2.1.2.1 Selenium Dioxide Based Reagents 2.1.2.1.1 Stereochemistry and mechanism Selenium dioxide is still regarded as the most reliable and predictable reagent for this transformation, particularly for more substituted alkenes. A number of reviews of the reaction are available in the literature.1 Selen...
which involves a mixed phase of high-mobility tellurium within an amorphous tellurium suboxide matrix (Te–TeOx, 0 < x ≤ 2). The thermal evaporation method was used to deposit amorphous Te–TeOxthin films by evaporating tellurium dioxide (TeO2) powder, followed by low-temperature...
The chemicals used in the experimental synthesis include 5,6-diamino-1,10-phenanthroline, selenium dioxide (SeO2), 2-acetylpyridine, p-tolualdehyde, ammonium hydroxide, peroxidation benzoin formyl (BPO), n-bromosuccinimide (NBS), triphenylphosphine, ruthenium (III) chloride hydrate (RuCl3⋅H2O), ...

Endothermic types absorb energy and typically release carbon dioxide and moisture upon decomposition, while the exothermic types release energy and usually generate nitrogen when decomposed. The overall gas yield and pressure of gas released by exothermic foaming agents is often higher than that of ...
One of the most widely employed methods to produce red Nano-selenium is the chemical reduction of selenium salts such as selenate, selenite, and selenium dioxide in the presence of ascorbic acid as a reducing agent [10,11]. Deoxyribonucleic acid (DNA) is the main molecular target for most ...
After 30 min of reaction, a 6.2 mM ferulic acid (Fa) solution prepared in 96% ethanol was gradually added to the mixture in a molar ratio of chitosan monomer unit:Fa of 1:0.1 (considering both acetylated and non-acetylated monomer units, i.e., the average molecular weight of monomer ...
