Microstructure and Phase Formation of Novel Al80Mg5Sn5Zn5X5 Light-Weight Complex Concentrated Aluminum Alloys
(MDPI, 2021-12-01)In this work, three novel complex concentrated aluminum alloys were developed. To investigate the unexplored region of the multicomponent phase diagrams, thermo-physical parameters and the CALPHAD method were used to ... -
Microtab design and implementation on a 5MW wind turbine
(MDPI, 2017-05-24)Microtabs (MT) consist of a small tab placed on the airfoil surface close to the trailing edge and perpendicular to the surface. A study to find the optimal position to improve airfoil aerodynamic performance is presented. ... -
Microtechnologies for Cell Microenvironment Control and Monitoring
(MDPI, 2017-06)A great breadth of questions remains in cellular biology. Some questions cannot be answered using traditional analytical techniques and so demand the development of new tools for research. In the near future, the development ... -
Los microvertebrados en el registro arqueo-paleontológico del País Vasco: cambios climáticos y evolución paleoambiental durante el Pleistoceno Superior
(2015-07-24)En la presente tesis doctoral hemos estudiado el registro microfaunístico de cuatro yacimientos del Pleistoceno Superior del País Vasco, a fin de reconstruir el paleoambiente y el paleoclima en el que vivieron diversas ... -
Microvinifications in wild grapevine relic populations of Spain and France
(Aranzadi, 2020-12)[ES] Se ha realizado la microvinificación de nueve poblaciones de vid silvestre euroasiáticas situadas en diferentes hábitats de La Rioja (España) y el País Vasco (España, Francia). Las poblaciones se observaron previamente ... -
Microwave absorption properties of permalloy nanodots in the vortex and quasi-uniform magnetization states
(IOP Publishing, 2014-06-19)When the in-plane bias magnetic field acting on a flat circular magnetic dot is smaller than the saturation field, there are two stable competing magnetization configurations of the dot: the vortex and the quasi-uniform ... -
Microwave Photodetection with Superconducting Circuits
(2020-01-16)[EN] Single-photon photodetection of propagating microwaves is a long-standing question in the area of superconducting circuits. Initially, it was merely a scientific question, since applications of propagating quantum ... -
Microwave Resonant and Zero-Field Absorption Study of Doped Magnetite Prepared by a Co-Precipitation Method
(MDPI, 2014-06)Fe3O4 and ZnxFe3-xO4 pure and doped magnetite magnetic nanoparticles (NPs) were prepared in aqueous solution (Series A) or in a water-ethyl alcohol mixture (Series B) by the co-precipitation method. Only one ferromagnetic ... -
Microwave synthesis and photophysical characterization of hybrid materials based on the encapsulation of dyes into unidirectional aluminophosphates
(2017-07-07)In this work, hemicyanine dyes LDS 722 and LDS 730 are encapsulated into the 1D nanochannels of MgAPO-11 and MgAPO-5 aluminophosphates via crystallisation inclusion method. The synthesis of the hybrid material has been ... -
Microwave-assisted esterification of bleached and unbleached cellulose nanofibers
