1. Removal of Orange G Dye by Manganese Oxide Nanostructures
Two types of manganese oxide were investigated for the removal/degradation of Orange G (OG) dye in aqueous solution. One manganese oxide (pyrolusite) was obtained commercially and the other (birnessite) was prepared according to the polyol method by means of the oxidation of MnII hydroxide by H2O2. Both materials were characterized by X-ray diffraction (XRD)

2. Usando um calorímetro isoperibólico no laboratório didático de uma forma diferente / Using an isoperibol calorimeter at didactical laboratory in a different way
Esse trabalho consiste na utilização de um calorímetro isoperibólico em laboratório didático de química no nível superior, para se estudar aspectos mais amplos de alguns processos, que não os energéticos. Como se sabe, o calorímetro é o principal instrumento da primeira lei da termodinâmica e, como tal, presta-se, normalmente, para se obter a va

3. APLICAÇÃO DE PROCESSOS OXIDATIVOS AVANÇADOS HOMOGÊNEOS E HETEROGÊNEOS NA DEGRADAÇÃO DE EFLUENTES DE CURTUME
This study investigated the application of advanced oxidative processes for the homogeneous and heterogeneous degradation of a tanning effluent. The catalytic activity of a solid oxide containing manganese was evaluated in the heterogeneous systems. The experiments were performed in a photocatalytic batch reactor in laboratory scale. The solid used was the c

4. "Developments of carbn-dispersed electrocatalysts for cathodes of alkaline fuel cells" / "Desenvolvimento de eletrocatalisadores dispersos para o cátodo de células a combustível alcalinas"
The oxygen reduction reaction (ORR) was studied on electrodes formed by Pt monolayers deposited on different metallic substrates, and on carbon-supported electrocatalysts composed by PtM/C (M = V, Cr e Co) and AgPt/C alloys, and on different Mn oxides (Mn3O4/C, Mn2O3/C and MnO2/C) in alkaline electrolyte. The experimentally measured electrocatalytic activiti
