1. Síntese e estudo das propriedades ópticas e magnéticas de pontos quânticos de Pb1-xMnxS crescidos em matrizes vítreas
In this Thesis PbS and Pb1-xMnxS quantum dots (nanocrystals), hosted in glass matrix, were synthesized and characterized. Optical absorption (OA), Electron Paramagnetic Resonance (EPR) and Magnetization curves (SQUID) were used to characterize the as-prepared nanocrystals. Within the range of 0.41 eV (gap of bulk PbS) to 3.5 eV (gap of bulk MnS) the OA bands

2. Análises das propriedades ópticas, morfológicas e estruturais de pontos quânticos de PbS sintetizados a partir de diferentes concentrações de dopantes
PbS quantum dots has been grown in oxide glasses by two distinct methodologies according to the dopants, using the fusing method at 1200C. The host glass matrices used were SNAB (SiO2.Na2CO3.Al2O3.B2O3) and SNABP (SiO2.Na2CO3.Al2O3.B2O3.PbO2), with PbS bulk and S (sulphur) added as dopants, respectively. Thermal treatments were applied in a systematic way in

3. Evidence for a Cytoskeleton-Associated Binding Site Involved in Prolamine mRNA Localization to the Protein Bodies in Rice Endosperm Tissue1
Previous studies have demonstrated that the mRNAs encoding the prolamine and glutelin storage proteins are localized to morphologically distinct membranes of the endoplasmic reticulum (ER) complex in developing rice (Oryza sativa L.) endosperm cells. To gain insight about this mRNA localization process, we investigated the association of prolamine poly
