The chemo-enzymatic modification of cellulose nanofibers (CNFs) using laccase as biocatalysts and TEMPO or 4-Amino-TEMPO as mediators under mild aqueous conditions (pH 5, 30 °C) has been investigated to introduce surface active aldehyde groups. 4-Amino TEMPO turned out to be kinetically 0.5-times (50%) more active mediator, resulting to oxoammonium cation(More)
The effect of the antimicrobial agent TMPAC (3-(trimethoxysilyl)-propyldimethyloctadecyl ammonium chloride) on the cellulase activity on model cellulose substrate was investigated by in situ-null ellipsometry. The cellulases used were extracted from Trichoderma viride and Aspergillus niger, and the model cellulose film was prepared by spin-coating silicon(More)
The adsorption of chemically similar but differently oxygen reactive phenolic-acid derivatives on the Ti-nanotubes (TiNTs) surfaces to increase and/or broaden their photo-induced activity was studied using Raman and X-ray photoelectron spectroscopies combined with zeta-potential analyses. Photo-catalytic activities and stabilities of newly synthesized(More)
