4. Fabricação e caracterização de nanopeneira polimericas / Fabricationan characterization of polimeric nanosieves
Sieves are microfiltration devices that in comparison with conventional membranes present a homogeneous pore size distribution and low roughness on the surface. These characteristics become them very attractive for use in processes of separation of particles by size. When the pores reach sub-micrometric dimensions and the sieves are made in biocompatible and

6. Capacitive microsensor for evaluation of the quality of automotive fuels. / Micro-sensor capacitivo para avaliação da qualidade de combustíveis automotivos.
This work proposes a capacitive sensor with interdigitated electrodes in order to evaluate the quality of automotive fuel. Interdigitated electrodes have some interesting features for this type of sensor. Among them, they increase the capacitance by having several capacitors in parallel, and by having a structure feasible to be manufactured by conventional m
