Building Granite Characterisation, Construction Phases, Mason’s Marks and Glyptography of Nossa Senhora de Guadalupe Church, Mouçós e Lamares, Galicia-North Portugal Euroregion
(Springer, 2023-03)
[Abstract]: The Romanesque church of Nossa Senhora de Guadalupe of Mouçós e Lamares is located in Vila Real (North of Portugal). The exterior part of its nave is preserved almost unaltered. Most of the granite ashlars and ...
Robot-assisted laser ablation for 3D surfaces. Application for paint removal with ultrashort pulse laser
(Elsevier, 2023-01)
[Abstract] In this work, a robot-assisted laser cleaning system is presented that allows the automatic processing of 3D objects with arbitrary geometry. The system is based on the integration of a femtosecond pulse laser ...
The importance of prevention when working with hazardous materials in the case of serpentinite and asbestos when cleaning monuments for restoration
(MDPI, 2023-01)
[Abstract]: Abstract: Health risks are often overlooked when the consequences are not evident in the short term. In restoration work, some activities can generate particles that may affect the health of workers through ...
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. ...
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 ...
La investigación gallega en la aplicación de la tecnología láser para la limpieza de patrimonio cultural material: estrategias del pasado y del futuro
(Universidade da Coruña, Servizo de Publicacións, 2023-12-22)
[Abstract] The cleaning of cultural heritage elements is essential to ensure the durability and transmission of our cultural and artistic legacy. In Galicia, the importance of our stone-built heritage reflects the skill ...
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 ...
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 ...
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 ...
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 ...
