(Universidade Tecnológica Federal do ParanáFrancisco Beltrao, 2011-12-06)
Due to the great consumption of pasteurized milk by the population of this region, it is necessary to evaluate the microbiological and physical-chemical quality of this product. The aim of this study is to evaluate some ...
Physical-chemical and thermodynamic analyses of ethanol steam reforming for hydrogen production
(Asme-amer Soc Mechanical Eng, 2014)
Physical-chemical properties of nanocomposites based on poly(3-hydroxybutyrate-co-3-hydroxyvalerate) and titanium dioxide nanoparticles
(Iop Publishing Ltd, 2018)
Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) was reinforced with titanium dioxide (TiO2) in concentrations of 1.0%, 2.5% and 5.0% (m/m) to produce nanocomposites by the solvent casting technique. TiO2 was synthesized ...
Physical-chemical and thermodynamic analyses of steam reforming of ethanol to hydrogen production
(2005-12-01)
The steam reforming is one of most utilized process of hydrogen production because of its high production efficiencies and its technological maturity. The use of ethanol for this purpose is a interesting option because ...
Prediction of the combustion process in fluidized bed based on physical-chemical properties of biomass particles and their hydrodynamic behaviors
(Elsevier B.V., 2014-08-01)
The utilization of biomass in fluidized bed reactors is due to alternatives created by the carbon credit market and to environmental concerns. This fact calls for an accurate determination of physical-chemical properties ...
Construction and test of low cost X-ray tomography scanner for physical-chemical analysis and nondestructive inspections
(2009-11-27)
