Abundant and renewable all-cellulose-derived humidity sensors are fabricated via direct laser writing of patterned electrodes onto TEMPO-oxidized cellulose fiber paper, offering versatile applicability for the “trillion sensor” era.

A short review with 49 references describes the electrospinninng (ES) process for polysaccharides, cellulose and chitosan, and their derivatives, including cellulose acetate and hydroxypropyl cellulose. A majority of applied studies adopted a two step-process, in which the cellulose acetate was used for the first ES process, followed by acetyl group removal to regenerate cellulose thin fibers. ...

This study assessed the effectiveness of using an oxidized cellulose dental dressing in order to reduce the rate of alveolar osteitis after posterior tooth extraction in smokers. Dry socket incidences of heavy smokers from 4 independent dental clinics, which routinely used oxidized cellulose dental dressings to mitigate dry socket formation between March 2011 and December 2012, were compiled an...

De novo synthesis of wall material by cells of Sphaerocarpos donnellii was followed using radioactive tracer techniques. Uniform uptake of [14C]glucose by plasmolysed suspension cultures was demonstrated autoradiographically. Liquid scintillation counts of acid- or alkali-soluble wall carbohydrates indicate that hemicellulose and cellulose make up the major wall fractions in control and plasmol...

Electrochemical characterization of three cellophane membranes with different content of regenerated cellulose was carried out by determining salt diffusion and ion transport numbers, which were obtained from diffusion and membrane potential measurements carried out with the membranes in contact with NaCl solutions at different concentrations. Results show a decrease for salt permeability with ...
