Specifically, the importance of the SBQ journals, such as the Quimica Nova (QN), Journal of the Brazilian Chemical Society (JBCS) and Revista Brasileira de Química (RVQ) as vehicles to disseminate the knowledge produced by the different graduate programs in chemistry is demonstrated. <![CDATA[SISTEMA NACIONAL DE PÓS-GRADUAÇÃO E A ÁREA DE QUÍMICA NA CAPES]]> The Coordination for the Improvement of High Education Personnel (CAPES), the Brazilian federal agency for graduate programs, plays a fundamental role for the expansion and consolidation of the National Postgraduate System (SNPG) and the execution of the National Graduate Plan (PNPG) 2011-2020. In this paper, we discuss the evolution of the Brazilian graduate program in chemistry and its role in the formation of highly qualified professionals in chemistry (academic master’s degree, professional master’s degree and doctoral degree) for the academy, teachers and lecturers for all levels of the education system, as well for the non-academic market. <![CDATA[DO BOLETIM INFORMATIVO ÀS REDES SOCIAIS: A EVOLUÇÃO NA COMUNICAÇÃO SBQ-ASSOCIADO]]> Boletim Informativo of SBQ has evolved over the last 35 years to reach more than 9.000 people such as students, teachers, and researchers around the country. This paper discusses its importance as a communication channel and its challenges to approach the public nowadays throughout the social media. <![CDATA[EVOLUÇÃO E INOVAÇÃO NO SETOR QUÍMICO BRASILEIRO: UMA VISÃO DOS ÚLTIMOS QUARENTA ANOS]]> The Brazilian chemical community shows positive characteristics that improved significantly during the past forty years: the scientific output is substantial, it contributes positively to the position of this country in the innovation rankings, the chemical companies create and export technologies and the larger share of post-graduates employed by the Brazilian industry works in chemical or chemistry-based companies. The chemical sector is thus an exception within the country, together with agrosciences. These facts are unexpected, considering that chemical companies do not occupy leading positions in the rankings based on patent filing and other innovation indicators, throughout the world. This article describes the context of Brazilian chemistry in the middle 1970s, the the well-designed government actions that mobilized academic researchers and industry professionals to build complex converging scenarios and a positive S&amp;T culture that is matched in few other areas, in this country. <![CDATA[A QUÍMICA AMBIENTAL NO BRASIL NOS 40 ANOS DA SBQ]]> This paper aims to present an overview of the ongoing of the Brazilian environmental chemistry over the last forty years inserted in the context of the Brazilian Chemical Society (SBQ). Initially, a brief history presents the main milestones and premise of its “birth” in the 1980s, as well as the set of major actions taken within the SBQ to consolidate and strengthen this area of research. Then, in a separated approach between atmosphere, hydrosphere and lithosphere, we present the evolution of the main topics covered in Environmental Chemistry in Brazil, as well as the contribution of the chemists in the interdisciplinary scenario that constitutes this area. Finally, an overview of the evolution of the teaching of Environmental Chemistry in Brazil is presented. <![CDATA[QUÍMICA ANALÍTICA NO BRASIL: ATUALIDADES, TENDÊNCIAS E DESAFIOS]]> This work describes the development of Analytical Chemistry in Brazil from the Brazilian Chemical Society (SBQ) foundation to the present days. Important historical facts were highlighted and data on the human resources formation, financial investments and scientific production were used to evaluate and contextualize the progress achieved. The evolution of the scientific events of the area was also presented. The survey shows that Analytical Chemistry has advanced a lot in these 40 years, occupying a prominent position in the international scenario. This growth is mainly due to the formation of qualified human resources, the organization of scientific societies and inductive policies. It was also verified that the quantitative advance was greater than the qualitative one. Thus, one of the challenges for the next years is to work at the knowledge frontier and increases the quality and impact of scientific production in Analytical Chemistry. The evolution of the area into current trends such as Nanoscience, Microfluidic, Omics, Chemometric, Green Chemistry and Chemical Speciation is also presented and discussed. <![CDATA[UM PANORAMA DA CATÁLISE NO BRASIL NOS ÚLTIMOS 40 ANOS]]> In this work, the catalysis area in Brazil is analyzed from several perspectives between 1977 and 2017.

An overview of the industry situation related to the area, as well as the evolution of scientific production in Brazil, are also discussed. <![CDATA[O ENSINO DE QUÍMICA E OS 40 ANOS DA SBQ: O DESAFIO DO CRESCIMENTO E OS NOVOS HORIZONTES]]> In this work, we aim to draw a panorama of the chemistry teaching area and its relation with the teaching division in SBQ 40 years. We start from the analysis of the Chemistry Teaching National Meetings in the last 15 years in comparison with those occurred in the 80’s and 90’s. Then, we present the growth of the chemistry teaching regional meetings and their capacity to congregate researchers and students in a decentralized way, important to the inclusion of new chemical educators. We discuss the scientific journals in the area considering the research on various themes. Finally, we analyze the growth of chemistry degree courses in Brazil and the number of researchers in the area, as well as the main themes explored by the research field of Chemistry Teaching in Brazil. <![CDATA[PANORAMA DA ELETROQUÍMICA E ELETROANALÍTICA NO BRASIL]]> Electrochemistry and Electroanalytical chemistry play an important role to face the challenges of the contemporary world. They have contributed to the advance of the scientific development of our country, helped to promote economic and social progress as well as cultural dissemination. These areas have greatly contributed to the knowledge about thermodynamics and kinetics of the electron transfer reactions, energy conversion, synthesis and modification of compounds, corrosion, and development of fast, sensitive, and selective analytical methods. This work presents an overview of the areas by analyzing the technical and scientific papers produced in Brazil on these subjects, and the analysis of the Brazilian scientific societies that were formed and consolidated, which have contributed to spread the scientific knowledge. The improvement of these areas can be attributed to the good quality of the human resources formed during long time as well as the growing of distribution of research groups in different regions of the country. The success/future of these areas are associated with good academic/scientific education, low cost of instrumentation, formation of networks of excellence between researchers, and large cooperation projects that improved with the sharing of ideas, technologies, infrastructure, and equipment. All of which has contributed to strengthening consolidated and emerging graduation programs. <![CDATA[A DIVISÃO DE FÍSICO QUÍMICA E OS 40 ANOS DA SBQ]]> One of the goals of this manuscript is to celebrate the forty years of the SBQ (Sociedade Brasileira de Química). We believe using historical analysis could benefit our researchers to overcome the challenges ahead, look into the future, to the scientific progress and the way science increases its problem-solving ability. There are several topics covered by the challenges in Physical Chemistry: nanoscience and nanotechnology, single molecule studies, gas phase photochemistry and photophysics, molecular structure, spectroscopy, reaction dynamics, interfacial phenomena, energy, and so on. However, the critical challenge for our Division still is to create a desired link between experimental approaches and theoretical knowledge. <![CDATA[A FOTOQUÍMICA BÁSICA E APLICADA NO BRASIL DURANTE OS ÚLTIMOS 40 ANOS]]> This paper describes the activities in the area of Photochemistry in Brazil, from its origins at the beginning of the last Century until now.
