Macromolecular Rapid Communications, EarlyView.Polyesters with inherent pH‐sensitivity are prepared through radical ring‐opening polymerization between cyclic ketene acetals. These polyesters demonstrate great potential as alternatives to conventional polycations for fabricating hybrid nanoparticles.

Multi‐Solvent Suppression Ultrafast 2D COSY for High‐Throughput Wine Screening
Magnetic Resonance in Chemistry, EarlyView.An interleaved ultrafast COSY with multi‐solvent suppression was developed for wine analysis to overcome limitations often associated with 1D 1H NMR (signal overlap) and conventional 2D NMR (long acquisition times) methods. Within an acquisition time of ~20 min, it revealed hidden metabolite peaks and cross peaks for improved annotation and ...

The effects of seasonality and parasitism on diet and habitat selection in the common periwinkle
Oikos, EarlyView.The common periwinkle Littorina littorea is an ecologically important grazer, known for its strong influence on algal communities and its role in structuring ecosystems. It serves as the first intermediate host for several trematode species in the Baltic Sea, especially for the fluke Cryptocotyle lingua.

ChemistryOpen, EarlyView.The study demonstrated that thidiazine compounds potentiated the action of antibiotics. The compounds associated with norfloxacin against S. aureus showed greater significance in relation to the other medications. The indiscriminate use of antibiotics has led to the selection of resistant bacterial strains, significantly reducing the effectiveness of ...

ChemistryOpen, EarlyView.This study optimized solvent‐free geranyl benzoate production using Lipozyme 435, achieving 72% conversion in 6 hours. Open reactors improved yields (>99% in 48 hours) by removing inhibitorymethanol. Methyl benzoate reduced enzyme activity by 54%, though Lipura Flex showed better resistance. Human cell tests confirmed no cytotoxicity.

Cyanoacetamidobetaine—A Zwitterionic Nitrile Derivative
ChemistryOpen, EarlyView.The reaction of sodium dicyanamide with betainium chloride in aqueous solution affords N‐cyano‐2‐(trimethylammonio)acetaminide (cyanoacetamidobetaine). Single crystal X‐ray diffraction reveals a monoclinic structure comprising a trimethylammonium head group connected to a cyanoacetaminide unit via a methylene bridge.
