A model for the electrostatic interactions in water in the vicinity of a surface is suggested, which accounts, within the Poisson-Boltzmann mean field approach, for the screening of the charges and for the coupling interactions between neighboring dipoles. When the water molecules near a solid surface are assumed to be organized in icelike layers, the polarization is not a continuous function b...

Finite element analysis procedures are utilized to provide theoretical calibration curves for the electrical potential crack-monitoring system as applied to single-edge-notch (SEN) and compact tension (CT) fracture specimens. The results are compared to existing calibrations for such test piece geometries derived using experimental, electrical analog and analytical (conformal mapping) procedures.

We investigate the electrokinetic flow and transport within a micro-electrophoresis device. A mathematical model is set up, which allows to perform two-dimensional, time-dependent finite-element simulations. The model reflects the dominant features of the system, namely electroosmosis, electrophoresis, externally-applied electrical potentials, and equilibrium chemistry. For the solution of the ...

Two-dimensional layered semiconductors present a promising material platform for band-to-band-tunneling devices given their homogeneous band edge steepness due to their atomically flat thickness. Here, we experimentally demonstrate interlayer band-to-band tunneling in vertical MoS2/WSe2 van der Waals (vdW) heterostructures using a dual-gate device architecture. The electric potential and carrie...

Electromyography is the recording and analysis of the electrical potentials of the muscle. Man has always been curious to know about his body and the surroundings. This led the mankind through many path breaking inventions that made human life easy. Much research has been done and documented in the field of bioelectricity which led to the present day electrodiagnostic procedures. .EMG as a diag...

in order to restrain the potential of wind energy, the first step is to determine the wind energy potential. in this study the wind data was used from the three-hour frequency recording of 10-year period (2002-2011). to predict the occurrence probability of each wind speed, the two-parameter weibull function was used. the goodness of fit test by chi-square test showed that the wind speed distri...

We present a comparison between the di€erent methods reported in the literature to experimentally determine the electron mobility in the channel of a MOSFET. In order to accurately obtain the mobility for use in an I±V model a suitable determination of inversion charge and electric potential is shown to be relevant. Numerical simulation is demonstrated to be a powerful tool to carry out mobilit...

[1] We present University of Michigan MHD code results of the ‘‘metrics challenge.’’ We have simulated the magnetospheric and ionospheric configuration during the 16–17 April 1999 CME, the 10–11 December 1998 time period, and the 5–6 November 1998 time period. The simulation results were compared to the DMSP cross-track velocities, and the RMS differences were examined. We have found that the c...

Utilizing the integral expression of Coulomb’s Law to determine the electric potential from a continuous charge distribution is a canonical exercise in Electricity and Magnetism (E&M). In this study, we use both think-aloud interviews and responses to traditional exam questions to investigate student difficulties with this topic at the upperdivision level. Leveraging a theoretical framework for...
