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

ChemSusChem, 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 ...

Synthesis and Biological Profile of Substituted Pyrrolidinyl Carboxamides for Acyl‐ACP Thioesterase Inhibition

European Journal of Organic Chemistry, EarlyView.
The work outlined herein covers a series of novel herbicidal lead structures that possess a pyrrolidinyl pyrazole carboxamide scaffold as a key structural feature, carrying further substituted benzyl side chains. Based on scaffold hopping approaches from known fungicidal and herbicidal compounds and utilizing an optimized synthetic approach, a broader ...

Multifunctional ionic liquid boosts the efficiency of hole transport layer‐free carbon‐based perovskite solar cells beyond 20%

FlexMat, EarlyView.
HTL‐free carbon‐based PSCs are promising in stability but limited by efficiency. Systematic screening identifies DMAFo as an optimized ionic‐liquid additive: the DMA+ regulates lattice distortion and relieves residual stress, while Fo‒ passivates halide vacancies, and ameliorates band‐alignment.

Leveraging Diamines to Unlock the Mn‐MACHO Catalyst in the Reduction of CO2 to Methanol

Angewandte Chemie, Volume 138, Issue 10, 2 March 2026.
CO2 hydrogenation to methanol using a Mn–MACHO catalyst was achieved without Lewis acid promoters, delivering TONs up to 45.2. Diamines, by driving a highly exergonic double amidation reaction, divert formate resting states toward the active catalyst. The correlation between ΔGamidation and methanol productivity enables the rational design of the amine
