The accumulation of waste rock on the ground could be eliminated by using as goaf filling, reclamation area filling, and building materials.
Moreover, the post-secondary tailings after separation could be comprehensive utilized as raw materials for walls (such as block and burn-free brick).
So, it could be applied as building materials and raw materials of cement production to improve the comprehensive utilization of associated resources.

We discussed the concentration of solution reflected on the appearance of ZnO nanostructure materials, and obtained flower, rod, and tub structured ZnO nanomaterials respectively.
So we could have a higher efficiency if we use the ZnO nanoflower structure materials in QDSSCs.

Three types of materials are used which consists of mild steel as reference materials, Aluminum AA5182, E-glass/epoxy composite and carbon fiber/epoxy composite with four different fiber configurations.
The results for the composite materials are compared to that of steel to find the best material with lowest HIC values.
Suitable materials that can be used to replace mild steel can be determined.
Material type 24 (mat_piecewise_linear_plasticity) are used for simulation of metallic materials.
Material type 54 and 55 (mat_enhanced_composite_damage) are used for simulation for the composite materials in this study.

Introduction In the present times, the plant raw materials from annual growing plants are getting more attention of pulp and paper industry specialists.
This is due to the availability and low cost of the raw materials, which is considered waste for the agriculture.
When using electrochemical oxidation siliceous materials in the form of silicic acid were removed from alkali hydrolyzate with simultaneous neutralization of alkali reagent solution.

The microstructures and properties of these materials were investigated in this paper.
Experiment Materials.
For these materials, the mechanical properties mainly depend on fiber’s strength.
It may be harmful for those materials that are used as thermal insulation.
