AbstractHigh-grade disinfection was investigated in high-density ozone excited by a dielectric barrier discharge. The experimental result indicated complete disinfections of Bacillus atrophaeus, a spore forming bacterium and Aspergillus niger, Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus and Candida albicans have been achieved for the surface exposed high density ozone on metallic career with smooth surface or Exafine, a type of hydrophilic vinyl polysiloxane impression material with complex surface.

AbstractMetal oxides of titanium, vanadium, manganese and iron were deposited on the native Jordanian diatomaceous clay. The chemical and structural properties of the prepared samples were investigated using SEM, XRF, ICP, XRD and FTIR techniques. The diatomaceous clay supported metal oxides were used in preliminary experiments to explore their interaction with aqueous phenol solution under thermal and photochemical conditions, in the presence and absence of hydrogen peroxide. The results showed that the metal oxides have interacted with the diatomaceous clay and caused some structural changes. These were reflected in the surface area of the samples and their activity in the phenol reactions.
