Several forms of nanocellulose, notably cellulose nanocrystals and nanofibrillated cellulose, exhibit attractive property matrices and are potentially useful for a large number of industrial applications. These include the paper and cardboard industry, use as reinforcing filler in polymer composites, basis for low-density foams, additive in adhesives and paints, as well as a wide variety of foo...

Cellulose nanocrystals (CNCs) can be obtained from bamboo pulp by hydrolysis with sulfuric acid. Firstly, the authors conducted a series of experiments under different conditions, and concluded that the optimal parameters were as follows: sulfuric acid concentration 60%, temperature 45 °C, the time is 90 minutes and the solid-liquid ratio is 1:8. Then, transmission electron microscopy (TEM), Fo...

The adsorption efficiency of gelatin-cellulose nanocrystals hydrogel membrane (GCHM) for the removal Cu(II) and Co(II) from aqueous solution was studied in batch experiments. interactive effect independent variables such as pH, contact time, temperature, ratio gelatin cellulose on were investigated. Analysis variance (ANOVA) showed that response surface quadratic model is highly impressive can ...

Cardiomyocyte Monitoring In article number 2202235, Chunyu Chang, Donghui Zhang, and co-workers develop micropatterned hydrogels with anisotropic structural colors by locking shear-oriented tunicate cellulose nanocrystals (TCNCs) in hydrogel networks through situ polymerization. The autonomous beating of cardiomyocytes drives synchronous deformations the hydrogels, causing periodic changes tran...

This communication describes a facile and mild chemical etching method for resizing of CdTe nanocrystals, which provides a possible approach for tailoring the size-dependent properties of the nanocrystals.

A simple protocol was used to prepare amine functionalized cellulose nanocrystals (CNC-NH2). In the first step, epichlorohydrin (EPH) was reacted with ammonium hydroxide to produce 2-hydroxy-3-chloro propylamine (HCPA). In the next step, HCPA was grafted to CNC using the etherification reaction in an organic solution media. Various reaction parameters, such as time, temperature, and reactant mo...

Understanding the effect on the materials mechanical properties from the perspective of interfacial interaction between the filler and the polymer matrix has become an important criterion in polymer nanocomposites field. Cellulose nanocrystals (CNCs) are renewable materials that can be extracted from natural sources, such as wood, cotton, and tunicates. In addition, CNCs have the characteristic...

Adherence and survival of pathogenic bacteria on surfaces leading to concomitant transmission to new hosts significantly contributes to the proliferation of pathogens, which in turn considerably increases the threat to human health, particularly by antibiotic-resistant bacteria. Consequently, more research into effective surface disinfection and alternative materials (fabrics, plastics, or coat...

Cellulose nanocrystals (CNCs) are high aspect ratio nanomaterials readily obtained from cellulose microfibrils via strong acid hydrolysis. They feature unique properties stemming from their surface chemistry, their crystallinity, and their three-dimensional structure. CNCs have been exploited in a number of applica‐ tions such as optically active coatings, nanocomposite materials, or aerogels. ...
