This study evaluates acetylcholinesterase (AChE) enzyme activity levels, oxidative stress parameters, histopathological findings, and serum melatonin levels in rat brain tissue. 32 male Wistar Albino rats were randomly divided into four groups: Control, Light, Dark, Dim light ( = 8 each group). After a 30 day experiment, brain tissues were collected to measure AChE, glutathione S-transferase (GST), glutathione (GSH), and malondialdehyde (MDA) levels and conduct histopathological analyses.

Solar Evaporator with Dual Gradient Heating Effect for Sustained and Efficient Desalination.

Small

January 2025

College of Polymer Science and Engineering, State Key Laboratory of Polymer Materials Engineering, Sichuan University, Chengdu, 610065, China.

Solar desalination shows promise in tackling freshwater shortages, but challenges arise from the trade-off between water transportation and heat supply, affecting evaporators' efficiency and salt resistance. Additionally, intermittent nature of solar radiation significantly diminishes overall evaporative performance. This study presents dual-gradient heating solar evaporator for efficient desalination.
