Influence of liquid media and laser energy on the production of MgO nanoparticl...
Pereira, H.; Moura, C. G.; Miranda, G.; Silva, Filipe SamuelNano and micro-sized metal particles are interesting solutions for several applications, from electronics to biomedical fields. In recent years, MgO has been gaining attention due to its nontoxicity and antibacterial activity, making this an interesting material for implants coating for instance. This study aims the fabrication/preparation of nanoparticles by laser ablation in liquid from the Mg bulk.The influe...
Laser induced synthesis of nickel alloy (alumel) nanoparticles in liquids
Moura, C. G.; Cano-Raya,C.; Grilo, J. P. F.; Viana, J. C.; Denchev, Z.; Nascimento, R. M.; Silva, F. S.Pulsed laser ablation in liquids (PLAL) has been growing as a powerful technique for the synthesis of multielement nanoparticles (NPs) such as metal alloys with complex composition. In consequence, there is a great necessity in expanding the current knowledge about alloy NPs formation during this method, aiming to control the chemical composition of produced NPs. In this work, a nanosecond Nd:YAG laser was used...
Laser surface texturing of Ti-6Al-4V by nanosecond laser: Surface characterizat...
Moura, C. G.; Carvalho, O.; Gonçalves, L. M. V.; Cerqueira, M. F.; Nascimento, R.; Silva, F.The development of smart biomedical implants with intrinsic communication system between sensors and actuators, or between implant and patient, remains a challenge for scientific community. Titanium and its alloys, especially Ti6Al4V, are the most used materials in the implant's fabrication. The present work is concerned with implant internal communication printing process and presents a detailed study on titan...
