"Reversed" alamethicin conductance in lipid bilayers

open access: yesBiophysical Journal, 1991
Alamethicin at a concentration of 2 micrograms/ml on one side of a lipid bilayer, formed at the tip of a patch clamp pipette from diphytanoyl phosphatidylcholine and cholesterol (2:1 mol ratio) in aqueous 0.5 M KCl, 5 mM Hepes, pH 7.0, exhibits an asymmetric current-voltage curve, only yielding alamethicin currents when the side to which the peptide ...

A Three-Level GaN Driver for High False Turn-ON Tolerance With Minimal Reverse Conduction Loss

open access: yesIEEE Open Journal of Power Electronics, 2023
This paper presents a three-level gate driver for GaN HEMTs (Gallium Nitride High Electron Mobility Transistors) for high false turn-on tolerance and low reverse conduction loss during both dead time at turn-on and turn-off.

On the effect of nano-injectors on conduction in silicon p-i-n diodes [PDF]

open access: yes, 2010
P–i–n diodes are widely used in power electronics [1-2], solar cells [3], light detection [4] and also light generation [5]. Contrary to the case of light detection or conversion, light generation is usually achieved by biasing the device in forward mode,

Recovery of complete left bundle branch block in dilated cardiomyopathy after optimal heart failure treatment: a case report [PDF]

open access: yesJournal of Medicine and Life Science
Complete left bundle branch block (CLBBB) is a significant cardiac conduction abnormality often associated with dilated cardiomyopathy (DCM). This case report highlights the improvement in CLBBB and symptom relief through reverse cardiac remodeling in a ...

Investigation of Dead Time Losses in Inverter Switching Leg Operation: GaN FET vs. MOSFET Comparison

open access: yesEnergies
This paper investigates the commutation transients of MOSFET and GaN FET devices in motor drive applications during hard-switching and soft-switching commutations at dead time operation. This study compares the switching behaviors of MOSFETs and GaN FETs,

Characterization and optimization of active negative voltage driving circuit for CoolGaN HEMTs in a phase-leg configuration

open access: yesEnergy Reports, 2022
The high switching speed of GaN HEMT will cause serious crosstalk in the phase-leg configuration. The negative turn-off driving voltage is usually recommended to avoid the parasitic shoot-through.
