Magnetic and structural characterization of solid solution NixZn(1-x)Fe2O4 (x = 0.5 AND x = 1) synthesized by high energy ball milling
(2013)
Mechanochemical reactions of NiO, ZnO, and α-Fe2O3 were carried out in a planetary mill to produce Nickel ferrite (NiFe2O4) and Nickel-Zinc ferrite (Ni0.5Zn0.5Fe2O4) nanocrystallites. All measurements were made at room ...
Fabricación y caracterización de películas de dióxido de vanadio (VO2) depositadas por sputtering con corriente continua pulsada
(2011)
Thin films of vanadium dioxide were grown on glass and sapphire substrates by the pulsed-dc sputtering technique. This compound is of great interest because it exhibits a semiconductor (monoclinic phase) to metal (tetragonal ...
Estudio experimental del efecto de la impureza magnética, Pr, EN, MgB2
(2015)
This paper consists of an experimental study of the effect of magnetic and non- magnetic impurities in a superconductor MgB2 polycrystalline sample. There are many researches that explain that MgB2 can be easily prepared ...
High energy density xLi2MnO3-(1−x)LiMn0.5Ni0.5O2 cathode system for lithium-ion rechargeable batteries
(2013)
In this work xLi2MnO3-(1-x)LiNi0.5Mn0.5O2 (x = 0.3 and 0.5) layered cathode materials were synthesized by the co-precipitation route. The synthesized powders were annealed at 950 °C for 12 h in air to get the desired ...
Synthesis and characterization of Fe3O4/ZnO and Fe3O4/ZnMnS core-shell heterostructured nanoparticles
(2010)
Currently, core-shell heterostructured nanosystems are emerging as next-generation materials due to their potential multifunctionalities in contrast with the more limited single-component counterparts. Systematic investigation ...
Synthesis and multiferroic properties of Bi3.4M0.6Ti3O12/CoFe2O4 (M= La3+ and Sm3+) multilayer structures
(2013)
In search of new multiferroic materials Bi4-xMxTi3O12 and CoFe2O4 alternate layers were investigated. For this work, multilayer films of Bi3.4M0.6Ti3O12 with M = La3+, Sm3+ and CoFe2O4 were synthesized by chemical solution ...
Estudio de la transición de fase metal-semiconductor en dióxido de vanadio
(2015)
In this thesis we made a study about the Metal-Insulator phase transition with the purpose to determine, particularly, the parameters to play a important rol in the transition. For this we made a study of theories or models ...
Emission heights and possible radius-to-intensity mapping in pulsar magnetospheres
(2019-06-07)
Pulsars are highly magnetized, rapidly spinning neutron stars. One of their most notable characteristics is that they emit narrow beams (in the form of a cone) of electromagnetic (EM) radiation from the space above the ...
Effect of the incorporation of defects in ZnO nanocrystals on the generation of reactive oxygen species for applications in photodynamic therapy
(2015)
Photodynamic therapy (PDT) is an alternative to traditional cancer treatments. This
approach involves the use of photosensitizer (PS) agents and their interaction with light. As
a consequence, cytotoxic reactive oxygen ...
Synthesis and characterization of CuAlO2 thin films by reactive rf magnetron sputtering
(2010)
This work presents a comparative study on optical and electrical properties of CuAlO2 thin films on sapphire (0001) substrates deposited with two different growth conditions using reactive RF-magnetron sputtering technique ...
