纳米技术的可持续发展受到了纳米污染物的严重挑战。生物基纳米膜分离技术是一种环保且低耗能的分离技术,但由于膜的孔径分布广、耐溶剂性差、结构不稳定等缺点限制了其广泛应用。为了避免纳米尺度的物体在腐蚀性液体或有机溶剂中的泄漏,我们尝试在不破坏化学结构和晶体结构的前提下从蟹壳中剥离甲壳素纳米纤维并制成纳米纤维滤膜,这种滤膜不但具有超强的结构稳定性、耐久性、渗透率和截留性能,而且还有厚度可控、孔径分布窄并且可调等优点。我们利用这种滤膜在腐蚀性液体或......

Marine shells not only represent a rapidly accumulating type of fishery wastes but also offer a unique sort of hybrid nanomaterials produced greenly and massively in nature. The elaborate “brick and mortar” structures of nacre e......

Living microbes can accumulate and exhibit distinct responses to different metal ions by strong coordination between bio-macromolecules and metal ions. Thus carefully selected bio-macromolecules could possibly ......
