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 ...
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 ...
