Multi‐Responsive Bowl‐Shaped Janus Nanomotors Based on Polyitaconic acid/Polypyrrole on the Surface of Iron Oxide Nanoparticles with Chemical, Electrical, and Magnetic Field Actuation for Targeted Drug Delivery Applications

open access: yesAdvanced NanoBiomed Research, EarlyView.
Bowl‐shaped Janus nanomotors with platinum, iron oxide, and polypyrrole integrate catalytic, magnetic, and electric propulsion for targeted drug delivery. They demonstrate controlled, directional motion under varying pH and hydrogen peroxide conditions, with optimal performance in neutral media.

Harnessing the Reactivity of Sulfinate Salts With Cystine: An Umpolung Approach to Residue‐Specific Peptide Modification

open access: yesAngewandte Chemie, EarlyView.
While cysteine is widely employed as a nucleophilic handle for peptide modification, the electrophilicity of the oxidized form, cystine, is rarely exploited. This study describes a mild, photochemical coupling of sulfinate salts with peptide disulfides.

Acetylene Semi‐Hydrogenation by Photocatalysis

open access: yesAngewandte Chemie, EarlyView.
Photocatalytic acetylene semi‐hydrogenation is an emerging light‐driven route to polymer‐grade ethylene, offering a mild alternative to energy‐intensive thermocatalysis. By replacing H2 co‐feed with water or other proton sources, these systems can achieve high selectivity under ambient conditions.

Flavin Catalysts in Organic Synthesis

open access: yesAngewandte Chemie, EarlyView.
Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.
