Characterization of Talcose Rocks Derived from Serpentinite—Pilot Study in the Ultramafic Complex of Cabo Ortegal (Spain) for Potential Use and Commercialization
(MDPI, 2023-11-09)[Abstract] Cabo Ortegal, in Spain, was declared a UNESCO Global Geopark in 2023. An ultramafic complex makes it a geologically exciting unit, where many research works have been carried out. Serpentinites, formed by the ... -
Colour changes in Galician granitic stones induced by UV Nd:YAG laser irradiation
(CRC, 2008)[Resumen]: estudio sobre el cambio de color del granito gallego al limpiarlo mediante láser ultravioleta -
Compositional depth profiles of gilded wood polychromes by means of LIBS
(CRC, 2008)[Resumen] Se analizan las diferentes capas existentes en retablos de maderas policromadas del periodo barroco. Se distinguen la capa base y las posteriores hasta el acabado mas superficial. Se aprecian las diferentes ... -
Considerations on the programmed functional life (one generation) of a green artificial reef in terms of the sustainability of the modified ecosystem
(Elsevier. Cell Press, 2023-04)[Abstract] The installation of artificial reefs serves to enhance marine ecosystems, although it also modifies them. These changes do not have to be irreversible, since it is possible to treat the functional life of an ... -
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 ... -
Dual Combination of Cleaning Methods (Scalpel, Biocide, Laser) To Enhance Lichen Removal From Granite
(Elsevier, 2022-03)[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 ... -
Effect of Alloying Elements on Laser Surface Modification of Powder Metallurgy to Improve Surface Mechanical Properties of Beta Titanium Alloys for Biomedical Application

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 ... -
Evaluation of femtosecond laser texturing on carbonate heritage stones
(CRC Press, 2024)[Abstract]: The effect of femtosecond laser texturing on Carrara marble, Montesclaros marble, and Redueña dolostone was evaluated. Mineralogical characterisation, laser structuring of thin sections and hand samples of the ... -
Experimental and numerical analysis of three-dimensional semi-rigid steel joints under non-proportional loading
(Elsevier, 2012-05)[Abstract], This paper focuses on the study of a type of three-dimensional joint that consists of extended end-plates for both major and minor axes. The minor axis connections are bolted to a plate welded to the column ... -
Femtosecond Laser Removal of Antifouling Paints on Glass Fibre Reinforced Plastic Used in Maritime Industry
(Elsevier, 2025-01)[Abstract] In this work we investigated the use of ultrashort laser pulses to clean antifouling paint from samples of glass fibre reinforced polymer (GFRP), a composite material widely used in shipbuilding. Samples were ... -
Femtosecond Laser Texturing as a Tool to Increase the Hydrophobicity of Ornamental Stone: The Influence of Lithology and Texture
(Elsevier, 2022-07)[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 ... -
Femtosecond pulsed laser ablation for paint removal at oblique illumination: effect of the incidence angle
(Elsevier, 2022-06-09)[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. ... -
