4-Mercaptophenyldiphenylphosphine as linker to immobilize Pd onto the surface of magnetite nanoparticles. Excellent catalytic efficiency of the system after partial linker removal
(2015-10-27)
Article
Open AccessThis journal is © The Royal Society of Chemistry. The molecule 4-mercaptophenyldiphenylphosphine (Sdp) has been synthesized for use as a linker to immobilize Pd nanoparticles onto the surface of magnetite nanoparticles. ... -
Banco experimental de ondas torsionales generadas bajo el principio de magnetostricción para la detección de defectos en estructuras cilíndricas
(Universitat Politècnica de Catalunya, 2018-06-26)
Bachelor thesis
Open AccessDebido a las altas cargas que soportan las estructuras es probable que con el tiempo aparezcan grietas y, si no se controlan minuciosamente, se pueda llegar al colapso de la estructura. El colapso sin ... -
Influència dels materials magnètics en diverses màquines elèctriques rotatives
(Universitat Politècnica de Catalunya, 2005-11)
Master thesis (pre-Bologna period)
Restricted access - author's decisionEl fenomen del magnetisme ha anat agafant protagonisme en el camp de les màquines elèctriques, ja que els materials magnètics aporten bones qualitats al seu funcionament. L’objectiu d’aquest treball és analitzar el ... -
Magnetite-supported palladium single-atoms do not catalyse the hydrogenation of alkenes but small clusters do
(2016-01-01)
Article
Open AccessThe activity of supported noble metal catalysts strongly depends on the particle size. The ultimate small-size limit is the single-atom catalyst (SAC), which maximizes the catalytic efficiency in the majority of the examples. ... -
Martensitic transformation, thermal analysis and magnetocaloric properties of Ni-Mn-Sn-Pd alloys
(2020-12-01)
Article
Open AccessMartensitic transition and magnetic response of Ni50-x Pdx,y Mn36 Sn14-y (x = 0, 1, 2 and y = 0, 1) Heusler alloys were analysed. The crystalline structure of each composition was solved by X-ray diffraction pattern fitting. ... -
Modelling magnetostructural textures in magnetic shape-memory alloys: Strain and magnetic glass behaviour
(2014-10-01)
Article
Restricted access - publisher's policyIn this paper, we propose a model that combines a Landau free energy part and a micromagnetic free energy part aimed at describing a magnetostructural multiferroic. We show that in the limit of high-elastic anisotropy and ... -
Refredament magnètic: ordre i desordre d'imants atòmics
(2011)
Article
Open AccessS’ha comprovat que la refrigeració magnètica que utilitza un sistema magnètic és energèticament eficient i competitiva amb la tecnologia refrigerant basada en la compressió de gasos en el rang de temperatures proper a ... -
Spatially correlated disorder in self-organized precursor magnetic nanostructures
(2007-08-20)
Article
Restricted access - publisher's policyWe study the scaling behavior of the characteristic length of precursor magnetic nanostructures above the Curie temperature with the correlation length of quenched-in disorder. We found that the modulation length of the ... -
The JOREK non-linear extended MHD code and applications to large-scale instabilities and their control in magnetically confined fusion plasmas
(2021-06-01)
Article
Open AccessJOREK is a massively parallel fully implicit non-linear extended magneto-hydrodynamic (MHD) code for realistic tokamak X-point plasmas. It has become a widely used versatile simulation code for studying large-scale plasma ...
