Nanosized metal oxide halogen adducts possess high surface reactivities due to their unique surface morphologies. These adducts have been used as reactive materials against vegetative cells, such as Escherichia coli as well as bacterial endospores, i

Composite nanostructured samples of Ag (0.5-20%)/(C, S)-TiO(2) were synthesized and characterized by EDX, XRD, FT-IR, UV-vis, BET, XPS, and zeta potential measurements. Photocatalytic and biocidal tests revealed that the amount of the codoped silver

Although evidence to date indicates that reprocessing electrophysiological (EP) catheters results in clean, sterile devices, some concerns persist with regard to the risk of residual contamination. We examined the ability of a defined reprocessing pr

Bacterial pollution of water is impacted to a great extent by the ability of bacteria to survive in manure following excretion. We investigated the effects of environmental temperature (4°C, 27°C, and 41°C) and manure moisture content (30%, 55%, a

Certain formulations of nanoscale powders possess antimicrobial properties. These formulations are made of simple, nontoxic metal oxides such as magnesium oxide (MgO) and calcium oxide (CaO, lime) in nanocrystalline form, carrying active forms of hal

Selected metal oxide nanoparticles are capable of strongly adsorbing large amounts of halogens (Cl(2), Br, I(2)) and mixed halogens. These solid adducts are relatively stable thermally, and they can be stored for long periods. However, in the open en
