  • Non-thermal plasma (NTP) technology is regarded as promising method for abatement of volatile organic compounds (VOCs) and has gained substantial interests in the fields of air purification. In this present work at atmospheric pressure, dielectric barrier discharge (DBD) plasma has been employed and utilized to evaluate feasibility of toluene, benzene, and m-xylene degradation in a parallel plate type DBD reactor taking argon as a carrier gas.

  • Smart hydrogels comprising carboxymethyl guar gum and polyvinyl alcohol (CMGG/ PVA) were fabricated using tetraethyl orthosilicate as crosslinker. The hydrogels were subjected to nonthermal plasma (NTP) treatment using nitrogen and ammonia mixture. The hydrogels displayed higher swellability in intestinal pH than gastric pH. Appreciable biofilm eradication features against E. coli were observed from the NTP-modified hydrogels. Hemolytic assessment confirmed their compatibility with human blood cells.
