Editorial - The dream is still alive...
We are highly pleased to publish issue # 1 of the 20th
volume of the Journal of the Brazilian Chemical Society, JBCS.
We are celebrating twenty continuous years of a scientific
journal published in English in Brazil. That 1987 dream, when
the planning for the journal started, came to be a challenge in
1990, with the releasing of the first JBCS issue. The scenario
and expectations of that time are reflected in two parts of the
first JBCS editorial, written by Professor Eduardo Motta Alves
Peixoto, its founder and first Editor:
"In Brazil, as in many other countries, it has been immensely
difficult to establish a balance between national development
and the investment in chemistry. It is still commonly thought
that economic growth necessarily and justifiably entails the
sacrifice of basic research. A change of mentality is required,
with the more active and purposeful participation of industries,
government and the scientific community, so that by the year
2000 scientific research may be managed realistically and
effectively..."
"...Our mission and our commitment are to the present and
future generations, safeguarding the prosperity and welfare of
the world with the best in the chemical research. Not just a new
international journal."
