Effect of Concentration of Lithium Bis(fluorosulfonyl)imide on the Performance of Silicon Anodes for Li‐Ion Batteries

open access: yesElectrochemical Science Advances, Volume 6, Issue 1, February 2026.
The rate performance of Si anodes in a 5 M lithium bis(fluorosulfonyl)imide electrolyte (molar ratio of salt to solvent of 1:2.5) is similar to the rate performance of the 1 M electrolyte. However, the solid electrolyte interphase formed in the 5 M electrolyte is less passivating, and for stable, long‐term cycling, limiting the lithiation is necessary.

Evaluation of Banana Pseudostem Fibres for Packaging Material Development

open access: yesPackaging Technology and Science, Volume 39, Issue 1, Page 91-103, January 2026.
Composites were developed from banana pseudostem fibres, extracted from a thermomechanical method to produce pulp, which was subsequently hot‐pressed with gum arabic to form fibreboards intended as sustainable packaging material. ABSTRACT The present study investigated composites prepared from banana pseudostem fibres (BF) and gum arabic (GA), in ...

Tailoring a 3D Covalent Organic Framework Toward Facile Functionalization

open access: yesSmall, Volume 22, Issue 3, 13 January 2026.
Nucleophilic groups are installed onto the linkages of the well‐known covalent organic framework, COF‐300, which allows for the synthesis of eight new COF‐300 derivatives. The structure of the amine‐appended framework COF‐300‐NH2 is solved using microED, and this material exhibits significantly improved adsorption capacity for CO2 and perfluoroalkyl ...
