EPR spectroscopy applied to the study of the TEMPO mediated oxidation of nanocellulose
(Elsevier, 2015-09-30)
Two different methods of pH control were used in the synthesis of 2,2,6,6-tetramethylpiperidine-1-oxyl(TEMPO) oxidized cellulose nanocrystals (CNC) and the reaction kinetics and degree of oxidation wereinvestigated. In ...
Nanozeolites as support for laccase immobilization: Application to mediated glycerol oxidation
(2021-09-25)
This study investigated the use of nanozeolites as support for laccases from P. ostreatus (LPO), Aspergillus sp (LAsp) and A. bisporus (LAB) immobilization applied to 2,2,6,6-tetramethylpiperidine-N-oxyl (TEMPO) mediated ...
Structural determination and chemical modifications of the polysaccharide from seeds of Prosopis chilensis Mol. (Stuntz)
(SOCIEDAD CHILENA DE QUIMICA, 2006-03)
The polysaccharide extracted from Prosopis chilensis seeds in acidic medium showed by total hydrolysis and gas-liquid chromatography analysis of the alditol acetates to be composed of galactose and mannose in the molar ...
