The Value of Transfer of Knowledge in Bridging the Gender Gap in STEM
(MDPI, 2021-05)
[Abstract] Spanish researchers’ recent evaluations regarding the transfer of knowledge have shown that activities that could help close the gender gap in STEM areas are penalized upon evaluation. The results were very ...
Laser Surface Modification in Ti-xNb-yMo Alloys Prepared by Powder Metallurgy
(MDPI, 2021-02)
[Abstract] The main objective was to study the effect of surface modification by laser on Ti-Nb-Mo powder metallurgical alloys to improve their mechano-chemical behavior and their application as a biomedical implant. The ...
Surface Modification of Porous Titanium Discs Using Femtosecond Laser Structuring
(MDPI, 2020-06)
[Abstract] The failure of titanium implants is associated with two main problems that include the bone resorption and fracture of the surrounding bone tissue (stiffness incompatibility) and implant loosening (poor ...
Influence of Femtosecond Laser Modification on Biomechanical and Biofunctional Behavior of Porous Titanium Substrates
(MDPI, 2022-04-19)
[Abstract] Bone resorption and inadequate osseointegration are considered the main problems of titanium implants. In this investigation, the texture and surface roughness of porous titanium samples obtained by the space ...
Effect of Alloying Elements on Laser Surface Modification of Powder Metallurgy to Improve Surface Mechanical Properties of Beta Titanium Alloys for Biomedical Application
(Elsevier, 2021-09)
[Abstract] Beta-type titanium alloy surfaces (Tie35Nbe10Ta (TNT) and Tie30Nbe4Sn (TNS)) weremodified by laser using a power of 1000 W and speed of 6.7 mm/s (Condition A) and a powerof 1500 W with speed of 10 mm/s (Condition ...
Tribo-Mechanical and Cellular Behavior of Superficially Modified Porous Titanium Samples Using Femtosecond Laser
(ScienceDirect, 2021-09)
[Abstract] In this work, the surface of porous titanium samples obtained by the space-holder technique was treated with a femtosecond laser to improve their osseointegration. Instrumented micro-indentation and scratch test ...
Visualización de procesos de microdilatación inducidos por Láser mediante el uso de interferometría holográfica digital
(Centro de Investigaciones en Láseres y Aplicaciones (CEILAP), 2023-03-25)
[Resumen]: En este artículo se muestra el uso de holografía interferométrica digital para el estudio de procesos de microdilatación. Mediante el uso de un esquema óptico y una cámara CCD se realizaron interferogramas sobre ...
Femtosecond pulsed laser ablation for paint removal at oblique illumination: effect of the incidence angle
(Elsevier, 2022-06-09)
[Abstract] This research studies how the angle of incidence affects the ablation process when a pulsed femtosecond laser with a wavelength of 1040 nm and a high repetition rate is applied to spray paints used for graffiti. ...
Building Granite Characterisation, Construction Phases, Mason’s Marks and Glyptography of Nossa Senhora de Guadalupe Church, Mouçós e Lamares, Galicia-North Portugal Euroregion
(Springer, 2023-03)
[Abstract]: 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 ...
Robot-assisted laser ablation for 3D surfaces. Application for paint removal with ultrashort pulse laser
(Elsevier, 2023-01)
[Abstract] In this work, a robot-assisted laser cleaning system is presented that allows the automatic processing of 3D objects with arbitrary geometry. The system is based on the integration of a femtosecond pulse laser ...
