ABSTRACT Purpose: Bacterial cellulose (BC) has shown high capacity for the treatment of wounds and burns, providing a moisty environment. Calcium alginate can be associated with BC to create gels that ...

The efficient use of cellulose—the primary plant scaffold and a major natural building block—could address many issues associated with petroleum-based polymers across various industries. In ...

Scientific American is the essential guide to the most awe-inspiring advances in science and technology, explaining how they change our understanding of the world and shape our lives.

“The cellulose gels are robust, stable at room temperature and can be tuned to degrade on a schedule, so would be useful in drug delivery applications, among others,” Lucia says.

Methylcellulose is also added, to bulk up the mixture. The resulting viscous gel can be extruded from the nozzle of an ordinary 3D printer at room temperature, building an item up one layer at a time.

RALEIGH – Researchers have developed a metallic gel that is highly electrically conductive and can be used to print three-dimensional (3D) solid objects at room temperature.

It absorbed water at room temperature and, when heated by the artificial light, released 70% of its stored water in 10 minutes — a rate four times greater than the one for a previously reported ...

Cellulose is the most abundant organic compound on Earth, and its outstanding qualities as biodegradable nature make it a perfect substitute for petroleum-based polymers. A challenge in the ...

A commercially available bovine collagen I gel with similar solid content to the TCNF/ALG precursors was used as a control (3.5% w/v, Advanced Biomatrix, United States). The collagen I gel was printed ...

In this study, these different materials were obtained from paper using different methodologies. Cellulose nanocrystals were obtained by acid hydrolyzis and neutralized (CNC-n) or oxidized (CNC-t) ...
