Cost-Benefit Analysis of Nano Coating on Ceramic Insulators on Leakage Current Characteristics

open access: yesIndonesian Journal of Innovation and Applied Sciences
Ceramic insulator components have high popularity because the majority of electrical distribution systems in Indonesia use ceramic insulators. Ceramic insulators have advantages in mechanical strength, but the nature of the surface material makes it easy

USF binding sequences from the HS4 insulator element impose early replication timing on a vertebrate replicator [PDF]

open access: yes, 2012
The nuclear genomes of vertebrates show a highly organized program of DNA replication where GC-rich isochores are replicated early in S-phase, while AT-rich isochores are late replicating.

Harmonic Generation in Metal-Insulator and Metal-Insulator-Metal Nanostructures

open access: yes, 2018
We report that the second and third harmonic signal reductions with insulator film surface coverage over a gold substrate gives a measure of the electron density in the spill out volume of the insulator, which is dubbed metal insulator gap states.
