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 ...
Cool products for building envelope - Part I: Development and lab scale testing
(Elsevier, 2014-07)
The paper describes the methodology followed for the development of new cool products in order to widen the range of existing solutions both including coloured (even dark) materials and extending the application also to ...
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 ...
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 ...
Electrochemical Degradation of Reactive Black 5 using two-different reactor configuration
(Nature Research, 2020)
Novel Sb-doped SnO2 ceramic electrodes sintered at different temperatures, are applied to the degradation of Reactive Black 5 in both divided and undivided electrochemical reactors. In the undivided reactor the discoloration ...
Optimization of the technologycal properties of porcelain tile bodies containing rice straw ash using the deseign of experiments methodology
(Elsevier, 2016-11)
This study examines the effects of replacing fluxing and filler materials with rice straw ash (RSA) in manufacturing porcelain stoneware tile, using the design of experiments (DOE) methodology. The results of the ...
Nanobased coatings with improved NIR reflecting properties for building envelope materials: Development and natural aging effect measurement
(Elsevier, 2013-02)
A significant contribution to the reduction of the Urban Heat Island effect and cooling energy demand is given today by the so called cool materials for the building envelope with enhanced reflecting and emitting properties. ...
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 ...
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 ...
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 ...
