Why to publish a special issue for young researchers?

This special issue is dedicated to young researchers/ professors developing their activities in chemistry, either in Brazilian Universities or Research Institutes. The idea was born among the editors of the JBCS as a way to publicize research activities run by young researchers that had been incorporated into the national research system in the last 10 years.
