Summary: This study successfully synthesized Ge/PVA/Mg(OH)(2) nanocomposites and demonstrated their good biocompatibility, ability to inhibit Aβ protein expression, and protect neuronal cells from damage. Animal experiments also showed that this nanocomposite has a protective effect on cognitive and synaptic impairments in an AD model. Therefore, Ge/PVA/Mg(OH)(2) nanocomposite may be a potential candidate for treating AD.

Summary: Polyurethane (PU) is a widely used polymer coating with favorable characteristics such as low density, nontoxicity, nonflammability, longevity, adhesion, simplicity in manufacture, flexibility, and hardness. However, it has limitations in mechanical properties, thermal and chemical stability, especially at high temperatures, where it becomes flammable and loses adhesion ability. In this study, PU composites were developed by adding reinforcements such as magnesium hydroxide and silica nanoparticles to overcome these weaknesses. The hydrophobic, physical, and mechanical properties of the pure PU and its composites were examined, and the presence of fillers was found to improve the surface topography and mechanical properties of the hybrid composite. The hybrid polymer coatings also exhibited superhydrophobic properties.

Summary: In this study, MHPA was added to HDPE to prepare flame-retardant HDPE composites, aiming to reduce smoke and toxic gases produced during combustion. The results showed that the addition of MHPA and MH improved the flame retardancy and smoke suppression of HDPE. The LOI of HDPE/MHPA/MH increased, and the pHRR, THR, and TSP values decreased compared to pure HDPE. Moreover, the HDPE/MHPA/MH composites exhibited significant mechanical properties due to the interface compatibility of bio-based MHPA.

Summary: Plastic microbeads have been produced in large quantities for cosmetics and personal care products, causing pollution in the oceans. This study investigated the biodegradability of different polymers and found that PHBV, PCL, rice, and apricot microbeads were biodegradable under seawater conditions, while PE, PMMA, and PLA microbeads were not. The results suggest that biodegradable substitutes could be used to reduce pollution by microplastics in the oceans.

Summary: In this study, a magnetic core-shell rhamnolipid (MCSR) intercalated cobalt/aluminum layered double hydroxide (LDH) was used for water remediation and rifampin (RIF) removal. The biosurfactants, including rhamnolipid (RL), demonstrated low toxicity and environmental compatibility, and promoted the removal efficiency of the adsorbent. The adsorption process was optimized by considering factors such as pH, initial RIF concentration, contact time, and adsorbent dosage. The RIF removal efficiency was found to be 96%, with a maximum adsorption capacity of 221.30 mg/g. The magnetic property of MCSR-LDH allowed for easy recovery and regeneration of the adsorbent.

Summary: The preference for farm mechanization and industrialization has led to an increase in agro-industrial waste generation, posing challenges in managing and finding sustainable solutions for these wastes. Current practices of disposing waste into water bodies and landfills contribute to environmental pollution. Agro-based materials offer potential for renewable, biodegradable, and sustainable packaging alternatives to replace petrochemical-based plastics in the packaging industry.

Summary: The study compared the efficacy of microwave-assisted extraction (MAE) and a combination of ultrasound and MAE (UMAE) in extracting mango kernel oil (MKO), and analyzed the physicochemical properties and fatty acid composition of the extracted oil. Both MAE and UMAE resulted in high oil recovery rates, with UMAE being more efficient. The fatty acid profile of MKO showed stearic acid as the dominant fatty acid, indicating its industrial potential as a cost-effective raw material for commercial mango kernel oil production.

Summary: The need for safe and healthy foods has led to the adoption of novel non-thermal food processing technologies such as cold plasma. Cold plasma utilizes charged, highly reactive gaseous molecules to inactivate bacteria on foods and packing materials. Due to its non-thermal characteristics, cold plasma does not significantly affect the chemical, physical, sensory, and nutritional properties of food items. It has a wide range of applications in the food industry and offers a safe and environmentally friendly alternative for food processing.
