• 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......

  • Macroscopic Single-Crystal Gold Microflakes and Their Devices. Zhou, J., Saha, A., Adamcik, J., Hu, H., Kong, Q., Li, C., & Mezzenga, R. (2015). Advanced Materials, 27(11), 1945-1950.
    A facile, green procedure is proposed to synthesize single‐crystal gold microflakes with planar area up to 104 μm2. This unprecedented dimension offers new possibilities in designing flexible conductive films with tunable strain‐dependent conductivity, that can be exploited in strain/force/vibration......
  • Enhancing reducing ability of α-zein by fibrillation for synthesis of Au nanocrystals with continuous flow catalysis.Chen, Y. , Wu, X. , Lv, L. , Li, F. , Liu, Z. ,  Kong, Q. , Li C. (2016) Journal of Colloid and Interface Science, S0021979716307561.
    Green low-cost synthesis and efficient recyclability are two major hindrances for Au nanocrystals as catalysts applying in diverse industrial reaction processes. By the use of low-cost α-zein (i.e. a major storage protein of corn) as the reductant, capping agent and stabilizer, Au nanocrystals with tunable catalytic......

  • Single-crystal Au microflakes modulated by amino acids and their sensing and catalytic properties.Li, M., Wu, X., Zhou, J., Kong, Q., & Li, C. (2016). Journal of colloid and interface science, 467, 115-120.
    Single-crystal Au microflakes with the planar area over 103 μm2 (i.e. being accessible to the human eye resolution) were synthesized in an environment-friendly route by directing two-dimensional growth of Au nanocrystals into macroscopic scales with amino acids as both reducing agents and capping agents. Side groups......
  • Modulating Zn(OH)2 rods by marine alginate for templates of hybrid tubes with catalytic and antimicrobial properties. Lv, L., Wu, X., Li, M., Zong, L., Chen, Y., You, J., & Li, C. (2016). ACS Sustainable Chemistry & Engineering, 5(1), 862-868.
    With the help of marine alginate, Zn(OH)2 nanorods were synthesized under mild conditions (e.g., room temperature and atmospheric pressure) through a one-step, green, and scalable method, in which both the morphologies (e.g., nanorods and nanoflakes) and nanoscale sizes of Zn(OH)2 could be precisely controlled by al......

  • Amyloid-graphene oxide as immobilization platform of Au nanocatalysts and enzymes for improved glucose-sensing activity. Wu, X., Li, M., Li, Z., Lv, L., Zhang, Y., & Li, C. (2017). Journal of colloid and interface science, 490, 336-342.
    Two-dimensional GO nanosheets and one-dimensional lysozyme nanofibrils were hybridized through electrostatic interaction to get a novel amyloid-GO composite, which promised a biocompatible immobilization platform for Au nanocatalysts as well as enzymes. The immobilization platform could load a large and tunable amou......

  • Alginate-assisted synthesis of hollow micro fi bers assembled by SnO2 nanoparticles. Zhao, Y., Li, M., Qiu, J., Kong, Q., Zhang, Y., & Li, C. (2016). Materials & Design, 101, 317-322.
    A novel alginate-involving method has been developed to prepare hollow SnO2 micro fibers, in which a wet spinning process was combined with pyrolysis oxidation to facilitate scalable production. The resulting hollow SnO2 micro fibers consisted of numerous SnO2 nanoparticles with pure tetragonal phase within the micr......

  • Guiding growth orientation of two-dimensional Au nanocrystals with marine chitin nanofibrils for ultrasensitive and ultrafast sensing hybrids. Chen, Y., Liu, Z., Li, M., Wu, X., You, J., & Li, C. (2017). J. Materials Chemistry B, 5(48), 9502-9506.
    We demonstrate that marine chitin nanofibrils are able to modulate the growth direction of two-dimensional Au nanocrystals from nanoribbons, nanokites to nanosheets. The mechanism investigation reveals that deacetylation and exfoliation of chitin nanofibrils are essential to template dire......
