Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

VIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

Research on Self‐Identification Technology of Zero‐Value Insulators in Distribution Lines Based on Electroluminescence Effect

High Voltage, EarlyView.
ABSTRACT To address the issue of low detection accuracy for zero‐value insulators in distribution lines, this study proposes a novel method for detecting these insulators based on the electroluminescence effect. Through theoretical analysis and experimentation, it was found that the luminescence intensity of ZnS:Cu electroluminescent material varies ...

Ultrasonic Piezoelectric Nebulization of Propoxur for the Determination by Corona Discharge Ionization Ion Mobility Spectrometry

Analytical Sciences, 2019
Propoxur insecticide as a thermally unstable compound (decomposed at its boiling point) could not be analyzed by traditional sample introduction systems based on the thermal desorption. In this study, an ultrasonic piezoelectric nebulizing injection port was applied for evaporating this compound prior to its determination by corona discharge ionization

Study on the Coupled Effects of High‐Speed Airflow and Charged Sand on Power‐Frequency Discharge Characteristics of Conductor–Tower Gaps in Strong Wind–Sand Environments

High Voltage, EarlyView.
ABSTRACT Strong wind–sand weather in Xinjiang threatens power grid safety by increasing transmission line tripping risks. Existing studies focus on sand polarization but neglect the coupled influence of high‐speed airflow and charged sand on gap discharge characteristics.

Investigation of the Partial Discharge Inception and Flashover With IEC‐Based Comparative Tracking Index Electrodes and Comparison With Homogeneous and Inhomogeneous Electric Fields at Varying Pressures for Aerospace Applications

High Voltage, EarlyView.
ABSTRACT For designing aeronautical components, the creepage distance is usually estimated by considering the pollution level and the dielectric material group as defined by the standard IEC 60664‐1. The material group is expressed by the comparative tracking index (CTI) performed at atmospheric pressure following the standard IEC 60112.

Ion‐Flow Field Modelling of ± 1100 kV Transmission Lines Under Strong‐Wind Scenarios Using the Multiple Relaxation Time Lattice Boltzmann Method

High Voltage, EarlyView.
ABSTRACT To solve the ion‐flow field of ultrahigh‐voltage direct current (UHVDC) transmission lines under strong‐wind scenarios, the multiple relaxation time lattice Boltzmann method (MRT‐LBM) is adopted. Compared with previous ion‐flow studies predominantly based on the single relaxation time LBM, the MRT‐LBM framework provides improved numerical ...
