Relative sea-level changes in the Basque coast (northern Spain, Bay of Biscay) during the Holocene and Anthropocene: The Urdaibai estuary case
(Elsevier, 2015)
In order to reconstruct the environmental evolution process of the Urdaibai estuary in response to sea-level changes in the Basque coast (northern Spain, Bay of Biscay) during the last 8500 years, 10 boreholes were drilled ...
Isolation of the effect of the hairy layer length on the mechanical properties of waterborne coatings
(Elsevier, 2015-07-19)
The effect of the acidic hairy layer length on the interdiffusion of polymer between particles and as a consequence on the mechanical properties of the films produced from waterborne coatings has been studied. In order to ...
Matrix Effect Compensation in Small-Molecule Profiling for an LC–TOF Platform Using Multicomponent Postcolumn Infusion
(ACS, 2015-05-12)
The possible presence of matrix effect is one of the main concerns in liquid chromatography–mass spectrometry (LC–MS)-driven bioanalysis due to its impact on the reliability of the obtained quantitative results. Here we ...
Quantitative determination of fentanyl in newborn pig plasma and cerebrospinal fluid samples by HPLC-MS/MS
(Wiley, 2015-03-09)
In this study, a selective and sensitive high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method requiring low sample volume (≤100 μL) was developed and validated for the quantitative determination ...
Males and females in EFL task-based interaction: does gender have an impact on LREs?
(Servicio de Publicaciones de la Universidad de Vigo, 2015)
This study analyzes the impact of gender on the language learning opportunities
available to Spanish EFL learners during task-based interaction. These learners worked
in mixed and matched gender dyads on four collaborative ...
Lignin oxidation and depolymerisation in ionic liquids
(RSC, 2015-09)
The depolymerisation of lignin directly in the black liquor was studied, comparing two ionic liquids as extracting solvents (butylimidazolium hydrogen sulphate and triethylammonium hydrogen sulphate), under oxidising ...
Kraft lignin as filler in PLA to improve ductility and thermal properties
(Elsevier, 2015-10)
[EN] Kraft lignin (KL) and acetylated Kraft lignin (AKL) were used as filler for the elaboration of composites
with poly(lactic acid) (PLA) in different concentrations (0.5, 1, 5, 10 and 20%) by extrusion method at
200 ...
Joint cost of energy under an optimal economic policy of hybrid power systems subject to uncertainty
(Elsevier, 2015-08-01)
Economical optimization of hybrid systems is usually performed by means of LCoE (levelized cost of energy) calculation. Previous works deal with the LCoE calculation of the whole hybrid system disregarding an important ...
In Vitro Degradation of PLCL/nHA Biodegradable Scaffolds
(Taylor & Francis, 2015-04-01)
We investigated the effect of bioactive nanoparticles on the in-vitro degradation of PLCL and
PLCL/nHA composite scaffolds. The concentration of nanohydroxyapatite significantly
affected the degradation rate. An increase ...
Hybrid materials based on azopolymer and sol-gel synthesized silver-containing titanium oxide nanoparticles with photoinduced birefringence
(The Royal Society of Chemistry, 2015-01-28)
The main goal of this work was the development of novel nanocomposite films with different optical
properties. A non-toxic water soluble azopolymer was modified with TiO2 nanoparticles and silver containing TiO2 nanoparticles. ...
