Sn doped SiO2nanoparticles have been synthesized using a reverse micelle technique combined with metal alkoxide hydrolysis and condensation. The size of the particles and the thickness of the coating can be controlled by manipulating the relative rates of the hydrolysis and condensation reactions of tetraethyl orthosilicate (TEOS) within the micro-emulsion. The properties of the Sn doped SiO2nanoparticles were studied as a function of various processing parameters such as R and H value. The average size of synthesized Sn doped SiO2nanoparticles was about in the size range of 20-40 nm and core particle (Sn) 1-5 nm. The Sn doped SiO2nanoparticles were characterized by X-ray diffraction (XRD) and Transmission electron microscopy (TEM).

In this paper, cathode material nickel hydroxide powder of MH-Ni battery was prepared through the method of micro emulsion deepfreeze deposition with the system of Tween-80/n-C4H9OH/c-C6H12/NiSO4 solution. By measurement of the maximum content of water of different micro-emulsion system, optimum system was determined. The effect of temprature, concentration and amount of nickel sulfate solution to the particle size of the sample powder was also discussed. The structural morphology of the sample powder were analyzed and measured by XRD, SAED, SEM, TEM and particle size distribution of the sample was also analyzed. The results showed that the sample was amorphous nano-sized particles, and the size distribution was wide.

A novel, simple and efficient method to prepare a new kind of nanocapsules in a demulsifying W/O micro-emulsion system from low molecular weight (MW) alginate and oligochitosan (OCS) was reported. Low MW alginate (LMWALG) was prepared by radiation of UV in the presence of cathode ion, OCS were used as anode ions. The composition for LMWALG demulsifying W/O micro-emulsion system is 50.75% (wt) of cyclohexane, 17.67% (Triton X-100 + n-pentanol), and 31.58% of LMWALG gelatum, while that for OCS one is 48.21% of cyclohexane, 16.09% (Triton X-100 + n-pentanol), and 35.70% OCS aqueous solution. The preparation of nanocapsules was optimized based on the above compositions for the MW of alginate, the MW of OCS, concentration of OCS and the encapsulation time. Ultimately the MW of LMWALG is 0.13 million and that of OCS is 3000 with a concentration of 1%, encapsulating for 30 min, under the above optimal conditions nanocapsules were formed in diameter of 136 nm.
