Higher-Order Topological Insulators
(American Association for the Advancement of Science, 2018-06)
Three-dimensional topological (crystalline) insulators are materials with an insulating bulk but conducting surface states that are topologically protected by time-reversal (or spatial) symmetries. We extend the notion of ...
A Charge-Transfer Salt Based on Ferrocene/Ferrocenium Pairs and Keggin-Type Polyoxometalates
(MDPI, 2018-11-30)
A new hybrid inorganic-organometallic salt has been obtained from the reaction of the Keggin-type silicotungstate anion with ferrocene in a water/methanol mixture as a result of the partial oxidation of ferrocene molecules ...
Numerical and observational study of the water balance over the Iberian Peninsula
(2018-03-19)
Esta tesis estudia el balance de humedad sobre la Península Ibérica utilizando diferentes configuraciones del modelo WRF (sin y con asimilación de datos cada6 horas) y explora las posibilidades de los métodos de downscaling ...
Historical Evolution of theWave Resource and Energy Production off the Chilean Coast over the 20th Century
(MDPI, 2018-09)
The wave energy resource in the Chilean coast shows particularly profitable characteristics for wave energy production, with relatively high mean wave power and low inter-annual resource variability. This combination is ...
The Influence of Thermal History on the Multistage Transformation of NiTi Shape-Memory Alloys
(MDPI, 2018-04)
The multistage martensitic phase transformation of a polycrystalline NiTi shape-memory alloy (50.3 at. %Ni-49.7 at. % Ti) has been studied by means of calorimetric measurements. After a conventional thermal treatment ...
Low temperature texture development in Nd 2 Fe 14 B/ α -Fe nanocomposite magnets via equal channel angular pressing
(American Institute of Physiscs, 2018-05)
While suitable texture has been developed in Nd2Fe14B/alpha-Fe nanocomposites via thermomechanical processing methods such as die upsetting by incorporating low melting point eutectic Nd-Cu additives, significant grain ...
MIDAS: A Benchmarking Multi-Criteria Method for the Identification of Defective Anemometers in Wind Farms
(MDPI, 2018-12-22)
A novel multi-criteria methodology for the identification of defective anemometers is shown in this paper with a benchmarking approach: it is called MIDAS: multi-technique identification of defective anemometers. The ...
Electricity production, capacity factor, and plant efficiency index at the Mutriku wave farm (2014–2016)
(Elsevier, 2018-01-01)
Mutriku has recently become the first commercial wave farm to release its operating data. The plant has 14 OWC operating turbines, and this study has conducted an analysis of hourly data corresponding to the 2014–2016 ...
Thermal radiative properties of electron-beam-melted and mechanically alloyed V-4Cr-4Ti based alloys between 200 and 750 ºC
(Elsevier, 2018-11-02)
The directional spectral emissivities of two V-4Cr-4Ti family alloys, candidate structural materials for fusion first wall/blanket applications, were measured between 200 °C and their working temperatures (700–750 °C), ...
