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 ...

Quantitative characterization of multicomponent polymers by sample-controlled thermal analysis
(American Chemical Society, 2010)
This paper explores the potential of sample-controlled thermal analysis (SCTA) in order to perform compositional analysis of multicomponent polymeric materials by means of thermogravimetric experiments. In SCTA experiments, ...

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 ...

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 ...

Kinetic analysis of complex solid-state reactions. A new deconvolution procedure
(American Chemical Society, 2011)
The kinetic analysis of complex solid-state reactions that involve simultaneous overlapping processes is challenging. A method that involves the deconvolution of the individual processes from the overall differential kinetic ...

Influence of ball milling on CaO crystal growth during limestone and dolomite calcination: Effect on CO2 capture at Calcium Looping conditions
(American Chemical Society, 2016)
The multicycle CO2 capture performance of CaO derived from the calcination of ball-milled limestone and dolomite have been tested under high temperature and high CO2 concentration environment for the first time. Here it ...

A new model for the kinetic analysis of thermal degradation of polymers driven by random scission
(Elsevier, 2010)
In this paper, a series of f(α) kinetic equations able to describe the random scission degradation of polymers is formulated in such a way that the reaction rate of the thermal degradation of polymers that go through a ...

The Oxy-CaL process: A novel CO2 capture system by integrating partial oxy2 combustion with the Calcium-Looping process
(Elsevier, 2017)
This paper proposes a novel CO2 capture technology from the integration of partial oxy18 combustion and the Calcium Looping capture process based on the multicycle 19 carbonation/calcination of limestone derived CaO. The ...

Generalized kinetic master plots for the thermal degradation of polymers following a random scission mechanism
(American Chemical Society, 2010)
In this paper, the f(α) conversion functions for random scission mechanisms have been proposed to allow for the construction of generalized master plots suitable for these kinds of mechanisms. The master plots have been ...
