,Central South University, Changsha 410083, China) Abstract: Surface energy parameters of pyrite mineral and Thiobacillus ferrooxidans were obtained by calculating according to deduced formula of Youngs equation and contact angel. The results show that surface energy of Thiobacillus ferrooxidans is much higher than that of pyrite mineral. By thermodynamics approach, the interaction free energy......
of the two kinds of surfaces are also analyzed. The results show that the surface energy of Ti-terminated is lower in much wider range compared with that of B-terminated surface. So it can be believed that Ti-terminated surface maybe the stable TiB2 (0001) surface. Key word: TiB2 (0001) surface; density functional theory; surface relaxation; surface energy  ......

of molecular mechanics, the reason for the occurrence of surface relaxation is that when a new surface is formed, the stress on the surface atoms is out of balance, resulting in high surface energy. Such a surface is unstable; to reach stability, the surface atoms shift in a direction normal to the surface so as to lower the surface energy. The shift in each layer is different, and the more obvious......

. The dendrite growth process of Ni-Cu alloy with strong surface energy and kinetic anisotropy were simulated. The results show that the dendrite growth depends on the two kinds of anisotropies. Under the strong surface kinetic anisotropy condition, the melt solidifies grow along the á110? orientation and the crystals grow into a square-like. Under the strong surface energy anisotropy or having two kinds......
