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 ...
Strengthening masonry vaults with organic and inorganic composites: An experimental approach
(Elsevier, 2015-11-15)
Polymer-reinforced fibers are now commonly applied to buildings for structural retrofitting purposes. These materials add greater tensile strength to structures, at the expense of a slight increase in weight. However, they ...
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. ...
Parasite transmission through suspension feeding
(ELSEVIER, 2015)
Suspension-feeding bivalve molluscs are confronted with a wide range of materials in the benthic marine environment. These materials include various sized plankton and the organic material derived from it, macroalgae, ...
In-plane shear behaviour of multiscale hybrid composites based on multiwall carbon nanotubes and long carbon fibres
(Sage, 2015-09-18)
Both in-plane shear modulus and in-plane shear strength of multiscale hybrid composites have been studied. Carbon fibre-based laminates have been fabricated including functionalized multiwall carbon nanotubes by means of ...
Evaluation of SWAT models performance to simulate streamflow spatial origin. The case of a small forested watershed
(Elsevier, 2015-06-01)
The Soil and Water Assessment Tool (SWAT) model has been applied widely in many types of environment with different goals. The purpose of this paper is to assess the ability of SWAT to simulate hydrological processes in ...
Estilo de vida y percepción de los cuidados en pacientes crónicos: hipertensos y diabéticos
(Fundación Index, 2015-12)
Conocer el estilo de vida de pacientes crónicos hipertensos y diabéticos, determinar los fenómenos que influyen en su autocuidado y analizar su percepción del cuidado profesional. Metodología: Estudio cualitativo de tipo ...
