A PVA matrix was used to suppress infiltration and coffee-ring effects during colorimetric analysis on a paper substrate and improve the trace-level detection of nickel ions (Ni2+) in environmental samples. To improve the color response, a cross-linked PVA matrix was used to anchor the indicator reagent of Ni2+ on the surface of the porous paper substrate as well as reduce evaporation flow by incr...... hiện toàn bộ

A carboxylate-type liquid zwitterion, OE2imC3C, has been recently reported as a unique solvent as a class of ionic liquids with distinctive properties and functions such as cellulose dissolution ability and low toxicity to fermentative microoganisms. Therefore, OE2imC3C first enabled successive conversion of biomass to bioethanol in the same reaction pot. However, the reagent, 1-bromo-2-(2-methoxy...... hiện toàn bộ
The effect of sulfate half-ester groups on the mechanical performance of cellulose nanocrystal-natural rubber compositesSpringer Science and Business Media LLC - Tập 30 - Trang 8929-8940 - 2023

Cellulose nanocrystals (CNCs) are commercially produced via hydrolysis by sulfuric acid, resulting in the formation of sulfate half-ester groups on the surface of the nanoparticles. The sulfate half-esters promote good colloidal stability but could affect other properties of the CNCs. To study the impact of the sulfate half-ester groups on the mechanical properties of CNC-natural rubber composites...... hiện toàn bộ
The effect of adsorbed carboxymethyl cellulose on the cotton fibre adsorption capacity for surfactantSpringer Science and Business Media LLC - Tập 13 - Trang 655-663 - 2006

The research reported in this paper demonstrates that the capacity of cotton fibres to adsorb cationic surfactants as well as the rate of the adsorption process can be increased by adsorbing carboxymethyl cellulose (CMC) onto the fibre surfaces; in addition, the adsorption can be restricted to the fibre surface. CMC was deposited by means of adsorption from an aqueous solution. The adsorption of N...... hiện toàn bộ
