Oxidation of cellulose in pressurized carbon dioxide [PDF]
, 2009 This work presents first results upon oxidation of type II cellulose by nitrogen dioxide dissolved in carbon dioxide at high pressure. This reaction leads to oxidized cellulose, a natural-based bioresorbable fabric used for biomedical applications.

Synthesis and adsorption performance of functionalized chitosan and carboxyethylsilanetriol hybrids
BMC Chemistry, 2023 A novel adsorbent from cationic chitosan derivative and anionic silica precursor was fabricated to remove methylene blue (MB). The hybrid material was prepared from N-guanidinium chitosan acetate (GChi) and carboxyethylsilanetriol sodium salt by a simple

Anion specific adsorption of carboxymethyl cellulose on cellulose
Langmuir, 2023 Integration of fiber modification step with modern pulp mill is a resource efficient way to produce functional fibers. Motivated by the need to integrate polymer adsorption with the current pulping system, anion-specific effects in Carboxymethylcellulose (CMC) adsorption have been studied.

Studies on the Cellulose-Binding Domains Adsorption to Cellulose [PDF]
Langmuir, 2004 Cellulose-binding domains (CBD) are modular peptides, present in many glycanases, which anchor these enzymes to the substrate. In this work, the effect of CBD adsorption on the surface properties of a model cellulose, Whatman CF11, was studied. The methods applied include inverse gas chromatography (IGC), ESCA, X-ray diffraction, and scanning electron ...

Materials, 2013 Cellulose micro/nano-fibers can be produced by electrospinning from liquid crystalline solutions. Scanning electron microscopy (SEM), as well as atomic force microscopy (AFM) and polarizing optical microscopy (POM) measurements showed that cellulose-based electrospun fibers can curl and twist, due to the presence of an off-core line defect disclination,
