      Effects of impurities on the ice microstructure of Monte Perdido Glacier, Central Pyrenees, NE Spain 

      González-Santacruz, N.; Muñoz-Marzagon, P.; Moreno, A.; Huidobro, J.; Faria, S.H. (Annals of Glaciology, 2023)
      Monte Perdido Glacier, located in the central Pyrenees, is one of the southernmost glaciers in Europe. Due to climate change, this glacier is suffering an accelerated mass loss, especially in the last decades. If the current ...

      Field validation of gap-type overhead conductor creep 

      Fernández Herrero, Elvira ORCID; Albizu Flórez, Igor ORCID; Bedialauneta Landaribar, Miren Terese ORCID; Mazón Sainz-Maza, Ángel Javier; Etxegarai Madina, Agurtzane (Elsevier, 2018-09-11)
      Gap-type overhead conductor sag-tension calculations based on experimental conductor creep tests are based on stress-strain and metallurgical creep tests. Although for bi-metallic conductors, these tests are carried out ...

      Kinetic Resolution of Secondary Allyl Boronates and Their Application in the Synthesis of Homoallylic Amines 

      Villar Arango, Laura; Orlov, Nikolai V.; Kondratyev, Nikolay S.; Uria Pujana, Uxue; Vicario Hernando, José Luis ORCID; Malkov, Andrei V. (Wiley-VCH, 2018-09-02)
      Highly enantioenriched, chromatographically-stable secondary allyl boronates featuring a 1,1,2,2-tetraethyl-1,2-ethanediol fragment (Epin) were obtained by kinetic resolution of their racemic mixtures. The Epin group at ...

      Carboxylates as Nucleophiles in the Enantioselective Ring-Opening of Formylcyclopropanes under IminiumIon Catalysis 

      Díaz, Estibaliz; Reyes Martín, Efraim; Uria Pujana, Uxue; Carrillo Fernández, María Luisa ORCID; Tejero, Tomás; Merino, Pedro; Vicario Hernando, José Luis ORCID (Wiley-VCH, 2018-04-12)
      In this work, carboxylic acids, which are typically regarded as poor nucleophiles, are demonstrated to be competent reagents to promote the ring-opening of formylcyclopropanes after activation of the latter through iminium ...
