HAP and TiO2 nanoparticles were incubated with the Bet- 7402 cells for 1 h and 8 h respectively. Then, cancer cells were collected and examined under transmission electron microscope （TEM）. In cytoplasm, nanoparticle were contained in some vacuoles. Some death features of cell appear. The experimental results indicated that ICN can induce cancer cells death.展开更多

The element gi of adjacency matrix was defined as gi=（1＋Zi^1.4）/（1＋ri^1.4）, where Zi and ri are the charge number and the thermochemical radius of ion i respectively, and the radii ri for metal ions are taken to be the Goldschmidt radius. The regression analysis by the connectivity index 1G can provide a high-quality QSPR model for the lattice energies of 245 complex inorganic ionic crystal samples. The results imply, that the lattice energies may be expressed as a linear model of the connectivity index 1G. For the linear model the correlation coefficient r and the standard error s are 0.9998 and 228.72 kJ/mol, respectively. The cross-validation by the leave-one-out method demonstrates that the model is highly reliable from the point of view of statistics.展开更多
