Electrophoretic deposition of nanostructured-TiO2/chitosan composite coatings on stainless steel
(Royal Society of Chemistry, 2013-03)
Novel chitosan composite coatings containing titania nanoparticles (n-TiO2) for biomedical applications were developed by electrophoretic deposition (EPD) from ethanol–water suspensions. The optimal ethanol–water ratio was ...
Study of the Stereoselectivity of the Nucleophilic Epoxidation of 3-Hydroxy-2- methylene Esters
(Elsevier, 2013-01)
The diastereoselectivity of the nucleophilic epoxidation of 3-hydroxy-2-methylene esters has been studied. The 3-hydroxy-2-methylene esters were obtained through a Morita–Baylis–Hillman reaction. The resulting epoxyesters ...
Fracture toughness and temperature dependence of Young's modulus of a sintered albite glass
(Elsevier, 2013-03)
Albite glass is an important component in many ceramic compositions, often used as liquid phase during the sintering process. Nevertheless, in spite of its almost ubiquous presence in the final microstructure of these ...
Stereoisomerization of α-hydroxy-β-sulfenyl-α,β-dimethyl naphthoquinones controlled by nonbonded sulfur–oxygen interactions
(Elsevier, 2013-03)
The anti α-hydroxy-β-sulfenyl-α,β-dimethyl naphthoquinones isomerize in basic media into syn/anti mixtures of isomers, giving the syn isomer as the major product. Conversely, anti α-hydroxy-β-alkoxy-α,β-dimethyl naphthoquinones ...
Modeling of Drying Curves of Silica Nanofluid Droplets Dried in an Acoustic Levitator Using the Reaction Engineering Approach (REA) Model
(Taylor & Francis, 2013)
The use of nanoparticles has become of great interest in different industrial applications. The spray drying of nanofluids forms nanostructured grains, preserving the nanoparticle properties. In this work, individual ...
Development of a WD-XRF analysis method of minor and trace elements in liquid petroleum products
(Elsevier, 2013)
This paper describes a methodology for the analysis of minor and trace elements in liquid petroleum products, with varying oxygen content between 0% w/w and 3.4% w/w and varying C/H ratio between 7 and 9, by wavelength-dispersive ...
Influence of the feedstock characteristics on the microstructure and properties of Al2O3–TiO2 plasma-sprayed coatings
(Elsevier, 2013-04)
Atmospheric plasma spraying (APS) is an interesting technique to obtain nanostructured coatings due to its versatility, simplicity and relatively low cost. However, nanometric powders cannot be fed into the plume using ...
Synthesis and electrochemical behavior of ceramic cation-exchange membranes based on zirconium phosphate
(Elsevier, 2013-05)
Cation-exchange membranes made exclusively from ceramic materials have been synthesized by means of the impregnation of microporous ceramic supports with zirconium phosphate. Changes in the pore size distribution and total ...
Interaction of the chromium–iron black pigment with porcelanised stoneware
(Elsevier, 2013-09)
A study has been undertaken on the interaction between the (Fe,Cr)2O3 black pigment and an industrial porcelanised stoneware composition at its firing temperature. The results indicate that the glassy phase that forms ...
Correlation of thermal conductivity of suspension plasma sprayed yttria stabilized zirconia coatings with some microstructural effects
(Elsevier, 2013)
Yttria-stabilized zirconia (3YSZ) coatings were successfully obtained by suspension plasma spraying. The coatings present generally two-zones-microstructure comprising nanostructured zones contributed by unmolten, partially ...
