Nature Communications
Quasi-one-dimensional covalent organic frameworks have emerged as promising platforms for photochemical energy conversion due to their low density of basal sites, abundant edge sites, and dual-chain-like structure.

Formation and Reversible Cleavage of an Unusual Trisulfide-Bridged Binuclear Pyridine Diimine Iridium Complex

Inorganics
Iridium pyridine diimine (PDI) complexes provide a versatile platform for highly reactive Ir–nitrido species with pronounced multiple-bond character, capable of activating H–H, C–H, Si–H, and even C–C bonds.
