Challenges in Simultaneous Microstructuring and Hyperdoping of Germanium with Ultrafast Laser

physica status solidi (a), Volume 223, Issue 8, 22 April 2026.
Femtosecond laser processing is explored as a single‐step route to microstructure and hyperdope germanium for extended infrared absorption. Comparative experiments with and without a Ti precursor reveal that Ge's shallow green light absorption and low thermal conductivity drive intense localized melting, evaporation, and redeposition. Post‐cleaning and

Electrochemical Regioselective Chalcogenocyclizations of 2‐Alkynylbenzamides in Flow

ChemElectroChem, Volume 13, Issue 8, 15 April 2026.
A sustainable electrochemical method enables regioselective 6‐endo‐dig chalcogeno‐cyclizations of ortho‐alkynylbenzamides in continuous flow. Using diphenyl diselenide as an electroactive coupling partner, the process avoids metals and stoichiometric oxidants, offering scalable access to selenium‐containing heterocycles.

Metalloids: Semi as Metals yet Full of Antimicrobial Potential

ChemMedChem, Volume 21, Issue 7, 14 April 2026.
Metalloids such as boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), and tellurium (Te) bridge metals and non‐metals, displaying unique chemical versatility. Recent research highlights their diverse antimicrobial and therapeutic potentials, from natural products to synthetic organic and organometallic molcules, underscoring renewed ...
