High stability gel electrolytes for long life lithium ion solid state supercapacitor [PDF]

open access: yesE3S Web of Conferences, 2021
Lithium ion capacitors with liquid electrolyte are prone to leakage, combustion, explosion and other dangerous accidents. To solve these problems, the solid gel separator prepared by polyvinylidene fluoride - six fluoropropene (PVDF-HFP) is used in this ...

The role of low air pressure in the variation of negative corona-generated space charge in a rod to plane electrode

open access: yesHigh Voltage, 2018
The corona-generated space charge may vary in different air pressures, and the quantitative law between the corona-generated space charge density and air pressure has never been investigated.

Ion Channel Trafficking: Control of Ion Channel Density as a Target for Arrhythmias?

open access: yesFrontiers in Physiology, 2017
The shape of the cardiac action potential (AP) is determined by the contributions of numerous ion channels. Any dysfunction in the proper function or expression of these ion channels can result in a change in effective refractory period (ERP) and lead to

Disturbance in the Daytime Midlatitude Upper F Region Associated with a Medium Scale Electrodynamic Vortex Motion of Plasma [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2016
Under the assumption of the presence of a medium-scale E × B drift vortex of plasma in the daytime midlatitude F region, and using a simplified ionospheric model, we demonstrate that the E × B drift produces noticeable perturbations in the horizontal ...
