The leaking of the material between the pistons is prevented by PTFE sealing.
In case of semi-crystalline materials the melting and the crystallisation temperature always differ from each other because of thermodynamic reasons, as a result the difference between the results of the measurements can be significant depending on the material being heated or cooled during the analysis.
Wang et al. [3] built a special injection mould which enabled the examination of amorphous and semi-crystalline materials applying isobar heating.

Introduction The properties and behavior of materials at the nano-scale or level vary greatly when compared to micro levels.
Metal oxides NPs (core& shell) have many applications in the field of catalysis and optoelectronics because of their dual physical properties for core as well as shell materials.
SDS is helpful organic polymer solvent to fabricate nanocompound materials and to ensure the stability of these materials.
NPs are formed during the process of PLAL by many steps staring in phase transition, nucleation, and crystal growth of emitted materials from the target plate.
This convenient synthesis strategy can be applied as a general approach that ZrO2 NPs have attracted significant interest of materials scientists and physicists due to their special properties and have attained a great importance in several technological applications such medical ,and biological applications.

In order to purification of natural gas, we need to find a kind of materials with high adsorption capacity for impurity gas while low adsorption capacity for methane gas.
The introduction of AEMs weakens the adsorption of CH4 since ΔEads of CH4 on other materials as graphene functionalized20-21.

For the physical mechanism of the dielectric relaxation, it was found that the effect of grain sizes for the high-k materials’ structure mainly originates from higher surface stress in smaller grain due to its higher concentration of grain boundary.
Introduction Oxide materials with larger dielectric constants (so-called high-k dielectrics) than 3.9 (SiO2’s dielectric constant) have attracted much attention due to their potential use as gate dielectrics in MOSFETs to overcome the gate leakage problem [1].
