Rotational dynamics in the plastic-crystal phase of ethanol: Relevance for understanding the dynamics during the structural glass transition
(American Physical Society, 2000)
The reorientational dynamics within the rotationally disordered cubic plastic phase of solid ethanol is investigated by means of the concurrent use of computer molecular dynamics and quasielastic neutron scattering. Motions ...

Magnetocaloric response of Fe75Nb10B15Fe75Nb10B15 powders partially amorphized by ball milling
(AIP Publishing, 2009)
The magnetocaloric response of mechanically alloyed Fe75Nb10B15 powders was studied for samples with different amorphous and nanocrystal volume fractions. Thermomagnetic properties scale following a 3 law for different ...

Calcium silicates synthesised from industrial residues with the ability for CO2 sequestration
(SAGE Publications Ltd, 2014)
This work explored several synthesis routes to obtain calcium silicates from different calcium-rich and silica-rich industrial residues. Larnite, wollastonite and calcium silicate chloride were successfully synthesised ...

Compressive strength degradation in ZrB2-based ultra-high temperature ceramic composites
(Elsevier, 2011)
The high temperature compressive strength behavior of zirconium diboride (ZrB2)-silicon carbide (SiC) particulate composites containing either carbon powder or SCS-9a silicon carbide fibers was evaluated in air. Constant ...

A procedure to extract the magnetocaloric parameters of the single phases from experimental data of a multiphase system.
(AIP Publishing, 2014)
In this work, we propose a method to extract the individual parameters that describe the field dependence of magnetic entropy change of each phase in a multiphase system. This method makes use of the scaling laws of the ...

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. ...

Fabrication and creep properties of eutectic-composition Al2O3/YAG/YSZ sintered composites
(Elsevier, 2021-12)
Three-phase alumina/YAG/yttria-stabilized cubic zirconia (YSZ) composites were fabricated by a solid-state reaction route starting from commercial powders of Al2O3, Y2O3 and monoclinic ZrO2. The final phases Al2O3, YAG and ...
