New Physics Research Data Have Been Reported by Investigators at Dublin City University [Polycarbonate Polymer Surface Modification by Extreme Ultraviolet (EUV) Radiation]

By a News Reporter-Staff News Editor at Physics Week -- Current study results on Physics Research have been published. According to news reporting originating in Dublin, Ireland, by VerticalNews journalists, research stated, "The degree of the biocompatibility of polycarbonate (PC) polymer used as biomaterial can be controlled by surface modification for various biomedical engineering applications. In the past, PC samples were treated by excimer laser for surface reorganization however associated process alteration of bulk properties is reported."

The news reporters obtained a quote from the research from Dublin City University, "Extreme ultraviolet radiation can be employed in order to avoid bulk material alteration due to its limited penetration. In this study, a 10 Hz laser-plasma EUV source based on a double-stream gas-puff target irradiated with a 3 ns and 0.8 J Nd:YAG laser pulse was used to irradiate PC samples. The PC samples were irradiated with different number of EUV shots. Pristine and EUV treated samples were investigated by scanning electron microscopy and atomic force microscopy for detailed morphological characterization of micropatterns introduced by the EUV irradiation. Associated chemical modifications were investigated by X-ray photoelectron spectroscopy."

According to the news reporters, the research concluded: "Pronounced wall-type micro- and nanostructures appeared on the EUV modified surface resulting in a change of surface roughness and wettability."
