Co‐Acid Free Nitration of N,N‐Dimethylanilines Using Traditional and Nontraditional Activation Methods

open access: yesChemistry–Methods, Volume 6, Issue 9, September 2026.
Selective mono‐ and dinitration of dimethylanilines by co‐acid‐free dilute aqueous nitric acid using nontraditional activation methods, such as microwave, ultrasound, and high hydrostatic pressure. The nitration of aromatic compounds is a highly important transformation, contributing to the synthesis of dyes, agrochemicals, explosives, pharmaceuticals,

Channel Microenvironment‐Controlled Pillared MOF as Efficient Triboelectric Nanogenerator Material for Self‐Powered Degradation of Organic Pollutants

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
The pore microenvironment regulation of metal–organic framework (MOF) significantly enhanced the output performance of triboelectric nanogenerators (TENG) through SC‐SC transformation, which provides a new idea for the construction of self‐powered degradation systems for organic pollutants.

Synthetic Food Colorants and Gut Microbiota: A Systematic Review of Preclinical Studies

open access: yesFood Frontiers, Volume 7, Issue 5, September 2026.
ABSTRACT Growing evidence suggests that industrial food processing, including the excess consumption of food additives, might have a negative impact on human health. Despite regulatory safety evaluations, their impact on gut microbiota remains poorly characterized.

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

open access: yesJournal 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
