Magnetovolume and magnetocaloric effects in Er2Fe17
(2012-11)
"Combining different experimental techniques, investigations in hexagonal P6(3)/mmc Er2Fe17 showremarkable magnetovolume anomalies below the Curie temperature, T-C. The spontaneous magnetostriction reaches 1.6 x 10(-2) at ...
Caloric effects induced by magnetic and mechanical fields in a Ni50Mn25-xGa25Cox magnetic shape memory alloy
(2011-05)
"We have studied the elastocaloric effect in a Co-doped Ni-Mn-Ga magnetic Heusler shape memory alloy in the vicinity of its martensitic transition. Measurements of the length change as a function of temperature have been ...
Wave transmission through periodic, quasiperiodic, and random one-dimensional finite lattices
(2013-02)
"The quantum mechanical transmission probability is calculated for one-dimensional finite lattices with three types of potentials: periodic, quasiperiodic, and random. When the number of lattice sites included in the ...
Two-dimensional tunneling in a SQUID
(2010-11)
"Traditionally quantum tunneling in a superconducting quantum interference device (SQUID) is studied on the basis of a classical trajectory in imaginary time under a two-dimensional potential barrier. The trajectory connects ...
Synthesis, characterization, and sensor applications of spinel ZnCo2O4 nanoparticles
(MDPI, 2016-12)
"Spinel ZnCo2O4 nanoparticles were synthesized by means of the microwave-assisted colloidal method. A solution containing ethanol, Co-nitrate, Zn-nitrate, and dodecylamine was stirred for 24 h and evaporated by a microwave ...
Obtención y caracterización de nanopartículas de plata soportadas en fibra de algodón
(2013)
"En este trabajo se prepararon biocompositos de nanopartículas de plata utilizando fibra de algodón como soporte y Camellia sinensis como agente reductor. Para la preparación de los biocompositos primero se llevó a cabo ...
Understanding the ion-induced elongation of silver nanoparticles embedded in silica
(2017-04)
"In this work we have studied the elongation of silver nanoparticles irradiated with 40 MeV Bromine ions by means of in situ optical measurements, transmission electron microscopy and molecular dynamics simulations. The ...
Texture-induced enhancement of the magnetocaloric response in melt-spun DyNi2 ribbons
(2013-10)
"The magnetocaloric properties of melt-spun ribbons of the Laves phase DyNi2 have been investigated. The as-quenched ribbons crystallize in a single-phase MgCu2-type crystal structure (C15; space group Fd (3) over barm) ...
Identification of individual and few layers of WS2 using Raman Spectroscopy
(2013-04)
"The Raman scattering of single-and few-layered WS2 is studied as a function of the number of S-W-S layers and the excitation wavelength in the visible range (488, 514 and 647 nm). For the three excitation wavelengths used ...
Conventional and inverse elastocaloric effect in Ni-Fe-Ga and Ni-Mn-Sn ribbons
(Elsevier, 2017-02)
"Magnetic shape memory Ni55Fe16Ga29 and Ni50Mn40Sn10 melt spun ribbons have been characterized by thermomechanical and mechanical analysis. Martensitic transformation temperatures show an abnormal tendency to decline under ...
