Effect of different hemicelluloses characteristics on film forming properties
(Elsevier, 2013)
Hemicelluloses are known to have good gas barrier properties makes them of interest to film applications.
Corn cob, cotton waste, olive, apple tree pruning, pepper and chilli wastes were used as hemicelluloses
sources ...
Determining Flinders' bar correction by heeling the ship
(Spanish Society of Maritime Research (SEECMAR), 2013)
The aim of this article is to provide the compass adjuster with an innovative method of determining thelength of Flinders’ bar while the ship’s latitude remains unaltered. In this way the definitive compass ad-justment may ...
Fermentable sugars recovery from grape stalks for bioethanol production
(Elsevier, 2013-07-02)
[EN]Three different processes were investigated for the recovery of fermentable sugars from grape stalks:
autohydrolysis at 121 ºC before and after a pre-washing step and acid hydrolysis (2% H2SO4 w/w) after a
pre-washing ...
Application of Cognitive Techniques to Adaptive Routing for VANETs in City Environments
(Springer, 2013-09-29)
The evolution of smart vehicles has widened the application opportunities for vehicular ad hoc networks.
In this context, the routing issue is still one of the main challenges regarding the performance of the network.Although ...
Generation of nanocomposites based on polystyrene grafted CdSe nanoparticles by grafting through and block copolymer
(Springer Nature, 2013-02-23)
Continuing with our previous work, in which CdSe nanoparticles were functionalized with polystyrene (PS) brushes (CdSe-PS) by grafting through method, nanocomposites were prepared by adding them to a poly (styrene-b-buta ...
High levels of molecular orientation of surface azo chromophores can be optically induced even in a wet biological environment
(2013-09-18)
We have developed polyelectrolyte multilayer bio-films containing azobenzene chromophores that enhance reversible photo-orientation
upon irradiation with linearly polarized light, to effect surface photoswitching of ...
Contribution of defects to the spin relaxation in copper nanowires
(Americal Physical Society, 2013-03-18)
The contributions to the spin relaxation in copper (Cu) nanowires are quantified by carefully analyzing measurements of both charge and spin transport in lateral spin valves as a function of temperature and thickness. The ...
In Vitro Degradation of PLLA/nHA Composite Scaffolds
(Wiley, 2013-11-08)
Porous Poly-L-lactide (PLLA) scaffolds and PLLA/nanohydroxyapatite
(nHA) composite scaffolds with interconnected
pore networks and a porosity of over 90% were
fabricated with lyophilization techniques. In this study, ...
Internal characterization and hole formation mechanism in the laser percussion drilling process
(Elsevier, 2013-09-09)
Laser percussion drilling is increasing its relevance in many industrial applications, being used particularly in the aircraft industry in performing the micro-holes in nickel based alloys turbine blades for cooling, or ...
Non-linear analytical model of composites based on basalt textile reinforced mortar under uniaxial tension
(Elsevier, 2013-12-01)
[EN] The recent development of inorganic based composites as low-cost materials in reinforced concrete structural strengthening and precast thin-walled components, requires the creation of models that predict the mechanical ...
