  • The use of reduced sulfur compounds as electron donors for biological denitrification has the potential to reduce chemical and sludge disposal costs as well as carry-over of organic carbon to the effluent that often occurs with heterotrophic denitrification. (environmental-expert.com)
  • High levels of volatile organic sulfur compounds (VOSCs) have frequently been detected during algae-induced black blooms, which pose an ecological threat to water bodies and their surrounding residents. (environmental-expert.com)

  • chemical
  • The superior electrochemical performances of TG/S could be ascribed to the synergistic effects between the conductive rGO support and the physically/chemically absorptive TiO 2 , that is, the spatial tubular structure of TiO 2 provides intimate contact and physical confinement for sulfur, while the polar TiO 2 in TG/S shows strong chemical interaction towards the sulfur species.

  • Moreover, the TG/S composite cathode shows stable Coulombic efficiencies of over ~95% at various C rates, which are ~10% higher than those of the rGO/sulfur (G/S) counterparts. (osti.gov)
