Polymer matrix composites are popular for their lightweight and high strength. Poly (methyl methacrylate) (PMMA), known for its transparency, can be toughened with polyurethane (PU) to expand its applications. This study further strengthened PU-PMMA by adding carbon fiber powder from offcut fabrics (oCFP), enhancing mechanical and adhesion properties.

Nitrogen-fixing microorganisms (NFMs) are important components of soil N sinks and are influenced by multiple environmental factors. We established a random forest model optimized by the distributed delayed particle swarm optimization (RODDPSO) algorithm to analyze the global NFM data. Soil pH, organic carbon (OC), mean annual precipitation (MAP), altitude, and total phosphorus (TP) are factors with contributions greater than 10% to NFMs.

Alzheimer's disease (AD) is characterized by progressive cognitive decline due to neuronal damage and impaired neurogenesis. Preserving neuronal integrity and stimulating neurogenesis are promising therapeutic strategies to combat AD-related cognitive dysfunction. In this study, we synthesized metformin carbon dots (CMCDs) using a hydrothermal method with metformin hydrochloride and citric acid as precursors.

An on-site, sensitive, and cost-effective method for determining aflatoxin B1 (AFB1) in rice samples is proposed, combining magnetic solid phase extraction (MSPE) and time-resolved fluorescence immunochromatography (TRFICA) techniques. Cost-effective rice husks were carbonized and combined with nanomaterials to make magnetic nanocomposites that acted as effective adsorbents in MSPE. Under optimal conditions, the entire process was completed in 15 min with a visual detection limit of 0.
