Study of the dehydroxylation-rehydroxylation of pyrophyllite
(American Ceramic Society, 2010)
Pyrophyllite is a raw material of significant interest due to its large number of applications. Most of these applications require a thermal transformation of pyrophyllite; this thermal transformation implies the release ...

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 ...

Perspectives on oblique angle deposition of thin films: From fundamentals to devices
(Elsevier, 2016)
The oblique angle configuration has emerged as an invaluable tool for the deposition of nanostructured thin films. This review develops an up to date description of its principles, including the atomistic mechanisms governing ...

Nanoclay nucleation effect in the thermal stabilization of a polymer nanocomposite: A kinetic mechanism change
(American Chemical Society, 2012)
The enhanced thermal stability of polymer-clay nanocomposites over the original polymers is one of their most interesting features, and it has been profusely studied within the last decades. Here, a thorough kinetic analysis ...

WGS and CO-PrOx reactions using gold promoted copper-ceria catalysts: “bulk CuO-CeO2 vs. CuO-CeO2/Al2O3 with low mixed oxide content”
(Elsevier, 2016)
A copper-ceria bulk catalyst has been compared to a series of catalysts designed according to the as called “supported approach”, corresponding to the dispersion of low content mixed copper-ceria oxide on alumina matrix. ...

Biodegradable Polyester Films from Renewable Aleuritic Acid: Surface Modifications Induced by Melt-polycondensation in Air.
(IOP Publishing, 2016)
Good water barrier properties and biocompatibility of long-chain biopolyesters like cutin and suberin have inspired the design of synthetic mimetic materials. Most of these biopolymers are made from esterified mid-chain ...

Polyester films obtained by noncatalyzed melt-condensation polymerization of aleuritic (9,10,16-Trihydroxyhexadecanoic) acid in air
(Wiley-VCH, 2015)
To mimic nontoxic and fully biodegradable biopolymers like the plant cutin, polyester films from a natural occurring fatty polyhydroxyacid like aleuritic (9,10,16-trihydroxyhexadecanoic) acid have been prepared by noncatalyzed ...

Unraveling Discharge and Surface Mechanisms in Plasma-Assisted Ammonia Reactions
(American Chemical Society, 2020)
Current studies on ammonia synthesis by means of atmospheric pressure plasmas respond to the urgent need of developing less environmentally aggressive processes than the conventional Haber-Bosch catalytic reaction. Herein, ...

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 ...

Pyrolysis kinetics of ethylene-propylene (EPM) and ethylene-propylene-diene (EPDM)
(Elsevier, 2013)
The thermal degradation kinetics of several ethylene-propylene copolymers (EPM) and ethylene-propylene-diene terpolymers (EPDM), with different chemical compositions, have been studied by means of the combined kinetic ...
