Touch-free reactive flash sintering of dense strontium hexaferrite permanent magnet
(John Wiley and Sons, 2023)
This work presents an extension of the touch-free flash sintering technique. In the proposed technique, chemical reaction and sintering occur in a single step, without the use of electrodes, in the presence of electric ...

Limitations of model-fitting methods for kinetic analysis: Polystyrene thermal degradation
(Elsevier, 2013)
In this paper, some clarifications regarding the use of model-fitting methods of kinetic analysis are provided in response to the lack of plot linearity and dispersion in the activation energy values for the thermal ...

Direct mechanosynthesis of pure BiFeO3 perovskite nanoparticles: reaction mechanism
(Royal Society of Chemistry (Great Britain), 2013)
In this work, a mechanochemical procedure is proposed as a simple and fast method to synthesize the pure BiFeO3 perovskite phase as a nanostructured material without the need for purification treatments, while the ...

Constant rate thermal analysis for thermal stability studies of polymers
(Elsevier, 2011)
This paper explores the relationship between the shapes of temperature-time curves obtained from experimental data recorded by means of constant rate thermal analysis (CRTA) and the kinetic model followed by the thermal ...

Constant rate thermal analysis of a dehydrogenation reaction
(Royal Society of Chemistry, 2016)
The Constant Rate Thermal Analysis (CRTA) procedure has been employed for the first time to study the kinetics of MgH2 dehydrogenation by thermogravimetry under high vacuum. CRTA implies controlling the temperature in such ...

Role of precalcination and regeneration conditions on postcombustion CO2 capture in the Ca-looping technology
(Elsevier, 2014)
The Ca-looping (CaL) technology is already recognized as a potentially viable method to capture CO2 from postcombustion gas in coal fired power plants. In this process, CO2 is chemisorbed by CaO solid particles derived ...

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 ...

Paving the Way to Establish Protocols: Modeling and Predicting Mechanochemical Reactions
(American Chemical Society, 2021)
Parametrization of mechanochemical reactions, or relating the evolution of the reaction progress to the supplied input power, is required both to establish protocols and to gain insight into mechanochemical reactions. Thus, ...

Synthesis of a nanosilica supported CO2 sorbent in a fluidized bed reactor
(Elsevier, 2015)
CaO has been deposited on a nanosilica powder matrix by a procedure based on atomic layer deposition (ALD) in a fluidized bed reactor at atmospheric pressure following a potentially scalable process. In previous works ALD ...
