The Changing Nature of Multilateralism and Brazilian Foreign Policy

An important characteristic of the current international setting is the crisis of the structure in existence, rather than the emergence of a new order. The rise of new interests and demands, as well as the speed of the transformation make the current understanding of global governance more complex. Brazil, like other medium powers, has an interest in institutionalised multilateralism as a means of increasing its bargaining capacity and hindering the unilateralism of major powers, without being antagonistic to them. It is attempting to increase its weight in traditional international bodies, which provide the grounding for international legitimacy, as well as in new informal arrangements. While this strategy could lead to the establishment of a new hierarchy that brings in countries of growing relative importance, it has put the weight of regional integration into another perspective in Brazilian foreign policy.

Dielectric response of tungsten modified Ba(Ti0.90Zr0.10)O3 ceramics obtained by mixed oxide method

The electrical response of Ba(Ti0.90Zr0.10)O3 (BZT) ceramics obtained by the mixed oxide method as a functionof tungsten content was investigated. According to X-ray diffraction analysis the single phase BZT1W (1wt.% W doped BZT) and BZT2W (2 wt.% W doped BZT) ceramics, crystallized in a perovskite structure, wereobtained. It is also shown that tungsten substituted ceramics can be sintered at a reduced temperature whencompared to the undoped BZT. Electron paramagnetic resonance (EPR) analyses reveals that substitution ofTi4+ by W6+ causes distortion in the crystal structure changing lattice parameter. Substitution of W6+ on B-siteof ABO3 perovskite BZT ceramics shifted the phase transition to lower temperatures up to a tungsten contentof 2 wt.% leading to a relaxor-like behaviour.Keywords: donor dopant; ceramics; dielectric response; mixed oxide method
