Ferromagnetic‐Based Charge‐Accumulation Triboelectric Nanogenerator With Ultrahigh Surface Charge Density

Small, 2022
AbstractAn encouraging micro‐energy harvesting technology, the triboelectric nanogenerator (TENG), has been proven to transfer ambient environmental micro‐energy into electricity, but a low surface charge density results in low performance and limits the practical application of TENG.

A review on factors that affect surface charge accumulation and charge-induced surface flashover

Nanotechnology, 2021
Abstract The surface charge accumulation is very likely to trigger the surface flashover, which limits the large-scale application of DC GIL/GIS. This article comprehensively reviews the effect of six factors, including insulator-electrode shape, surface roughness of the insulator and conductor, metal particles, temperature, humidity,

Charge Accumulation at InAs Surfaces

Physical Review Letters, 1996
Angle-resolved photoelectron spectroscopy has been used to directly prove the existence of a charge accumulation layer at clean InAs surfaces. The formation of an accumulation layer is shown to be a common property of polar InAs surfaces, with the precise surface Fermi level position above the conduction band minimum determined by the surface geometry.

Surface-Charge-Dependent Nanoparticles Accumulation in Inflamed Skin

Journal of Pharmaceutical Sciences, 2012
Polymeric nanoparticles (NPs) are interesting drug carriers for dermal application and drug targeting to certain skin structures. NP interactions with diseased skin and the associated benefits and risks have been hardly explored. Today, we study the behavior of polymeric NPs for selective drug delivery to inflamed skin.

Single filament partial discharge: Surface charge accumulation

2013 Annual Report Conference on Electrical Insulation and Dielectric Phenomena, 2013
In our experiments the single DC discharges propagate in the “needle - air gap - dielectric barrier - plane” system under atmospheric pressure. Polypropylene (12 μm) and polyethylene terephthalate (100 μm) films were used as barriers. Interelectrode air gap varied in the range of 100-2000 μm, breakdown voltages - in the range of 1200-3800 V.

Surface charge accumulation and decay in electrospray printing

Journal of Physics D: Applied Physics, 2020
Abstract In electrospray printing, the accumulation of electric charge on the target substrate plays an important role in governing the structure of the deposit. To better understand the effect of charge, we report on the use of two methods to measure the rate of charge accumulation and decay on dielectric substrates targeted with ...

Surface-charge accumulation and clustering in fluorites

Solid State Ionics, 1983
Abstract Comparative Thermally Stimulated Polarization and Depolarization studies have been carried out on SrF 2 crystals doped with lanthanum up to molar concentrations of 5x10 −2 and to temperatures of 500K. The first three peaks, attributed to nearest-neighbour dipoles and to clusters built with this basic unit (L-shaped La 3+ -F i2 − and the ...

Insulator surface charge accumulation under impulse voltage

IEEE Transactions on Dielectrics and Electrical Insulation, 2004
The surface charge distribution under impulse voltage is measured using a static capacitance probe. A probe with very small charge leakage is designed. The condition of surface charge accumulation under impulse voltage is analyzed, and it is concluded that micro discharges in the gas near the insulator surface such as the corona caused by free and ...
