Direct Mechanoorganocatalysis via Surface Functionalization of Milling Reactors With Amine Functions

ChemistryEurope, Volume 4, Issue 5, May 2026.
Surface functionalization of milling jars in epoxy resin furnished reactive milling jars, able to perform direct mechanoorganocatalysis with high efficiency, recyclability, and simplified purification. This proof of concept was applied successfully to base‐catalyzed Knoevenagel condensation and multicomponent reactions.

Beyond the Solid Solution: Ordered Enantiomerically Unbalanced Packing in Surface‐Confined Tetrahelicene Monolayers

Chirality, Volume 38, Issue 5, May 2026.
Racemic dicyanotetrahelicene exhibits coverage‐dependent self‐assembly on Ag(111), transitioning from spontaneous chiral resolution at low coverage to a dense mixed phase at monolayer saturation. While submonolayer deposition produces extended homochiral domains, full coverage yields a compact, long‐range ordered lattice with an enantiomerically ...

Eco‐Friendly and Economical Approach for Immobilization of Thermostable ω‐Transaminase

Chemistry–Methods, Volume 6, Issue 5, May 2026.
This work presents immobilization of thermostable ω‐Transaminase on diatomaceous earth using eco‐friendly Fe3+‐tannic acid complexes. The immobilized enzyme retains optimal activity and preserves over half its activity after repeated cycles, offering a simple, economical immobilization strategy for industrial biocatalysis.
