On the Colloidal Stability of Nitrogen-Rich Carbon Nanodots Aqueous Dispersions

C, 2019
The present survey reports on the colloidal stability of aqueous dispersions of nitrogen-rich carbon nanodots (N-CDs). The N-CDs were synthesized by thermally induced decomposition of organic precursors and present an inner core constituted of a ...

Unraveling the “U-Shaped” Dependence of Surface Flashover Performance on the Surface Trap Level

IEEE Access, 2019
The effects of surface traps on surface flashover remain controversial. To clarify the relation between surface flashover and surface trap level, in this work, the surface trap level of epoxy composites was modified by nanoparticles incorporation ...

The charge of glass and silica surfaces [PDF]

The Journal of Chemical Physics, 2001
We present a method of calculating the electric charge density of glass and silica surfaces in contact with aqueous electrolytes for two cases of practical relevance that are not amenable to standard techniques: surfaces of low specific area at low ionic strength and surfaces interacting strongly with a second anionic surface.

Surface Charge and Electric Field Distribution of Direct-Current Gas-Insulated Transmission Lines’ Basin-Type Insulators Under Multi-Field Coupling

Applied Sciences
In direct-current gas-insulated transmission lines (DC GIL), complex heat transfer processes accelerate surface charge accumulation on insulators, causing local electric field distortion and elevating the risk of surface flashover.
