Anisotropic lattice expansion determined during flash sintering of BiFeO3 by in-situ energy-dispersive X-ray diffraction
(Elsevier, 2019)
BiFeO3 has a Curie temperature (TC) of 825 °C, making it difficult to sinter using conventional methods while maintaining the purity of the material, as unavoidably secondary phases appear at temperatures above Tc. Flash ...

A new model of the carbonator reactor in the Calcium Looping technology for post-combustion CO2 capture
(Elsevier, 2015)
The Ca-Looping (CaL) process is considered as a promising technology for CO2 post-combustion capture in power generation plants yielding a minor penalty on plant performance as compared with other capture technologies ...

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 ...

Phase-pure BiFeO3 produced by reaction flash-sintering of Bi2O3 and Fe2O3
(Royal Society of Chemistry, 2018)
Mixed powders of Bi2O3 and Fe2O3 are shown to yield single-phase, dense nanostructured polycrystals of BiFeO3 in reaction flash sintering experiments, carried out by applying a field of 50 V cm 1 and with the current ...
