Electrical Conductivity Across Line Defects on the Si(111)-7×7 Surface

Electrical Conductivity near the Earth’s Surface: Ion – Aerosol Model

An ion-aerosol model for the electrical conductivity of the lower atmosphere is developed. Input parameters to the model are ion-pair production rate, obtained from the concentrations of radon and its progeny; aerosol number density; and the meteorological parameters such as temperature, pressure and relative humidity are the input parameters to the model. Diurnal values of conductivity compute...

Conductivity of epitaxial and CVD graphene with correlated line defects

On-line Classification of Surface Defects in Hot Rolling Processes

This paper develops a methodology for the online classification of different types of surface defects in rolling processes. The method developed consists of three major steps: feature generation, feature selection, and classifier design. Based on the engineering knowledge of rolling processes, a set of potential features are generated from the local regions of sensing images that contain the su...

Electrical conductivity of CuO nanofluids

An empirical electrical conductivity assessment of nanofluids comprising CuO nanoparticles water-based in different concentrations, particles size and various temperatures of nanofluids has been carried out in this paper. These experimentations have been done in deionized water with nanoparticles sizes such as 89, 95, 100 and 112 nm and concentrations of 0.12 g/l, 0.14 g/l, 0.16 g/l and 0.18 g/...

Effect of structural defects on the thermal conductivity of graphene: From point to line defects to haeckelites

We use nonequilibrium molecular-dynamics simulations to study the effect of structural defects on the thermal conductivity λ of graphene. Focusing on 5-7 and 5-8 defects in the graphene honeycomb lattice, we find that λ depends sensitively on whether the defects are isolated, form lines, or form extended arrangements in haeckelites. Our results indicate that the presence of defects makes λ anis...
