Bacterial cellulose is a biological polymer with a variety of extraordinary properties which make it a functional material for different industrial fields. This work aimed at monitoring the effects of three different organic acids and nanoparticles on the production, water holding capacity and structural characteristics of bacterial cellulose. Different concentrations of organic acids and nanop...

Hydroxypropyl cellulose (HPC) is a widely commercialized derivative. While it typically used as binder or stabilizer for foods and pharmaceuticals, can also form cholesteric liquid crystal in aqueous solution. Moreover, at high HPC concentrations this lyotropic thermotropic mesophase known to reflect structural color. However, remains challenge retain vibrant coloration into the solid state. He...

Nanofibrillated cellulose (NFC) from wood is an interesting material constituent of high strength and high aspect ratio, which easily forms networks through interfibril secondary bonding including hydrogen bonds. This has been exploited in preparation of new materials, which extend the range of properties for existing cellulosic materials. The objective is to explore processing-structure and st...

in this article, we survey the asymptotic stability analysis of fractional differential systems with the prabhakar fractional derivatives. we present the stability regions for these types of fractional differential systems. a brief comparison with the stability aspects of fractional differential systems in the sense of riemann-liouville fractional derivatives is also given.

the aim of this study was to investigate the barrier properties of cellulose nanocrystals-pvananocomposites. nanocomposite films with different filler loading levels (3, 6, 9 and 12% by wt) weredeveloped by solvent casting method. the effect of cellulose nanocrystals on the barrier properties ofthe nanocomposites was studied. to this end, moisture absorption, water vapor permeability (wvp),oxyg...

Water-insoluble enzyme derivatives possessing specific catalytic activity may provide a useful tool in biochemical studies, since they can readily be removed from the reaction mixture and can be used for the preparation of columns with enzymatic activity. The conversion of several enzymes into the corresponding water-insoluble derivatives by their binding via covalent bonds to insoluble carrier...

The cationic functionalisation of cellulose is of considerable industrial importance and has found applications in the paper industry, cosmetics, textiles, in flotation and flocculation and in drilling fluids. In particular, it is used in the removal of acidic dyes from aqueous effluent produced by the textile industry, which significantly reduces the environmental impact of such processes. The...
