Decomposition and arrow-like aggregation of fuzzy preferences
We analyze the concept of a fuzzy preference on a set of alternatives, and how it can be decomposed in a triplet of new fuzzy binary relations that represent strict preference, weak preference and indifference. In this ... -
Democracy of quasi-greedy bases in p-Banach spaces with applications to the efficiency of the thresholding greedy algorithm in the hardy spaces Hp(Dd)
We use new methods, specific for non-locally convex quasi-Banach spaces, to investigate when the quasi-greedy bases of a -Banach space for 0 < p < p are democratic. The novel techniques we obtain permit to show in particular ... -
Design of novel photoactive modified titanium silicalites and their application for venlafaxine degradation under simulated solar irradiation
Titanium silicalites (TS) are well-known materials for their use in industrial oxidation reactions, and although they are used as photocatalysts, their activity is limited. Therefore, numerous synthetic strategies are ... -
Design of photocatalytic functional coatings based on the immobilization of metal oxide particles by the combination of electrospinning and layer-by-layer deposition techniques
This work reports the design and characterization of functional photocatalytic coatings based on the combination of two different deposition techniques. In a first step, a poly(acrylic acid) + β-Cyclodextrin (denoted as ... -
Designing multifunctional protective PVC electrospun fibers with tunable properties
In this work, the electrospinning technique is used for the fabrication of electrospun functional fibers with desired properties in order to show a superhydrophobic behavior. With the aim to obtain a coating with the best ... -
Development of an irradiation equipment to accelerate the degradation of rosé wine in antique green and flint bottles
Flint bottles make ros´e wines more attractive to the customers and, also, allow them to detect oxidation problems in the color of these wines. Nonetheless, transparent bottles do not protect wines from light. In this ... -
Development of an α′-hydroxy enone for the aminocatalytic asymmetric formal conjugate addition of aldehydes to acrylates, vinyl ketones and acrolein
(Royal Society of Chemistry, 2023) Artículo / ArtikuluaAminocatalytic asymmetric conjugate addition of aldehydes to Michael acceptors is a well established C-C bond forming methodology. However, various acrylic-type acceptors, including acrylic acid derivatives and acrolein, ... -
Development of ceramic-MOF filters from aluminum saline slags for capturing CO2
This study describes the procedures followed to synthesize ceramic-MOF filters using aluminum saline slag wastes. Briefly, the raw aluminum saline slags were washed at 80 ◦C to significantly reduce the saline content and ... -
Diffuse irradiance on tilted planes in urban environments: evaluation of models modified with sky and circumsolar view factors
Numerous studies have analyzed existing irradiance models for estimating sky diffuse irradiance on tilted planes. However, few have evaluated the suitability of these models for estimating irradiance in obstructed environments, ... -
Direct analysis of aluminum alloys by CSigma laser-induced breakdown spectroscopy
We report the application of CSigma laser-induced breakdown spectroscopy (Cσ-LIBS) to quantitative analysis of aluminum alloys without sample preparation. Cσ-LIBS simplifies strongly the conventional calibration procedure ... -
Direct evidence of a graded magnetic interface in bimagnetic core/shell nanoparticles using electron magnetic circular dichroism (EMCD)
Interfaces play a crucial role in composite magnetic materials and particularly in bimagnetic core/shell nanoparticles. However, resolving the microscopic magnetic structure of these nanoparticles is rather complex. Here, ... -
Dynamic testing in columns for soil heavy metal removal for a car park SUDS
The increase in urban runoff brought about by a rise in impermeable surfaces has triggered the alteration and pollution of many aquatic systems. The overall goal of this research was to design a ‘Sustainable Urban Drainage ... -
Dynamics of axially symmetric perturbed Hamiltonians in 1:1:1 resonance
We study the dynamics of a family of perturbed three-degree-of-freedom Hamiltonian systems which are in 1:1:1 resonance. The perturbation consists of axially symmetric cubic and quartic arbitrary polynomials. Our analysis ... -
La educación centrada en el encuentro como forma singular de innovación
Antes de hablar de innovación educativa, necesitamos determinar qué entendemos por perfeccionar tanto el acto educativo como el proceso de crecimiento de las personas involucradas en él. Inspirados por la forma ... -
Effect of Cu substitution on the magnetic and magnetic induction heating response of CdFe₂O₄ spinel ferrite
In this work, a comparative study of the effect of Cu on the structural, magnetic and magnetic induction heating response in CdFe2O4 spinel is presented. The ceramic nanoparticles (Cu1−xCdxFe2O4; 0 ≤ x ≤ 1) were synthesized ... -
Effect of high pressure on the reducibility and dispersion of the active phase of Fischer-Tropsch catalysts
The effect of high pressure on the reducibility and dispersion of oxides of Co and Fe supported on -Al2O3, SiO2, and TiO2 has been studied. The catalysts, having a nominal metal content of 10 wt.%, were prepared by incipient ... -
