On the existence of ordered phases of encapsulated diamondoids into carbon nanotubes
We have investigated some diamondoids encapsulation into single walled carbon nanotubes (with diameters ranging from1.0 up to 2.2 nm) using fully atomistic molecular dynamics simulations. Diamondoids are the smallest ...
Calcium modified lead titanate/poly-ether-ether-ketone composite for acoustic emission sensors
Composites made of calcium modified lead titanate ceramic powder and poly (ether-ether-ketone) high performance polymer matrix were prepared in the film form using a hot press. The acoustic and electromechanical properties ...
Artificial soil for earthworm growth: initial stage for chemical modification of charcoal by earthworm.
(In: INTERNATIONAL BIOCHAR CONFERENCE, 3., 2010, Rio de Janeiro. Processing from terra preta de índios to the whole world. Brasília, DF: Embrapa: MAPA, 2010., 2012)
The influence of the mixing time in the rheological behavior of cement pastes
Rheology has the purpose to study the flux and deformation of materials when submitted to some tension or outer mechanical solicitation. In practice, the effective scientific field broached by rheology is restricted only ...
Characterization Of The Residue From Double Alginate Extraction From Sargassum Filipendula Seaweed
(Aidic Servizi SRLMilano, 2016)
Nitrification processes in groundwaters evidenced by modification on the U contents and U-234/U-238 activity ratios
(Computational Mechanics Publications Ltd, 1998-01-01)
Groundwaters from the Botucatu-Piramboia aquifer system located at the Parana sedimentary basin in Brazil and sampled at Ribeirao Preto city, São Paulo State, were chemically and isotopically analysed, with the aim of ...
Methanol oxidation on PtRu/C electrocatalysts prepared by a microemulsion method
PtRu/C nanocatalysts were prepared by a microemulsion method using different values of water/surfactant molar ratio in order to get different particle sizes. Crystallite sizes and structural properties were determined by ...
Brazilian experience with the medium-term multi-organ bioassay: Scientific and regulatory developments
In 1996 the Brazilian Institute for the Environment (IBAMA) officially adopted a variation of the multiorgan initiation-promotion DMBDD bioassay as a valid source of evidence of the carcinogenic potential of pesticides. ...
Biomimetic calcium phosphates-based coatings deposited on binary Ti-Mo alloys modified by laser beam irradiation for biomaterial/clinical applications
Biomimetic Method has been widely used to prepare calcium phosphate coatings on Ti and its alloys. This modification is based on a Synthetic/simulated Body Fluid (BSF) which facilitates the mimicking of the biological ...
