Technological proposals for recycling industrial wastes for environmental applications
(MDPI, 2014)
A two-fold objective is proposed for this research: removing hazardous and unpleasant wastes and mitigating the emissions of green house gasses in the atmosphere. Thus, the first aim of this work is to identify, characterize ...

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. ...

Does grain size have an influence on intrinsic mechanical properties and conduction mechanism of near fully-dense boron carbide ceramics?
(Elsevier, 2019)
This work is concentrated on getting a reply to the following question: how does the grain size of boron carbide specimens influence on their mechanical and electrical response? It is a common issue that both essential ...

Influence of Mn on the magnetocaloric effect of nanoperm-type alloys
(AIP Publishing, 2010)
In this paper, the influence of the Mn content on the magnetocaloric response of ribbon-shaped amorphous samples of Fe80−xMnxB20 x=10, 15, 18, 20, and 24 , has been studied. For this purpose, the temperature and field ...

The magnetocaloric effect and critical behavior in amorphous Gd 60Co 40-xMn x alloys.
(AIP Publishing, 2012)
The amorphous alloys Gd60Co40−xMnx (x = 0, 5, 10, 15) were prepared by melt spinning. The Curie temperature,T c, increases monotonously with Mn addition, ranging from 198 K for x = 0 to 205 K for x = 15, while the maximum ...

Performance improvement in olive stone's combustion from a previous carbonization transformation
(Elsevier, 2018-09)
Under the framework of circular economy, agricultural wastes are an interesting carbon-based feedstock for thermal energy and power generation. Their use could extend the availability of biomass-based fuel and, at the same ...

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 ...
