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 ...
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 ...
Ultrafast Laser Surface Texturing: A Sustainable Tool to Modify Wettability Properties of Marble
(MDPI, 2019-07-28)
[Abstract] Conservation strategies to reduce the degradation of stone caused by the action of water are focusing on increasing the hydrophobicity of the surface by imitating existing solutions in nature (lotus leafs and ...
Influence of the weathering rate on the response of granite to nanosecond UV laser irradiation
(Elsevier, 2019-12-13)
[Abstract]: Laser ablation is an accepted cleaning technology for cultural heritage stonework. Optimized laser ablation may,however, have different side effects depending on the mineralogical composition of the stone. In ...
Laser versus scalpel cleaning of crustose lichens on granite
(Elsevier, 2018-02-28)
[Abstract]: This paper addresses the evaluation of the cleaning of crustose lichens developing on granite. The evaluation was performed considering the effectiveness of the cleanings and harmfulness exerted on the granite. ...
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 ...
A computer vision system for identification of granite-forming minerals based on RGB data and artificial neural networks
(Elsevier, 2017-12-19)
[Abstract]: Granitic stones are widely used in the field of Cultural Heritage in the north-western Iberian Peninsula. In some activities regarding conservation, such as the laser cleaning, it is of great interest the ...
