About Challenges


Challenges (ISSN 2078-1547) is a unique international scientific open access journal. It publishes scholarly content which is typically not publishable in traditional research journals, such as research proposals (funded and unfunded), research plans (e.g., a protocol for a systematic review, further research of a technology application, etc.), research or technology ideas, policy studies relating to science and scholarly research, open contests aiming at solving grand challenges, prize announcements, description of prototypes, calls for or description of international research collaborations or complementary support, etc.

Manuscripts submitted to Challenges must comply with the highest scientific standards and will be peer-reviewed before a decision regarding possible publication in the journal is made. For funded research proposals, the peer-review process will be skipped and manuscripts published after copy-editing and with comments from the grant review attached, if available. In addition, authors will benefit from discounts on possible publication charges if they subsequently submit papers related to the research project to other MDPI journals.

  • research proposals; research plans; research ideas
