1. Absorção de multi-fótons em polímeros e resinas poliméricas: espectroscopia não linear e microfabricação / Multi-photon absorption in polymers and polymeric resins: nonlinear spectroscopy and microfabrication
Nesta tese, estudamos o processo de absorção multifotônica em polímeros e resinas poliméricas, abordando tanto aspectos fundamentais quanto aplicados. Com relação aos aspectos fundamentais, estudamos processos de absorção multifotônica (absorção de dois, três e quatro fótons) no polímero conjugado MEH-PPV (poly(2-methoxy-5-(2´-ethylhexyloxy)-

2. Análise multi-espectral dos eventos cíclicos de Carinae / Multi-spectral analysis of the cyclic events of Eta Carinae
In this thesis, a multi-wavelength study on the cyclic events of Eta Carinae was performed. The presence of a hole in the polar region of the Homunculus was confirmed by the velocity maps of the [Fe II] 12567 line. The blue-shifted component of the He I 10830, detected towards the NW lobe, was mapped and it is in the equatorial plane. It was observed that wi

3. Caracterização elétrica de células solares de tripla tecnologia de matérias e sensores / Electrical characterization of triple junction solar cells - GAINP/GAAS/GE
Triple junction solar cells use a combination of semiconductor materials to more efficiently capture photons in the range of 300nm to 1800nm of sun solar spectrum. Minimum average conversion efficiency AM0 for first generation TJ solar cell for space use is 26,0%. The GaInP, GaAs and Ge were select because of their collective ability to match bandgap energie
