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

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.

Review Article: The Impact of the Gut Microbiome on Ulcerative Colitis Pharmacotherapy

Alimentary Pharmacology &Therapeutics, Volume 64, Issue 6, Page 729-747, September 2026.
The gut microbiome modulates ulcerative colitis pharmacotherapy through microbial drug metabolism, immune regulation and altered drug bioavailability. Microbial composition influences response to aminosalicylates, corticosteroids, immunomodulators, biologics and small molecules, while microbiome‐targeted therapies show emerging promise.

Photogenerated Oxetanes as a Gateway to Uphill Cyclopropanation

Angewandte Chemie International Edition, Volume 65, Issue 35, 24 August 2026.
An atom‐economical route to densely functionalized cyclopropanes from furans and photochemically activated aldehydes is enabled by a unique oxetane‐to‐cyclopropane rearrangement. These cyclopropanes can be used to access complex bioactive scaffolds and serve as a platform for asymmetric cyclopropane synthesis.
