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.

Swelling and shrinkage due to moisture-change is one of the expansive soil’s characteristics, which is similar to the behavior of most materials under thermal effect.
It is reasonable to assume that the swelling-shrinkage behavior due to moisture-change is similar to the temperature effect on most solid materials which can be analyzed widely and maturely by thermo-mechanics theory.

In this paper, compare some methods and materials.
In such methods researchers heat some materials to 900 Celsius degrees and provide hydrogen and some other materials[7].
Researchers used sulfuric acid and some other materials like iodic salts in these studies.
Furthermore, water steam and other materials should be conducted toward given tanks.
- Water is also one of the most plentiful materials on the earth

Shape Memory Alloys (SMA) are smart materials that have attracted increasing attention due to their superior damping properties when compared to conventional structural materials.
Differently from active materials, the classical engineering materials have only structural functions when used in mechanical systems.

The specimen consisted of two materials.
Feasible materials of this part are steel or copper.
For the latter, two cases were considered – a sharp interface between the two materials and a gradually changing one.
Firstly, the interface between materials was a plane.

Metallic oxide materials with AB2O4 structure are very interesting for technological applications.
Recent studies have also focused on the development of novel synthesis techniques for the production of nanoxide materials.

New Thermal Insulation Materials from Waste of Mechanical Processing of Wood A.A.
Materials and Methods Studies The object of the study is the processes of creating new thermal insulation materials obtained from the waste of mechanical processing of soft hardwood wood.
In the production of wood products, up to 60% of the waste from the total volume of processed raw materials is generated.
The remaining waste (humps and slats after processing into small wood particles, as well as sawdust, shavings and crushed wood) is widely used to produce composite materials and therefore they are considered as additional raw materials.
Products based on gypsum binders are more environmentally friendly than many materials, cheaper and have a large raw material base.
