Study of the Phase Transitions in the Binary System NPG-TRIS for Thermal Energy Storage Applications
(MDPI, 2020-03-05)
Neopentylglycol (NPG) and tris(hydroxymethyl)aminomethane (TRIS) are promising phase change materials (PCMs) for thermal energy storage (TES) applications. These molecules undergo reversible solid-solid phase transitions ...
Sensing Capacity in Dysprosium Metal & Organic Frameworks Based on 5-Aminoisophthalic Acid Ligand
(MDPI, 2022-04-28)
Two novel metal-organic frameworks (MOFs), based on dysprosium as the metal and the 5-aminoisophthalic acid (5aip) ligand, have been solvothermally synthesized, with the aim of studying and modulating their luminescence ...
High temperature internal friction in a Ti–46Al–1Mo–0.2Si intermetallic, comparison with creep behaviour
(Elsevier, 2016-01-15)
Advanced gamma-TiAl based intermetallics Mo-bearing have been developed to obtain the fine-grained microstructure required for superplastic deformation to be used during further processing. In the present work we have ...
Stress-assisted atomic diffusion in metastable austenite D03 phase of Cu-Al-Be shape memory alloys
(Pergamon-Elsevier, 2016-11)
Cu-Al-based shape memory alloys are firm candidates to be used up to 473 K. The main limiting aspect is the activation of diffusion processes in the metastable austenite phase, which drive the alloy decomposition. In the ...
Downscaling of surface moisture flux and precipitation in the Ebro Valley (Spain) using analogues and analogues followed by random forests and multiple linear regression
(Copernicus Gesellschaft, 2011)
In this paper, reanalysis fields from the ECMWF have been statistically downscaled to predict from large-scale atmospheric fields, surface moisture flux and daily precipitation at two observatories (Zaragoza and Tortosa, ...
Variability in the air-sea interaction patterns and timescales within the south-eastern Bay of Biscay, as observed by HF radar data
(Copernicus Gesellschaft MBH, 2013)
Two high-frequency (HF) radar stations were installed on the coast of the south-eastern Bay of Biscay in 2009, providing high spatial and temporal resolution and large spatial coverage of currents in the area for the first ...
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 ...
Universal Scaling Law for the Size Effect on Superelasticity at the Nanoscale Promotes the Use of Shape‐Memory Alloys in Stretchable Devices
(Wiley, 2020-02)
Shape-memory alloys (SMAs) are the most stretchable metallic materials thanks to their superelastic behavior associated with the stress-induced martensitic transformation. This property makes SMAs of potential interest for ...
Testing the Applicability of 119Sn Mössbauer Spectroscopy for the Internal Stress Study in Ternary and Co-Doped Ni-Mn-Sn Metamagnetic Alloys
(MDPI, 2021-03-09)
The influence of both the Co addition and the internal stress on the atomic level magnetism is comparatively studied in Ni50Mn37Sn13 and Ni45Mn38Sn13Co4 alloys by magnetic measurements and 119Sn Mössbauer spectroscopy. The ...
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 ...
