Applications of nanocolumnar films in medicine, energy and aerospace industry

Resumen del trabajo presentado en el 3rd Virtual Congress on Materials Science and Engineering - Materials Info 2021, celebrado de forma virtual del 27 de septiembre al 1 de octubre de 2021Nanocolumnar films can be manufactured by magnetron sputtering using the glancing angle deposition configuration. This technique is environmentally friendly, since it is carried out at RT in a single step and does not involve chemical products (therefore, without recycling problems). This methodology can be scaled up to large surfaces, representing a valid approach for the industrial production of nanostructured films [1]. I will show several applications of these systems in medicine, energy and aerospace industry. In particular: as antibacterial coatings for orthopedic implants [1,2]; as substrates for the identification of biomolecules in surface enhanced Raman spectroscopy, SERS [3]; as black metal coatings in the visible range [4]; as nanostructured electrodes for advanced perovskite solar cells [5]; as nanostructured surfaces with photo-induced self-cleaning activity [6]; and as anti-multipactor coatings for the space industr
