A Catálise no Brasil nos últimos 25 anos: uma história de sucesso

In the last 25 years the research in catalysis has passed from heterogeneous processes mainly applied to petrochemical industries to homogeneous processes applied to fine chemicals and green chemistry. In this context the Brazilian Chemical Society (SBQ) is playing an important role in the organization of this interdisciplinary area involving researches from different fields of physical sciences.

A história, evolução e crescimento da Eletroquímica: Eletroanalítica nestes últimos 25 anos

This text describes the development of Electrochemistry and Electroanalytical Chemistry in Brazil from the pioneers at the IQ/USP in the 70's to the present day status. It explains how the members of the scientific community organized themselves before the establishment in 1993 of a specific division within the Brazilian Chemical Society (SBQ) through bi-ennial meetings (Brazilian Symposium of Electrochemistry and Electroanalytical Chemistry - SIBEE). Those SIBEE meetings, in a present number of 12, are described individually giving some emphasis on their organizers, the invited speakers and the statistics and overall structure of the event. The activities of the Electrochemistry and Electroanalytical Chemistry Division of the SBQ from 1993 are also briefly discussed as well as some considerations are made on the present and future of these fields.

SBQ-25 anos: Físico;Química

The authors present a concise but critical review on the development of physical chemistry in Brazil, as seen by two experimental scientists with more then 25 years of experience in the Brazilian academics.

Química Medicinal: 25 anos de planejamento racional de fármacos

The Sociedade Brasileira de Química is commemorating its 25th anniversary, and this paper is intended to draw an overview of the Brazilian Medicinal Chemistry over all these years. In 1977 Brazil had almost no activities at all in the field, albeit many efforts were already on the way for encouraging Brazilian Scientists to enter the area. Among many different endeavours to help medicinal chemists to fulfil their proposals and the establishment of an on-going research with the help of networks, the Sociedade Brasileira de Química created, in 1991, its own Division on Structure and Activity Relationship, which became the Division of Medicinal Chemistry, in 1997.

Química analítica brasileira durante os 25 anos da SBQ: contexto atual e senso comum

This work presents an overview of the development of analytical chemistry in Brazil in the last 25 years under the influence of Brazilian Chemical Society (SBQ). It is shown that the common sense that analytical chemistry is still an under-developed area is not true. Data from specialized literature show a significant contribution of Brazilian analytical chemists in high impact periodicals and for several areas there is a good adherence among works carried out in Brazil and abroad according to a comparison of studies presented in the 11th Brazilian Meeting on Analytical Chemistry (Campinas, September, 2001) and the XI European Conference on Analytical Chemistry (Lisboa, September, 2000). According to the opinion of investigators in this area, there are some topics that require a focused attention for proper evolution. However, there is an absolute consensus about the evolution of graduate programs and the need to improve and extend strategies to absorb newcomers in the area. Some suggestions are presented considering possible pathways of analytical chemistry in Brazil.

Química de materiais em 25 anos de SBQ

Communications on Chemistry of Materials topics were already presented in the first annual meetings of the Brazilian Chemical Society, dispersed throughout various meeting sections. The SBQ Materials Chemistry division was organized in 1993, attracting those members with an interest in the composition, structure and properties of materials, as related to their functions. This paper is an account of the development of Materials Chemistry research in Brazil, based on the SBQ annual meetings data.

25 anos de quimiometria no Brasil

Chemometric activities in Brazil are described according to three phases: before the existence of microcomputers in the 1970s, through the initial stages of microcomputer use in the 1980s and during the years of extensive microcomputer applications of the ´90s and into this century. Pioneering activities in both the university and industry are emphasized. Active research areas in chemometrics are cited including experimental design, pattern recognition and classification, curve resolution for complex systems and multivariate calibration. New trends in chemometrics, especially higher order methods for treating data, are emphasized.

La Sociedad de Beneficencia de Señoras del Rosario: 160 años en manos de mujeres rosarinas (25 de junio de 1854-25 de junio 2014)

Las Señoras del Rosario inauguraron su Sociedad de Beneficencia el 25 de junio de 1854. El objetivo de las mujeres rosarinas fue garantizar la supervivencia de los enfermos y de las enfermas de la sociedad civil, y por ello decidieron crear un hospital en la zona más alejada del núcleo urbano, que hoy corresponde a la zona macrocéntrica de la ciudad. Esta Sociedad fue la primera de la República Argentina que se dedicó a la atención de la salud, y por ello en octubre del año siguiente las socias decidieron fundar el primer Hospital de Caridad de la ciudad destinado a los habitantes carentes de recursos y no militares de profesión.

A 25 años de los saqueos. Una expresión del conflicto: Dibujos de niños y niñas de 8 y 9 años.

En este artículo se analiza uno de los casos más conocidos y recordados de la historia contemporánea de la ciudad de Rosario de la República Argentina: la reacción de la sociedad civil ante la terrible crisis económica producida en el país en el año 1989, que condujo a la caída del gobierno democrático del radical Raúl Alfonsín, es decir, la primera presidencia democrática que había sido recuperada después de la última dictadura militar de los años 1976 a 1983. El trabajo recupera los dibujos que llevaron adelante los niños y niñas de 8 o 9 años, los cuales participaron en el saqueo de supermercados durante los últimos días del mes de mayo de 1989.
