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 ...
Effect of TiO2 addition on the microstructure and nanomechanical properties of Al2O3 Suspension Plasma Sprayed coatings
(Elsevier, 2014-10)
Alumina–titania coatings are widely used in industry for wear, abrasion or corrosion protection components. Such layers are commonly deposited by atmospheric plasma spraying (APS) using powder as feedstock. In this study, ...

Eficiência energética na fabricação de placas cerãmicas mediante a utilização de óleo térmico
(APICER -(Associação Portuguesa das Indústrias de Cerâmica e de Cristalaria), 2014)
O processo de fabricação de placas cerâmicas consome uma grande quantidade de energia, maioritariamente energia térmica, que se obtém da combustão de gás natural. O aumento do custo deste combustível, assim como a situação ...
Energy saving in ceramic tile kilns: Cooling gas heat recovery
(Elsevier, 2014-04)
A great quantity of thermal energy is consumed in ceramic tile manufacture, mainly in the firing stage.
The most widely used facilities are roller kilns, fuelled by natural gas, in which more than 50% of the
energy input ...
Electrophoretic deposition of nanostructured TiO2/alginate and TiO2-bioactive glass/alginate composite coatings on stainless steel
(Maney Publishing, 2014-01)
Two alginate (Alg) based composite coatings on stainless steel AISI 316L substrates, one containing titania nanoparticles (n-TiO2) and another one a mixture (50/50 wt-%) of n-TiO2 and bioactive glass (BG), intended for ...

Influence of Salts on the Photocatalytic Degradation of Formic Acid in Wastewater
(MDPI, 2022-11)
Conventional wastewater treatment technologies have difficulties in feasibly removing persistent organics. The photocatalytic oxidation of these contaminants offers an economical and environmentally friendly solution. In ...
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 ...
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 ...
