1. Propriedades Estruturais e Espectroscópicas de Óxidos Mistos Argila/Hidróxido de Cobalto Tratados Termicamente / Structural and Spectroscopic Properties of Heat Treated Mixed Clay/Cobalt Hydroxide Oxides
Argilas são essencialmente silicatos hidratados de alumínio geralmente cristalinos denominados argilominerais, podendo conter ferro e magnésio. Podem conter ainda outros minerais, matéria orgânica e sais solúveis. Sob o ponto de vista físico-químico, as argilas podem ser consideradas como sistemas dispersos de minerais, nos quais predominam partícul

2. Planejamento e otimização de um método quimiluminescente para determinação de vitamina B12 usando um sistema fluxo-batelada / Design and Optimization of Chemiluminescent Method for Determination of Vitamin B12 in Drugs by Using a Flow-Batch System
The chemiluminescence (CL) of luminol-cobalt(II) reaction has been used in analytical systems for capillary electrophoresis, chromatography, -TAS (microTotal Analysis System), etc. Even with the diversity of applications, the steps of this reaction have not been completely elucidated and have been still a subject of research and controversy. Many wor

3. Estudos sobre sistemas de liberaÃÃo controlada da vacina antiaftosa e do cobalto II para uso veterinÃrio
On the first stage of our work, suspended virus O1 Campos (causing subtype of virus of foot-and-mouth disease) prepared by VALLÃE S/A was proposed as ligands to be bound to the Starch through covalents or by using carbodiimide in order to produce crosslinkings. The starch is oxidated by sodium metaperiodate 0,4 N in pH 4,5, that vicinal hidroxlicos groups a

4. Obtenção de insumos quimicos e farmaceuticos a partir da lignina hidrolitica de eucalipto
The conversion of hydrolytic eucalyptus lignin by hydrogenolysis, alkaline hydrolysis and oxidation was studied with the objective to produce low molecular weight substances. The lignin was obtained by acid hydrolysis of eucalyptus wood at Coalbra Company and at the Foundation of Industrial Technology (FTI) in Lorena. The lignin was submitted to hydrogenolys
