Synthesis and preliminary study of pure and Zr-doped YMnO3 compounds as Solid Oxide Fuel Cells electrode
(Elsevier Science Sa, 2017-06)
The Y1−xZrxMnO3series (0 ≤ x ≤ 0.30) has been studied to be used as possible SOFC electrode material. These compounds adopt a layered structure of hexagonal symmetry in which the manganese cations are located in trigonal ...
Antifungal applications for nano-additives synthesized with a bio-based approach
(IOP Publishing, 2020-03)
Filamentous fungi are microorganisms that cause deterioration of structural materials due to their ecological plasticity and vegetative functions. Functionalised sol-gel based products can be used to control this kind of ...
Spectroscopic and microscopic characterization of volcanic ash from puyehue-(Chile) eruption: Preliminary approach for the application in the arsenic removal
(ELSEVIER SCIENCE BV, 2013-08)
Volcanic ash from Puyehue Cordon Caulle Volcanic Complex (Chile), emitted from June 4 2011 and deposited in Villa La Angostura at ~ 40 km of the source, was collected and analyzed by Raman spectroscopy, optical and scanning ...
Kinetic and equilibrium adsorption of two post-harvest fungicides onto copper-exchanged montmorillonite: synergic and antagonistic effects of both fungicides’ presence
(Springer Heidelberg, 2019-01)
The simultaneous adsorption of both imazalil (IMZ) and thiabendazole (TBZ) fungicides in a Cu 2+ -exchanged Mt was studied in this work. Kinetic studies were used to determine the rate law which describes the adsorption ...
Chronic Lead Exposure Alters Mineral Properties in Alveolar Bone
(MDPI, 2021-06)
The objective of the present study was to investigate the effects of chronic lead exposure on the mineral properties of alveolar bone. For this purpose, female Wistar rats (n = 8) were exposed to 1000 ppm lead acetate in ...
Evaluation of different Ni–semiconductor composites as electrodes for enhanced hydrogen evolution reaction
(Royal Society of Chemistry, 2020-08)
The use of earth-abundant materials for designing efficient and stable electrocatalysts is of paramount importance to facilitate large-scale production of hydrogen. In this work we developed a new series of electrodes based ...
Entanglement of N-doped graphene in resorcinol-formaldehyde: Effect over nanoconfined LiBH 4 for hydrogen storage
(Pergamon-Elsevier Science Ltd, 2019-06)
N-doped graphene hydrogels were prepared by crosslinking graphene oxide with ethylenediamine. These materials presented 10 at. % nitrogen, as determined by X-ray photoelectron spectroscopy. N-doped graphene was entangled ...
Manufacture, characterization and proton irradiation effects of 12C and 13C thick targets
(Springer, 2021-04)
Abstract: Alternative sources of neutron production other than nuclear fission reactions are important priorities in medical and nuclear applications due to costs, safety and ease of operation. In this work, 12C and 13C ...
Infrared Spectroscopic Study of the Carbon Dioxide Adsorption on the Surface of Cerium-Gallium Mixed Oxides
(Elsevier Science, 2012-01)
In order to modified the acid-base properties of pure cerium dioxide, a series of ceria-based oxides doped with gallium(III) cations (from 5 to 50% mol/mol of Ga) was prepared by co-precipitation in basic aqueous solution ...
Preparation and Characterization of Bosentan Monohydrate/ε‐Polycaprolactone Nanoparticles Obtained by Electrospraying
(American Chemical Society, 2019-04)
The electrospraying technique provides nano and microparticles that can be used as drug delivery systems. The aims of this study were, firstly, to optimize the influent parameters of electrospraying for the manufacture of ...
