Considerations on the programmed functional life (one generation) of a green artificial reef in terms of the sustainability of the modified ecosystem
Carral Couce, Luis; Tarrío-Saavedra, Javier; Cartelle Barros, Juan José; Camba, C.; Ramil, Alberto; Álvarez-Feal, José-Carlos (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
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 ... -
Enhancement of graffiti removal from heritage stone by combining laser ablation and application of a solvent mixture
Ricci, Chiara; Gambino, Francesca; Nervo, Marco; Piccirillo, Anna; Scarcella, Arianna; Zenucchini, Francesca; Ramil, Alberto; Pozo Antonio, José Santiago (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 ... -
