Síntesis y caracterización de materiales en el sistema Ca1-xRxCu3Ti4O12 (R = Mg, Sr, Zn)
(2004)
Due to the high dielectric constant of CaCu3Ti4O12, there is interest in related material systems for high dielectric applications. Accordingly, becomes interesting to study the effect of some divalent cations replacing ...
Multiferroic properties of magnetic-ion- substituted oxide-electroceramic thin films
(2010)
Materials which possess electrical and magnetic coupling are of great interest for novel devices. In this thesis, BiFe1-xDxO3 (D= Co, Cr and Mn) material system were synthesized by solution route for various compositions, ...
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 ...
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 ...
Chalcogenide based (CuInS2/ZnS, CuInSe2/ZnSe) core/shell quantum dots for photodynamic therapy
(2015)
Strong luminescent CuInX2/ZnX (X=S,Se) core/shell quantum dots were synthesized by a novel nontoxic and inexpensive organometallic method in two simple steps of CuInS2 and CuInSe2 core formation and ZnS and ZnSe shell over ...
Síntesis y caracterización estructural y magnética del sistema Zn1-xCoxFe2O4
(2005)
Zno is a wide band gap semiconductor (Eg=3.6eV) with direct transition, thus magnetic ion substituted ZnO could be useful for spin-based applications. With this motivation, I investigated Zn1-xCoxFe2O4 including synthesis ...
