Spatial Structural Self‐Regulation Engineering Increases Close Pores of Starch‐Derived Hard Carbon for Sodium‐Ion Batteries

Carbon Energy, EarlyView.
Spatial structural self‐regulation strategy stimulates the conversion of the hydroxy group (–OH) in starch into carbonyl (–C=O) within a stable three‐dimensional cross‐linking structure. This structure not only reduces the production of water and volatile products, thereby preventing foaming during pyrolysis and improving carbon yield, but also ...

Characterization of microcrystalline cellulose and silicified microcrystalline cellulose wet masses using a powder rheometer

European Journal of Pharmaceutical Sciences, 2001
A powder rheometer has been used to study the properties of wet powder masses and the results have been compared to the mixer torque rheometer (MTR). Two different microcrystalline cellulose (MCC) grades (Avicel and Emcocel) and silicified microcrystalline cellulose (SMCC, Prosolv) were used as model powders.

A Simple Regeneration Process Using a CO2‐Switchable‐Polarity Solvent for Cellulose Hydrogels

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The effect of transformation of the anion chemical structure on cellulose solubility by flowing CO2 gas into aqueous pyrrolidinium hydroxide solutions was investigated. The changes in anion structure allowed for the modulation of cellulose solubility in aqueous pyrrolidinium hydroxide solutions, thus establishing a simple and safe cellulose ...
