Performance of commercial polyamide membranes in pervaporation for dye removal: Impact of dye classes, colors, and surfactants

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 9, Page 1742-1756, September 2026.
Abstract BACKGROUND Water reclamation in the textile industry is essential to reduce environmental impacts associated with high water consumption and pollutant discharge. Among emerging technologies, pervaporation (PV) has gained attention due to its high selectivity and efficiency in contaminant removal. However, there is still a lack of comprehensive

Unlocking a Nitrosuccinate Lyase for Decarboxylative Enzymatic Hydronitration

Angewandte Chemie, Volume 138, Issue 31, 27 July 2026.
The nitrosuccinate lyase CreD catalyzes C–NO2 bond formation using nitrite in water and shows synthetic practicality with high turnover numbers up to 102,000. A combination of protein engineering and computational methods helped to reveal the mechanistic principles that underpin this unique enzymatic activity.

A Physical Organic Odyssey: From the Ultrafast Dynamics of Carbenes and Nitrenes to Contemporary Chemical Biology and Drug Discovery

Journal of Physical Organic Chemistry, Volume 39, Issue 9, September 2026.
Physical organic chemistry transforms photoaffinity labeling from empirical photochemistry into rational probe design. By measuring reactive‐intermediate lifetimes, pathways, and selectivity, Platz's legacy connects carbene and nitrene mechanisms to modern chemoproteomics, enabling more precise protein labeling and drug‐discovery maps.

Photochemistry of Aromatic N‐Oxides in Water Probed by Time‐Resolved X‐ray Absorption Spectroscopy

Chemistry – A European Journal, Volume 32, Issue 29, 7 August 2026.
Time‐resolved XAS at the nitrogen and oxygen K‐edges is applied to the photorearrangement of two N‐oxides in water. Pyridine N‐oxide rapidly forms the oxaziridine isomer. Pyridazine N‐oxide undergoes ring opening to the diazo compound, without any evidence of intermediates.

Rhodium‐Catalyzed Carbene Transfer to Isocyanides Using Zinc Carbenoids

European Journal of Organic Chemistry, Volume 29, Issue 29, 7 August 2026.
A diazo‐free rhodium‐catalyzed carbene transfer to isocyanides using zinc carbenoids generated from α‐acyloxy halides is reported. This mild protocol furnishes ketenimines that can either be hydrolyzed to amides or intercepted with trimethylsilyl azide or carboxylic acids to give tetrazoles and imides, respectively.

Original Reactivity of ?-Diazo-?- ketoesters Catalyzed by CpRu Complexes

CHIMIA, 2014
Using ?-diazo-?-ketoesters as reagents and combinations of CpRu fragments and diimine ligands as catalysts, a series of original transformations have been obtained that can be rationalized by the formation of metal carbenes and metal-bound ylide
