MXene–MOF Hybrid Nanocomposites: Emerging Platforms for Sustainable Wastewater Treatment

EcoMat, Volume 8, Issue 7, July 2026.
This review presents MXene–MOF hybrid materials for advanced water purification. By integrating the high conductivity and hydrophilicity of MXenes with the tunable porosity of MOFs, these hybrids demonstrate superior performance in adsorption, photocatalysis, and electrochemical degradation.

Ischemia–Reperfusion Injury: Molecular Mechanisms and Therapeutic Interventions

MedComm, Volume 7, Issue 7, July 2026.
Multiorgan ischemia–reperfusion injury begins with ischemia‐induced ATP depletion and ionic imbalance, followed by reperfusion‐triggered mitochondrial ROS/RNS bursts, regulated cell death, and DAMP release. Sterile inflammation converges on endothelial–immune–coagulation crosstalk, where NETs drive immunothrombosis, no‐reflow, and remote organ injury ...

Monthly Energy, Exergy, Environmental, and Economic Performance and Green Hydrogen Production Analysis of a Flat‐Plate Solar Collector‐Driven Organic Rankine Cycle System Under Variable Mass Flow and Irradiance

ChemistryOpen, Volume 15, Issue 7, July 2026.
The feasibility of using a hybrid flat‐plate solar collector–organic Rankine cycle–proton exchange membrane system for the generation of electricity, heat, and hydrogen simultaneously is analyzed. The energy efficiency of the solar thermal system reaches 23.82%, and hydrogen production of up to 13.62 kg/month is achieved while reducing CO2 emissions ...

Enhanced Dehydrogenation and Hydrogenation Capacity of Poly(5‐Vinyl‐1‐Indanol) at Low Temperatures

Polymers for Advanced Technologies, Volume 37, Issue 7, July 2026.
ABSTRACT Redox‐active polymer‐based hydrogen carriers store hydrogen gas through chemical bonding. Although existing redox‐active polymers utilized as hydrogen storage units (e.g., fluorenone and fluorenol) demonstrate reversible hydrogenation in the presence of iridium complex catalysts, they are often hindered by low weight‐based hydrogen storage ...

Structure–activity relationship study shows versatility in substrate specificity for heterodisulfide reductase in methanogenic archaea

Protein Science, Volume 35, Issue 7, July 2026.
Abstract Hydrogenotrophic methanogens are anaerobic archaea that convert carbon dioxide and hydrogen into methane. Central to this process is the heterodisulfide reductase (Hdr), which catalyzes the reduction of the heterodisulfide made of coenzyme M and coenzyme B. In vivo, Hdr functions in association with electron‐donating modules such as the [NiFe]‐

Synergistic Hydrogen Evolution and Methanol Oxidation Over BiOIO3/Zn3In2S6 Heterojunction Photocatalyst via Interfacial Charge Steering

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Because of superior transportability and high energy capacity, methanol is regarded as a potential hydrogen carrier. Photocatalytic methanol dehydrogenation offers a sustainable and cost‐effective method for releasing hydrogen. Conventional photocatalysts face challenging obstacles, including the low catalytic efficiency and rapid ...
