A Bifunctional UiO‐66 Platform Enabled by Schiff‐Base Engineering for CO2 Conversion and Epoxide–Anhydride Copolymerization

Small, EarlyView.
Bifunctional UiO‐66‐Schiff‐base‐M(II) (M = Zn, Cu, Ni) MOF catalysts enable efficient and selective epoxide/anhydride copolymerization and CO2/epoxide coupling under mild conditions. The catalysts feature tunable Lewis acidity, high recyclability, and structural robustness, offering a sustainable platform for green polymer synthesis and carbon dioxide ...

Unraveling Pathway Complexity in Photoreversible Supramolecular Hydrogels: Real‐Time Visualization and Sub‐Micrometric Photopatterning

Small, EarlyView.
This research demonstrates real‐time visualization of supramolecular sol‐gel transitions using Fluorescence Lifetime Imaging Microscopy (FLIM). By leveraging 5D visualization, integrating 3D space, time, and polarity resolution, we achieved maskless sub‐micrometric photopatterning within the gel matrix.

Visible‐light‐promoted catalyst‐free benzylic C‐H oxidation using molecular oxygen as a green oxidant

Smart Molecules, EarlyView.
A green and simple photo‐oxygenation of benzylic C‐H bond with molecular oxygen was developed for the preparation of a series of carbonyl compounds. The straightforward C‐H carbonylation strategy features catalyst‐ and additive‐free reaction conditions, only oxygen as a green oxidant, broad scope and scalable, and the simple‐operation nature.

A covalent peptide engager approach to equip immunotherapeutic monoclonal and pan IgG serum antibodies with new tumour‐targeting function

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Site‐specific antibody modification is a useful chemical strategy to elaborate antibody therapeutic function. Conventional lysine‐ or cysteine‐based conjugation methods generate heterogeneous products, while protein engineering approaches are resource‐intensive.

Effects of non‐host traces on behavioural responses of an egg parasitoid to substrate‐borne semiochemicals in a multi‐herbivore scenario

Ecological Entomology, EarlyView.
In open arena assays, the response of the egg parasitoid Trissolcus basalis to substrate‐borne semiochemicals left by the host Nezara viridula was affected by the non‐host Spodoptera littoralis. Non‐host larval traces reduced T. basalis residence time spent on walking traces from gravid N. viridula females but did not affect responses to walking traces

Insights into tandem dioxygenases—copper radical oxidases in fungal Phytopathogens of the Colletotrichum acutatum species complex

The FEBS Journal, EarlyView.
In Colletotrichum acutatum species complex, conserved ring‐cleavage dioxygenases located adjacent to AA5_2 enzymes were investigated as potential redox partners. Biochemical analyses identified the dioxygenases as intradiol‐cleaving enzymes preferentially oxidizing methyl‐substituted catechols, while AA5_2 enzymes displayed weak alcohol oxidase ...
