A water and mildew proof SiO2 and ZnO/silica sol superhydrophobic composite coating was prepared by a one-step method and applied to a circuit board. The preparation method is simple and inexpensive, and convenient for large-scale preparation.
Micro-gradient structured PAN sub-micro fibrous membrane with high-efficiency air purification performance was fabricated via one-step free surface electrospinning with large-scale yield, firstly demonstrated as air filters.
A facile two-step method is developed for large-scale preparation of graphene-based three-dimensional hierarchical sandwich-type architecture (graphene/carbon nanotubes (CNTs)/Mn2O3) for high performance supercapacitor.
The TiO2/amorphous carbon composite, with narrower band gap caused by oxygen vacancy, doping carbon and bridging hydroxyls, has good visible light property. In the photodegradating RhB process, hole and superoxide radical are the main active species.
SummaryFactor VIII can be isolated from plasma proteins, including fibrinogen by chromatography on agarose. The best results were obtained with Sepharose 6B. Large scale preparation is also possible when cryoprecipitate is separated by chromatography. In most fractions containing factor VIII a turbidity is observed which may be due to the presence of chylomicrons.The purified factor VIII was active in vivo as well as in vitro.
