Specific structural changes in Sc/Si multilayer mirrors irradiated with extreme ultraviolet (EUV) laser single pulses (λ = 46.9 nm) at near damage threshold fluences (0.04–0.23 J cm−2) are analysed. We have identified melting of surface layers as the basic degradation mechanism for the mirrors. Both heat generation during silicide formation and low heat conduction of the layered system signific...
Objective: Surface coating of dental mirrors using nanotechnology has been done to render them self-cleaning properties. Nano-scaled titanium dioxide particles (TiO2)show antimicrobial properties when exposed to ultra-violet (UV) light. The aim of this study was to evaluate the effect of surface coating of dental mirrors with nano titanium dioxide on their self-cleaning (from dentists’ perspe...
