Nanofibers produced by electrospinning are already being used in a vast array of products in many industries. However, the volume of production of nanofibers has been being a bottleneck restricting their applications....
Further to the rapid enlargement of an aneurysm to 5.6 cm in diameter after 3 years of surveillance, a 79-year-old patient was fitted with a Vanguard modular stent graft and monitored on a regular basis for 6 years. T...

Nanoscale titanium dioxide functional films were prepared on the surface of the cotton woven fabric and the polyester knitted fabric at room temperature by Radio Frequency （RF） magnetron sputtering process. The surface microstructure and morphology were characterized by scanning electron microscope （SEM） and X-ray diffraction （XRD）. Photocatalytic property of two treated fabrics was tested in solar and ultraviolet （UV） radiation respectively, and their photocatalytic activity was compared. The results showed that the nanoscale titanium dioxide deposited on the surface of the treated fabrics was at different anastasia phase. The treated fabrics have excellent photocatalytic property, and after 30 launderings, the photocatalytic activity still maintained at a high level. Also, it indicated that the photocatalytic activity of the treated fabrics in UV radiation was higher than in solar radiation, but the effect wasn＇t very distinct. And at the same experimental magnetron sputtering parameters, the cotton coated with the nanoscale titanium dioxide showed better performance than the polyester fabric coated with the nanoscale titanium dioxide in terms of the photocatalytic property.
