“…The surface topographies of the ashlars have been obtained with a MEL M2DW laser profilometer connected to a laptop through the Ethernet-BlueBox (López et al 2020;Rodríguez et al 2023). The sensor has been mounted on a wooden structure that allows it to move in a straight line parallel to the reference plane that rests on the surface to be measured (Fig.…”

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 corbels that make up this church have a mason’s mark in the centre of their faces. The building granites (Sanguinhedo and Vale das Gatas) have been identified and characterised petrographically and petrophysically. The mason’s marks have been as well identified; all the ashlars with visible mason’s marks have been mapped, and a glyptographic study has been carried out. In addition, the surface roughness of ashlars was measured. All these analyses have made it possible to locate the main historical quarry, to calculate the number of stonemasons who worked in the construction of the church, and to determine its construction phases. There are eight main types of mason’s marks on the nave façades. The quarrymen extracted the main building granite (Sanguinhedo granite) from the same quarry, or from nearby quarries. Although the most experienced stonemason has been identified, most stonemasons worked as a team during all construction phases of the church. Techniques such as petrography, ultrasonic P wave velocity, colourimetry, roughness and the determination of hydric properties will guarantee the quality and durability of the heritage stone for restorations. In addition, the glyptographic analysis revealed important historical and ethnographic findings that will be very useful for the appreciation of the monument. Therefore, the knowledge of built heritage, such as mason’s marks contribute to the conservation of historical quarries and traditions, as well as help understand the close cultural association societies have had with heritage stones. In this way, the scientific corpus of historical-cultural heritage can face for the development of tourism in Galicia-North Portugal Euroregion in a long-lasting sustainable way.

“…Nesta metodologia, são utilizadas várias técnicas como ablação a laser, sputtering, litografia dentre outras (CHANG, 2006;LÓPEZ et al, 2020;SHAAT, 2018). Há algumas desvantagens na aplicação de experimentos didáticos dentro da metodologia top down que impossibilitam a aplicação no ensino remoto e muitas vezes no presencial, como o alto custo dos equipamentos e o alto grau de conhecimento e treinamento para operar os mesmos.…”

“…Laser ablation has also simplified the micropatterning of a vast quantity of materials since it is a self-sufficient process that does not need of posterior chemical treatments neither masks to pattern the surfaces. Recent works have even proposed strategies to perform laser ablation of 3D surfaces in real time [4].…”

Microfluidic devices manufacturing combining stereolithography and pulsed laser ablation

3D printing has revolutionized the field of microfluidics manufacturing by simplifying the typical processes offering a considerable accuracy and user-friendly procedures. For its part, laser ablation proves to be a versatile technology to perform detailed surface micropatterning. A hybrid technique that combines both technologies is proposed, employing them in their most suitable range of dimensions. This technique allows to manufacture accurate microfluidics devices as the one proposed: a microchannel, obtained using a stereolithographic printer, coupled with an array of microlenses, obtained by pulsed laser ablation of a 3D printed master.
