Preparation of Nanophase Titania Film by Plasma Spraying
Zhu, Yingchun,Huang, Minhui The Korean Vacuum Society 1997 Applied Science and Convergence Technology Vol.6 No.1
Nanophase titania film was obtained by plasma spraying. The structure of titania film was investigated with transmission electron microscopy (TEM). It was found taht the film was composed of grains with mean particle size of 15nm. The crystal structure of nanophase titania film was found to be anatase phase by electron diffraction.

L-arabinose and D-galactose could be released during the hydrolysis process of Arabic gum. The development of a crystallization process of L-arabinose is highly dependent on the knowledge of the solubility of both saccharides. In this work, the solubility of L-arabinose and D-galactose in binary mixtures of methanol-water or ethanolwater (mole fraction of water 0.5816) was determined at temperatures between 278.15 and 333.15K by a static equilibrium method. The experimental data correlated well with the modified Apelblat equation, the simplified polynomial empirical equation, NRTL model and UNIQUAC model. Additionally, the thermodynamic properties including the dissolution enthalpy and entropy were obtained from the experimental data. Within the studied temperature range, the dissolution is endothermic and the dissolution process is non-spontaneous.
