| Welcome to JBCS |
"Brazil is the 15th in scientific production, having
surpassed many countries with a greater tradition in
research and human resource formation", has been recently
stated by Mr. Jorge Guimarães, the Brazilian Federal
Agency for Support and evaluation of Graduate education
(CAPES) President.
There is no doubt many graduate programs have
equaled the most important international research centers
in their excellence levels. The same happens in the
Chemistry field. The excellence of some graduate programs
is internationally recognized. If graduate schools are
doing well, the same can not be said about the chemistry
undergraduate level, though. The demand for chemistry
courses is low and our great challenge is to show young
students that the chemical career is financially and
professionally worthwhile. Changing this situation should
be on the Brazilian Chemical Society (SBQ) agenda.
