The modified nanometer-sized TiO2 as a solid sorbent was prepared by using impregnation method, and characterized by using SEM. The adsorption properties of the sorbent to Co(II) in static system, main factors affecting the adsorption and desorption, adsorption isotherms and influence of coexisting ions on the determination of Co(II) were investigated by FAAS, and regeneration experiments were carried...
In order to overcome the above-mentioned negative effects, the extractives of the fresh Cunninghamia lanceolata shavings, which were obtained by using both the sorbitic-extracting approaches, were analyzed by ZETA and SIZER to find out the leaching rule of nano particles in Chinese-fir wood. The results are as follows: (1) The extraction mass arrived at the maximum value when NaOH concentration is...
The lead telluride (PbTe) nanoparticles have been synthesized under ultrasonic/microwave co-irradiation. These PbTe nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR) and DSC.
In this study, Sn-0.7Cu solder alloy was reinforced with Al2O3 (50 nm) and ZrO2 (45 nm) nano particulates to form Sn-0.7Cu/Al2O3 and Sn-0.7Cu/ZrO2 composites. The volume percentge of the Al2O3 and ZrO2 nanoparticulate reinforcement was kept at 1.5%. The composites were synthesized using powder metallurgy technique assisted with microwave sintering and incorporating hot extrusion as secondary processing...
