Sustainable Graphene Oxide–Intercalated Bentonite Composite for the Effective Removal of Imidacloprid From Water: Adsorption Performance, Isotherm, and Kinetics

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Water is a fundamental necessity for our existence, but its rapid contamination is causing devastating effects on the environment and health of living species worldwide. Adsorptive removal of pollutants is one of the popular water treatment techniques because of its simplicity, affordability, and the broad range of available adsorbents.

Perfluorooctane sulfonate mediates GSH degradation leading to oral keratinocytes ferroptosis and mucositis through activation of the ER stress-ATF4-CHAC1 axis

Ecotoxicology and Environmental Safety
Perfluorooctane sulfonate (PFOS) is a persistent organic pollutant that induces inflammatory response and oxidative stress in oral mucosa. Ferroptosis, a form of cell death characterized by iron-dependent lipid peroxidation (the oxidative degradation of ...

Synthesis and Application of Conductive Pitch‐Based Porous Carbon for Energy Storage Device as a Supercapacitor

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Conductive pitch‐based porous carbon materials were synthesized and systematically investigated as high‐performance electrode materials for supercapacitors. Petroleum‐derived pitch was thermally treated and chemically activated using KOH and NaOH at different pitch: activating agent molar ratio (1:1, 1:2, and 1:4) to optimize the pore ...
