Effect of pore generator on microstructure and resistivity of Sb(2)O(3)and CuO doped SnO(2)electrodes
(Springer, 2020-08-08)
Sb2O3 and CuO doped SnO2 ceramic electrodes could be an alternative to the ones currently used ones in the electrooxidation process of water pollutants. The rise of electrode surface by introducing a porogen agent on the ...
Compositional effects on the crosslink density of Ca–(Mg)–(Y)–Si–Al–oxyfluoronitride glasses
(Wiley, 2017-09)
The effects of fluorine and nitrogen substitution for oxygen in aluminosilicate glasses, effectively oxyfluoronitride (OFN) glasses, modified by calcium, calcium–yttrium or calcium–magnesium on thermal and physical/mechanical ...
An estimate of quartz content and particle size in porcelain tiles from young's modulus measurements
(Elsevier, 2017)
The influence of quartz particle size, weight content and firing temperature on the Young's modulus of porcelain tiles was studied. To simulate a porcelain tile microstructure, an albite glass matrix with added crystalline ...
Microstructure and photocatalytic activity of APS coatings obtained from different TIO2 nanopowders
(Elsevier, 2013-04)
In recent years, intense research has shown that thermal spray techniques, especially atmospheric plasma spraying (APS), can be used to obtain nanostructured TiO2 coatings with effective photocatalytic activity.
This ...
Magnetic complex permeability (imaginary part) dependence on the microstructure of a Cu-doped Ni–Zn-polycrystalline sintered ferrite
(Elsevier, 2020-07)
In this study, the effective complex magnetic permeability-imaginary part of a Cu doped-NiZn polycrystalline ferrite used as EMI suppressor has been quantitatively related to microstructural parameters. It has been observed ...
Densification of monomodal quartz particle beds by tapping
(Elsevier, 2008)
A study has been undertaken to determine how the mean particle size of monomodal quartz particle beds and the bed preparation method affect initial and final bed apparent density and the kinetics of densification by tapping. ...
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 ...
Delayed curvature and residual stresses in porcelain tiles
(Elsevier, 2013)
Most industrial porcelain tiles suffer changes in their curvature after firing: such process is known as delayed curvature. One of the hypotheses used to explain this phenomenon is based on the relaxation of residual ...
Polymorphism-Triggered Reversible Thermochromic Fluorescence of a simple 1,8-Naphthyridine
(ACS Publications, 2013-01-04)
The fluorescent behavior in the solid state of a naphthyridine-based donor–acceptor heterocycle is presented. Synthesized as a crystalline blue-emissive solid (Pbca), the compound can easily be transformed in its P21/c ...
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 ...
