We report on the coating with ZnO adherent thin fi lms of cotton woven fabrics by Pulsed laser deposition technique in order to obtain innovative textile materials, presenting protective effects against UV radiations and antifungal action.
Read moreWe manufactured antifungi textile materials by treating them with zinc oxide and hydrophobine micro and nano structures. The zinc oxide was applied as thin layers by pulsed laser deposition while the hydrophobine expanded on the textile following impregnation. Both zinc oxide and hydrophobines entirely covered the fibers. The antifungi nature of the treated materials was studied using the Aspergillus niger IMI 45551 cultures.
Read moreWe report on the versatility of pulsed laser deposition and radio frequency magnetron sputtering deposition methods to synthesize highly adherent bioactive hydroxyapatite thin layers on cranio-pinal implants as appropriate biofixation alternatives.
Read moreCotton/polyester woven fabrics were functionalized with ZnO thin films or nanoparticles by pulsed laser deposition, using a KrF* excimer laser source. Depending on the number of applied laser pulses, well-separated nanoparticles (for 10 pulses) or compact thin films (for 100 pulses) were deposited. The synthesized nanostructures were evaluated morphologically by scanning electron microscopy and atomic force microscopy, physico-chemically by x-ray
Read moreNanometer polyethylene (PE) thin films were prepared by Matrix Assisted Pulsed Laser Evaporation (MAPLE). Insulating PE thin films of different thicknesses, below 200 nm, were fabricated by varying the deposition conditions. We then used the Differential Evanescent Light Intensity (DELI) microscopy technique for thickness profiles investigation of the PE nanolayers together with AFM measurements for calibration. A phenomenological model for the interaction
Read moreIndium Zinc Oxide compositional libraries were fabricated by combinatorial pulsed laser deposition technique on glass substrate at room temperature. Two pairs of targets with In atomic concentrations, In/(In+Zn), of 28 at.% and 56 at.% or 42 at.% and 70 at.% were employed. A high transparency was observed for all the coatings with transmittance values better than 95%. The maximum thicknesses of the samples, inferred by spectroscopic ellipsometry,
