The results show that the surfaces of the films are uniform and compact with a root-mean square roughness about 0.30 nm. CuS particles I hextognal phase are dispersed in Fe2O3 matrix with a size of about 20 nm in diameter.
The results indicate that Cu-Al2O3 composites are prepared successfully by the simplified technique,a mass of fine Al2O3 particles are dispersed in the copper base,the size of Al2O3 particles is about 10~20 nm in diameter,and the spatial distance between particles is about 25～60 nm.
When the current,total pressure,voltage,H2 content and fan rotating rate are 500 A,0.03 MPa,32 V,50% and 2 400 r/min respectively,the yielding output can reach up to 6.2 g/min and the average diameter of powder is 50 nm. Most of nano-iron powder are spherical and has smooth surface,the size of particles is uniform and these particle is chainlinked.
CETP thus plays a potential pro-atherogenic role by moving CE from HDL into pro-atherogenic VLDL and LDL particles, thereby lowering atheroprotective HDL cholesterol.
In this study, a novel method was used to prepare well-separated and spherical tricobalt tetraoxide (Co3O4) nanosized particles.
Transmission electron micrograph image showed that the catalyst particles were highly distributed on the surface of CNTs.
Preparation of raspberry-like PMMA/SiO2 nanocomposite particles
Water-borne raspberry-like PMMA/SiO2 nanocom-posite particles were prepared via free radical copolymerization of methyl methacrylate (MMA) with 1-vinylimidazole (1-VID) in the presence of ultrafine aqueous silica sols.
