The optical properties and thermal conductivity of carbon nanotubes in the presence of Nitrogen doping and electric field investigated via the Green's function method and tight binding approximation. The doping and external fields lead to modifications in the density of state (DOS), optical properties, electrical and thermal conductivity. The band gap decreases by the electric field until reach...

Magnetic resonance electrical impedance tomography (MREIT) is a recently developed imaging technique that combines MRI and electrical impedance tomography (EIT). In MREIT, cross-sectional electrical conductivity images are reconstructed from the internal magnetic field density data produced inside an electrically conducting object when an electrical current is injected into the object. In this ...

The effects of field strength and multiple thermal treatments on electrical conductivity of strawberry products were investigated. Electrical conductivity increased with temperature for all the products and conditions tested following linear relations. Electrical conductivity was found to depend on the strawberry-based product. An increase of electrical conductivity with field strength was obvi...

Rolling element bearings are required to operate in a variety of use cases that determine voltage potentials will form between the rolling elements and races. When electrical field strength causes dielectric breakdown intermediary lubricant film discharge can damage bearing surfaces. To reduce prevalence severity machining an improved understanding coupled mechanical behavior is necessary. This...

Fluorescence imaging provides a comprehensive view of the electrical behavior of excitable cells, the relative nature of the optical signals however requires additional means for calibration. The determination of the actual electrical field strength is subject to uncertainty even when using concurrent electrode measurements. A combined approach of electrical field measurement and optical mappin...
