1. Influência da intensidade de carregamento e utilização de placa oclusal plana em supraestruturas metálicas parafusadas sobre implantes: estudo fotoelástico / Influence of the intensity of loading and use of an occlusal splint flat screw-retained metal superstructures on implants: photoelastic study
Objetivo: Avaliar por meio do estudo fotoelástico qualitativo as tensões geradas no longo eixo dos implantes e interimplantes nas regiões cervical, média e apical quando submetidos a diferentes carregamentos com ou sem interposição de placa oclusal plana. Método: Foram confeccionados quatro modelos fotoelásticos, com dois implantes hexágono externo

2. Self-organizing super-structures formed from hydrogen-bonded biimidazolate metal complexes
Manipulation of molecular crystals formed from self-organization is one of the important methods to develop the new molecular functional materials. In particular, we look upon mutual cohesive interactions of hydrogen bonding and metal coordination as one useful tool to construct the preprogramming superstructures. In this study, five controlled superstructur

3. Self-recognition in helicate self-assembly: spontaneous formation of helical metal complexes from mixtures of ligands and metal ions.
On treatment with copper(I) ions, mixtures of the [oligo(2,2')-bipyridine] strands 2-5 yield spontaneously the double helicates 2H(2)-2H(5) without significant crossover. Similarly, when a mixture of the two tris-bypyridine ligands 1 and 3a (containing different substitutions) is allowed to react with copper(I) and nickel(II) ions, only the double helicate 2
