To develop new stent coating materials, it is critical to selectively inhibit smooth muscle cell proliferation without affecting the proliferation and repair of endothelial cells.
Discussion Current coated drug stents are mainly rapamycin and paclitaxel-eluting stents.The non-selective cytotoxicity of the coating materials can induce the endothelial damage.
To develop new highly efficient and specific stent coating materials, it is critical to inhibit smooth muscle cell proliferation without affecting endothelial cell repair.

The theoretical development of the size effect mainly due to experimental study of metallic materials.
Recent experiments revealed that the metallic materials in the micron and submicron scale has a strong size effect. [1-7] at the same time, many studies show that significantly strain gradient effect exist in the geotechnical medium, [8-9] These articles only study macro-mechanical indicators.
"Matrix - strengthen Particle" model Soil belongs to the friction materials, the shear deformation associated with soil micro-cracks.
The fitting curve of different soil yield stress Conclusions Though soil is a very complex natural materials, it have been depart as the matrix particles and the strengthening particles in this article.

But, the fracture remains a key failure mode of these materials.
For homogeneous, isotropic and linear elastic materials, the eigenfunctions or higher order fields are only three ones, i.e.
However, the corresponding eigenfunctions are not available for non-homogeneous, isotropic and linear elastic materials.
Moreover, it is seen from the above-developed solutions that they consist of two parts: the classical solution for homogenous materials and additional terms due to non-homogeneity.
Therefore, if we use the expansions available for homogeneous materials in order to extract fracture parameters from full field experimental data, this could lead to serious errors.
