Abstract: The search for materials with improved mechanical properties and functionalities has boosted the development of nanofibers. Nanofibers are novel materials with very special properties, different from their bulk counterparts, due to the very reduced size and consequent microstructural differences. In this expert talk two novel laser-assisted technologies, specifically developed for the production of nanofibers, will be introduced. First one, the Laser Spinning involves melting and elongation of a precursor material with tailored composition using a high power laser and a supersonic gas jet and can quickly produce a big quantity of glass nanofibers. Second one, the COFIBLAS (Continuous fiberizing by laser melting), an innovative method that produces nanofibers with lengths that are, effectively, unlimited by the process. Both techniques will be explained as well as the applications of the so produced nanofibers in the biomedical field, textile field, composite manufacturing, CO2 sequestration, etc.

About the Presenter: Prof. Juan Pou (Ind.Eng., MSc., Ph.D.) holds a chair of Applied Physics at the University of Vigo (northwestern Spain). He started to work with lasers in 1985 when he was a student in Vigo and helped to develop from scratch the larger laser materials processing research group in Spain. He is now the leader of that group. Prof. Pou has broad experience in transferring research to industry. He was director of the Research Centre for Advanced Industrial Technologies and Processes and dean of the School of Engineering also in Vigo. He has hands-on experience in different laser-assisted processes such as LCVD, PLD, laser cladding, cutting, micro/nano fabrication, additive manufacturing, etc. At present he is involved in the development of innovative processes such as controlling corrosion by laser treatment or production of nanoparticles and nanofibers by laser assisted processes. He is co author +150 papers in scientific journals (peer reviewed) and has been awarded 30 patents.

MODERATOR: Prof. Kapil Gupta, Mechanical and Industrial Engg. Technology (DFC)
