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 ...
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 ...
Using Hyperspectral Imaging to Quantify Phototrophic Biofilms on Granite
(International Society for Environmental Information Sciences, 2020-03)
[Abstract]: This paper reports a non-invasive method for in situ biofilm quantification based on the use of hyperspectral imaging to analyze a chromatically and texturally heterogeneous substrate as granite colonized by ...
Enhancement of graffiti removal from heritage stone by combining laser ablation and application of a solvent mixture
(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 ...
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 ...
