Nanostructuring as a procedure to control the field dependence of the magnetocaloric effect
(Elsevier, 2017-01)
In this work, the field dependence of the magnetocaloric effect of Gd bulk samples has been enhanced through nanostructuring of the material. Nanostructuring consists in multilayers preparation by alternative rf-sputter ...

Correction of the Shape Effect on Magnetic Entropy Change in Ball Milled Fe70Zr30 Alloys
(Elsevier, 2018)
The field dependence of the magnetic entropy change (ΔSM) after mechanical alloying of Fe70Zr30 composition starting from high purity powders is studied. Samples with different shapes and different crystalline fraction X ...

Evolutionary Dynamics in Gene Networks and Inference Algorithms
(MDPI AG, 2015)
Dynamical interactions among sets of genes (and their products) regulate developmental processes and some dynamical diseases, like cancer. Gene regulatory networks (GRNs) are directed networks that define interactions ...

Precision and accuracy of stress measurement with a portable X-ray machine using an area detector
(International Union of Crystallography, 2017-02)
The use of portable X-ray stress analyzers, which utilize an area detector along with the newly adopted 'cosα' or full-ring fitting method, has recently attracted increasing interest. In laboratory conditions, these ...

Magneto-caloric effect in the pseudo-binary intermetallic YPrFe17 compound
(Elsevier, 2011)
We have synthesized the intermetallic YPrFe17 compound by arc-melting. X-ray and neutron powder diffraction show that the crystal structure is rhombohedral with View the MathML source space group (Th2Zn17-type). The ...

The effect of distributed exchange parameters on magnetocaloric refrigeration capacity in amorphous and nanocomposite materials
(AIP Publishing, 2012-02-17)
The temperature dependent magnetization of nanocomposite alloys has been fit with a modified Handrich-Kobe equation with an asymmetric exchange fluctuation parameter combined with the Arrott-Noakes equation. The two equations ...

Changes on the nanostructure of cementitius calcium silicate hydrates (C-S-H) induced by aqueous carbonation
(Kluwer Academic Publishers, 2012)
The nanostructure of the main binding phase of the hydrated cements, the calcium silicate hydrates (C-S-H), and their structural changes due to aqueous carbonation have been characterized using TEM, nitrogen physisorption, ...

Structural Relaxation in Fe(Co)SiAlGaPCB Amorphous Alloys
(Elsevier, 2014)
The structural relaxation of multicomponent Fe(Co)SiAlGaPCB amorphous alloys was investigated calorimetrically for annealed samples over a wide temperature range below the glass transition temperature. Upon heating, the ...
