Hollister Co Canada,Cloth0713,mechanics the surface energy is usually

In conventional continuum mechanics, the surface energy is usually small and Hollister Co Canada negligible. But at nano-length scale, it becomes a significant part of the total elastic energy due to the high specific surface area of nanomaterials. A geometrically nonlinear finite element (FE) model of nanomaterials with considering Hollister Canada Stores surface effects is developed in this paper. The aim is to extend the conventional finite element method (FEM) to analyze the size-dependent mechanical properties of nanomaterials. A numerical example, analysis of InAs quantum dot (QD) on GaAs (0 0 1) substrate, is given in this paper to verify the validity of the method and demonstrate surface effects on the stress fields of QDs. Single crystal of Li4Ti5O12 was synthesized by a flux method using LiCl flux. The obtained Li4Ti5O12 single crystal is colorless and has the shape of a rod. Li4Ti5O12 crystallizes in the cubic spinel type structure, space group <img height="16" border="0" style="vertical-align:bottom" width="40" alt="View the MathML source" title="View the MathML source" src="http://origin-ars.els-cdn.com/content/image/1-s2.0-S0022369707006373-si1.gif">Fd3¯m, a=8.352 (4) Å, V=583.6 (8) Å3, and Z=8. The structure was determined by a single-crystal X-ray study and refined to the conventional values of R=3.6% and wR=3.3% for 209 independent observed reflections.
