The Influence of Non-selective Oxidation on Differently Pre-treated Cotton Yarns Properties
Medžiagotyra, 2016 Differntly pre-treated cotton yarns were subjected to non-selective oxidation with perchloric acid and the effects of pre-treatment processes on oxidation were studied through functional groups quantity, and degradation through mechanical properties and ...

The Influence of Carboxyl-Functionalized Carbon Dots on Ethanol Selectivity in Gas Sensing
Chemosensors, 2023 For semiconductor tin dioxide (SnO2) materials, the oxygen adsorption theory often struggles to explain their selectivity towards specific gases. Therefore, it is worth considering altering the surface functional groups of SnO2 to modify its surface ...

Essential carboxyl groups in yeast hexokinase [PDF]
FEBS Letters, 1974 Although a great deal of kinetic data are available on yeast hexokinase and several schemes have been proposed, the mechanism of its action is far from being understood [ 1,2] . It is generally agreed, however, that the transphosphorylation step requires the formation of a ternary complex between the enzyme and its substrates, ATP-Mg and D-glucose ...

Stabilization of colloidal palladium particles by a block copolymer of polystyrene and a block containing amide sidegroups [PDF]
, 1996 A block copolymer of polystyrene and poly(tert-butylmethacrylate) was prepared by anionic polymerization. The ester groups of the poly(tert-butylmethacrylate) were hydrolyzed, after wich the remaining carboxyl groups were reacted with pyrrolidine.
