We analyze in which experimental conditions the concept of electrical impedance is useful for an electrolytic cell. The analysis is performed by solving numerically the differential equations governing the phenomenon of the redistribution of the ions in the presence of an external electric field and comparing the results with the ones obtained by solving the linear approximation of these equati...

the objective of this research is to represent applicability of surface nuclear magnetic resonance (snmr) in aquifer characterization, based on snmr and electrical resistivity tomography data. snmr is the only geophysical method that directly detects water. two important parameters, porosity and permeability are available through inversion of initial amplitude and decay time constant versus pul...

The emergence of graphene with its unique electrical properties has triggered hopes in the electronic devices community regarding its exploitation as a channel material in field effect transistors. Graphene is especially promising for devices working at frequencies in the 100 GHz range. So far, graphene field effect transistors (GFETs) have shown cutoff frequencies up to 300 GHz, while exhibiti...

Cu thin films have been deposited on Si (100) substrate by using a non-mass-separated ion beam deposition (IBD) system. The effect of the substrate bias voltage on the properties of the deposited films was investigated using X-ray diffraction, resistivity measurement and field emission scanning electron microscopy. In the case of Cu thin films deposited without bias voltage, a columnar structur...

Cell fusion is induced between guard cell and mesophyll cell protoplasts of Vicia faba by electrical field application. The process of fusion is initiated by electrical breakdown of the cell membrane. Prior to the application of an external electrical field pulse which brings about reversible breakdown of the membrane, the cells (suspended in a low-conducting medium) are brought into close cont...

PURPOSE To document the incidence and outcome of flash burns due to electrical switchboard explosions presenting to Concord Hospital Burns Unit, from January 2000 to December 2008. METHODS The Concord Hospital Burns Unit Database was reviewed for admissions due to electrical burns from January 2000 to December 2008. RESULTS There were 119 electrical burns admitted during the study period, 2...

Duplex capillary columns with a packed and an open section are widely used in electrochromatography (CEC). The duplex column configuration leads to non-uniform voltage drop, electrical field distribution and separation performance. It also adds to the complexity in understanding and optimizing electrochromatographic process. In this study, we introduced a simplex column configuration based on s...
