Beyond Single‐Active Sites: The Emergence of High‐Entropy Perovskites in Energy and Environment Catalysis

ChemSusChem, Volume 19, Issue 13, 14 July 2026.
This review examines high‐entropy perovskites (HEPs) as a promising catalyst platform for energy and environmental applications. The focus is on configurational entropy engineering, design and synthesis, and computational understanding. These materials possess tunable active sites, enhanced stability, and improved electronic interactions, leading to ...

Relative Resiliency of Bioanode Electrochemical Resistances with Changes in Interelectrode Spacing in Microbial Electrolysis Cells

ChemElectroChem, Volume 13, Issue 13, 2 July 2026.
Hydrogen gas can be produced from organic matter in microbial electrolysis cells (MECS) using certain microorganisms on the anode and a catalyst on the cathode. We show that materials and different electrode distances change gas production rates, but the intrinsic properties of the microbes to produce current were unaffected by subsequent changes in ...

Electrochemical Investigation of Temperature‐Dependent Zinc Anode Behavior for Zn–MnO2 Batteries Under Alkaline and Mildly Acidic Conditions

ChemElectroChem, Volume 13, Issue 13, 2 July 2026.
Temperature governs ion transport and charge transfer kinetics in zinc‐based batteries. We compare 6M KOH (potassium hydroxide) and 2M ZnSO4 (zinc sulfate) electrolytes across 0°C to 40°C, finding analogous temperature dependencies in diffusion rates, overpotentials, plating morphology, and Coulombic efficiency.

A Review of Breath Sensing for Disease Monitoring and Diagnosis: Breathomics, Artificial Intelligence, and Nanomaterials for the Future of Medicine

Advanced Sensor Research, Volume 5, Issue 7, July 2026.
Breathomics is established as a non‐invasive diagnostic strategy by combining volatile organic compound biomarkers, nanomaterial‐based sensor arrays, and AI‐driven classification. Key diseases, sensing materials, and analytical challenges are critically compared, revealing how portable, data‐enabled breath platforms are moving toward clinically useful ...
