“…It is widely known that materials containing silver may have the most promising antibacterial behavior against some bacteria [1][2][3]. When Ag atoms transform into ions and enter the environment, the multiplication of bacteria may be stopped, probably due to their engagement with bacteria's DNA structure [4].…”

Protective corrosion resistant coatings serve for decreasing the amount of ionic contaminants from Havar ® entrance foils of the targets for [ 18 F] production. The corrosion damage of coated entrance foils is caused mainly by the diffusion of highly reactive products of water radiolysis through the protective film towards Havar ® substrate. Since amorphous metal alloys (metallic glasses) are well-known to perform a high corrosion resistance, the glass forming ability, microstructure and diffusion barrier efficiency of binary alloys containing chemically inert Nb, Ta, Zr were investigated. Nb-Ta, Nb-Zr and Ta-Zr films of different alloy composition and ~1.5 μm thickness were co-deposited by magnetron sputtering. Diffusion barrier efficiency tests used reactive aluminum underlayer and protons of acid solution and gallium atoms at elevated temperature as diffusing particles. Though cosputtered Nb-Ta and Nb-Zr alloy films of different contents were crystalline, Ta-Zr alloy was found to form dense amorphous microstructures in a range of composition with 30-73% atomic Ta. The diffusion barrier efficiency of Nb-Zr and Nb-Ta alloy coatings decreased with increase of Nb content. The diffusion barrier efficiency of sputtered Ta-Zr alloy coatings increased with the transition from nanocrystalline columnar microstructure to amorphous for coatings with 30-73% at. Ta.
