Kink formation in nanocellulose: Comparing TEMPO oxidation and carboxymethylation
Carbohydrate Polymer Technologies and ApplicationsThis study investigated the kink formation mechanisms in nanocellulose induced by two typical carboxylation methods. TEMPO-mediated oxidation significantly made the nanocellulose chains more water-attracting and easier to dissolve, especially in the less

Production of Nanocellulose from Rice Husk [PDF]
Iranian Journal of Wood and Paper Industries, 2013 In this work, nanocellulose was produced from rice husk, as a lignocellulosic waste of rice. Initially, purified cellulose was produced with chemo-mechanical and soda-anthraquinone (soda/AQ) pulping and bleaching.

Advanced Science, EarlyView.We have developed a glucose‐triggered on‐demand drug delivery CF‐CPGaMPN hydrogel based on borate ester bonds. It inactivates microbes, releases oxygen, and enables on‐demand drug release in high‐glucose environments to promote healing of diabetic wounds. Single‐cell sequencing reveals that the CF‐CPGaMPN hydrogel significantly alleviates dysfunctional

Advanced Science, EarlyView.This study shows that amyloid fibrils form nematic condensates via liquid–liquid crystalline phase separation (LLCPS). With increasing pH, this transition shifts toward disordered condensates formed through liquid–liquid phase separation (LLPS), in which birefringence with lack of a coherent nematic field symmetry originates from enthalpic fibril ...

Bio‐templated Piezoresistive Yarn for High Sensitivity Movement Monitoring Textiles
Advanced Science, EarlyView.This study developed a conductive coating by biotemplating silver nanoparticles (AgNPs) onto a Potato virus A (PV) particle network, cross‐linked on co‐polyamide‐starch (CoPA‐SS) coils. The combination of CoPA‐SS's shape memory and PV‐AgNP's piezoresistivity achieved high strain sensitivity and minimal hysteresis.
