The commercial viability of microalgal biorefineries is currently constrained by high energy demands during pretreatment and incomplete biomass valorization arising from cell wall recalcitrance. To overcome these challenges, this study developed a high-efficiency simultaneous saccharification and fermentation (SSF) strategy using an immobilized tri-enzyme ...

This study evaluates a mixed-culture microbial fuel cell (MFC) as a rapid, real-time biosensor for detecting water toxicity caused by heavy metals and benzene, toluene, ethylbenzene, and xylene (BTEX) compounds. A dual-chamber MFC (200 mL) equipped with carbon fiber electrodes was operated with an electroactive biofilm on the anode, and toxicity responses ...

Artificial intelligence (AI) and machine learning (ML) are increasingly integrated into Per- and polyfluoroalkyl substances (PFAS) research; however, the field remains fragmented with substantial variation in modeling objectives. This review provides one of the most comprehensive and detailed syntheses to date of AI/ML methods across the PFAS contaminatio ...

This study investigates the thermochemical and co-thermochemical conversion of black mass (BM), derived from spent lithium-ion batteries, with and without polyethylene (PE) under various atmospheric conditions (N2, 25 % CO2, and 99.999 % CO2) at temperatures ranging from 700 °C to 900 °C. In an inert N2 environment, gas emissions were minimal, while signi ...

Per- and polyfluoroalkyl substances (PFAS) are highly persistent synthetic chemicals that pose severe environmental and health risks, prompting increasingly stringent regulations. The recent crises caused by PFAS contamination underscore the urgent need for rapid, sensitive, and on-site monitoring, along with effective removal and degradation from water s ...

Per- and polyfluoroalkyl substances (PFAS), such as perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), are persistent environmental pollutants posing significant risks to ecosystems, drinking water safety, and human health. Conventional PFAS removal methods effectively mitigate contamination but face challenges such as high operational ...

Recent advancements in membrane technologies and disinfection methods have enhanced drinking water quality significantly. However, microorganisms, including free-living amoebae (FLA), persist and pose potential threats to humans. FLA are linked to severe neuro-ophthalmic infections and serve as h ...
