This paper explores the mechanical properties and fracture analysis of C2N-h2D single-layer sheets using classical molecular dynamics (MD) simulations. Simulations are carried out based on the Tersoff potential energy function within Nose-Hoover thermostat algorithm at the constant room temperature in a canonical ensemble. The influences of boron (B) doping on the mechanical properties, ...

Investigating the longitudinal optical conductivity of graphene systems, which is the mostimportant property for opto-electronic devices, for three-layer graphene systems theoretically and numerically is the main purpose of this study. Each layer can be mono- or bi-layer graphene. Separation between layers has been denoted by d, selected to be about ten nanometers. The carrier densities i...

Crystalline arrays of proteinaceous subunits forming surface layers (S-layers) are now recognized as one of the most common outermost cell envelope components of prokaryotic organisms. The surface layer protein of Lactobacillus acidophilus ATCC4356 is composed of a single species of protein of apparent molecular weight of 43-46 KDa. Considering the Lactobacillus acidophilus ATCC4356 having the ...

in this paper, vacuum assisted resin transfer molding (vartm) method was simulated by analytical solution. then the effect of parameters like fiber density, distribution of layer thickness, perform layer thickness, resin viscosity was investigated theoretically. obtained results show that by selecting optimum distribution layer thickness, increasing fiber volume fraction, reducing viscosity of ...

Since the cutting tools used in machining process of super alloys are subjected to high cutting forces, accordingly tools life is reduced, therefore improvement in alloys machining and reducing cutting forces to achieve longer tools life is an essential necessity. In this research, the effect of changes in feed rate on cutting forces in machining process of nickel based super alloys is investig...

In this research a layer of Ni-Cu-P was deposited on 304 stainless steels by using gelatin and thiourea as additives in a sulfate solution. In order to determine the properties of deposited layers, a microhardness tester was used for microhardness measurement, X.R.D. for microstructural analysis, and a scanning electron microscope equipped with E.D.X. for determining morphology and analyzing th...
