Focusing Microwave Radiation for Long-Distance Wireless Power Transfer in Space

open access: yesIEEE Microwave Magazine
Radiative wireless power transfer (WPT) uses freely propagating electromagnetic (EM) radiation for long-distance energy distribution. Microwaves, which are not strongly affected by the atmosphere [1], can be focused into beams for higher efficiencies. Thus, the need for cables and batteries can be reduced, minimizing costs and enabling power supply to ...

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

open access: yesVIEW, 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.
