Mimicking natural fibrous structures of opals by means of a microemulsion-mediated hydrothermal method
(American Chemical Society, 2011-07)
Silica-based nanomaterials are of great interest because of their potential applications in constructing electronic and optoelectronic nanodevices. Especially significant are those that combine the properties of photonic ...
Opal phytolith and isotopic studies of "Restinga" communities of Maricá, Brazil, as a modern reference for paleobiogeoclimatic reconstruction
(Instituto Oceanográfico, 2015-07)
The Maricá restinga, located in the eastern part of the Rio de Janeiro State (Brazil), corresponds to one of the few remaining preserved areas of the state´s coastal plain. This paper reports on a study of the Maricá ...

Stopband tuning of TiO2 inverse opals for slow photon absorption
(Elsevier, 2017-03)
The effect of photonic photocatalysis was explored employing TiO 2 inverse opal structures. The degradation of methylene blue in aqueous phase was performed under visible light (λ = 450 nm) irradiation and showed an improved ...
Angle dependence in slow photon photocatalysis using TiO2 inverse opals
(Elsevier Science, 2018-03)
The slow photon effect was studied by means of the photocatalytic degradation of stearic acid over TiO2 inverse opals. The comparison of the degradation rates over inverse opals with those obtained over disordered structures ...
Characterization of titania inverse opals prepared by two distinct infiltration approaches
(Pergamon-Elsevier Science Ltd, 2018-05)
Titanium dioxide inverse opals were prepared by the typical method of infiltration with a liquid precursor (LP-IOs) and by an improved method in which the infiltration step is done with a suspension of TiO2 nanoparticles ...
Power system simulation algorithms for parallel computer architectures
(2012)
This paper discusses high-performance computing from the hardware, software, and algorithmic perspectives. The paper emphasizes on recent advancements in parallel algorithms for both Electro-Magnetic Transients and Transient ...
