Global energy demand is still increasing based on consumption of fossil fuels, and its consequences such as greenhouse gases emissions (for instance CO 2 emissions) are concerns for humanity due to the global warming. In the context, climate changes issues are clearly one of the big issues for our future. Thus, measures for mitigating its effects are treated, discussed, and analyzed to help us to reduce those problems. In this regards, Carbon Capture and Storage (CCS) technology may represent a strategic alternative for CO 2 abatement. Using bibliographic review methodology; including law analysis as well as the development of a logical explanation approach and deductive reasoning, in this paper, we analyzed the climate change mitigation strategy of CCS, and the perspectives of implementing this technology in Brazil, as well as we discussed the Civil Liability regarding CCS, focusing on the Brazilian environmental law. Our results show that the lack of a legal and regulatory framework of CCS activities represents the main barrier to its national development.

Visando agregar ao ensino de química conceitos e habilidades em nanotecnologia, alunos do ensino médio prepararam nanopartículas superparamagnéticas em um projeto de ensino supervisionado no laboratório do Instituto de Química da USP. Foi empregado um método experimental didático, que utiliza reagentes e vidrarias que podem ser encontrados na maioria das escolas públicas e privadas. As aplicações das nanopartículas foram exploradas didaticamente, simulando a concentração e remoção de manchas de óleo na água. nanopartículas magnéticas, preparação de nanopartículas, experimento didático, remediação ambiental
