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.

An Overview of High‐Temperature Superconducting Cables in DC Systems: Unlocking Potential for High‐Voltage DC Networks

High Voltage, EarlyView.
ABSTRACT This paper provides an overview of high‐temperature superconducting (HTS) cables in DC systems, with a focus on their deployment in high‐voltage DC (HVDC) networks. The assessment of HTS cable properties—such as extremely low electrical resistance, high current‐carrying capacity and a compact geometry—and their comparison with those of ...

Design and performance of a capacitor‐based burn‐through monitor for high‐power X‐ray beams at XFEL facilities

Journal of Synchrotron Radiation, EarlyView.
We present the results of testing 92 prototypes of a capacitor‐based burn‐through monitor at the LCLS XCS and XPP endstations. We quantify the beam energy density thresholds required to induce a detectable high‐voltage electrical short prior to complete burn‐through and demonstrate the reliability of this scalable, low‐cost solution for machine and ...
