Biomass derived hierarchically porous carbon inherent structure as an effective metal free cathode for Li‐O2/air battery

Electrochemical Science Advances, 2021
A hierarchical porous carbon framework derived from betel‐nut is synthesized and employed as a bifunctional cathode in a Li‐O2/air battery. The prepared betel nut derived activated porous carbon (BNAPC) material exhibits an ordered and merged tube‐like ...

Identifying and characterising a plant GH1 β‐glucosidase that exhibits hydrolytic activity on N‐linked glucopyranoside

FEBS Open Bio, EarlyView.
We report the first β‐glucosidase with demonstrated hydrolytic activity on an N‐linked glycopyranoside. The enzyme, native to maize, was biochemically characterised for this novel reaction, and structural modelling of the enzyme–substrate complex revealed several clues to the underlying reduced catalytic rate relative to its native O‐glycopyranoside ...
