Preparation and mechanical properties of modified nanocellulose/PLA composites from cassava residue

AIP Advances, 2018
Nanocellulose was prepared by a mechanochemical method using cassava residue as a raw material and phosphoric acid as the auxiliary agent. The prepared nanocellulose was hydrophobically modified with stearic acid to improve its dispersibility.

A Covalent Organic Framework With Staggered Topology for Mimetic Transmembrane Transport of Hydrated Ions

Advanced Science, EarlyView.
Inspired by biological ion channels, an AB‐staggered β‐ketoenamine‐linked COF enables rapid hydrated‐ion transport through a biomimetic dehydration‐compensation mechanism, where carbonyl‐rich convergent channels partially offset ion dehydration energy. As aqueous Zn battery separators, the COF membranes suppress parasitic reactions and dendrite growth,

Kink formation in nanocellulose: Comparing TEMPO oxidation and carboxymethylation

Carbohydrate Polymer Technologies and Applications
This 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.

Multi‐Scale Bionic Structure Constructs Biomass Flame‐Retardant Thermal Insulation Foam Material

Advanced Science, EarlyView.
Inspired by mussel adhesion and hierarchical brick‐and‐mortar architectures, a cellulose‐based biomimetic foam is constructed by anchoring bentonite nanosheets onto a polydopamine‐decorated cellulose nanofiber network. The resulting foam combines low thermal conductivity with intrinsic flame retardancy and full biodegradability, presenting a ...
