• Application of gold complexes in the development of sensors for volatile organic compounds 

      Luquin, Asunción Upna; Elosúa Aguado, César Upna; Vergara, Elena; Estella, Juncal Upna; Cerrada, Elena; Bariáin Aisa, Cándido Upna; Matías Maestro, Ignacio Upna; Garrido Segovia, Julián José Upna; Laguna, Mariano (World Gold Council, 2007)   Artículo / Artikulua  OpenAccess
      Two different kinds of sensors have been developed by using the same kind of vapochromic complexes. The vapochromic materials [Au2Ag2(C6F5)(4)L-2](n) have different colours depending on the ligand L. These materials change, ...
    • Cooperative detection applied to THz imaging cameras 

      Lizarraga Cubillos, Juan Camilo Upna; Betancourt Quiñones, Diego Upna; Río Bocio, Carlos del Upna (2009)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      THz technology for developing imaging systems has recently aroused great interest, mainly due to the large number of applications in which these frequencies can be used: security, vision in hard environments, etc. The ...
    • Fiber optic multiple-wavelength filter based on one dimensional photonic bandgap structures with defects 

      Del Villar, Ignacio Upna; Matías Maestro, Ignacio Upna; Arregui San Martín, Francisco Javier Upna (IEEE, 2004)   Artículo / Artikulua  OpenAccess
      In this paper, a theoretical analysis is given of an optical fiber multiple-wavelength tunable filter based on a onedimensional (1-D) photonic bandgap (PBG) structure with four defects. To understand the positioning of ...
