Relações Públicas pela sustentabilidade: o profissional dentro das organizações

This research has the purpose of highlighting one of the acting areas of the public relations' professional, ensuring that he has enough competence to develop his work within an organization, implementing actions and programs in pursuit of a sustainable growth. The study starts with an analysis of the organizations and their communication process to further expand the understanding of the concept of sustainable development and finally addressing the role of public relations and the scenario organizational that it is envolved. In the globalized world we live in, our relationships are mediated by the capitalism: economic system that is concerned with the higher production seeking only profits. Thus, some organizations - acting in accordance with this model, end up don't caring about the environment around them, using it only like an instrument for achieving their goals. However, because this type of action, the contemporary society is facing serious environmental problems, fact that arouses the attention of civil society members and international organs, concerned to combine progress with sustainable development. The public relations' professional, concerned about the concretization of a concept and favorable institutional identities, besides the obvious envolvement with environment, can act in defense of this, implementing policies and campaigns ecologically correct for sustainability

The Aerosol OT + n-butanol + n-heptane + water system: Phase behavior, structure characterization, and application to Pt70Fe30 nanoparticle Synthesis

A phase diagram of the pseudo-ternary Aerosol OT (AOT) + n-butanol/n-heptane/water system, at a mass ratio of AOT/n-butanol = 2, is presented. Conductivity measurements showed that within the vast one-phase microemulsion region observed, the structural transition from water-in-oil to oil-in-water microemulsion occurs continuously without phase separation. This pseudo-ternary system was applied to the synthesis of carbon-supported Pt 70Fe30 nanoparticles, and it was found that nanoparticles prepared in microemulsions containing n-butanol have more Fe than those prepared in ternary microemulsions of AOT/n-heptane/water under similar conditions. It was verified that introducing n-butanol as a cosurfactant into the AOT/n-heptane/water system lead to complete reduction of the Fe ions that allowed obtaining alloyed PtFe nanoparticles with the desired composition, without the need of preparing functionalized surfactants and/or the use of inert atmosphere. © 2007 American Chemical Society.
