Adenine nucleotide translocator and ATP synthase cooperate in mediating the mitochondrial permeability transition

The Journal of Physiology, EarlyView.
Abstract figure legend Both ATP synthase and adenine nucleotide translocator (ANT) play key roles in mediating the permeability transition. The contribution of ANT becomes evident in the presence of atractylate (ATR) at pH 6.5, a condition that prevents ATP synthase channel activity. At pH 7.4, this effect is minimal, suggesting a critical role for ATP

Decoupling Electronic Activation and Pore Connectivity in Acidic Oxygen Reduction on Metal‐Free Biomass‐Derived Carbon Catalysts

ChemElectroChem, Volume 13, Issue 16, 18 August 2026.
Acidic ORR on biomass‐derived carbon is described by partially separable electronic and transport contributions. Defect‐derived electronic states are associated with the onset region, whereas connected three‐dimensional pore pathways are associated with accessibility in the transport‐influenced regime.

Interfacial Acid Sites‐Mediated ZnO‐Based Electrocatalysts for Sustainable Dual‐Pathway H2O2 Production and Rechargeable Zn‐H2O2 Electrochemical Cell

Advanced Materials, Volume 38, Issue 44, 7 August 2026.
In this work, a synergistic strategy introduces interfacial acid sites, oxygen vacancies, and built‐in electric field into ZnSe/ZnO heterojunction to optimize its electronic structure and electrode micro‐environment. This overcomes sluggish oxygen reduction reaction kinetics and low H2O2 selectivity, achieving record H2O2 productivity (754.4 M gcat−1 ...

Potassium Thiocyanate‐Assisted Enhancement of Slot‐Die‐Coated Perovskite Films for High‐Performance Solar Cells

Small Science, 2021
Slot‐die coating is highly promising for scaled deposition of metal halide perovskite thin films. However, the power conversion efficiencies (PCEs) of slot‐die‐prepared perovskite solar cells (PSCs) still lag behind their spin‐casted counterparts.

Electron‐Donating Multifunctional Molecules: A Strategy for High‐Performance Perovskite Solar Cells

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Multifunctional molecules containing electron‐donating groups are critically important in perovskite solar cells (PSCs), including defect passivation, crystallization modulation, energy level alignment, and other functions. This review systematically examines the application and research progress of such multifunctional molecules in PSCs ...
