  • Therapeutic applications of rose hips from different rosa species 

    Mármol, Inés; Sánchez de Diego, Cristina; Jiménez Moreno, Nerea Upna; Ancín Azpilicueta, Carmen Upna; Rodríguez Yoldi, María (MDPI, 2017)   Artículo / Artikulua  OpenAccess
    Rosa species, rose hips, are widespread wild plants that have been traditionally used as medicinal compounds for the treatment of a wide variety of diseases. The therapeutic potential of these plants is based on its ...
  • Microwave-assisted pillaring of a montmorillonite with al-polycations in concentrated media 

    González, Beatriz; Pérez, Alba Helena; Trujillano, Raquel; Gil Bravo, Antonio Upna; Vicente, Miguel A. (MDPI, 2017)   Artículo / Artikulua  OpenAccess
    A montmorillonite has been intercalated with Al3+ polycations, using concentrated solutions and clay mineral dispersions. The reaction has been assisted by microwave radiation, yielding new intercalated solids and leading ...
  • Asymmetric propionate aldol reactions of a chiral lithium enolate accessible from direct enolization with n-butyllithium 

    Palomo, Claudio; Oiarbide, Mikel; Gómez Bengoa, Enrique; Mielgo, Antonia; González Rego, María Concepción Upna; García Castillo, Jesús María Upna; González Guerrero, Alberto Upna; Odriozola Ibarguren, José Manuel Upna; Bañuelos, Patricia Upna; Linden, Anthony (ARKAT USA, Inc., 2005)   Artículo / Artikulua  OpenAccess
    The presented lithium enolate-based methodology is suitable for access to propionate syn-aldol motifs with high levels of stereocontrol. The reactive lithium enolate species is generated by direct treatment of a camphor-based ...
  • Bioavailability of heavy metals in soils amended with sewage sludge 

    Morera Luzán, María Teresa Upna; Echeverría Morrás, Jesús Upna; Garrido Segovia, Julián José Upna (Agricultural Institute of Canada, 2002)   Artículo / Artikulua  OpenAccess
    The recycling of sewage sludge to agricultural land results in the slow accumulation of potentially toxic heavy metals in soils. A greenhouse experiment was conducted to determine the bioavailability of Cu, Ni, Pb and ...
  • 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, ...
  • Mobility of heavy metals in soils amended with sewage sludge 

    Morera Luzán, María Teresa Upna; Echeverría Morrás, Jesús Upna; Garrido Segovia, Julián José Upna (Agricultural Institute of Canada, 2001)   Artículo / Artikulua  OpenAccess
    Sewage sludges added to arable land can improve soil fertility and physical properties. However, the concentrations of heavy metals commonly found in sludges limits their application to soil. The purpose of this paper is ...
