Synthesis of a 3-Thiomannoside
(American Chemical Society, 2016-04)
An efficient and straightforward synthesis of a novel 3-thiomannoside derivative (1,2,4,6-tetra-O-acetyl-3-S-acetyl-3-thio-β-d-mannopyranoside) was developed starting from levoglucosenone. A xanthate-thiocarbonate exchange ...
N-Vinyltriazoles: A New Functional Monomer Family through Click Chemistry
(AMER CHEMICAL SOC, 2010)
The synthesis, polymerization behavior, and physical properties of a third vinyltriazole monomer family, the isomeric 1,4-N-vinyltriazoles, are reported. Xanthate-based reversible addition-fragmentation and transfer (RAFT) ...
Rapid estimation of gamma number of viscose by UV Spectrophotometry
(Associação Brasileira Técnica de Celulose e Papel, 2014-02)
Viscose process is the most important method for industrial cellulose dissolution. The degree of substitution (DS) is an important parameter in cellulose derivatives, and it is usually expressed as a gamma number (γ No.). ...
Assessment of the floatability of chalcopyrite, molybdenite and pyrite using biosolids and their main components as collectors for greening the froth flotation of copper sulphide ores
(2014)
Biosolids and representative compounds of their main components – humic acids, sugars, and proteins – have been tested as possible environment-friendly collectors and frothers for the flotation of copper sulphide ores. The ...
Biodepression of copper-activated pyrite with acidithiobacillus ferrooxidans in flotation with fresh and seawater
(MDPI, 2021)
Acidithiobacillus ferrooxidans has been shown to be a good depressant of pyrite in freshwater and seawater flotation. However, the effect of these bacteria over copper-activated pyrite has not been studied. At the industrial ...
Coexistence of phosphatidylcholine-specific phospholipase C and phospholipase D activities in rat cerebral cortex synaptosomes
(Springer Heidelberg, 2006-03)
DAG derived from phosphatidylcholine (PtdCho) acts as a lipid second messenger. It can be generated by the activation of phospholipase D (PLD) and the phosphatidic acid phosphohydrolase type 2 (PAP2) pathway or by a ...
