1. Aplicações de enzimas na síntese e na modificação de polímeros
Enzymes are biological catalysts that offer great potential for use in the synthesis and modification of polymers, being more specific and greener than chemical catalysts. In this work, enzymes from the classes of hydrolases (lipase, cutinase and protease) and of oxidoreductases (horseradish peroxidase, manganese peroxidase and laccase) were identified as th

2. Estudo fotoluminescente de filmes de policarbonato(PC) e poli(9- vinicarbazol) (PVK) dopados com complexo de európio / Photoluminescent study of polycarbonate (PC) and poly(9-vinylcarbazole) (PVK) doped films with europium complex
Polímeros dopados com complexos de terras raras são materiais vantajosos na produção de filmes para várias aplicações no campo da luminescência. Neste estudo de polímeros luminescentes obtidos a partir de polímeros como o policarbonato (PC) e o poli(9-vinilcarbazol) (PVK), os filmes dopados com o complexo diaquatris (tenoiltrifluoroacetonato) de eu

3. Parametros para a escolha de superficies translucidas visando o conforto termico e visual na edificação / Parameters for selecting translucent susfaces focusing on the thermal and visual comfort on the building
This paper is directed towards translucent glasses and alveolar polycarbonates due to the lack of extensive research in this field. Nonetheless, these materials have been ostensively used in Europe and United States. In Brazil, translucent glasses and alveolar polycarbonates have been increasingly applied to building facades since the decade of 90s as a no

4. DLC-Si protective coatings for polycarbonates
In this work, a-C:H:Si (DLC-Si) films were produced onto crystalline silicon and polycarbonate substrates by the rf-PACVD technique from gaseous mixtures of CH4 + SiH4 and C2H2 + SiH4. The effects of self-bias and gas composition upon mechanical and optical properties of the films were investigated. Micro-hardness, residual stress, surface roughness and refr

5. Caracterização otica em materiais transparentes e sua relação com o confortoambiental em edificação
In this work, the characterization and analysis of the solar radiation transmission through transparent materials appropriated for buildings façades is presented. Materials such as reflective sputtered glasses, polycarbonates and commercial polymeric films for solar control on float glass are studied. The electrocromic glass type, promissory new material un
