As of today, the Directory of Open Access Journals lists 58 titles under Chemistry.
The list of titles might be of interest to Chemists Without Borders members, as the journals are published in many countries - including Japan, China, Korea, Slovenia, Croatia, Thailand, Turkey, India, the USA, to name a few.
One way any Chemist can easily advance the cause of Chemists Without Borders is to make a point of reading or browsing through journals from developing countries. Cite a fellow researcher in a developing country - or invite them to participate in a research project.
To advance the cause of Chemists Without Borders' Chemistry Education, have students do at least one assignment using a resource such as the DOAJ list, and specify that students include the works of authors from developing countries.
