New Findings from University of Belgrade in Ozone Provides New Insights (Effect of UV/ozone treatment on the nanoscale surface properties of gold implanted polyethylene)

By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Ozone. According to news reporting out of Belgrade, Serbia, by NewsRx editors, research stated, "The effect of ultraviolet (UV) ozone treatment on the surface properties of gold implanted high density polyethylene (HDPE) was investigated at a nanoscale using Atomic Force Microscopy (AFM). HDPE samples were modified by the implantation of gold ions at a dose of 5 x 10(15) ions/cm(2), using energies of 50, 100, 150, and 200 keV, and subsequently treated with UV/ozone."

Our news journalists obtained a quote from the research from the University of Belgrade, "AFM surface topography images revealed that after UV/ozone treatment, the surface roughness of all Au/HDPE samples increased, while Power Spectral Density function increased only for samples implanted using higher energies, with a maximum for 150 keV. The chemical surface composition was homogenous in all cases, which was evidenced by appearance of single peaks in the histograms obtained from the phase AFM images. For UV/ozone treated samples, the shift of the peaks positions in the histograms to the higher values of the phase lag with respect to untreated ones indicated the decrease of surface hardness."

According to the news editors, the research concluded: "Besides, a significant change of fractal dimension of surface grains is observed after UV/ozone treatment."
