Large-scale high-temperature solar energy storage using natural minerals
(Elsevier, 2017)
The present work is focused on thermochemical energy storage (TCES) in Concentrated Solar Power (CSP) plants by means of the Calcium-Looping (CaL) process using cheap, abundant and non-toxic natural carbonate minerals. CaL ...

‘Reliability of new poly (Lactic-co-glycolic acid) membranes treated with oxygen plasma plus silicon dioxide layers for pre-prosthetic guided bone regeneration processes’
(Medicina Oral, 2017)
Background: The use of cold plasmas may improve the surface roughness of poly(lactic-co-glycolic) acid (PLGA) membranes, which may stimulate the adhesion of osteogenic mediators and cells, thus accelerating the biodegradation ...

Characterization of mechanosynthesized Bi1−xSmxFeO3 samples unencumbered by secondary phases or compositional inhomogeneity
(Elsevier, 2017)
High-quality samples, in terms of phase purity and dielectric properties, of composition Bi1−xSmxFeO3 (0.05 ≤ x ≤ 0.20) have for the first time been prepared by mechanosynthesis. Close inspection of the powder diffraction ...

Structuring Pt/CeO2/Al2O3 WGS catalyst: Introduction of buffer layer
(Elsevier, 2017)
This work is devoted to the development of novel structured catalytic system for WGS reaction. The new concept is related to the presence of a pre-catalytic “buffer” layer formed by WGS-inert oxide, i.e. not involved in ...

Synthesis and characterization of Rh/MnO2-CeO2/Al2O3 catalysts for CO-PrOx reaction
(Elsevier, 2017)
Rh/MnO2-CeO2/Al2O3 catalysts with different manganese-to-ceria ratios have been synthesized, characterized and tested in CO-PrOx reaction. The physicochemical properties of the solids were studied by XRD, Raman spectroscopy, ...

Monitoring the Reaction Mechanism in Model Biogas Reforming by In Situ Transient and Steady-State DRIFTS Measurements
(Wiley-VCH, 2017)
In this work, the reforming of model biogas was investigated on a Rh/MgAlO catalyst. In situ transient and steady-state diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) measurements were used to gain ...

Plasma assisted deposition of single and multistacked TiO2 hierarchical nanotubes photoanodes
(Royal Society of Chemistry, 2017)
We present herein an evolved methodology for the growth of nanocrystalline hierarchical nanotubes combining physical vapor deposition of organic nanowires (ONWs) and plasma enhanced chemical vacuum deposition of anatase ...

Formation of nitrile species on Ag nanostructures supported on a-Al2O3: a new corrosion route for silver exposed to the atmosphere
(Institute of Physics Publishing, 2017)
The aging of supported Ag nanostructures upon storage in ambient conditions (air and room temperature) for 20 months has been studied. The samples are produced on glass substrates by pulsed laser deposition (PLD); first a ...

Insolubilization and thermal stabilization of a long-chain polyester by noncatalyzed melt-polycondensation synthesis in air
(Wiley, 2017)
Self-standing films of poly(ω-hydroxyl hexadecanoic acid) [poly(ω-OHC16)] have been prepared by noncatalyzed melt-polycondensation in air at 150, 175, and 200 °C. Poly(ω-OHC16)s obtained are characterized as polyesters by ...

Large-Scale Storage of Concentrated Solar Power from Industrial Waste
(American Chemical Society, 2017)
Deep penetration of renewable energies into the grid relies on the development of large-scale energy storage technologies using cheap, abundant, and nontoxic materials. Concentrated solar power (CSP) is particularly suitable ...
