Introduction The transport of thermal energy across an interface between two different materials is playing an ever increasing role in thin-film and nanostructure device.
The Lennard-Jones parameters for materials B and C have been systematically modified: εB=α1εA, σB=σA, mB=mA, εC =α2εA, σC=σA, mC=mA, where α1 and α2 are proportionality constants.
Conclusion In summary, Nonequilibrium molecular dynamics (NEMD) approach is developed to investigate the thermal transport across a solid-solid interface between two different materials with an interlayer around it.
Moreover, interface thermal resistance determined by the interlayer materials does not depend strongly on the simulation system size.

Many different physical effects are applied to optical isotropic and transparent materials that cause them to behave as optical active materials, where they are able to rotate the polarization level of the polarized light linearly and pass through it [8], [9], [10].

The APF of bulk hexagonal ZnO materials is about 0.74, however in our investigation, the APF of Zn(1-x)MnxO nanoparticles is nearly 0.75.
It implied that APF values in nanocrystals are somewhat larger than that of bulk materials.
It is possibly due to the size effect in the nanocrystalline materials.

FOREWORD We do our best to increase the quality, scientific novelty and the engineering significance of published materials that, in the first place, will be very useful for young researchers.
Journal “Advanced Engineering Forum" is a periodical journal and overs a wide range of engineering sciences from different branches of human activity.
Modern developments in applied and engineering sciences are generated rapidly as a result of interdisciplinary research and scientific solutions at the intersection of various branches of human knowledge.
This volume of the journal was created on these principles.
We hope that our journal will be useful to your scientific work.

The prepared materials’ crystal structure and morphology were characterized by TG-DTA, XRD, FT-IR and TEM.
Thus this technology effectively solved the problem of “agglomeration” which usually occurred in preparation process of ultrafine materials.
Although we synthesized materials with chemical stoichiometric amount of n (La3+): n (Co3+) = 1:1, when the temperature is higher than 900, during the process of thermal treating, some LaCoO3 will be decomposed into La2O3 and Co2O3.
This is inevitable in process of preparing these materials by Sol-Gel method.
