However, further research is needed because the effects of the reinforcement on properties of the composite are still not comprehensive, and greatly affected by the additives and parameters of sintering process.

The full cycle of surface modification of the backbone with polyvinylpyrrolidone and drugs permitted to increase significantly the atrombogenic and antimicrobial properties of prostheses and provide its effective matrix properties.
The undoubted advantage of such modifications is that this approach allows one to directly adjust the surface properties of the material without changing its mechanical characteristics.
The simplest way to assess the properties of a surface is evaluation of its wettability with water under the advancing conditions.
(1) New tissue-engineered vascular prostheses of small diameter with effective matrix properties have been created.
However, ionizing radiation can affect biocompatibility properties.

Macro Hydroforming Micro hydroforming has some similarities to macro hydroforming, therefore the research methods and key factors in macro hydroforming can be drawn on for study of micro hydroforming.
Moreover, ignorable factors at macro scale, such as surface tension and Van der Waals force, become significant and should be considered.
Given the inhomogeneity of material, twelve different regions were chosen to obtain the material properties.
Then, these twelve material properties were applied in the FE model to represent randomness of grain characteristics.
Then Voronoi tessellation was employed for representing microstructure, where each Voronoi cell stands for one grain with different properties [25].

Introduction Zirconia (ZrO2) has been extensively investigated due to its unique chemical, physical, optical, dielectric and mechanical properties.
When produced in a form of nanotubes, it is anticipated that the properties of ZrO2 can be further enhanced.
Of these parameters, electrolyte composition has been seen as an important factor.
It appears that the surface morphologies of the underlying substrate are affecting the length of the ZNTs whereby surface in-homogeneity and modulation resulted in nanotube lengths variation across the anodic film.
However, as can be seen in Fig. 1 (c), surface etching is affected by water content with the best etching for sample made in 3 ml-water/EG.

When all these factors are taken into account, the increase in mechanical properties with the decrease in size can be estimated.
Therefore, crack initiation on particle surface is more likely to occur, affecting life duration of the component.
The knowledge of properties of the composite material, such as tribological properties, is fundamental for the design stage.
The optimal method to determine such properties for nanocomposite materials needs to be established.

Huang and Tai [5] studied factors affecting the warp of thin-shell injection parts using C-Mold and the Taguchi Method.
The location, number, shape, and size of the gate directly affect the appearance, size precision, properties, and molding efficiency of the product.
Without affecting the performance of products and molding efficiency, the length, width, and height of the gate were shortened.
Table 4 shows physical properties of ARTON F5023 plastic.
Measurement was taken when its properties became stable.

Drying process can be affected by internal and external conditions of the process which affect moisture migration and heat transfer mechanisms into the material.
Mathematical Modeling To model the drying process of clay solids with arbitrary shape, the following considerations were adopted: (a) The ceramic solid is homogeneous and isotropic; (b) The distribution of moisture and temperature inside the solid are uniform during the process; (c) Thermo-physical properties are constant during the transient process; (d) The drying phenomenon occurs by heat and mass diffusion within the solid and mass and heat convection and evaporation, at the surface thereof.
The area/volume relationships of material is a factor that offers big influence in the drying process.
e) The surperficial area of the product that is exposed to drying and volume of the solid are important factors in drying.

It is mostly located by the material's properties and size.
Some important properties of L-asparagine amino acid are given here.
Each mineral exhibits unique X-ray diffractive properties determined by its atomic composition and the arrangement of its crystal lattice.
All formed crystals in the current investigation had work hardening factors that are higher than 1.6.
