1. Synthesis and characterization of Rare Earth compounds with potencial appplication in ionizing radiation detection / Síntese e caracterização de compostos de terras raras com potencial aplicação na detecção de radiação ionizante
Rare Earth (RE) inorganic phosphors play an important role as ionizing radiation detectors when applied to medical imaging techniques like radiology and tomography. These phosphors is to convert the high energy radiation absorbed photons (X or ?-rays) into visible photons, leading to better quality images and reducing the time the patient is exposed to radia

2. Determinação indireta de N-acetil-L-cisteína por injeção em fluxo empregando Ce(IV) e ferroína
An indirect flow injection spectrophotometric procedure is proposed for the determination of N-acetyl-L-cysteine in pharmaceutical formulations. In this system, ferroin ([Fe(II)-(fen)2]2+) in excess, with a strong absorption at 500 nm, is oxidized by cerium(IV) yielding cerium(III) and [Fe(III)-(fen)2]3+ (colorless), thus producing a baseline. When N-acetyl-
