Parametric study of the operational and economic feasibility of Stirling micro-cogeneration devices in Spain
(Elsevier, 2013-12-19)
This paper analyses the operational and economic viability of Stirling engine-run micro-cogeneration units in single-family houses in Spain. Thermal demands for the reference dwelling, sited in three different and ...
Analysis of Local Measurement-Based Algorithms for Fault Detection in a Multi-Terminal HVDC Grid
(MDPI, 2019-12-17)
One of the most important challenges of developing multi-terminal (MT) high voltage direct current (HVDC) grids is the system performance under fault conditions. It must be highlighted that the operating time of the ...
Provisioning ecosystem services supply and demand: the role of landscape management to reinforce supply and promote synergies with other ecosystem services
(Elsevier, 2015-03-14)
Currently, trade enables regions to have a higher provisioning ecosystem services (ES) demand than that provided by ecosystems in the same region. This practice leads to a supply and demand provisioning ES scale mismatch, ...
A comparative thermodynamic study on the CO2 conversion in the synthesis of methanol and of DME
(Elsevier, 2017-02-01)
A thermodynamic approach of the synthesis processes of methanol and DME from H2+CO+CO2 has been conducted, in order to compare the feasibility of incorporating CO2 in the feed of both processes. The effects of reaction ...
Semantically enhanced network analysis for influencer identification in online social networks
(Elsevier, 2017-09-20)
Influencers in a social network are members that have greater effect in the online social network (OSN) than the average member. In the specific social networks known as communities of practice, where the focus is an ...
Development and comparative analysis of the modeling of an innovative finned-plate latent heat thermal energy storage system
(Elsevier, 2013-09-01)
This paper presents an innovative finned-plate latent heat thermal energy storage system for its integration in cogeneration systems. For optimization purposes it is very important to maximize the efficiency of the ...
Sediment toxicity and bioaccumulation assessment in abandoned Copper and Mercury mining areas of the Nalón River basin (Spain)
(Springer, 2014-11-06)
Sediment toxicity and metal bioaccumulation were assessed at sites affected by historical copper (Cu)
and mercury (Hg) mining activities in the Nalón River basin, Asturias, Spain. Toxicity assessment of stream sediments ...
Growth of Co Nanomagnet Arrays with Enhanced Magnetic Anisotropy
(Wiley Blackwell, 2016-09)
A trigon structure formed by submonolayer gadolinium deposition onto Au(111) is revealed as a robust growth template for Co nanodot arrays. Scanning Tunneling Microscopy and X-Ray Magnetic Circular Dichroism measurements ...
Strain-induced effects in the electronic and spin properties of a monolayer of ferromagnetic GdAg 2
(Royal Society of Chemistry, 2016)
We report on the structural, electronic and magnetic properties of a monolayer of GdAg2, forming a moire pattern on Ag(111). Combining scanning tunneling microscopy and ab initio spin-polarized calculations, we show that ...
A General Modular Approach for the Solubility Tagging of BODIPY Dyes
(Elsevier, 2019-05-09)
We describe a general and practical strategy for the direct one-step incorporation of a tunable solubility module at the boron atom of F-BODIPY dyes. The tethering reaction uses easy-to-handle reagents, has broad functional ...
