Stable Long‐Term Cycling of Room‐Temperature Sodium‐Sulfur Batteries Based on Non‐Complex Sulfurised Polyacrylonitrile Cathodes

open access: yesBatteries &Supercaps, EarlyView.
Sulfurised polyacrylonitrile (SPAN) has been synthesized using a simple and scalable method, achieving a high sulfur content covalently linked to its framework. The development of SPAN cathodes demonstrates significant improvements in combating capacity fading and the shuttle effect in sodium‐sulfur (Na−S) batteries.

Designing Enzymatic Reactivity with an Expanded Palette

open access: yesChemBioChem, EarlyView.
Innovation in biocatalysis is rapidly increasingly the diversity of catalytic reactivity that can be mediated by enzymes, addressing a key bottleneck for their widespread adoption in industrial chemical synthesis. A key approach to this is building enzymes with unnatural catalytic components that provide an expanded palette with new possibilities for ...
