Impact of Pollution Location on Time and Frequency Characteristics of Leakage Current of Porcelain Insulator String under Different Humidity and Contamination Severity [PDF]
Journal of Operation and Automation in Power Engineering, 2007 One of the important factors influencing outdoor insulators performance is pollution phenomenon. The pollution, especially during humidity condition, reduces superficial resistance of insulator and lead to a flow of Leakage Currents (LC) on the insulator

Study on surface leakage current at sidewall in InP-based avalanche photodiodes with mesa structure
AIP Advances, 2022 A multi-mesa InGaAs/InP avalanche photodiode (APD) with the advantage of the completely restricted electric field is proposed. The surface defects, which are the reasons for the sidewall leakage current generation in the mesa-structure APD, are ...

Temperature Dependence of Electron Leakage Current in InGaN Blue Light-Emitting Diode Structures
Nanomaterials, 2022 We investigated the temperature dependence of the electron leakage current in the AlGaN electron-blocking layer (EBL) of an InGaN/GaN blue light-emitting diode (LED) structure at temperatures between 20 and 100 °C.

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9
FEBS Letters, EarlyView.Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...
