Characterization of Talcose Rocks Derived from Serpentinite—Pilot Study in the Ultramafic Complex of Cabo Ortegal (Spain) for Potential Use and Commercialization
Pereira, Lola; Rivas Brea, Teresa; López, Ana; Ramil, Alberto; Bloise, Andrea (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 ... -
Development of processing strategies for 3D controlled laser ablation: Application to the cleaning of stonework surfaces
López, Ana; Lamas, Javier; Pozo Antonio, José Santiago; Rivas Brea, Teresa; Ramil, Alberto (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
Pozo Antonio, José Santiago; Rivas Brea, Teresa; López de Silanes, María Eugenia; Ramil, Alberto; López, Ana (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 ... -

Araújo Fernández, María; Rivas Brea, Teresa; Piñeiro Di Blasi, Jessica I.; Iglesias Comesaña, Carla; Saavedra González, Ángeles (Universidade da Coruña, 2014)[RESUMEN] El ámbito laboral de la minería está tradicionalmente ligado al género masculino, justificándose esta realidad, durante siglos, por la dureza de las condiciones de trabajo y la peligrosidad inherente a las labores ... -
Femtosecond Laser Texturing as a Tool to Increase the Hydrophobicity of Ornamental Stone: The Influence of Lithology and Texture
López, Ana; Pozo Antonio, José Santiago; Moreno, Alicia; Rivas Brea, Teresa; Pereira, Lola; Ramil, Alberto (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 ... -
Influence of the commercial finishes of ornamental granites on roughness, colour and reflectance
López, Ana; Pozo-Antonio, José Santiago; Ramil, Alberto; Rivas Brea, Teresa (Elsevier, 2018-09)[Abstract] The effects of the four common commercial finishes (polished, honed, disc cutting and bush hammering) on several properties of ornamental granites were evaluated. Two granites of different texture, widely used ... -
