1. SYNTHESIS, ELECTRONIC AND SPECTRAL PROPERTIES OF NEW 1,3,4-THIADIAZOLE COMPOUNDS AND THE SPECTRAL ANALYSIS OF THEIR CONFORMERS USING DENSITY FUNCTIONAL THEORY
In this study, new 1,3,4-thiadiazole compounds were synthesised and characterised by FT-IR, 1H-NMR, UV-vis spectroscopy and elemental analysis, Furthermore, the relationship between the electronic and spectral data of the 16 conformers of each compound was investigated by theoretical calculations; the theoretical data were compared with the experimental resu

2. Physiochemical and Optical Properties of GdF3:Pr@LaF3@SiO2 Microspheres
The polyol-based co-precipitation process was employed for synthesis of GdF3:Pr (core) and GdF3:Pr@LaF3 (core-shell) microspheres (MSs). Subsequently, an amorphous silica layer was deposited surrounding the core-shell MSs, which was verified from high-resolution transmission electron microscopy (TEM), energy dispersive X-ray analysis (EDX) and FTIR results.

3. ESCALA TEMPORAL DA TURBULÊNCIA PARA ESCOAMENTO NOTURNO ACIMA DA COPA DE UMA FLORESTA TROPICAL ÚMIDA NA AMAZÔNIA / ON THE TURBULENCE TEMPORAL SCALE FOR NOCTURNAL FLOW ABOVE A TROPICAL RAINFOREST IN AMAZONIA
Desde 1998 o projeto LBA (Large Scale Biosphere-Atmosphere in Amazônia) vem monitorando continuamente os fluxos de energia, água e carbono na Amazônia utilizando o sistema de Covariância dos Vórtices (CV). Os resultados obtidos até agora apresentam um alto grau de incerteza, especialmente no que diz respeito ao papel do ecossistema amazônico no ciclo
