Hydrogenolysis of 5-hydroxymethylfurfural to produce 2,5-dimethylfuran over ZrO2 supported Cu and RuCu catalysts
(ACS, 2018-07-13)
Glucose dehydration to HMF and its hydrogenolysis to DMF, a suitable biofuel, have been studied using
the same catalysts for both processes. The 10CuZr catalyst shows the highest HMF yield (25.6%) with an acceptable glucose ...
Una aproximación didáctica para la conservación del patrimonio artístico de la Universidad del País Vasco UPV/EHU
(Grupo Español del Instituto Internacional de Conservación-GEIIC y ACRE- Asociación de Conservadores/as y Restauradores/as de España, 2018)
La colección de patrimonio artístico de la (UPV/EHU), se compone de diferentes obras de artistas contemporáneos que conviven en el entorno universitario. La recuperación de estas obras desde un enfoque didáctico pone en ...
How is communication of vaccines in traditional media: a systematic review
(SAGE on behalf of the Royal Society for Public Health, 2018-06-07)
Aim: Taking into account that a key determinant in public approval of vaccinations is how the
media constructs and frames messages about vaccination programmes, our aim is to review
communication studies exploring media ...
Highly packed graphene–CNT films as electrodes for aqueous supercapacitors with high volumetric performance
(Royal Society of Chemistry, 2018-01-24)
The increasing complexity of portable electronics demands the development of energy storage devices with higher volumetric energy and power densities. In this work we report a simple strategy for the preparation of partially ...
In-situ analytical study of bricks exposed to marine environment using hand-held X-ray fluorescence spectrometry and related laboratory techniques
(Elsevier, 2018-05-03)
In this work, the degradation processes that take place in bricks exposed to marine environments have been studied. Taking into account the importance of this building material where the silicates present in the final ...
Interferometer with a driven trapped ion
(2018-10-18)
We propose an interferometric measurement of weak forces using a single ion subjected to designed time-dependent spin-dependent forces. Explicit expressions of the relation between the unknown force and the final populations ...
Coupled spin and electron-phonon interaction at the Tl/Si(111) surface from relativistic first-principles calculations
(American Physical Society, 2018-12-28)
We investigate the role played by the electron spin and the spin-orbit interaction in the exceptional electron-phonon coupling at the Tl/Si(111) surface. Our first-principles calculations demonstrate that the particular ...
Reduced graphene oxide decorated with SnO2 nanoparticles as negative electrode for lithium ion capacitors
(Elsevier, 2018-07-25)
The effort to increase the energy density of conventional electric double-layer capacitors (EDLCs) goes through the development of lithium-ion capacitors (LICs). Herein, we report a self-standing, binder-free composite as ...
Regeneration of NiAl2O4 spinel type catalysts used in the reforming of raw bio-oil
(Elsevier, 2018-12-01)
The regenerability of Ni catalysts in reforming reactions is a key factor for process viability. Accordingly, this study addresses the regeneration of two spinel NiAl2O4 type catalysts by reaction-regeneration cycles in ...
Regenerability of a Ni catalyst in the in-line catalytic steam reforming of biomass pyrolysis volatiles
(Elsevier, 2018-12)
A study has been carried out of the regenerability of a commercial Ni catalyst used in the steam reforming of volatiles from biomass pyrolysis, determining the evolution of the reaction indices in successive reaction-regeneration ...
