When the electromagnetic frequency is 20Hz, the grains with developed secondary dendrites trend to be eliminated, and the grains are mainly the short rod or rosette-shaped structures, shown as Fig.3 (b). when the electromagnetic frequency is 30 Hz, the microstructure of the billet is composed of the homogeneous and fine rosette-shaped equiaxed grains, and the distribution of grains is more homogeneous, the size of grain is refined obviously, shown as Fig.3 (c).

Abstract.
Presence of oil phase in the water-coal slurry enables the increase of hydrophobicity of lignite powder and achievement of a specific hydrophilic - hydrophobic balance of the surface thereof, which is required for the formation of constant coagulation structures.

The ground CaCO3 (GCC) and others ground CaCO3 which surface coated with nanometer needle-shaped CaCO3 or spherical CaCO3 with a particle size range of 20 ~ 100nm, named as needle-shaped CaCO3 (NCC) and the spherical CaCO3 (SCC), supplied by the State key laboratory breeding base of green chemistry-synthesis technology, Zhejiang University of Technology.
That’s because needle-shaped CaCO3 and spherical CaCO3 with nano–structure surface increased their specific surface area which enhanced the interaction with the matrix.

Abstract. 3C-SiC layers have been grown by using sublimation epitaxy at a temperature of 2000°C,
on different types of on-axis 6H-SiC(0001) substrates.
The crystal structure was assessed by HRXRD, using Philips X'Pert MRD triple axis diffractometer equipped with a symmetric 4 × Ge 220 monochromator and symmetric 3 × Ge 220 analyzer using Cu radiation.

Keywords: Rapeseed acid; complex ester; biodegradable rate; lubricity
Abstract: Several complex esters were synthesized from phthalic anhydride, neopentyl glycol and rapeseed acid.
The degree of polymerization(m) of intermediate 1 is in the range 1.42~4.52; then intermediate1 reacted with rapeseed acid, after which purification of the complex esters was accomplished, The structure of the product was confirmed by infrared spectroscopy.
