13. STUDY OF THE AGGREGATION AND PHOTOBLEACHING DYNAMIC OF METHYLENE BLUE AND ORTO-TOLUIDINE BLUE AS REGARDS THEIR PHOTODYNAMIC EFFECTIVENESS / Estudo da dinâmica de fotodegradação e agregação das fenotiazinas azul de metileno e azul orto-toluidina com relação à eficiência fotodinâmica
Photodynamic therapy may be a viable alternative to treat localized infections, although to obtain a resourceful clinical application, parameters linked with photodynamic efficiency must be analyzed in order to achieve quantifiable results. The aims of this study were to investigate the aggregation dynamic of the photosensitizers methylene blue and orto-tolu

14. Estudo da morfologia e dinâmica molecular de filmes de MEH-PPV via espalhamento de raios-x de alto ângulo e ressonância magnética nuclear do estado sólido / Morphology and molecular dynamics of MEH-PPV films using wide-angle x-ray scattering and solid-state nuclear magnetic resonance
The morphology and dynamic of MEH-PPV films prepared by casting from toluene and chloroform were studied using Wide-Angle X-ray Scattering (WAXS) and Solid-State Nuclear Magnetic Resonance (NMR) techniques, respectively. Evidences of the increase in the aggregation were obtained by WAXS, which revealed a tendency of increasing in the molecular ordering upon

15. Nanoagregados baseados em ciclodextrinas em associação com a tetraciclina: caracterização fisico-química e avaliação antimicrobiana
Molecular self-assembling has been shown to be an efficient method to produce structures of few hundreds of nanometers in size. The supramolecular compounds made from (R)- cyclodextrin:tetracycline in aqueous solution were evaluated. The physicochemical interactions between â-cyclodextrin:tetracycline were characterized by dynamic light scattering (DLS), is

18. Differences in pressure and temperature transitions of proteins and polymer gels
Pressure-driven and temperature-driven transitions of two thermoresponsive polymers, poly(N-isopropylacrylamide) (pNIPAM) and poly(N-vinylisobutyramide) (pNVIBA)), in both a soluble linear polymer form and a cross-linked hydro-gel form, were examined by a dynamic light-scattering method and direct microscopic observation, respectively. Their behavior was com

19. Guaranteed cost fuzzy controllers for a class of uncertain nonlinear dynamic systems
Stability analysis and a systematic robust fuzzy control design for uncertain nonlinear systems with polytopic uncertainties are presented. The approach given uses the T-S fuzzy systems which are represented by a family of local uncertain linear systems with aggregation. The resulting fuzzy controller is a blending of state feedback gains obtained from a gua
