Impact of adding white pomace to red grapes on the phenolic composition and color stability of syrah wines from a warm climate
(American Chemical Society, 2014-03-26)
The influence of the fermentative addition of Pedro Ximenez grape pomace (PXGP, white variety) on the phenolic composition and color of Syrah red wines from a warm climate was studied. Changes on phenolic composition (HPLC), ...

Improvement of Vickers hardness measurement on SWNT/Al2O3 composites consolidated by spark plasma sintering
(Elsevier, 2014)
Dense alumina composites with different carbon nanotube content were prepared by colloidal processing and consolidated by Spark Plasma Sintering (SPS). Single-wall carbon nanotubes (SWNTs) were distributed at grain boundaries ...

Fabrication of Gelatin/Bioactive Glass Hybrid Scaffolds for Bone Tissue- Engineering
(Springer, 2014)
In this work, hybrid scaffold materials composed of gelatin and Bioactive Glass (BG) have been fabricated. BG particulates in the ternary system SiO2 − CaO − P 2 O 5 have been synthesized initially using the sol-gel method. ...

Nanocolumnar growth of thin films deposited at oblique angles: Beyond the tangent rule
(American Institute of Physics, 2014)
The growth of nanostructured physical vapor deposited thin films at oblique angles is becoming a hot topic for the development of a large variety of applications. Up to now, empirical relations, such as the so-called tangent ...

Structural Relaxation in Fe(Co)SiAlGaPCB Amorphous Alloys
(Elsevier, 2014)
The structural relaxation of multicomponent Fe(Co)SiAlGaPCB amorphous alloys was investigated calorimetrically for annealed samples over a wide temperature range below the glass transition temperature. Upon heating, the ...

Bright fireballs associated with the potentially hazardous asteroid 2007LQ19
(Oxford University Press, 2014)
We analyse here two very bright fireballs produced by the ablation in the atmosphere of two large meteoroids in 2009 and 2010. These slow-moving and deep-penetrating events were observed over Spain in the framework of our ...

Stability of solitary waves in the nonlinear Dirac equation with arbitrary nonlinearity
(American Physical Society, 2014)
We consider the nonlinear Dirac equation in 1 + 1 dimension with scalar-scalar self interaction g2κ+1(Ψ¯¯¯Ψ)κ+1 and with mass m. Using the exact analytic form for rest frame solitary waves of the form Ψ(x,t)=ψ(x)e−iωt for ...

Synthesis and luminescence of uniform europium-doped bismuth fluoride and bismuth oxyfluoride particles with different morphologies
(Royal Society of Chemistry (Great Britain), 2014)
Facile synthesis routes have been developed for the preparation of uniform cubic bismuth fluoride and bismuth oxyfluoride particles. The synthesis methods are based on homogeneous precipitation reactions at 120 °C in ...

Improved O2 evolution from a water splitting reaction over Er3+ and Y3+ co-doped tetragonal BiVO4
(Royal Society of Chemistry, 2014)
Erbium-yttrium co-doped BiVO4 with a tetragonal structure is synthesized by means of a surfactant free hydrothermal method. The studied photocatalyst shows good photoactivity under sun-like excitation for the degradation ...

Determination of Technological Maturity of Grapes and Total Phenolic Compounds of Grape Skins in Red and White Cultivars During Ripening by Near Infrared Hyperspectral Image: A Preliminary Approach
(Elsevier, 2014)
Hyperspectral images of intact grapes during ripening were recorded using a near infrared hyperspectral imaging system (900-1700 nm). Spectral data have been correlated with grape skin total phenolic concentration, sugar ...
