We report a study of the optical and electric properties of Au nanoparticle networks grown on the porous alumina membrane by dry atom sputtering deposition approach. An effective cluster model was developed to evaluate the dielectric function and the electrical conductivities of the nanoparticle networks by taking into account the effects of the Au particle size, the Au volume fraction, and the...

The steady-state zero output of static electric field measuring systems often fluctuates, which is caused mainly by the finite leakage resistance of the water film on the surface of the electric field microsensor package. The water adsorption has been calculated using the Boltzmann distribution equation at various relative humidities for borosilicate glass and polytetrafluoroethylene surfaces. ...

We report low-temperature, high-field magnetotransport measurements of SrTiO(3) gated by an ionic gel electrolyte. A saturating resistance upturn and negative magnetoresistance that signal the emergence of the Kondo effect appear for higher applied gate voltages. This observation, enabled by the wide tunability of the ionic gel-applied electric field, promotes the interpretation of the electric...

Traditional knitted fabrics have been extensively applied in dresses and home decoration, and in recent years, the applications of the fabrics knitted by new technologies and new materials also increase in other fields. The conductive fiber knitted fabrics was used in the article, and its electric properties under transverse stretching were tested and researched. Based on the electric model of ...

For high-mobility two-dimensional electrons at a GaAs/AlGaAs heterojunction, we have studied, both experimentally and theoretically, the recently discovered giant magnetoresistance oscillations with nearly zero resistance in the oscillation minima which appear under microwave radiation. We have proposed a model based on nonequilibrium occupation of Landau levels caused by radiation which descri...

The Several animal models have been proposed for resistance training. In addition, the results of these studies have been highly variable. Some of the studies have used negative reinforcement, electric shock or food deprivation to motivate the learning of the task. Features such as conditioning through electric shock may undermine the significance of the results or even prevent the model from b...

Electric tields can mtluence the fracture toughness offerroelectrics. For example, poled ferroelectrrcs cxhtbit fracture toughness anisotropy : the material is tougher for a crack parallel to the poling direction but less tough for a crack perpendicular to it. When an electric field is applied to a poled sample. a positive field reduces its fracture toughness but a negative field enhances it. P...

PURPOSE To explore the experiences of using an electric wheelchair in daily living. METHODS Fifteen participants, eight women and seven men, living in different parts of a Nordic country were interviewed. The interviews were conducted in the home or at the workplace. Open-ended questions were used. The data were collected and analyzed according to the grounded theory. RESULTS Analysis resul...
