General description

1,4-二恶烷被广泛用作工业中各种有机化合物的溶剂。它是在工业废水中发现的一种不可生物降解的污染物。它通过使用氧气和臭氧而进行的氧化降解已用于将其转化为可生物降解的产物，并可通过常规方法而被容易地去除。

It remains a challenge to synthesize functional materials that can develop advanced scaffolding architectures for tissue engineering. In this study, a series of biodegradable amphiphilic poly(hydroxyalkyl (meth)acrylate)-graft-poly(l-lactic acid) (PHAA-g-PLLA) copolymers have been synthesized and fabricated into nano-fibrous scaffolds. These copolymers
