Water, Alcohols, Amines, and Amides as Formal Hydrogen‐Atom‐Transfer Reagents Through Activation With Redox‐Active Lewis Acids

Angewandte Chemie, Volume 138, Issue 39, 21 September 2026.
Protic molecules containing strong O─H or N─H bonds typically resist hydrogen‐atom abstraction because of the high reactivity of the resulting heteroatom‐centered radicals. However, association of the protic molecules with redox‐active Lewis acids can provide powerful hydrogen‐atom donors or proton‐coupled‐electron‐transfer reagents.

A model for DMFC cathode impedance: The effect of methanol crossover

Electrochemistry Communications, 2012
Abstract A model for impedance of DMFC cathode is developed. The model shows formation of the methanol oxidation reaction dominating domain (virtual anode) at the membrane interface. With the growth of the methanol crossover rate, the thickness of the virtual anode increases.

Effects of SGLT‐2 Inhibitors on Plasma Concentrations and Renal Clearance of the Risk Marker Trimethylamine‐N‐Oxide in Patients With Type‐2 Diabetes

Endocrinology, Diabetes &Metabolism, Volume 9, Issue 6, November 2026.
Treatment with empagliflozin or dapagliflozin was associated with a modest increase in plasma concentration of TMAO in Type 2 diabetes patients. These findings suggest a possible class effect of SGLT‐2 inhibitors. Whether this effect impacts the overall clinical benefits of SGLT‐2 inhibitors needs to be subject to further investigation.

Borylcyclopropanes: Synthetic Strategies and Applications

Angewandte Chemie, Volume 138, Issue 37, 7 September 2026.
Borylcyclopropanes (cyclopropanes bearing a boron substituent) sit at the intersection of two privileged frameworks in synthesis. This review provides the first exhaustive survey of their chemistry, spanning metal–carbene, nucleophilic cyclization, radical, hydroboration, and C─H activation routes, and documenting applications in medicinal chemistry ...

Engineering Tin Foam Electrodes for High‐Rate CO2 Reduction: A Pathway to Sustainable Formic Acid Production

ChemElectroChem, Volume 13, Issue 19, 1 October 2026.
Highly porous Sn foam electrodes prepared by dynamic hydrogen bubble template exhibit high selectivity for CO2 reduction to formic acid. No decline of catalytic activity or selectivity, or morphological modifications were observed after long‐term electrolysis operating at high current densities.
