1. CONTRIBUIÇÃO TERMO-ENERGÉTICA DOS FECHAMENTOS TRANSPARENTES EM EDIFÍCIOS COMERCIAIS CLIMATIZADOS ARTIFICALMENTE EM SANTA MARIA-RS / THERMAL ENERGY CONTRIBUTION TO TRANSPARENT CLOSURE IN ARTIFICIALLY CONDITIONED COMMERCIAL BUILDINGS IN SANTA MARIA-RS
This paper analyzes the influence of the penetration of solar radiation through the transparent closure in consumption of energy for conditioning of the office buildings in the region of Santa Maria-RS, located in the bioclimatic Brazilian zone 2. To do this, simulations were performed in the computational program Design Builder, in a typical office environm

2. Re(I) complexes and TiO2 films in photoinduced molecular devices / Complexos de Re(I) e filmes de TiO2 em dispositivos moleculares fotoinduzidos
The thesis focus on two main topics: characterization of TiO2 films for Dye-sensitized solar cells, DSCs, and investigation on photochemical and photophysical properties of Re(I) polypyridyl complexes. Mesoporous TiO2 films were prepared by sol-gel method and by commercial oxide (P25, Degussa) and were characterized by XRD, SEM, B.E.T. and XPS. Both oxides w

3. Efficiency and form of external solar protector devices for office buildings: a study of cases in Curitiba-PR / Eficiência e forma de protetores solares externos em edifícios de escritórios: estudo de casos em Curitiba-PR
Shading devices are architectural elements which, when well projected and employed, can contribute to the reduction of the thermal gain in buildings and, consequently, the energy consumption necessary to cooling down hot air inside. Avoiding the direct incidence of sunlight through transparent windows, the shading devices contribute to the reduction of the g

4. "Electrochromic devices with solid polymeric electrolytes based on starch" / "Dispositivos eletrocrômicos com eletrólitos sólidos poliméricos à base de amido"
This dissertation presents the results of preparation and characterization of five electrochromic devices (DEC) composed of thin films of transition metal oxides, such as WO3, WO3:Ta, Nb2O5:Mo and NiOx as electrochromic layers and CeO2-TiO2 as a transparent counter-electrode. The electrolytes used in these devices were starch-based plasticized with glycerol

5. Very high growth rate chemical vapor deposition of single-crystal diamond
Diamond possesses extraordinary material properties, a result that has given rise to a broad range of scientific and technological applications. This study reports the successful production of high-quality single-crystal diamond with microwave plasma chemical vapor deposition (MPCVD) techniques. The diamond single crystals have smooth, transparent surfaces a
