      Cruz Quesada, Guillermo Upna Orcid; Rosales Reina, Beatriz; López Torres, Diego Upna Orcid; Reinoso, Santiago Upna Orcid; López Ramón, María Victoria; Arzamendi Manterola, María Cruz Upna Orcid; Elosúa Aguado, César Upna Orcid; Espinal Viguri, Maialen Upna Orcid; Garrido Segovia, Julián José Upna Orcid (Elsevier, 2024)   Artículo / Artikulua  OpenAccess
      This work provides insight into the correlation between the luminescent response of a water-vapour optical fibre sensor and the textural properties of its lanthanide-doped silica coating. To this end, a library of 16 silica ...
    • Hybrid xerogels: study of the sol-gel process and local structure by vibrational spectroscopy 

      Cruz Quesada, Guillermo Upna Orcid; Espinal Viguri, Maialen Upna Orcid; López Ramón, María Victoria; Garrido Segovia, Julián José Upna Orcid (MDPI, 2021)   Artículo / Artikulua  OpenAccess
      The properties of hybrid silica xerogels obtained by the sol-gel method are highly dependent on the precursor and the synthesis conditions. This study examines the influence of organic substituents of the precursor on the ...
    • Novel silica hybrid xerogels prepared by co-condensation of TEOS and ClPhTEOS: a chemical and morphological study 

      Cruz Quesada, Guillermo Upna Orcid; Espinal Viguri, Maialen Upna Orcid; López Ramón, María Victoria; Garrido Segovia, Julián José Upna Orcid (MDPI, 2022)   Artículo / Artikulua  OpenAccess
      The search for new materials with improved properties for advanced applications is, nowadays, one of the most relevant and booming fields for scientists due to the environmental and technological needs of our society. ...
    • Organocatalytic Michael addition of unactivated a-branched nitroalkanes to afford optically active tertiary nitrocompounds 

      Lorea Revilla, Beñat; García-Urricelqui, Ane; Odriozola Ibarguren, José Manuel Upna Orcid; Razkin Lizarraga, Jesús; Espinal Viguri, Maialen Upna Orcid; Oiarbide, Mikel; Mielgo, Antonia; García Castillo, Jesús María Upna Orcid; Palomo, Claudio (ACS, 2023)   Artículo / Artikulua  OpenAccess
      The direct, asymmetric conjugate addition of unactivated ¿-branched nitroalkanes is developed based on the combined use of chiral amine/ureidoaminal bifunctional catalysts and a tunable acrylate template to provide tertiary ...
