Fractionation and fluxes of metals and radionuclides during the recycling process of phosphogypsum wastes applied to mineral CO2 sequestration
(Elsevier, 2015)
The industry of phosphoric acid produces a calcium-rich by-product known as phosphogypsum, which is usually stored in large stacks of millions of tons. Up to now, no commercial application has been widely implemented for ...

Characterization of the magnetic interactions of multiphase magnetocaloric materials using first-order reversal curve analysis
(AIP Publishing, 2015-04-28)
In order to understand the magnetocaloric response of materials, it is important to analyze the interactions between the different phases present in them. Recent models have analyzed the influence of these interactions on ...

Effect of α-Fe impurities on the field dependence of magnetocaloric response in LaFe11.5Si1.5
(Elsevier, 2015)
In this work, the theoretical field dependence of the magnetic entropy change far away from the transition is used to analyze the field dependence of composite materials formed by fcc La(Fe,Si)13 and bcc α-Fe(Si) phases. ...

On the use of classical JMAK crystallization kinetic theory to describe simultaneous processes leading to the formation of different phases in metals
(2015)
The classical theory of Johnson-Mehl-Avrami-Kolmogorov (JMAK) is widely used to describe the kinetics of crystallization even when the premises required for its application are not strictly fulfilled. In this paper we ...

Core regulatory network motif underlies the ocellar complex patterning in Drosophila melanogaster
(Elsevier, 2015)
During organogenesis, developmental programs governed by Gene Regulatory Networks (GRN) define the functionality, size and shape of the different constituents of living organisms. Robustness, thus, is an essential ...

Influence of Hot Compaction on Microstructure and Magnetic Properties of Mechanically Alloyed Fe(Co)-based Amorphous Compositions
(Elsevier, 2015)
Amorphous Fe75Nb10B15 and (Fe70Co30)75Nb10B15 alloys were prepared by mechanical alloying from the elemental constituents and hot compacted at different temperatures within the supercooled liquid region. After compaction, ...

Analysis of magnetocaloric effect of ball milled amorphous alloys: Demagnetizing factor and Curie temperature distribution
(Elsevier, 2015)
The magnetocaloric effect (MCE) has been measured for an amorphous mechanically alloyed (MA) Co62Nb6Zr2B30. It is demonstrated that sample shape must be taken into account for a correct interpretation of the results, ...

Ultra-fast and energy-efficient sintering of ceramics by electric current concentration
(Nature Publishing Group, 2015)
Electric current activated/assisted sintering (ECAS) techniques, such as electrical discharge sintering (EDS) or resistive sintering (RS), have been intensively investigated for longer than 50 years. In this work, a novel ...

Enhanced cryogenic magnetocaloric effect in Eu8Ga16Ge30 clathrate nanocrystals
(AIP Publishing, 2015)
We observe an enhanced magnetic entropy change ( D S M ) at cryogenic temperatures (T < 20 K) in Eu 8 Ga 16 Ge 30 clathrate (type-I) nanocrystals prepared by a ball milling method. With reduction in the ...
