Photothermal–Magnetocaloric Coupled Evaporators for Actively Adjustable Water Evaporation and Oil–Water Purification in Complex Environments

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A photothermal–magnetocaloric coupled aerogel evaporator is developed for actively adjustable water evaporation in complex environments. Magnetocaloric heating provides active energy compensation under low‐light conditions and disrupts interfacial hydrogen‐bond networks to promote evaporation.

Surfactant Enhanced Bioremediation of Saline Diesel Contaminated Water by a Novel Bacterial Halophilic Consortium

Journal of Surfactants and Detergents, EarlyView.
ABSTRACT The use of microorganisms is an evolving method for the degradation of hydrocarbon contaminants. In this aim, halophilic hydrocarbon degrading bacteria were isolated from oil contaminated soil in Tunisia. A lipopeptide biosurfactant produced by Bacillus subtilis SPB1 was tested to increase diesel biodegradation along with co‐inoculation with ...

Chronic, Environmentally Relevant PM2.5 Exposure Exacerbates Metabolic Dysfunction‐Associated Steatotic Liver Disease and Early‐Stage Renal Dysfunction in a Rodent Model

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT While epidemiological studies link fine particulate matter (PM2.5) exposure to metabolic dysfunction‐associated steatotic liver disease (MASLD) and renal dysfunction, a translational gap exists, as most animal models utilize acute, high‐dose exposures that poorly reflect chronic, moderate‐level human scenarios.
