新型杂化纳米材料的合成及其催化和生物应用
发布时间：2023-05-14 19:53
有机污染物造成的水污染是人类和环境生态系统的严重问题。化妆品、纺织、塑料、造纸、食品加工等多个工厂使用大量的染料。由于染料不可生物降解的性质,染料向水圈(河流、湖泊、海洋等)的排放给人类社会带来了许多挑战。此外,非常低浓度的染料(<1 mg/L)对水体生态的影响也是显著的。同样,医院中与医疗保健相关的感染对医疗保健系统造成严重的经济后果。大多数诺氏菌感染是由耐药或耐多药细菌产生的,如大肠杆菌、金黄色葡萄球菌和β溶血性链球菌。新型抗菌材料的设计是制定控制医疗相关感染新战略的最重要挑战之一。此外,还特别关注抗氧化活性高的天然物质。事实上,由多种因素弓起的氧化应激是许多病理状况产生的主要原因,如炎症、癌症、冠心病甚至皮肤老化。为了克服所有这些问题,设计新材料已成为研究人员应对现实世界中迫切需要的一大挑战。为了达到这一目标,人们非常重视开发新的路线,以设计和合成具有理想性能的材料。因此,研究者已作出努力,以最低的生产成本研制多种卓越的功能化新复合材料。本论文研究致力于研究构建新型高效、优异稳定性和可重复使用性的杂化复合材料,并开展多种应用研究。以下是本文研究的内容:1、本文报道了一种使用...
