Effect of polystyrene nanoplastics on its toxicity and reproduction in Philodina roseola
2025 / Scientific ReportsMicro-nano plastics have emerged as a major ecological concern. The nanoplastics (NPs) pose a huge threat to microscopic animals. Our study aims to decipher the effect of polystyrene nanoplastics (PSNPs) of 50 and 100 nm sizes on a bdelloid rotifer (Philodina roseola). Both sizes of PSNPs were analyzed using field emission Scanning electron microscopy, Fourier tr...

Mixed matrix membrane of poly(4-methyl-1-pentyne) and ZIF-8 for enhanced CO2 separation over H2 and CH4
2025 / Scientific ReportsCarbon dioxide (CO2) generally exists as the main impurity in natural gas, whose main component is methane. The presence of CO2 reduces the energy content of natural gas and also causes the corrosion of pipelines. To prevent such problems, natural gas must contain a small concentration of CO2 (less than 2% by weight). Membrane technology is an attractive separati...

Cranberry Extract Ameliorates Diabetic Cognitive Impairment in Rats Via LncRNA GAS-5 Downregulation and Pyroptosis Pathway Inhibition
2025 / Journal of Neuroimmune PharmacologyThe pathophysiology of diabetes-induced brain injury involves pyroptosis, an inflammatory programmed cell death. This study aimed to investigate the potential protective effect of cranberry extract (CE) against diabetes-induced brain injury. Type 1 diabetes was induced by intraperitoneal injection of streptozotocin in rats. Brain tissue samples were investigated fo...

Hunter-gatherer sea voyages extended to remotest Mediterranean islands
2025 / NatureThe Maltese archipelago is a small island chain that is among the most remote in the Mediterranean. Humans were not thought to have reached and inhabited such small and isolated islands until the regional shift to Neolithic lifeways, around 7.5 thousand years ago (ka)1. In the standard view, the limited resources and ecological vulnerabilities of small islands, cou...

Self-disassembling nanoparticles as oral nanotherapeutics targeting intestinal microenvironment
2025 / Nature CommunicationsInspired by the survival strategies of pyomelanin-producing microbes, we synthesize pyomelanin nanoparticles (PMNPs) from homogentisic acid- γ-lactone via auto-oxidation and investigate their biomedical potential. PMNPs possess distinct physicochemical properties, including reactive oxygen species scavenging and microenvironment-responsive self-disassembly....

Synthesis of nickel(II)-containing meso-edited phthalocyanine derivatives
2025 / Nature CommunicationsIn contrast to the rich chemistry of porphyrin and its analogs, the structural variety of phthalocyanine derivatives, which are widely utilized in material and life sciences, has been limited by the lack of versatile synthetic methods. Herein we present a synthetic strategy/methodology for the meso-position editing of phthalocyanine derivatives via deprotonative ...

Improving Cyclability and Structural Stability of Co-Free Layered Cathode by Controlling Porosity and Cracks in Secondary Particles for Low-Cost and High-Energy LIBs
2025 / Advanced Functional MaterialsThe Co-free Li[Ni0.75Mn0.25]O2 (NM7525) cathode offers the significant advantage of low production costs. However, it requires a high-voltage charging process (≥4.5 V vs Li/Li⁺) to achieve the energy density level of high-Ni Li[NixCoyMnz]O2 (x ≥ 0.8) cathodes, which leads to severe structural and morphological degradation in the secondary particles during p...
