Article Abstract
The latest research shows that algal biofuels, at the production levels mandated in the Energy Independence and Security Act of 2007, will place significant demands on water and compete with agriculture meant for food production. Thus, there is a great need to recycle water while producing algal biofuels. This study shows that when using a synthetic medium, soluble algal products, bacteria, and other inhibitors can be removed by centrifugation and enable water recycling. Average water recovery reached 84% and water could be recycled at least 10 times without reducing algal growth.

Cesium ions (Cs) are notable radioactive contaminants hazardous to humans and the environment. Among various remediation methods, adsorption is a practical way to remove Cs from water, and Prussian blue (PB) is well-known as an efficient Cs adsorbent. Although various PB derivatives have been proposed to treat Cs-contaminated water, soil remediation is still challenging due to the limited mobility of pollutants in soil.

Corrosive sulfur compounds and trace moisture were key factors causing the rapid deterioration of finished mineral oils. In power systems, insulating oil contaminated by such substances not only threatens the stable operation of power equipment but also transforms into hazardous waste due to performance degradation. This study innovatively developed a sulfur-modified TiO-loaded SiO nanocomposite (S-nTDSGS) adsorbent, which was comprehensively characterized by scanning electron microscopy, X-ray photoelectron spectroscopy, and specific surface area analysis.

Two-dimensional (2D) nanofluidic architectures with nanoconfined interlayer channels and excess surface charges have revolutionized membrane-based reverse electrodialysis systems, demonstrating highly efficient osmotic energy collection through strong electrostatic screening of electric double layer (EDL). However, the ion-transport dynamics in 2D nanofluidic anion-selective membranes (2D-NAMs) still remain unexplored. Here, we combine density functional theory and molecular dynamics (MD) simulations to systematically explore ion transport in the 2D-NAMs.

The degradation of colorless tetracycline hydrochloride (TCH), a widely used antibiotic, is a significant environmental concern due to its persistence in aquatic systems. The zinc sulfide (ZnS) nanoparticle fabricated melamine-formaldehyde polymer (MFP)-based nanocomposite (ZnS-MFP) was prepared via a hydrothermal polymerization method, followed by surface modification through a simple precipitation route. The degradation of TCH through photocatalysis adheres to pseudo-first-order kinetics with a significantly faster rate under natural sunlight than under artificial bulb light.

Introduction: The development of new drugs for Alzheimer's disease (AD) remains a major challenge due to the disorder's complex and multifactorial nature. 2'-Fucosyllactose (2'-FL), a human milk oligosaccharide, has demonstrated promising neuroprotective properties. However, its effects on AD-related cognitive decline are not yet fully understood.
