Therefore the seat surface should use elastic material or glass fiber material according to the buttock pressure distribution, increase the comfort and freedom.
Also the backrest and the human body larger contact area and meet the needs of the backrest, so using elastic mesh technique or try the application of nano-materials or "memory" material to make uniform pressure distribution, and better air permeability so that the back can comfortably lean and adjustment.

According to the scientific literature it is known that, in particular, the silver nanoparticles may be used to produce a wide range of materials with antibacterial properties.
They will also allow determining and developing science-based and acceptable ranges of concentration and size of nanoparticles, depending on their location: in water, air or as a part of various materials, which a human contacts with.
Synthesis of nanosized silver particles is carried out by chemical reduction, thermolysis and photolysis, as well as radiation chemistry, using various nanostabilizing materials mainly of synthetic origin: solid matrices, water and organic emulsions, macromolecular solutions [26 – 28].

Both models assumed nonlinear B-H properties for magnetic materials, i.e., the mild steel for the thrust plate and the ARMCO iron for electromagnet cores.
The material of the electromagnet cores was defined as the ARMCO iron and the material of the thrust plate was defined as the mild steel (both magnetization characteristics are shown in Fig. 3).
The mechanical properties of the thrust plate material are listed in Table 5.
Further tests would require an examination of dynamic behavior of the bearing, a development of the model that takes into account dynamic properties of magnetic materials and a comparison of the obtained results.

Composite materials are being used to build the world’s most advanced military aircraft such as the F/A-22, B-2B, F-15E and the Joint Strike Fighter.
CFRP materials that are similar to those used on military airplanes are now being designed into the Dreamliner.
It is generally accepted that, under most circumstances, titanium is highly resistant to corrosion, even when in contact with CFRP materials.

They include AlGaN/AlN quantum wells (MQW) emitting in deep UV region (shortest stimulated emission of 258 nm reported up to date in semiconductor materials) [1] as well as high-power AlGaN/GaN/AlN HFETs being superior than analogous devices made on SiC [2].
The AlN source powder material was contained inside elongated tungsten crucible.
Journal Title and Volume Number (to be inserted by the publisher) 3 If we consider evaporation into vacuum, i.e. the vapor is stoichiometric, pN2= ½ pAl and the mixture will contain only 1/3 of nitrogen [9].
The source material was carefully purified by repeated sublimation prior to growth.

The electropulsing has been widely applied to materials processing and attracted more and more attention for use, especially in the metallurgical process of metallic materials [1-4].
It has been recognized that in metallic materials, dissipation of electronic excitation into heat is very fast and the rate of the temperature rising can achieve 10 6 °C ·s-1 order [9].
