The main difference between electric current and static electricity is that the electrons or charges flow through the conductor in an electric current. Whereas, in static electricity, the charges are rest and accumulated on the surface of the substance. The electric current is due to the flow ...

High-resolution SEM analysis showed that bonding under the influence of electricity reduced interfacial nanoleakage. It is speculated that resin infiltration may be improved by the attraction of polar monomers by an electric current or by modification of the dentin surface charges, resulting in better...
In this study, an underwater wireless communication via Maxwell’s displacement current, ∂P/∂t, is proposed. The TENG that converts sound to electricity is connected to a transmitting electrode to generate the time-varying polarization electric field underwater. The corresponding time-varying ...

Research finds that students have many ideas on electricity not aligned with scientific notions (e.g. Eylon & Ganiel, 1990; Thacker, Ganiel, & Boys, 1999; Osborne, 1983; Shen, Gibbons, Wiegers, & McMahon, 2007; Shepardson & Moje, 1994). It is challenging to change these conceptions. Diff...

The asymmetric surface functionalization of the electrodes is playing an important role in the significantly improved mechanoionic electricity generation. Specifically, maximum output is achieved only if differential ion adsorption properties of electrodes are in accordance with the differential ion diffusion ...
Figure 3 pictures the electrochemical devices used for photo electricity measurements in up to 12 parallel channels. The devices were 3D-printed to allow for a compact, shareable design and to enable temperature control via hollow walls and a circulating water bath. The structured anodes on FTO-gl...
