Adiabatic magnetocaloric effect in Ni50Mn35In15 ribbons
(2016-11)
"Heusler-type Ni-Mn-based metamagnetic shape memory alloys (MetaMSMAs) are promising candidates for magnetic refrigeration. To increase heat exchange rate and efficiency of cooling, the material should have a high ...
Enhanced refrigerant capacity in two-phase nanocrystalline/amorphous NdPrFe17 melt-spun ribbons
(2014-05)
"he magnetocaloric properties of NdPrFe17 melt-spun ribbons composed of nanocrystallites surrounded by an intergranular amorphous phase have been studied. The nanocomposite shows two successive second-order magnetic phase ...
Elastocaloric effect in Ti-Ni shape-memory wires associated with the B2 ↔ B19' and B2 ↔ R structural transitions
(2016-02)
"We have studied the elastocaloric properties of Ti-Ni shape-memory wires subjected to specific heat treatments to decouple the B2 <-> R transition from the B2 <-> B19' one. The entropy values at moderate stresses (similar ...
Giant magnetocaloric effect in melt-spun Ni-Mn-Ga ribbons with magneto-multistructural transformation
(2014-01)
"Magnetic refrigeration based on the magnetocaloric effect (MCE) may provide an energy-efficient and environment-friendly alternative to the conventional gas compression/expansion cooling technology. For potential applications, ...
Modelling adsorption isotherms of binary mixtures of carbon dioxide, methane and nitrogen
(2011)
"A molecular-based approach for modelling mixtures adsorbed onto solid surfaces using the Statistical Associating Fluid Theory for Potentials of Variable Range (SAFT-VR) for three- and two-dimensional systems is presented ...
Magnetic and electrical properties of nitrogen-doped multiwall carbon nanotubes fabricated by a modified chemical vapor deposition method
(2015)
"Chemical vapor deposition (CVD) is a preferential method to fabricate carbon nanotubes (CNTs). Several changes have been proposed to obtain improved CNTs. In this work we have fabricated nitrogen-doped multiwall carbon ...
Effect of the thickness of insulator polymeric films on the memory behavior: the case of the polymethylmethacrylate and the polystyrene
(2011)
"The effect of thickness variation on the memory behavior of the polymethylmethacrylate-(PMMA)-based devices has been investigated. The PMMA film thicknesses have been varied between 5 to 300 nm, and we have found that the ...
