3 days ago · This study aims to analyse the potential of a two-step stir casting technique in producing Al6061/nano-SiO2 composites to enhance wear resistance in dry sliding conditions. This approach then aims to enhance the dispersion of the nano-SiO2 reinforcements to achieve enhanced anti-wear performance. Using the L27 orthogonal array, wear behaviour influenced by the different loads (5 N, 10 N and 15 N) has been investigated. For microstructural characterisation of the composite, scanning electron ...

3 days ago · Additionally, cells exposed to X-ray radiation in the presence of nanoparticles exhibit significantly decrease survival rates, which clearly depend on the concentration. Cellular survival in the presence of nanoparticles at concentrations of 25 μg/mL, 75 μg/mL, and 100 μg/mL, and under X-ray radiation (Gy6), is lower compared to the non-radiated group and indicates higher cellular cytotoxicity.
3 days ago · HMGB1 has been reported to be associated with gastrointestinal and lung injury after X-ray irradiation via the HMGB1/TLR4 signaling pathway. 42, 43 Extracellular RNA has been shown to exacerbate radiation-induced gastrointestinal injury. 44 CIRP is an RNA chaperone that normally operates in the nucleus to regulate gene expression. 45 Under stress conditions, CIRP translocates from the nucleus to the cytoplasm and is subsequently released into the extracellular space. 46 Once released ...

4 days ago · Postconsumer plastics are generally perceived as valueless with only a small portion of plastic waste being closed-loop recycled into similar products while most of them are discarded in landfills. Depositing plastic waste in landfills not only harms the environment but also signifies a substantial economic loss. Alternatively, constructing value-added chemical feedstocks via mining the waste-derived intermediate species as a carbon (C) source under mild electrochemical conditions is a ...
