Excimer laser (XeCl gas with wavelength 308 nm) was used for pretreatment of stainless steel substrates through immediately irradiation with the Excimer laser before initiate the deposition of alumina. The irradiated substrate were characterized using, EDX, SEM and nano-indentation measurements in order to specify the composition and microstructure...

We report on a novel technique of surface texturing of polyethylene terephthalate (PET) foil in the presence of silver nanoparticles (AgNPs). This approach provides a variable surface morphology of PET evenly decorated with AgNPs. Surface texturing occurred in silver nanoparticle colloids of different concentrations under the action of pulse excime...
We investigated the complex interaction between a nickel layer and a 4H-SiC substrate under UV-laser irradiation since the early stages of the atomic inter-diffusion. An exhaustive description is still lacking in the literature. A multimethod approach based on Transmission Electron Microscopy, Energy Dispersive Spectroscopy and Diffraction (electro...
The technique for precise measurements of wavelengths in the range around 222 nm (45030 cm–1) has been presented. The reciprocal linear dispersion of the spectrometer was 0.529 Å/mm. The measurements were made in the second spectral order for a grating with 2400 lines/mm. Identification of emission lines of hollow cathode lamp (Fe) was made in the...
