A novel nanofiber composite nano-filtration membrane was prepared by combination of grafting, electrospinning and surface coating. First, carboxyl multi-walled carbon nanotubes were grafted onto bacterial cellulose molecular chains by solution reaction. The grafting products were characterized by TEM, FTIR, Raman, XPS and TGA measurements. Then, they were electrospun into nanofibers to be the supporting...
La1-xSmxMgNi3.6Co0.4 (x = 0∼0.4) alloys were prepared by a vacuum intermediate frequency induction furnace with a high purity helium gas as the protective atmosphere. The effects of partially substituting Sm for La on the phase structure, morphology and hydrogen storage properties of the alloys were investigated. The detections of XRD and SEM reveal that the as-cast alloys contain two phases, LaMgNi...
