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.

Valorizing Erasure: Imperial Knowledge Production in Anglo‐American Coverage of Chad's ‘Toyota War’
The British Journal of Sociology, EarlyView.ABSTRACT How does imperial knowledge production operate when Western media coverage of a Global South subject is predominantly admiring instead of hostile? This article addresses that question through critical discourse analysis of sixty‐three Anglo‐American news articles covering the Chad‐Libya conflict of the 1980s, the ‘Toyota War’.
