Contribuição à organização da pesquisa em Química e os desafios da interação com outras áreas do conhecimento

This article provides some aspects that allow making a current reading of the situation of the Brazilian Chemistry that permit us considerate it as a strategic area. They are still presented some initial proposals related to the organization of the research as well as to win the challenges of the relationship with the other areas of the knowledge.

Interfaces e organização da pesquisa no Brasil: da Química à Nanotecnologia

Nanotechnology can be viewed as a powerful tool, capable of shaping the chemistry of atoms and molecules, converting them into exciting nanosized and nanostructured materials, devices and machines. However, in pursuing this task, an exceptional ability is required to deal with complex inter- and multidisciplinary approaches, as imposed by the nanoscale. A new research organization framework, capable of promoting cooperative interactions in many complementary areas, including the industries, is demanded. In this sense, an interesting example are the nanotechnology networks and millenium institutes recently created in Brazil. The highlights and weakness of such cooperative research networks are discussed, in addition to relevant nanotechnology themes focusing on the special needs and resources from the developing nations.

Organização de pesquisa no Brasil: lições do passado, propostas para o futuro

Chemical research in Brazil has grown significantly in the past 20 years, largely thanks to the Brazilian S&T Development Program of the federal government (PADCT). However, the newly achieved levels of highly qualified manpower and research infra-structure require new research organization frameworks to make science, technology and innovation really useful and meaningful for the citizens. The current requirements for creating viable networks of academic and industry researchers are presented and discussed as well as some structural and procedural bottlenecks that have to be eliminated, to achieve maximum high-quality science, technology and relevant innovation output.

Aspectos e fatores da produtividade em pesquisa, desenvolvimento e inovação

Comparison of national budgets for R&D is often made but it should consider the relative productivity and their factors. In Brazil, inefficiency factors as well as their causes have been diagnosed since the late 60's and solutions have been proposed within various governmental organisms, from CNPq to the strategy think tanks. Problems that hinder R&D and innovation in Brazil are reviewed from a historical perspective together with the proposed solutions providing a detailed analysis of the difficulties that have to be overcome to achieve a more effective innovation environment, adequate for the present times, challenges and opportunities.

A indústria de processamento químico no Brasil: suas motivações para pesquisa e desenvolvimento e suas interfaces com as políticas governamentais

As the Chemical Science is an experimental one a Chemical Industry require technical people in all its staff level: from Directors and Managers to Operators. This chemical and chemical engineering based education is the foundation of the innovate process and motivation. The paper discusses this and the role of Public Policies to improve the R&D and innovation in the Brazilian Chemical Industry.

Biologia química: uma estratégia moderna para a pesquisa em produtos naturais

This paper presents an overview of the Natural Products Research in Brazil in the last five years (2002-2006), and also discusses how some relevant aspects of the Chemical Biology area could create new research opportunities and challenges for the natural product chemists. In addition, some aspects of the scientific policies and their impact on current projects are discussed.

HIV - recentes avanços na pesquisa de fármacos

The development of new antiretroviral drugs is a dynamic process that is continuously fueled by identification of new molecular targets and new compounds for know targets. The current available drugs can be classified into five categories: nucleoside analogues reverse transcriptase inhibitors, non-nucleoside reverse transcriptase inhibitors, protease inhibitors, integrase inhibitors and entry inhibitors (fusion inhibitors and CCR5 antagonist). In addition, the maturation inhibitors may be considered as potential target for chemotherapeutic intervention. This review presents some anti-HIV agents that have already gone through the advance development process for final approval for the treatment of AIDS.

Fotoprotetores derivados de produtos naturais: perspectivas de mercado e interações entre o setor produtivo e centros de pesquisa

Ultraviolet radiation is the major exogenous mediators of skin damage. To prevent such damage, sunscreen products are used. New research aims at both the elucidation of new sunscreen compounds, as well as new assets for supporting and synergistic action. In this article it is presented a systematic data of innovation for sunscreen and a discussion on prospects for partnership between universities and enterprises, where it is believed that the innovations in cosmetics, driven by the constant demand of the market in new products, may be a stimulus for the interactions between university and company in Brazil.

Produtividade em pesquisa do CNPq: análise do perfil dos pesquisadores da Química

The profile of the CNPq Research Productivity Program in Chemistry was studied using the Plataforma Lattes curricula of all researchers with grants in effect as of March 2009. Most of them are male (67.2%), working in Federal Universities (59.4%) and located in Southeastern Brazil (63.7%). There is no evident homogeneity among researchers of the same level/category concerning the productivity criterions used (the H index and the scientific productivity of the last five years). CNPq and the Chemistry Assessor Committee have been focusing on making their judgments unbiased, by using quantitative parameters, but such overlap is still noticeable.

A problematização das atividades experimentais na educação superior em química: uma pesquisa com produções textuais docentes

Through the analysis of articles with proposals for experimental activities and with current pedagogical, epistemological and environmental discussion on experimentation by Chemistry professors, this paper investigates ways of highlighting relevant methodological characteristics that can be incorporated in experiments. Based on analysis of the suggestions for experiments it appears that of particular importance are: a concern for students' physical welfare and for the effects of residues; the need to confront an impoverished infrastructure that hinders experimentation; and the valorisation of clarifying student knowledge. It argues in favour of the need to set out the problems of experimentation in educators' professional development.
