O papel da equivalência de contato na Cr-classificação de germes de aplicações Cr-estáveis
(Universidade Estadual Paulista (Unesp), 2011-02-22)
Neste trabalho estudaremos a equivalência de contato a fim de compreender seu papel na Cr-classificação dos germes Cr-estáveis, 0 ≤ r ≤ ∞. No caso r = ∞, este é um resultado clássico em Teoria de Singularidades provado por ...
On-line preconcentration and speciation analysis of Cr(III) and Cr(VI) using baker's yeast cells immobilised on controlled pore glass
(Elsevier B.V., 2005-08-08)
A study was undertaken to evaluate Saccharonzyces cerevisiae as a substrate for the biosorption of Cr(III) and Cr(VI) aiming to the selective determination of these species in aqueous solutions. The yeast cells were ...

Electrochemical behaviour of thermally sprayed Cr3C2-NiCr coatings in 0.5 M H2SO4 media
(Kluwer Academic Publ, 2002-11-01)
The electrochemical behaviour of coated Cr3C2-NiCr steel in aerated 0.5 M H2SO4 solution was studied by means of electrochemical a.c. and d.c. measurements. A complete structural characterization of the coated steel before ...

USO DE FeS2 EN LA ESTABILIZACIÓN QUÍMICA DEL CROMO EN ESCORIAS SIDERÚRGICAS
(2011-11-14)
Chromium containing slags from stainless steelmaking may eventually be leached by acidic environments, therefore they should be treated before being stockpiled or have contact with the environment. In this work, synthetic ...
