• Separation of Caustic Nano-Emulsions and Macromolecular Conformations with Nanofibrous Membranes of Marine Chitin. Z Wang, J Xu, M Li, C Su, X Wu, Y Zhang, J You, C Li, ACS Appl. Mater. Interfaces  2019, 11, 8576−8583
    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有机溶剂中分离纳米乳液、纳米颗粒和刚性大分子并取得了较好的效果。因此,这种低成本、可持续发展的滤膜可能会在纳米乳液分离、浓缩纳米颗粒、废水处......

  • Inhibiting and catalysing amyloid fibrillation at dynamic lipid interfaces Xiangsheng Han, Xiaochen Wu, Lili Lv, Chaoxu Li, Journal of colloid and interface science, 2019, 543, 256-262
    自然界中,蛋白质通常会接触各种界面,例如固态界面和动态界面。固态界面可富集蛋白质分子,进而催化、延缓或抑制淀粉样纤维化过程。然而,生态系统中普遍存在的动态界面对蛋白质淀粉样纤维化过程的影响研究相对匮乏。不饱和脂肪酸在饮食中具有重要作用,在一定的生理环境下可在体外催化蛋白质淀粉样纤维化。该过程得益于不饱和脂肪酸烷基链中双键的位置以及外加的剪切力。DHA由于特殊的分子结构,不利于蛋白质cross-β成核,因此无法催化蛋白质淀粉样纤维化。将不同脂肪酸混合后可延缓蛋白质淀粉样纤维化过程。脂肪酸对蛋白质纤维化过程的高催化活性提供了新的生物基纳米纤维制备途径,并......

    Liquid metal (LM) droplets show the superiority in coalescing into integral liquid conductors applicable in flexible and deformable electronics. However, the large surface tension, oxide shells and poor compatibility with most other materials may prevent spontaneous coalescence of LM droplets and/or hybridisa......

    Porous metal foams have been one of the most sought-after materials owing to their combination of bulk metallic characteristics (e.g., thermal/electrical conductivity and ductility) and nanometric size-effect properties (e.g., catalytic reactivity, plasmonic behavior, and high surface area). Traditional sol-gel appr......
