1. Structural Study of Wheat Gliadin in Different Solvents by Spectroscopic Techniques
Physicochemical properties of gliadin in different solvents (dimethyl sulfoxide (DMSO), H2O, and aqueous ethanol) and pH (9.8, 6.8, and 1.2) were investigated using dynamic light scattering (DLS), zeta potential (ZP), and attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR). Gliadin-DMSO and gliadin-deionized water (H2O) (pH 9.8) s

2. Improving Photoluminescence Quantum Yield of CdTe Quantum Dots Using a Binary Solvent (Water + Glycerin) in the One-Pot Approach Synthesis
The present work describes the comparison of the optical and structural properties between CdTe quantum dots (QD) synthesized in water and in the binary solvent (water + glycerin) via one-pot approach synthesis. The optical properties of the nanocrystals obtained with different synthesis parameters were characterized by UV-visible and photoluminescence spect

3. Variation of the milling conditions in the obtaining of nanocellulose from the paper sludge
ABSTRACT This work aimed to evaluate three different milling conditions, seeking the optimization of CNS isolation process. The paper sludge was chemically treated with detergent and H2O2, by two steps, to remove the noncellulosic contents (hemicellulose and lignin). After these treatments, the sample was milled with the variation of a liquid medium. The thr

4. Estudo da distribuição de luz vermelha e infravermelha em sangue humano diluído para circulação extracorpórea / Study of red and infrared light distribution in diluted blood for cardiopulmonary bupass surgery
Low level laser therapy (LLLT) is a treatment used in several applications, including the reduction of inflammatory processes. It could be used to prevent the systemic inflammatory response syndrome (SIRS), which some patients develop after cardiopulmonary bypass (CPB) surgery applied to solve some heart diseases. The objectives of this study were to set an

5. "Influência do Processamento Termomecânico sobre a Formação de Bandas de Cisalhamento e Propriedades Magnéticas de um Aço de Grão Não Orientado com 3%Si" / "Influência do Processamento Termomecânico sobre a Formação de Bandas de Cisalhamento e Propriedades Magnéticas de um Aço de Grão Não Orientado com 3%Si"
Non-oriented silicon steels are soft magnetic materials widely used in equipments for electricity generation and distribution. The obtaining of both high magnetic induction and low magnetic loss has been subject of research for the improvement and development of new nonoriented silicon steels. These works have focused on the development of alloys with lower

6. Interaction of hidrophilic porphyrins and extracellular hemoglobin with biomimetic models of biological membranes / Interação de porfirinas hidrofílicas e de hemoglobina extracelular com modelos biomiméticos de membrana biológica
In the first part of this work interactions of the cationic meso tetrakis (4-N-methilpyridil) porphyrin (TMPyP) and meso-tetrakis (4-sulfonatophenyl) porphyrin (TPPS4) in the free base forms with membrane model systems (ionic micelles, mixed micelles and phospholipids vesicles) in aqueous solutions, have been investigated by optical absorption, resonance lig

7. Efeitos nÃo lineares em lÃquidos orgÃnicos e meios nanoestruturados
In this thesis, we report studies of nonlinear transverse effects in organic liquids, carbon disulfide (CS2) and dimetil sulfoxide (DMSO), and of fluorescent emission effects in nanostructured media, more specifically, frequency upconversion in erbium doped barium titanate nanocrystals (BaTiO3:Er3+) and laserlike emission from inverted opal nanostructure of

8. Fluorescence photobleaching with spatial Fourier analysis: measurement of diffusion in light-scattering media.
A new method for the measurement of diffusion in thick samples is introduced, based upon the spatial Fourier analysis of Tsay and Jacobson (Biophys. J. 60: 360-368, 1991) for the video image analysis of fluorescence recovery after photobleaching (FRAP). In this approach, the diffusion coefficient is calculated from the decay of Fourier transform coefficients
