For Gender Equality in Science

"All spiritual perfection is a real benefit:
Well then, science is spiritual perfection:
So science is a real benefit. '

(Princess Isabel file, Grão Pará Archive)1

Promoting the inclusion of women and girls implies to create opportunities for intellectual growth and to fight inequalities in access to skills, health, education, protection, profession, and well-being. In this context, it is stimulating to follow the promising worldwide progress towards the implementation of the 2030 United Nations' Agenda for Sustainable Development, which includes the achievement of gender equality and empowerment of all women and girls as a goal. The commitment of world leaders to this Agenda has given rise to several cheering initiatives, although there is still a long way to go before we genuinely approach sustainable development through the necessary combination of economic growth, social inclusion, and environmental protection.

To add to these efforts and mark the 30th anniversary of its first launching in 1990, the Journal of the Brazilian Chemical Society now publishes a special volume to honor the work of distinguished Brazilian Women in Chemistry. It contains original contributions in all aspects of Chemistry within the scope of the JBCS, submitted by women research leaders who illustrate and represent the quality of the current Brazilian chemical science. Given the enthusiastic welcome given by the community to this idea, reflected in the high number of submissions received for this special volume, the original proposal to release it in just one issue has been expanded to three. As part of this successful initiative of the Brazilian Chemical Society, the Editorial Board of the JBCS thanks all authors for considering our invitation and joining us on this special anniversary celebration.
