Using Hyperspectral Imaging to Quantify Phototrophic Biofilms on Granite
(International Society for Environmental Information Sciences, 2020-03)
[Abstract]: This paper reports a non-invasive method for in situ biofilm quantification based on the use of hyperspectral imaging to analyze a chromatically and texturally heterogeneous substrate as granite colonized by ...
Enhancement of graffiti removal from heritage stone by combining laser ablation and application of a solvent mixture
(Elsevier, 2020-11)
[Abstract] In this study, it was evaluated the combined cleaning treatment based on laser ablation followed by the application of chemical products for removing alkyd graffiti paint from two different types of stone. Three ...
Development of processing strategies for 3D controlled laser ablation: Application to the cleaning of stonework surfaces
(Elsevier, 2020-03)
[Abstract] Laser cleaning is an environmentally friendly method based on laser ablation processes to remove impurities or contaminants from a surface layer of a material. The configuration of a laser station in the case ...
Surface Modification of Porous Titanium Discs Using Femtosecond Laser Structuring
(MDPI, 2020-06)
[Abstract] The failure of titanium implants is associated with two main problems that include the bone resorption and fracture of the surrounding bone tissue (stiffness incompatibility) and implant loosening (poor ...
