1. Determinação de parâmetros cinéticos em fluxo com câmara de gradiente e deteção espectrofotométrica: aplicação à reação entre o violeta de cristal e o ião hidróxido
A didactic experiment is proposed aimed to extend the Flow Injection Analysis (FIA) based methodology to the area of physical chemistry/chemical reactors for undergraduate labs. Our prime objective was to describe the use of a gradient chamber for determination of the rate constant for the reaction between crystal violet and the hydroxide ion. The study was

2. Imobilização de enzimas em suportes cromatográficos: uma ferramenta na busca por substâncias bioativas
The development and characterization of bioreactors or IMER (immobilized enzyme reactors) as research tools are important in the scope of medicinal chemistry and constitute an alternative for the rational development of drugs. This approach does not require highly purified enzymes or a great amount of protein, but increase the enzymatic stability against hea

3. AVALIAÇÃO DA INFLUÊNCIA DO MATERIAL SUPORTE E CARACTERIZAÇÃO DA DIVERSIDADE MICROBIANA DE REATORES ANAERÓBIOS PARA O TRATAMENTO DE EFLUENTE DE ABATEDOURO
The effluent generated in abattoirs has a high concentration of organic matter and need treatment before being discarded in the water bodies. Anaerobic biological filters are considered a good technique for the treatment of industrial effluents; however, choosing the correct support media is extremely important to ensure the success of the reactor. In the sa

4. Modelo computacional bidimensional para escoamentos gasosos com transferência de calor em um reator tipo CVD / Computational model 2D for gaseous flow with heat transfer for a reactor type CVD
Nesta dissertação foi realizada a elaboração de um prototipo para a simulação numérica computacional do escoamento gasoso, com transferência de calor, aplicado ao reator tipo CVD, existente no Laboratório Associado de Sensores e Materiais (LAS) do Instituto Nacional de Pesquisas Espaciais (INPE). Inicialmente, no intuito de definir qual o melhor tip

5. Filmes de diamante CVD dopado com boro. Parte I . Histórico, produção e caracterização
This review presents a brief account concerning the production, characterization and evolution of the knowledge in the area of diamond and boron-doped diamond films. The most important methods used for the growth of these films, such as chemical vapor deposition and high pressure/high temperature systems, as well as the several kinds of reactors which can be

6. Modelo computacional bidimensional para escoamentos gasosos com transferência de calor em um reator tipo CVD / Computational model 2D for gaseous flow with heat transfer for a reactor type CVD
In this work was made the elaboration of an prototype for the computational numerical simulation of the gaseous ow, with transfer heat, applied to the reactor type CVD, existing in the Laboratorio Associado de Sensores e Materiais (LAS) of the Instituto Nacional de Pesquisas Espaciais (INPE). Initially, we intention was to dene which the best type of mesh to

7. Microondas em síntese orgânica
The application of microwave heating to organic synthesis is presented in a concise manner. Issues such as the history of the microwave oven, dielectric heating, reactions techniques (dry reactions, MORE chemistry), domestic ovens, microwave reactors, microwave effect and control of selectivities are discussed. Selected examples from the literature showed fa
