Production of biodiesel from roasted chicken fat and methanol: free catalyst
(2014)
"Transesterification reactions free of catalyst between roasted chicken fat with methanol were carried out in a batch reactor
in order to produce biodiesel to temperatures from 120°C to 140°C. Parameters related to the ...
Enlarged sheet of ZnS(en)0.5 hybrid semiconductors with photocatalytic activity
(2015)
"Sheets of ZnS(en)0.5 hybrid semiconductors were prepared by the precipitation method in an ethylenediamine–water solution and it was enlarged by varying the aging at a long period time. The characterization of the hybrid ...
A functional assembly of SiO2 nanospheres/graphene oxide composites
(Elsevier, 2015)
"A novel assembly of SiO2 nanospheres functionalized on graphene oxide (GO) sheets was prepared by a one-step microwave-hydrothermal method. The nanocomposites were well characterized and investigated to study their Rhodamine ...
Evaluation of vascular tone and cardiac contractility in response to silver nanoparticles, using Langendorff rat heart preparation
(Elsevier, 2017)
"Silver nanoparticles (AgNPs) have been widely used because of their antimicrobial properties. However, several reports suggest that AgNPs exposure promote cardiac effects that involve nitric oxide (NO) and oxidative stress ...
Comparison of two synthesis methods on the preparation of Fe, N-Co-doped TiO2 materials for degradation of pharmaceutical compounds under visible light
(Elsevier, 2017)
"In this work, we report the synthesis, characterization and photocatalytic evaluation of visible light active iron-nitrogen co-doped titanium dioxide (Fe3+-TiO2?xNx) nanostructured catalyst. Fe3+-TiO2?xNx was synthesized ...
Synthesis and magnetocaloric characterization of rapidly solidified ErMn2 melt-spun ribbons
(Elsevier, 2017)
"We have fabricated melt-spun ribbons of nominal composition ErMn2 and studied their phase constitution and magnetocaloric (MC) properties by X-ray diffraction, scanning electron microscopy (SEM), magnetization and heat ...
Flexible rewritable organic memory devices using nitrogen-doped CNTs/PEDOT:PSS composites
(Elsevier, 2017)
"Nonvolatile rewritable organic memory devices based on poly(3,4-ethylene dioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) and nitrogen doped multi-walled carbon nanotube (NCNT) nanocomposites were fabricated on glass ...
Modeling and optimization of a photocatalytic process: degradation of endocrine disruptor compounds by Ag/ZnO
(Elsevier, 2017)
"Artificial neural network (ANN) modeling was applied to study the photocatalytic degradation of bisphenol-A. The operating conditions of the Ag/ZnO photocatalyst synthesis and its performance were simultaneously modeled ...
Study of the presence of spherical deformations on the Al top electrode due to electroforming in rewritable organic resistive memories
(Royal Society of Chemistry, 2017)
"Physical deformations are observed at the top electrodes during the electroforming process in Al/PEDOT: PSS + nitrogen doped multiwalled carbon nanotube (N-MWCNTs)/Al rewritable resistive memory devices. These physical ...
Hydrogen production by tailoring the brookite and Cu2O ratio of sol-gel Cu-TiO2 photocatalysts
(2017)
"Cu-TiO2 photocatalysts were prepared by the sol-gel method. Copper loadings from, 1.0 to 5.0 wt % were used. The materials were annealed at different temperatures (from 400 to 600 °C) to study the formation of brookite ...
