Announcements

MDPI has just become the first open access (OA) publisher to reach the milestone of one million articles published. That is one million articles freely available to all, to circulate and build upon! We are proud to share this special moment with the global scientific community.

This landmark has been reached thanks to the immeasurable support of more than 600,000 expert reviewers, 66,000 editorial board members and 6700 hard-working colleagues across MDPI’s global offices.

Within more than 25 years of publishing, our journals received 2.1 million manuscripts and generated 4.6 million peer review reports to get to one million papers published.

Reaching the milestone of one million articles published reinforces our mission to remove any existing barriers and to make scientific research accessible to all. Since its inception, MDPI’s goal has been to create reliable processes to make science open. This is a path towards facilitating the dissemination of novel insights in scientific communities.

Regular feedback from authors and reviewers shows that our service is greatly appreciated and needed. At the same time, the feedback helps us identify areas for further improvement.

As it stands, a significant share of published research findings remain closed access. More than half of the content published with the most well-known legacy publishers stays behind a paywall, and that is not including articles published in hybrid OA journals, or made available months or years after publication.

A new policy announced by the US administration in August 2022 requires that, as of January 2026, all US federally funded research be made freely and immediately available after publication. While the new policy does not mandate articles be published under an open access license, it is aligned with the open access movement in removing all barriers to research. Similarly, some of the most advanced research institutions in the world intend to have all funded research articles published in open access by 2025.

MDPI is proud to be the leading agent of the transition to open access.

"Thanks a Million" to all the contributors!

We are currently recruiting Editorial Board Members (EBMs) for MDPI journals indexed in the Emerging Sources Citation Index (ESCI) in Web of Science. In particular, we are looking for experts who are interested in aiding in the development of our journals and safeguarding the scientific quality of the published findings.

Journals currently listed in the ESCI will receive an Impact Factor in June 2023, according to the changes announced by Web of Science (Clarivate). Therefore, this is an excellent time to become an Editorial Board Member for one of these fast-developing journals.

If you are interested in sharing your expertise in one of the journals listed below, please send us an application using this link.

The Editorial Office of the journal will contact you once the application has been approved.
Editorial Board Members are responsible for academic decisions on manuscripts in their field of expertise, will edit Special Issues, and may be invited to review manuscripts. The initial term lasts for two years, after which it can be renewed, and entails the following:

• Prescreening and making decisions on new submissions related to your research interests;
• Setting up at least one Special Issue during your term on a topic related to your research interests (or supervising Special Issues related to your research field);
• Providing input or feedback regarding journal policies;
• Helping to promote the journal among your peers or at conferences;
• Attending Board meetings to suggest journal development strategies;
• Reviewing manuscripts.

Editorial Board Members are entitled to a full waiver on one publication per year in the journal that they serve and need to be experts in their fields.

The list of ESCI journals can be found here: https://www.mdpi.com/about/journals/esci.

Please find the list of ESCI journals, categorized by subject, for which we are recruiting Editorial Board Members below.

We are pleased to announce that the website of the MDPI Sustainability Foundation has been revamped! For the past couple of months, our UX UI team and front-end developers have been working hard to launch the website in time for the opening of the Sustainability Awards nominations.

The website is not the only thing that has had a remodeling. Indeed, the format of the Emerging Sustainability Leader Award (ESLA) has been updated. ESLA is now a competition open to individual researchers or start-ups founded by researchers under the age of 35. Nominee applications will go through 2 rounds of selection until the final 3 are decided. The finalists will then be invited to give pitch presentations during the Award Ceremony to win either first place (10,000 USD) or runner-up (2 x 5000 USD).

The World Sustainability Award, on the other hand, remains the same: a total prize money of 100,000 USD is up for grabs by senior individual researchers or groups of researchers from the international research community.

Nominations for both the World Sustainability Award and the Emerging Sustainability Leader award are now open! Check out our new website for more information on how to nominate.

Peer Review Week began 19 September 2022 under the theme of “Research Integrity: Creating and Supporting Trust in Research”. Through various blog articles, podcast, and webinar, we discussed this crucial subject throughout the week, celebrating the essential role peer review plays in maintaining research quality.

To begin, we held a Webinar on the topic. Professor Peter W. Choate and Dr. Emmanuel Obeng-Gyasi joined Dr. Ioana Craciun, one of MDPI’s scientific officers, for an in-depth discussion.

We invite you to view the event recording:

During the week, the MDPI Blog in a series articles highlighted how good Peer Review safeguards research integrity. The following topics were covered:

• Peer Review Week 2022
• Research Integrity
• What We’ve Learned About Peer Review Reports
• 4 Steps to the Perfect Peer Review Report
• How to Write the Perfect Peer Review Report: An Interview
• Inviting Great Peer Reviewers

In a new edition of Insight Faster, an MDPI podcast, we were delighted to talk to the co-chairs of the Peer Review Week committee, Jayashree Rajagopalan (Senior Manager of Global Community Engagement for CACTUS) and Danielle Padula (Head of Marketing and Community Development at Scholastica) to get their take on this year’s event and its related topics.

You can find the Podcast here.

We hope you enjoy the contents!

In order to acknowledge our reviewers, who so generously dedicate their time to reviewing papers and demonstrate diligence, professionalism, and timeliness when reviewing manuscripts, MDPI journals regularly offer outstanding reviewer awards to scholars who participate in the peer-review process.

We are proud to recognize this year’s winners in the “Physical Sciences” category for their outstanding contributions among extensive competition by presenting them with an Outstanding Reviewer Award.

We would like to take this opportunity to congratulate all of the winners on their achievement. MDPI will continue to provide support and recognition to the academic community.

The winners mentioned below were carefully selected by the journal editors based on an outline of their research and the work to be presented at an academic conference.

We would like to warmly congratulate the winners of this year’s Travel Awards and wish them the greatest success with their future research endeavors. MDPI will continue to enhance communication among scientists.
