Comparative studies of hybrid functional materials based on different carbon structures decorated with nano-magnetite. Suitable application as platforms for enzyme-free electrochemical sensing of hydrogen peroxide
Venosta, Lisandro Francisco; Bracamonte, María Victoria; Rodríguez, Marcela Cecilia; Jacobo, Silvia Elena; Bercoff, Paula Gabriela (2017)A simple synthesis procedure was designed to obtain hybrid materials based on graphite structures and magnetite nanoparticles. These new structures were characterized using different techniques. The results show that the ... -
Gadolinium substitution effect on the thermomagnetic properties of Ni ferrite ferrofluids
Jacobo, Silvia Elena; Arana, Mercedes; Bercoff, Paula Gabriela (2016)This work is focused on the characterization of Ni-ferrite nanocrystals and their subsequent doping with Gd, in an attempt to explore Gd inclusion in the thermomagnetic properties of prepared ferrofluids. Spinel ferritesNiFe2O4, ... -
Lithium dual uptake anode materials : crystalline Fe3O4 nanoparticles supported over graphite for lithium-ion batteries
Bracamonte, María Victoria; Primo, Emiliano Nicolás; Luque, Guillermina Leticia; Venosta, Lisandro Francisco; Bercoff, Paula Gabriela; Barraco Díaz, Daniel Eugenio (2017)Graphite, the usual anode material for current technology of lithium ion batteries (LIB), has great advantages and its processing is widely known and industrially feasible. For improving the anode’s capacity, recent research ... -
Multi-characterization of electron-induced defects in highly oriented pyrolytic graphite
Bajales Luna, Noelia; Avila, Milagros; Galván Josa, Víctor Martín; Bercoff, Paula Gabriela (2016)Engineering the properties of materials through defects is at the forefront of research in Materials Science. Here, we investigate the defects produced on highly oriented pyrolytic graphite (HOPG) samples irradiated with ... -
Structural and magnetic influence of yttrium-for-iron substitution in cobalt ferrite
Haïk Dunn, Isaac Gaston Christian; Jacobo, Silvia Elena; Bercoff, Paula Gabriela (2017)Yttrium-substituted cobalt ferrites of nominal composition CoY x Fe 1.98-xO4 , x=0; 0.1; 0.2; 0.3, were prepared using the sol-gel combustion method. A slight iron deficiency in the formulation was designed in order to ... -
Structural and magnetic properties of nanocrystalline Bi1-xLaxFeO3 (0.0 ≤ x ≤ 0.4) synthesized by a mechanochemical route
Cristóbal, Adrián Alberto; Ramos, Cinthia Paula; Conconi, María Susana; Bercoff, Paula Gabriela; Botta, Pablo Martín (2017)Bi1-xLaxFeO3 (0.0 ≤ x ≤ 0.4) powders were prepared by means of a solid acid-base reaction induced by mechanochemical energy. Bi, La and Fe chlorides were high-energy ball-milled with NaOH, yielding a mixture of Bi1-xLaxFeO3 ...
