Dual Combination of Cleaning Methods (Scalpel, Biocide, Laser) To Enhance Lichen Removal From Granite
[Abstract] Three cleaning methods, namely i) a commercial biocide applied by brush with the subsequent extraction of organic remains by a rod, ii) a scalpel or iii) a Nd:YVO4 laser at 355 nm, single application as well as ...
Femtosecond pulsed laser ablation for paint removal at oblique illumination: effect of the incidence angle
[Abstract] This research studies how the angle of incidence affects the ablation process when a pulsed femtosecond laser with a wavelength of 1040 nm and a high repetition rate is applied to spray paints used for graffiti. ...
Influence of Femtosecond Laser Modification on Biomechanical and Biofunctional Behavior of Porous Titanium Substrates
[Abstract] Bone resorption and inadequate osseointegration are considered the main problems of titanium implants. In this investigation, the texture and surface roughness of porous titanium samples obtained by the space ...
Femtosecond Laser Texturing as a Tool to Increase the Hydrophobicity of Ornamental Stone: The Influence of Lithology and Texture
[Abstract] In the field of stone conservation, a very common direct intervention seeks to increase the water repellence of objects. By limiting the interaction between the solid and the water, the possibility of alteration ...
