Model films of cellulose II - Improved preparation method and characterization of the cellulose film

open access: yes, 2004
An optimization study of the preparation of spin-coated cellulose model films from the NMMO/DMSO system on silicon wafers has been made. The study shows that the cellulose concentration in the solution determines the cellulose film thickness and that the

Biosynthesis of Spatially Differentiated Cellulose for Flexible All‐in‐one Supercapacitors

open access: yesAdvanced Science, EarlyView.
Spatially differentiated bacterial cellulose is grown by oxygen‐guided biosynthesis to form dense surface regions connected by an open fibrillar interlayer. This architecture supports electroactive material loading, ion transport, and mechanical stability in an all‐in‐one supercapacitor, showing how biological assembly can create device‐ready ...

Supramolecular Zinc–Polyphenol Coordination Assemblies Mitigate Colonic Inflammation by Regulating Mucosal Barrier and Microbiome

open access: yesAdvanced Science, EarlyView.
A carrier‐free zinc‐coordinated polyphenol nanoplatform (ZnCA NPs) is designed as an “all‐in‐one” therapeutic strategy for intestinal inflammation. The ZnCA NPs exhibit enhanced colonic accumulation and broad‐spectrum reactive oxygen and nitrogen species scavenging.

Synergistic Integration of Fe–N4 Single‐Atom Sites and Directionally Aligned Electrode Architecture for High‐Performance Lithium–Sulfur Batteries

open access: yesAdvanced Science, EarlyView.
A directionally ice‐templated sulfur cathode integrated with atomically dispersed Fe–N4 catalytic sites is developed for high‐performance lithium–sulfur batteries. The structure–catalysis synergy accelerates Li+ transport and polysulfide conversion, leading to high sulfur utilization and stable long‐term cycling performance.
