    • Characterization of duplex coating system (HVOF + PVD) on light alloy substrates 

      Colominas Guàrdia, Carles; Picas Barrachina, Josep Anton; Menargues Muñoz, Sergi; Martín Fuentes, E. (Enric); Baile Puig, Maite (Surface and Coatings Technology. Vol.318 (2017), p.326-331, 2017-05)
      Light metals such as aluminium or magnesium alloys play an important role in many different industrial applications. However, aluminium and especially magnesium alloys show relatively poor resistance ...

    • Femtosecond Laser Texturization on Coated Steel 

      Baldi Boleda, Tomàs; Colominas Guàrdia, Carles; García Granada, Andrés-Amador (Coatings 2022, 12(10), 1602, 2022)
      Surface textures such as laser-induced periodic surface structures (LIPSS) are of great interest to obtain industrial nanopatterns. In this work, plain uncoated 1.2344 steel with and without Chromium ...

    • Heteroacoplamientos catalizados por paladio 

      Teixidó i Closa, Jordi; Sánchez García, David; Borrós i Gómez, Salvador; Nonell, Santi; Borrell Bilbao, José Ignacio; Colominas Guàrdia, Carles (Afinidad. Vol.59, n.500 (2002), p.325-336, 2002)
      Durante los diez últimos años la química del paladio se ha aplicado intensamente en síntesis orgánica debido a su versatilidad y a su gran selectividad. En esta breve revisión se muestran las características ...

    • Influence of the carbon incorporation on the mechanical properties of TiB2 thin films prepared by HiPIMS 

      Sala, N.; Abad, Manuel David; Sánchez-López, J.C.; Crugeira, F.; Ramos-Masana, A.; Colominas Guàrdia, Carles (International Journal of Refractory Metals and Hard Materials. Vol.107 (2022), 105884, 2022-09)
      Nanostructured TiB2 and TiBC thin films with carbon contents up to 11 at. % were prepared by physical vapor deposition using high power impulse magnetron sputtering (HiPIMS) technology. The influence ...

    • Nb–C thin films prepared by DC-MS and HiPIMS: Synthesis, structure, and tribomechanical properties 

      Sala, N.; Abad, Manuel David; Sánchez-López, J.C.; Caro, J.; Colominas Guàrdia, Carles (Surface and Coatings Technology. Vol.422 (2021), 127569, 2021-09-25)
      Nanostructured Nb-C thin films were prepared by direct current magnetron sputtering (DC-MS) and high-power impulse magnetron sputtering (HiPIMS). The films were characterized in depth by X-ray diffraction ...

    • Simulation Approach for Hydrophobicity Replication via Injection Molding 

      Baldi Boleda, Tomàs; Sadeghi, Ehsan; Colominas Guàrdia, Carles; García Granada, Andrés-Amador (Polymers, 2021-06-23)
      Nanopattern replication of complex structures by plastic injection is a challenge that requires simulations to define the right processing parameters. Previous work managed to simulate replication for ...

    • Síntesis y aplicación de homocompuestos de TiO2 a la eliminación de contaminantes 

      Colominas Guàrdia, Carles; Costa, Miquel (Afinidad. Vol.68, n.554 (2011), p.259-262, 2011-07)
