Simultaneous Photocatalytic Reduction of Cr(VI) and Oxidation of Benzoic Acid in Aqueous N-F-Codoped TiO2 Suspensions: Optimization and Modeling Using the Response Surface Methodol...
Published 2012-01-01“…The removal of Cr(VI) and BA in binary systems, containing both Cr(VI) and BA, showed a synergistic photocatalytic decontamination as BA significantly facilitated Cr(VI) reduction, whereas Cr(VI) accelerated also BA degradation. Due to the anionic-type adsorption onto TiO2 and its acid-catalyzed photocatalytic reduction, the removal of Cr(VI) decreased with increasing pH, while the degradation of BA followed also the same trend. …”

Escherichia coli stress response systems and their reaction to terahertz radiation
Published 2017-02-01“…The obtained data indicate that exposure to nonthermal terahertz radiation induces E. сoli gene networks of oxidative stress and copper ion homeostasis, but does not activate those responding to antibiotics, protonophores, or superoxide anions. The fact that E. сoli/pKatG-GFP and E. сoli/pCopA-GFP biosensors have different activation and reaction periods when exposed to terahertz radiation and natural inducers suggests that reactions of oxidative stress and copper ion homeostasis systems to terahertz radiation are specific.…”
