Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

Gradient p‐p Orbital Hybridization in Bismuth‐Doped Crystalline Carbon Nitride for Dual‐Functional Carbon‐to‐Carbon Valorization

open access: yesEcoEnergy, EarlyView.
Schematic illustration comparing the charge transfer dynamics and catalytic reaction over the (left) pristine carbon nitride and (right) Bi‐doped carbon nitride photocatalysts. In the pristine system, random charge diffusion and rapid recombination limit catalytic efficiency. In contrast, the Bi‐doped system establishes a robust internal electric field
