Performance of Corona Resistant Insulation for Aerospace

open access: yes, 2021
Impulse voltage waveforms from power converters enhance the voltage stress on the turn insulation system of rotating machines. When the voltage stress exceeds a critical level, partial discharges can be incepted leading to premature failure of the ...

Performance Analysis of Polypropylene Material on Thermal Insulation Effect of Cement External Wall

open access: yesChemical Engineering Transactions, 2017
In order to solve the shortcomings of the traditional organic thermal insulation material, the ordinary portland cement is modified firstly. Although organic insulation material is lighter in texture and better in thermal insulation, it is very flammable.

Modeling of Organic Metal–Insulator– Semiconductor Capacitor [PDF]

open access: yesIEEE Transactions on Electron Devices, 2019
In this paper, we demonstrate the principle of operation of a metal-insulator-semiconductor (MIS) capacitor based on undoped organic semiconductor. In spite of low charge concentration within the semiconductor, this device exhibits a capacitance variation with respect to applied gate voltage $V_g$, resembling the capacitance-voltage $C$-$V ...

We gather together: insulators and genome organization [PDF]

open access: yesCurrent Opinion in Genetics & Development, 2007
When placed between an enhancer and promoter, certain DNA sequence elements inhibit enhancer-stimulated gene expression. The best characterized of these enhancer-blocking insulators, gypsy in Drosophila and the CTCF-binding element in vertebrates and flies, stabilize contacts between distant genomic regulatory sites leading to the formation of loop ...
