Methylselenol formed by spontaneous methylation of selenide is a superior selenium substrate to the thioredoxin and glutaredoxin systems. [PDF]

PLoS ONE, 2012
Naturally occurring selenium compounds like selenite and selenodiglutathione are metabolized to selenide in plants and animals. This highly reactive form of selenium can undergo methylation and form monomethylated and multimethylated species. These redox

Intermediate Phases, structural variance and network demixing in chalcogenides: the unusual case of group V sulfides

, 2008
We review Intermediate Phases (IPs) in chalcogenide glasses and provide a structural interpretation of these phases. In binary group IV selenides, IPs reside in the 2.40 < r < 2.54 range, and in binary group V selenides they shift to a lower r, in the 2 ...

Stretchable p/n‐Pair Thermoelectric Fibers Based on Core (Ag)–Shell (Ag2Se) Structure for Wearable Electronics

Advanced Functional Materials, EarlyView.
Stretchable p/n‐pair Ag@Ag2Se TE fibers are developed for next‐generation fiber‐based electronics. The TE fibers maintain excellent electrical conductivity and a high Seebeck coefficient under strain. Integrated into textiles, they enable simultaneous temperature and strain sensing, as well as energy harvesting, offering great potential for ...

Silver Ion‐Mediated [hk1]‐Oriented Sb2Se3 Crystal Growth for Efficient Photoelectrochemical Hydrogen Evolution

Advanced Functional Materials, EarlyView.
Ag+‐mediated hydrothermal crystal engineering promotes preferential [hk1]‐oriented growth of Sb2Se3 via an ultrathin MoOx interlayer, improving crystallinity and suppressing non‐radiative recombination. The optimized Ag+ treatment photocathode delivers 24.7 mA cm−2 at 0 VRHE and improved stability, revealing an ion‐modulated route to high‐performance ...

Indirect Band Edge and Chain‐Locked Linear Dichroism in the Quasi‐1D Van der Waals Antiferromagnet AgCrP2S6

Advanced Functional Materials, EarlyView.
AgCrP2S6 reveals a momentum‐indirect band edge (≈1.35 eV) and chain‐locked linear dichroism: the first direct transitions emerge at 1.6–1.8 eV for E||a. Resonant Raman and photoemission corroborate this assignment. In ACPS/graphene heterostructures, photocurrent turns on above ≈1.5 eV and follows the same polarization selection rules (anisotropy ≈0.53),

Selenium and hydrogen selenide: essential micronutrient and the fourth gasotransmitter?

Intensive Care Medicine Experimental, 2019
Selenium (Se) is an essential micronutrient required by organisms of diverse lineage. Dietary Se is converted to hydrogen selenide either enzymatically or by endogenous antioxidant proteins.
