in present study, thermo-elastic buckling analysis of multi-layer orthotropic annular/circular graphene sheets is investigated based on eringen’s theory. the moderately thick and also thick nano-plates are considered. using the non-local first and third order shear deformation theories, the governing equations are derived. the van der waals interaction between the layers is simulated for multi-...

− The tool of immunological diagnosis denominated ELISA (Enzyme Linked Immuno-Sorbent Assay) it is probably the most used colorimetric test and it evaluates the compatibility antigen-antibody. The development of a portable device and low cost that it is allows analyzing the ELISA plate (“in situ”). It will suppose one immediately identification of the disease and therefore a faster performance ...

importance of covalent bonded two-dimensional monolayer nanostructures and also hydrocarbons is undeniably responsible for creation of new fascinating materials like polyphenylene polymer, a hydrocarbon super honeycomb network, so-called porous graphene. the mechanical properties of porous graphene such as its young’s modulus, poisson’s ratio and the bulk modulus as the determinative properties...

This study was a comparative evaluation of the bending resistance of metallic and resorbable plates and screws in a mandibular body fracture model. Forty polyurethane synthetic hemimandibles were used; a vertical linear cut was made between the second and first premolars. These 40 hemimandibles were divided into four groups of 10 and were fixed with titanium plates and screws or resorbable plat...

The non-retarded Casimir interaction (van der Waals interaction) between two free standing graphene sheets as well as between a graphene sheet and a substrate is determined. We present several different derivations of the interaction. An exact analytical expression is given for the dielectric function of graphene along the imaginary frequency axis within the random phase approximation for arbit...

Owing to their applications in devices such as electromechanical sensors, actuators and nanogenerators, the consideration of size-dependent properties response composites is great importance. In this study, a closed-form solution based on linear piezoelectricity, Kirchhoff’s plate theory Navier’s was developed, envisage behaviors hybrid graphene-reinforced piezoelectric composite (GRPC) plates,...

direct electron transferring of glucose oxidase was investigated   on reduced graphene and graphene oxide templates. the direct electrochemistry   glucose oxidase on   graphene showed a cyclic voltammograms corresponding to the fad/fadh 2   redox couple with an anodic, cathodic and formal potential of -430, -460 and   -445 mv, respectively in 0.1 m phosphate buffer solution and air saturated   ...

We propose Green functions scattering method to obtain the Casimir–Polder potential between anisotropic atom and one or two planar parallel plates. Lifshitz formula for pressure dielectric half-spaces separated by a vacuum slit is derived within same method. The also applied known conducting systems including graphene which are overviewed.

graphene-based nanocomposites are newly emerged materials with a wide range of applications such as in supercapacitors electrode. the high conductivity and ability for passing electric current, makes graphene an appropriate new item to be used in cells. electroactive transition metal oxides, owing fast reversible redox pairs, are used to store electrical charge. furthermore, the graphene/nio na...
