Asymmetric Single‐Atom Catalysts Govern Diffusible and Non‐Diffusible Non‐Radical Pathways for Selective Degradation of Antibiotic Resistance Genes

Advanced Science, EarlyView.
Asymmetric single‐atom metal‐nitrogen‐carbon catalysts modulate the non‐radical pathway during peroxymonosulfate (PMS) activation. A fundamental contrast was revealed between diffusible singlet oxygen (1O2) and non‐diffusible electron‐transfer pathways (ETP) in antibiotic resistance gene (ARG) degradation.

Heat Stress Promotes Fibroblast‐Derived WNT5A Secretion Through m6A Modification to Activate Melanogenesis

Advanced Science, EarlyView.
Heat stress promotes WNT5A secretion from fibroblasts via METTL3/YTHDC1‐dependent m6A methylation. Subsequently, WNT5A binds to FZD10 on melanocytes, activating β‐catenin‐driven melanogenesis. ABSTRACT As the impact of global warming continues to intensify, the effects of heat stress on the skin are becoming increasingly evident.

ATL2 Recruits TRAK1 to Promote Mitochondrial Transport at ER–Mitochondria Contact Sites

Advanced Science, EarlyView.
ABSTRACT Mitochondrial transport and distribution are crucial for cellular homeostasis, yet whether and how they are regulated by endoplasmic reticulum (ER)–mitochondria contact sites remains unclear. Here, we demonstrate that the ER protein atlastin‐2 (ATL2) orchestrates mitochondrial transport and distribution by promoting assembly of the transport ...

Oral Glycine and Sodium Thiosulfate for Lethal Cyanide Ingestion [PDF]

, 2017
Accidental or intentional cyanide ingestion is an-ever present danger. Rapidly acting, safe, inexpensive oral cyanide antidotes are needed that can neutralize large gastrointestinal cyanide reservoirs.

An Electrochemical Study of Gold Dissolution in Thiosulfate Solution with Cobalt–Ammonia Catalysis

Metals, 2022
Alkali agents could be used to enhance the extraction of zinc from solution, but excess alkali can lead to emulsification of the solution. In this study, the redox couples of Co(III)/Co(II) could be formed based on the thermodynamic analysis, and ...

Activating Ionic Carbon Nitrides via Epitaxial Dyadic Coupling for Efficient Solar‐Driven H2O2 Generation

Advanced Science, EarlyView.
Epitaxial integration of a C1N1 phase onto KPHI creates a dyadic charge‐transfer nanostructure with strong interfacial electronic coupling. This architecture drives directional electron transfer from KPHI to C1N1, enabling efficient cocatalyst‐free solar H2O2 production.
