About MDPI and Its Journals

Multidisciplinary Digital Publishing Institute (MDPI) is a leading publisher of open-access scientific journals. Founded in 2010 by Shu-Kun Lin and Dietrich Rordorf, MDPI is headquartered in Basel, Switzerland. The organization has significantly expanded its reach, with editorial offices in 11 countries, including multiple offices in China, Romania, Serbia, the UK, Canada, Spain, Poland, Japan, Thailand, and Singapore[1].

Rapid Growth in Publications

Since its inception, MDPI has experienced remarkable growth. In 2019, the publisher released over 110,000 papers, a number that more than doubled in 2021 to 235,638. In 2020, MDPI became the largest publisher of open-access papers and the fifth-largest overall in terms of journal output[1].

Special Issues: A Key Feature

One notable aspect of MDPI's publishing strategy is the use of special issues. These are collections of papers focused on specific topics, often curated by guest editors rather than the journal's editorial board. This model has been instrumental in MDPI's success, with nearly 88% of its papers published in special issues. The number of special issues has skyrocketed, from 388 in 2013 to over 39,000 in 2021, with each journal hosting approximately 500 special issues on average[1].

Concerns Over Peer Review Efficiency

The proliferation of special issues has raised concerns about the effectiveness of peer review at such a large scale. With journals like International Journal of Molecular Sciences and Sustainability hosting numerous special issues daily, there are questions about the thematic relevance to the journals and how to maintain rigorous peer-review standards[1].

Ethical Standards and Publication Integrity

MDPI is committed to maintaining high ethical standards in publication. The organization is a member of the Committee on Publication Ethics (COPE) and adheres to strict guidelines to prevent plagiarism, data falsification, and other unethical practices. Editors are trained to handle such cases with a zero-tolerance policy, using tools like iThenticate to verify the originality of submitted content[3].

Scope and Aims of MDPI Journals

MDPI journals, such as Eng, cover a broad spectrum of engineering fields including electrical, electronic, and information engineering; chemical and materials engineering; energy engineering; mechanical and automotive engineering; industrial and manufacturing engineering; civil and structural engineering; aerospace engineering; biomedical engineering; geotechnical engineering and engineering geology; ocean and environmental engineering; and computational and mathematical engineering[3].

Impact on Scientific Community

MDPI's open-access model has significantly impacted the scientific community by making research accessible to a wider audience without the financial barriers of traditional subscription-based journals. This model aligns with the mission of encouraging scientists to publish their experimental and theoretical research in as much detail as possible, ensuring that results can be reproduced[3].
