Introduction Hip prostheses materials.
Nanomaterials – which include nanoparticles and nanocrystalline materials that are readily manufactured and can substitute less performant bulk materials – can be also used as biocompatible materials or coatings in bone replacements, prostheses, and implants [9].
To improve the mechanical properties of prosthesis, they were made of different materials, were processed or coated with various materials, which have superior properties.

In this research , Ni (for low aspect ratio) and Si(for high aspect ratio) were used as the materials of the stampers.
For precise measurement of the temperature of the stampers and materials, not only the thermocouplers but also the infrared camera (NEC, Thermo Tracer, TH5104) were used (see Fig. 5).
A PMMA (dimension: 2x2x0.1cm) was used as the embossing material.

Introduction In the recent decade nano materials are playing very important role in the material science research.
The enhanced properties in the characteristic behaviors after the size reduced to nano region made a great attraction towards nano science.
Transition metal dichalcogenides (TMDs) nano materials such as Tungsten disulfide WS2 were used in many fields such as electronics, photonics, spintronic [1] solid lubricant, catalyst, photosensitive films [2].
In the same method some other inorganic materials also can be synthesized such as MoS2, MoSe2 and WSe2[2].

Solute-vacancy First-principle value, present work [eV] Zn – Va 0.032 Mg – Va 0.026 Cu - Va 0.124 Simulation of precipitation strengthening The remarkable strength increase in Al-Zn-Mg(-Cu) alloys during natural aging can be attributed to a high number density of GP-zones with 5-20 nm diameter [[] Fuller C.B., Mahonex M.W., Calabrese M., Micona L., Materials Science and Engineering (2010), A 527, 2233-2240 ].

Experimental material.
But it was a materials which can absorb the energy in the microwave field, and can speed up the velocity of zeolite synthesis[3].
Conclusions (1) Coal fly ash contains some of the microwave absorption materials in the microwave field which can be used as a catalyst to promote the synthesis of zeolite.
(3) Coal fly ash are acted as the raw materials to produce zeolite, which was a better utilization of coal fly ash way.

Experimental The polymeric materials used to prepare the nanocomposites thin films were Poly(vinylidene flouride) powder (PVDF), (Mw~534,000) supplied by Sigma Aldrich and were used without further treatment.
This finding was supported by Natori et. al, which stated that the dielectric constant of high dielectric materials decreases as the film thickness is decreased.
Several studies indicated that these curves were related to the dielectric relaxation of polymeric materials.
From Fig. 3, the nanocomposites experienced β-dielectric relaxation at high frequency, consistent to Bӧettcher study which stated that the curve of β-dielectric relaxations was contributed by the zigzag conformation of polymer materials, which resulted in high dielectric constant of a polymer material.
