Isotopic and in situ DRIFTS study of the CO2 methanation mechanism using Ni/CeO2 and Ni/Al2O3 catalysts
(Elsevier, 2019-12-23)
The CO2 methanation mechanism was studied for Ni/CeO2 and Ni/Al2O3 catalysts. The higher methanation activity and selectivity of Ni/CeO2 is attributed to: i) Ni/CeO2 combines two types of active sites efficient for CO2 ...
Non-destructive characterisation of the Elephant Moraine 83227 meteorite using confocal Raman, micro-energy-dispersive X-ray fluorescence and Raman-scanning electron microscope-energy-dispersive X-ray microscopies
(Springer, 2018)
The application of a non-destructive analytical procedure to characterise the mineral phases in meteorites is a key issue in order to preserve this type of scarce materials. In the present work, the Elephant Moraine 83227 ...
Miscibility, interactions and antimicrobial activity of poly(ε-caprolactone)/ chloramphenicol blends
(Elsevier, 2018-03-13)
Poly(ε-caprolactone) (PCL) has been blended with Chloramphenicol (CAM), a well-known bacteriostatic antibiotic, in order to obtain new biomaterials with antibacterial properties. The resulting samples have been thoroughly ...
Formation of a Nonlinear Optical Host–Guest Hybrid Material by Tight Confinement of LDS 722 into Aluminophosphate 1D Nanochannels
(Wiley, 2016-09-15)
In this work, hemicyanine dye LDS 722, is encapsulated into the 1-D elliptical nano-channels of MgAPO-11 aluminophosphate by crystallization inclusion method. The synthesis of the hybrid material has been optimized through ...
Miscibility and degradation of polymer blends based on biodegradable poly(butylene adipate-co-terephthalate)
(Elsevier, 2018-02-21)
The aim of this work is to analyse the effect of the preparation method on the miscibility of poly(butylene adipate-co-terephthalate) (PBAT) and poly(hydroxy ether of bisphenol A) (PH) blends and to provide a better ...
Moisture dependent thermal properties of hydrophilic mineral wool: application of the effective media theory
(2015-07-27)
Thermal properties of mineral wool based materials appear to be of particular importance for their practical applications because the majority of them is used in the form of thermal insulation boards. Every catalogue list ...
Role of Ce substitution in the magneto-crystalline anisotropy of tetragonal ZrFe10Si2
(Elsevier, 2018-10-25)
We report the study of Zr1-xCexFe10Si2 (x = 0.0, 0.3 and 0.6) compounds, with tetragonal ThMn12 structure, by means of neutron diffraction and Mössbauer spectroscopy to understand the role of Ce in the increasing ...
Nursing students’ alternative beliefs regarding care for patients suffering from depression
(Elsevier, 2018-02-03)
Depression is an illness that constitutes a major challenge for Public Health worldwide. Therefore, there is a clear need to receive training to care for this type of patient. This study sets out to identify non-scientific ...
Modification of Eucalyptus and Spruce organosolv lignins with fatty acids to use as filler in PLA
(2016-05-09)
Spruce (softwood) and Eucalyptus (hardwood) woods were used as raw material for lignin extraction by
organosolv process. Chemical, structural and thermal characterizations of the extracted lignin samples have
been performed ...
Late Quaternary marine ostracods of the Basque Basin (S Bay of Biscay) taxonomy and distribution
(Sociedad Española de Paleontología (SEP), 2018)
En este trabajo se describen la taxonomía y las distribuciones ecológicas y de edad de los ostrácodos del Cuaternario final en la Cuenca Vasca (S Golfo de Vizcaya). Más de cuarenta y cuatro mil especímenes han sido obtenidos ...
