Investigation of Mg-Zn-Al metal alloys as new PCMs for latent heat energy storage applications
(2016-12-19)
The main objective of this thesis is to investigate metal alloys as phase change material (PCM) for thermal energy storage (TES) applications. In particular, This work consists to analyze and characterize a set of binary ...
Water Adsorption on the β-Dicalcium Silicate Surface from DFT Simulations
(MDPI, 2018-09-04)
beta-dicalcium silicate (beta-Ca2SiO4 or beta-C2S in cement chemistry notation) is one of the most important minerals in cement. An improvement of its hydration rate would be the key point for developing environmentally-friendly ...
Large magnetoelectric coupling in multiferroic oxide heterostructures assembled via epitaxial lift-off
(Nature, 2020-06-24)
Epitaxial films may be released from growth substrates and transferred to structurally and chemically incompatible substrates, but epitaxial films of transition metal perovskite oxides have not been transferred to electroactive ...
KIMERA: A Kinetic Montecarlo Code for Mineral Dissolution
(MDPI, 2020-09-18)
KIMERA is a scientific tool for the study of mineral dissolution. It implements a reversible Kinetic Monte Carlo (KMC) method to study the time evolution of a dissolving system, obtaining the dissolution rate and information ...
Anharmonic effects in thermoelectric and 2D materials
(2020-09-18)
Estudio teórico de los efectos anarmónicos en materiales termoeléctricos y bidimensionales. En el casode los materiales termoeléctricos SnSe y SnS, hemos visto que los efectos anarmónicos producentransiciones de fase de ...
Helmholtz Fermi surface harmonics: an efficient approach for treating anisotropic problems involving Fermi surface integrals
(IOP Publishing, 2014-06-09)
We present a new efficient numerical approach for representing anisotropic physical quantities and/or matrix elements defined on the Fermi surface (FS) of metallic materials. The method introduces a set of numerically ...
Spin-dependent and non-adiabatic phenomena related to the electron-phonon interaction in nanostructures with strong relativistic corrections.
(2020-04-03)
En esta tesis se estudian fenómenos no adiabáticos y dependientes del espín del electrón relacionados conla interacción electrón-fonón en nanoestructuras con fuertes correcciones relativistas. Se han realizadocálculos de ...
Infrared spectral emissivity studies on metals and materials for solar thermal power plants
(2016-09-12)
Dentro del marco industrial mundial y del País Vasco en particular el sector metalúrgico ha tenido y tiene un peso muy importante. En muchos de los materiales utilizados es vital conocer las pérdidas de calor por radiación, ...
Fragile Phases as Affine Monoids: Classification and Material Examples
(American Physical Society, 2020-07-01)
Topological phases in electronic structures contain a new type of topology, called fragile, which can arise, for example, when an elementary band representation (atomic limit band) splits into a particular set of bands. ...
Diagrama de difracción de familias de materiales con composición flexible: unificación estructural dentro del formalismo superespacial y desarrollo de un difractómetro de haz paralelo
(2007-06-01)
Recientemente, se ha comenzado a utilizar el formalismo superespacial para unificar las descripciones de los miembros de familias de estructuras de composición flexible, en un único modelo estructural. Estas estructuras ...
