Enhancing Sulfur Redox Kinetics of Carbon‐Supported Cobalt Diselenide Electrocatalysts via an Anion‐Doping Strategy

open access: yesChemElectroChem, Volume 13, Issue 12, 17 June 2026.
This work presents an anion‐doping strategy to regulate the structure and electronic properties of CoSe2 electrocatalysts through partial substitution of Se by S species. The optimized CoSeS electrocatalyst exhibits enhanced LiPSs adsorption and accelerated redox conversion for high‐performance Li–S batteries. The growing demand for high‐energy‐density

The structure of niobium-doped MoSe2 and WSe2

open access: yesBulletin of the Chemical Society of Ethiopia, 2008
Polycrystalline niobium-doped molybdenum and tungsten diselenides were synthesized in silicatubes sealed under secondary vacuum. They were characterized by scanning electron microscopy, electrondiffraction, X-ray diffraction, chemical composition and EDX

Single‐Photon Emission From TMDCs through Strong Coupling to EQ Plasmon Modes of an Au Metasurface

open access: yesNanophotonics, Volume 15, Issue 11, 13 June 2026.
Compact, deterministic solid‐state single‐photon sources that operate at room temperature and integrate with planar nanophotonics are essential for the development of scalable quantum photonic technologies. This work presents a TMDC monolayer strongly coupled to a gold (Au) metasurface featuring an electric quadrupole mode, enabling high‐purity single ...

A novel and efficient method for the synthesis of dibenzyl diselenides

open access: yes, 2004
A novel and efficient method for the synthesis of dibenzyl diselenides is described. Aromatic aldehydes were reduced via selenation with Se/CO/H2O in DMF under atmospheric pressure to give dibenzyl diselenides in high ...

Rhodium-Catalyzed Reductive Coupling of Disulfides and Diselenides with Alkyl Halides, Using Hydrogen as a Reducing Agent

open access: yes, 2016
We have established that RhCl(PPh3)3 catalyzes a reductive coupling of disulfides and diselenides with alkyl halides in the presence of triethylamine using hydrogen as a reducing agent.

A new approach to access of 4-organoselenylisoxazoles using the diorganyl diselenide/Oxone® oxidant system

open access: yesDiscover Chemistry
In this work, we describe a new protocol to the synthesis of 4-organoselenylisoxazoles using an oxidant system. This transition metal-free method explores the reaction between 1,3-diarylprop-2-yn-1-one O-methyloximes and diorganoyl diselenides in ethanol

Nucleophilic Perfluoroalkylation of Aldehydes, Ketones, Imines, Disulfides, and Diselenides

open access: yes, 2016
Using a procedure analogous to that developed for nucleophilic trifluoromethylation, the perfluoroalkyl anion reagents created by mixing C2F5I and n-C4F9I with tetrakis(dimethylamino)ethylene (TDAE) were effective in their nucleophilic reactions with ...

Small-Molecule Diselenides Catalyze Oxidative Protein Folding in Vivo

open access: yes, 2016
Prokaryotic cells normally rely on periplasmic oxidoreductases to promote oxidative protein folding. Here we show that simple diselenides can also facilitate the conversion of dithiols to disulfides in vivo, functionally replacing one such oxidoreductase,
