Article Abstract
Scaling presents a major challenge in water treatment industries, reducing operational efficiency and shortening the service life of membranes and plumbing systems. Frequent membrane replacement imposes a substantial economic burden. Traditional scale removal methods, including physical cleaning and chemical treatments, often cause membrane damage, environmental hazards, and additional costs. To address these challenges, this study developed an antideposition, self-cleaning membrane structure for combating scaling in water treatment. The membrane features a poly(-isopropylacrylamide) coating grafted onto carbon nanotube surfaces, providing dual functionalities: temperature responsiveness and high conductivity. These properties enable polymer motion and bubble generation on the membrane surface upon application of electrical current. The polymer movement effectively reduces deposition during operation, while the bubbles generated during water splitting reactions act as a natural cleaning mechanism. This approach offers a sustainable and efficient solution to scaling issues in water treatment systems.

Background: Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease characterized by oxidative stress and progressive motor neuron degeneration. This study evaluates the potential neuroprotective effects of caffeine in the Wobbler mouse, an established model of ALS.
Methods: Wobbler mice received caffeine supplementation (60 mg/kg/day) via drinking water, and key parameters, including muscle strength, NAD metabolism, oxidative stress, and motor neuron morphology, were assessed at critical disease stages.

Synthetic dyes, such as Congo red (CR), pose serious threats to human health and aquatic ecosystems because of their carcinogenicity and resistance to degradation, necessitating the development of efficient and eco-friendly remediation strategies. In this study, silver nanoparticles (AgNPs) were synthesized via a green method using Ocimum sanctum (holy basil) leaf extract and applied for CR dye removal from aqueous solutions. The adsorption process was optimized using response surface methodology (RSM) based on Box-Behnken design (BBD), evaluating the influence of key parameters including pH, AgNP dosage, initial dye concentration, contact time, and temperature.

A multi-indicator framework was developed to resolve multi-source pollution in highly urbanized rivers, demonstrated in the Qinhuai River Basin, Nanjing, China. Water quality index (WQI) stratification was integrated with dissolved organic matter (DOM) fluorescence components, hydrochemical ions, and conventional parameters and analyzed using positive matrix factorization (PMF). Correlation analysis further elucidated source compositions and interactions.

Background: Microfocused ultrasound (MFU) is a non-invasive technique used for facial rejuvenation, yet there is limited quantitative data on its long-term effects. This study aimed to evaluate the long-term efficacy and safety of MFU for facial rejuvenation. We utilized standardized photography along with advanced skin assessment technologies to analyze the impact of MFU on facial morphology, skin function, and patient satisfaction over a 12-month period.

How terrestrial mean annual temperature (MAT) evolved throughout the past 2 million years (Myr) remains elusive, limiting our understanding of the patterns, mechanisms, and impacts of past temperature changes. Here we report a ~2-Myr terrestrial MAT record based on fossil microbial lipids preserved in the Heqing paleolake, East Asia. The increased amplitude and periodicity shift of glacial-interglacial changes in our record align with those in sea surface temperature (SST) records.
