Hydrogen production with a proton exchange membrane (PEM)electrolyzer utilized renewable energy power is considered to be an efficient and clean green technique, but the poor oxygen evolution performance results in high consumption low efficiency. In this work, strategy reported for construction of support network anodic catalyst layer simultaneously ameliorate its sluggish reaction kinetics ma...

The interphase properties in nanocomposites indicate the interaction between filler and matrix, which is dependent on preparation method, shape, size of chemical two phases. Local environment polymer matrix give rise to different dielectric compared that bulk material. These allow understanding their effects glass transition (Tg) nanocomposites. In this study, power law model was used predict b...

A reusable photocatalytic TiO2/CoFe2O4 composite nanofiber was directly formed by using a vertical two-spinneret electrospinning process and sol-gel method, followed by heat treatment at 550 degrees C for 2 h. The high photocatalytic activity of the composite nanofibers depends on the good morphology of the fibers and the appropriate calcination temperature. The crystal structure and magnetic p...

A photocatalytic membrane combining photocatalyst and technology based on polyacrylonitrile (PAN) TiO2/CNT has been developed. Such combination is to overcome fouling formation the membrane, thus prolonging lifetime enhancing efficiency waste treatment. PAN nanofiber was prepared by electrospinning method. The precursor solution dissolved dispersed in N,N-Dimethylformamide (DMF). concentration ...

We report here, for the first time, a novel multi-scaled hybrid orthopedic implant material consisting of a macroporous Ti scaffold, whose macropores' walls have a microporous titania layer which is fully covered with nanofibers of Sr-doped hydroxyapatite (Sr-HA). The microporous titania layer is formed on and within the Ti scaffold by micro-arc oxidation, which firmly binds to the Ti substrate...

Doping of titanium dioxide nanofibers by silver nanoparticles revealed distinct improvement in the photocatalytic activity; however other influences have not been investigated. In this work, effect of sliver-doping on the crystal structure, the nanofibrous morphology as well as the photocatalytic activity of titanium oxide nanofibers has been studied. Silver-doped TiO2 nanofibers having differe...
