Reactive SPS for sol–gel alumina samples: Structure, sintering behavior, and mechanical properties
(Elsevier, 2021)
This work presents a fast and direct controlled routine for the fabrication of fully dense alumina based on the reactive spark plasma sintering (reactive-SPS) of boehmite (γ-AlOOH) nano-powders obtained by the sol–gel ...

First- and second-order phase transitions in RE6Co2Ga (RE = Ho, Dy or Gd) cryogenic magnetocaloric materials
(Science in China Press, 2021)
Rare-earth (RE) rich intermetallics crystallizing in orthorhombic Ho6Co2Ga-type crystal structure exhibit peculiar magnetic properties that are not widely reported for their magnetic ordering, order of magnetic phase ...

Analysis of the magnetic field dependence of the isothermal entropy change of inverse magnetocaloric materials
(Elsevier, 2021)
In this work, the magnetic field dependence of the inverse magnetocaloric (MC) effect is analyzed using a mean field approach for describing antiferromagnetic to ferromagnetic magnetoelastic transitions. The model is able ...

Increased magnetocaloric response of FeMnNiGeSi high-entropy alloys
(Elsevier, 2021)
The search for high-entropy alloys (HEAs), a new class of materials, with high magnetocaloric perfor- mance can address the open question about their potential in functional applications. HEAs exist in a vast compositional ...

The role of Ni in modifying the order of the phase transition of La(Fe,Ni,Si)(13)
(Elsevier, 2018)
In this work, we study the effect of Ni substitution on the magnetocaloric properties of La(Fe,Si)13 compounds. Sample quality has been optimized by a combination of induction melting and suction casting techniques, which ...

A concise rebuttal on a concise proof of the equivalence of the Nernst theorem and the heat capacity statement of the third law of thermodynamics
(World Scientific Publishing, 2024-06-01)
The interplay between adiabatic cooling and isothermal ordering is analyzed to rebut the proof of the equivalence of the Nernst theorem and the heat capacity statement of the third law presented by Su and Chen.

Evidence of latent heat in Rb2ZnCl4 commensurate-incommensurate phase transition
(IOP Publishing, 2000-03-27)
The commensurate-incommensurate phase of a Rb2ZnCl4 crystal was studied using a conduction calorimeter. By identifying the contribution of specific heat to transition enthalpy it was possible to show, for the first time ...

Capture of CO2 through phosphogypsum and lye residues from the olive industry
(2023-05-22)
A new carbonation procedure is presented to recycle waste from phosphoric acid production, known as phosphogypsum (PG). The PG is treated with lye (NaOH solution) used in the olive industry instead of commercial NaOH. ...
