Abstract: The current hydrogen economy is in a phase marked by the low rate and efficiency of the hydrogenproduction from water and the energy generation by hydrogen oxidation into water. This first yearassessment explores the possibility of exploiting the change of electronical configuration due

Abstract The Interrelated aspects of thermo-mechanical behavior with a specific focus on microstructural characteristics and defects, such as partial and total dislocations densities and grain-boundaries (GBs) that span the nano to the micro, and how these characteristics affect failure modes,

Abstract: Abstract: The delicate alveolar structure of the mammalian lungs is stabilized against forces tending to its collapse, thanks to the coating of a complex lipid-protein network assembled by the pulmonary surfactant system. This material, assembled and secreted by type II pneumocytes,

Abstract: The equiatomic CoCrFeMnNi high entropy alloy (HEA) and its derivatives have attracted attention fromscientific community due to their mechanical properties, also at cryogenic conditions. Extensivemechanical twinning is mainly responsible for their outstanding mechanical response under

Abstract: The on-going energy crisis demands extensive research into new alternatives for enhancing the energy efficiency in electric motors. As a probable solution to this, soft magnetic materials (SMM) portray excellent properties with high saturation magnetisation (JS) and low coercivity

Abstract: Modern technology demands the development of strong and flame-resistant multifunctional thermoplastic-based nanocomposites that are also compatible with three-dimensional (3D) printing, as this method has become a standard production process in essential industries. This study tackles

Abstract Modeling the damage and fracture of materials has been a recurrent topic in solid mechanics and materials engineering in the last century. In the present there is a strong interest to extend these studies to model complex multiphysical problems including explicitly the effect of the

Abstract: The active materials used in current LIBs fall short in energetic terms due to their limited uptake of Li, so further development of these materials is needed. In contrast to the insertion materials usually used in the LIBs, alloy materials are not restricted by the sites in the host

Resumen: Nanocomposite materials based on a polymer matrix and nanomaterials (as Graphene Nanoplateletes, 2D clays or Metal Organic Frameworks) acting as additives are an exciting type of materials that bring the opportunity to create plastics with better properties (mechanical, thermal,

The PhD defence will take place in the “Salon de Grados”  of the Montegancedo Campus (Boadilla) where the Facultad de Informática is based (ETSI). The dissertation is entitled «Advanced deep Learning technologies for the smart manufacturing of structural composites». It was advised

Abstract Titanium alloys are widely employed in aerospace applications owing to superior properties such as a high specific strength and a good corrosion resistance. In particular, the variety of dual phase microstructures obtained through different thermo-mechanical processing routes enables

Abstract Functional and structural parts, made so far with metals, have been progressively reengineeredby replacing metallic materials by discontinuous fibre reinforced polymers and continuous fibrereinforced composites. Polymer composites are usually divided into two groups, advanced (orhigh

Abstract: Floating Catalyst Chemical Vapor Deposition (FCCVD) is a method for the synthesis of 1D nanoparticles, i.e., nanotubes and nanowires, in the aerosol phase. Specifically, 1-D nanoparticles grow on the surface of spherical catalyst nanoparticles while floating through a gas reactor. An

Abstract: Reconstructing the morphology of aerogels presents significant challenges if 3D visualizations of their mesoporous nanostructure are desired. Available microscopic and tomographic tools find it difficult to probe into all types of aerogels for the purposes of reconstructing their 3D

Abstract: We all are very familiar with graphene and carbon nanotubes and their extraordinary electronic and mechanical properties. Both materials are composed of sp2 carbon atoms; their structures look very similar locally but exhibit different properties due to the way their atoms are arranged

Abstract: Systems with broken continuous symmetry in ideal lattices cannot be rectified through rearrangement or deformation. Topological metamaterials featuring nontrivial, artificially induced phase transitions have emerged as pivotal constituents for engineering these topological defects,
