Isolation of microcrystalline alpha-cellulose from jute: A suitable and economical viable resource

open access: yesGSC Biological and Pharmaceutical Sciences, 2022
Cellulose is a natural linear chain homopolymer that is an abundant and common component in all plants. Partially pure depolymerized cellulose, known as microcrystalline cellulose (MCC), is synthesized by mineral acids hydrolysis from α-cellulose precursors obtained from fibrous plants such as jute. Virgin soft and hardwoods are used as the main source

Tuning Separator Chemistry: Improving Zn Anode Compatibility via Functionalized Chitin Nanofibers

open access: yesAdvanced Functional Materials, EarlyView.
Nanochitin derived from waste shrimp shells is used to fabricate separators for aqueous zinc batteries. By tuning the density of amine and carboxylic surface groups, water mobility at the separator interface is controlled, promoting uniform zinc deposition, suppressing dendrite growth, and enabling exceptional cycling stability exceeding 2000 h ...

Swelling‐Induced Stress‐Assisted Transfer of Nanodiamond Arrays With a PVA Carrier Tape for Conformal Bio‐Integrated Sensing and Labelling

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces a swelling‐induced, stress‐assisted water‐soluble PVA tape strategy to transfer‐print nanodiamond quantum‐sensor arrays onto soft, curved biological interfaces. The room‐temperature, water‐triggered process achieves >98% fidelity and residue‐free integration, enabling conformal quantum sensing on contact lenses, neural probes, and ...
