This investigation reports the first application of admicellar polymerization to cellulose nanofibers in the form of bacterial cellulose, microfibrillated cellulose, and cellulose nanowhiskers using styrene and ethyl acrylate. The success of this physical sleeving was assessed by SEM, FTIR, and contact angle measurements, providing an original and simple approach to the modification of cellulos...

The dissolution of sugarcane bagasse cellulose (SBC) in zinc chloride solution was studied at elevated temperatures. Based on single factor experiments, the effects of zinc chloride mass fraction, dissolution time, temperature, and bagasse cellulose mass fraction were investigated by an orthogonal experiment, and the optimal dissolution conditions were obtained. The dissolution process of bagas...

Cellulose, a linear polymer of glucopyranose sugar molecules, is synthesized both by plants and bacteria. The plant-produced cellulose is present along with other compounds such as hemicelluloses and lignin, and has been used historically for a wide variety of applications ranging from paper-making to cosmetics. The cellulose produced by bacteria, on the other hand, is pure and difficult to mak...

Correspondence to: Shuai Zhang email: [email protected] ABSTRACT LiOH/urea/thiourea aqueous systems have been successfully applied to the dissolution of bacterial cellulose (BC) and alginate (AL) to prepare blend fibers. Morphology, compatibility and mechanical properties of the blend fibers were investigated by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT...

The objective of this research was to evaluate the potential for separating α-lactalbumin from pasteurized milk by using tangential flow membrane filtration. Filtration was carried out with a Purosep 7000 series membrane filtration unit (SmartFlow Technologies) with a regenerated cellulose membrane at 26°C and a transmembrane pressure of 186 kPa. The protein in the permeate was >80% α-lactalbum...

This review summarizes the recent advances in preparing cellulose hydrogels via ionic liquid-based processes and applications of regenerated hydrogels/iongels electrochemical materials, separation membranes, 3D printing bioinks. Cellulose is most abundant natural polymer, which has attracted great attention due to demand for eco-friendly sustainable materials. The sustainability products also d...

A small number of medicaments are used in oral and maxillofacial surgery to dress wounds, relieve pain, prevent infection and promote healing. While these materials are routinely used, their constituents, uses and effects on oral tissues are rarely discussed. This literature review provides an overview of the constituents, uses and effects of the common materials--oxidised regenerated cellulose...

Developing sustainable, low viscous and efficient solvents are always advantageous to the processing/fabricating of cellulose materials in practical applications. To this end, in this work novel solvents were developed; ([Amim][CH3COO]/PEG) by dissolving polyethylene glycol 200 (PEG-200) in 1-allyl-3-methylimidazolium acetate ([Amim][CH3COO]). The solubilities of cellulose in [Amim][CH3COO]/PEG...

Organic matter decomposition in the globally widespread coniferous forests has an important role in the carbon cycle, and cellulose decomposition is especially important in this respect because cellulose is the most abundant polysaccharide in plant litter. Cellulose decomposition was 10 times faster in the fungi-dominated litter of Picea abies forest than in the bacteria-dominated soil. In the ...
