We are pleased to announce the launch of a new initiative—the MDPI Special Issue Mentor Program.

This program will enable early career researchers (who must hold a Ph.D. in a related field) to experience editing a Special Issue in MDPI journals, under the mentorship of our experienced Editorial Board Members or other experienced scientists. The mentor program will provide an excellent opportunity for early career scientists to gain editorial experience, and to cultivate their ability to edit scientific research.

The mentee’s responsibilities include:

• Proposing a Special Issue title and assisting the mentor in preparing a summary (around 200–400 words) and 3–10 keywords describing the background, importance, and goal of the Issue;
• Writing a brief promotion plan for the Special Issue;
• Preparing a list of scholars who may be interested in the Issue and personally e-mailing invitations on behalf of Guest Editors;
• Writing an editorial for the online Special Issue together with the mentor.

The mentor’s responsibilities include:

• Conducting a final check before the Special Issue is published online;
• Performing editorial control of the Special Issue and quality control of the publications, both of which must be carried out in a timely manner;
• Providing suggestions to younger scholars if they have any doubts or concerns regarding submissions;
• Organizing video calls with young scholars and the Editorial Office regularly to discuss problems and improvement suggestions for the Special Issue;
• Making and submitting decisions regarding submissions with the assistance of mentees.

Certificates and awards:
After the Special Issue closes, the Editorial Office will provide official certificates for all the mentors and early career researchers.

If you are interested in this opportunity, please send your Special Issue proposal to the Editorial Office of a journal you choose, and we will discuss the process (i.e., mentor collaboration, Special Issue topic feasibility analysis, etc.) in further detail. The full list of MDPI journals is as follows: https://www.mdpi.com/about/journals.

In addition to the new Special Issue Mentor Program, we will continue to welcome all Special Issue proposals focusing on hot research topics.

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 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.

Catalysts (ISSN: 2073-4344) has launched the Section “Computational Catalysis”, which is dedicated to publishing original computational-based investigations within the broad field of catalysis.

Founded in 1996, MDPI was one of the first fully Open Access publisher. Over 25 years MDPI has grown to become the largest Open Access publisher globally, publishing over 160,000 articles across more than 350 journals in 2020. At the core, MDPI was founded in response to a pressing need of fast publication and inclusion. The scholar was set at the centre of the publication process for the first time. Acting as a service provider, rather than a product provider, MDPI exists to help scientists achive their objective to disseminate research results. At MDPI, we believe scientists deserve a better service from the publishing world.

The International Open Access Week (Open Access Week), founded by the SPARC (the Scholarly Publishing and Academic Resources Coalition) Alliance and student partners in 2008, has been successfully running for 13 years. As an advocate and pioneer of open access publishing, MDPI actively responds to the call of International Open Access Week. This year’s theme of “It Matters How We Open Knowledge: Building Structural Equity” highlights the Recommendation’s call for equitable participation from all authors and readers.

For the last 25 years, MDPI has been committed to disseminating open research. Here is a video showing MDPI’s Commitment to Equity, Inclusion and Diversity for More than 25 Years.

International Open Access Week is an important opportunity to catalyze new conversations, create connections across and between communities that can facilitate this co-design, and advance progress in the building of more equitable foundations for opening knowledge—discussions and actions that need to be continued, year in and year out. MDPI has always aimed to provide professional and efficient publishing services to scholars around the world.

Our mission is to make scientific research accessible to everyone; this year, we interview and hold discussions with open science ambassadors on how to build an equal and inclusive environment for open science. Academic editors help us collaborate with more institutions to advocate for open access ideas.

Besides this, our scientific community is a key driver of our success and MDPI’s remarkable growth. Despite the pandemic, we have prepared online conferences and workshops to gather scholars from different communities.

The Basel Sustainable Publishing online forum provides an equal opportunity for stakeholders and researchers from multi-cultural environments to exchange ideas and eliminate barriers to participation.

Conference date: 25 October 2021, online
Conference website: https://bspf2021.sciforum.net/
Main topics: MDPI discusses the current dilemma of open access science from various perspectives such as governments, libraries, and publishers, and related measures on how to change the status quo of discrimination from a global perspective.

We aim to support equality, inclusion, diversity, and accessibility in scholarly communications. We collaborate with universities and key laboratories and have scholarly communications with researchers, teachers, and students on open access workshops.

MDPI is committed to providing open access and high-quality publishing services for scholars and promoting rapid dissemination of academic achievements. We hope to promote the practices and policies of open access publishing and diversify the dissemination of academic achievements.

Rigorous peer-review is the cornerstone of high-quality academic publishing. Over 369,916 scholars served as reviewers for MDPI journals in 2020. We are extremely appreciative of all those who made a contribution to the editorial process in this capacity. At the beginning of every year, journal editorial offices publish a list of all reviewers’ names to express our gratitude. In addition, this year, the MDPI Top Reviewer Award was announced, to recognize the very best reviewers for their expertise and dedication, and their high-quality, and timely review reports. We are pleased to announce the following winners of the 2020 MDPI Top Reviewer Award:

UN's 17 Sustainable Development Goals (SDGs) are the blueprint to achieve a better and more sustainable future for all. In 2020 the SDG Publishers Compact was launched, aimed to inspire publishers and accelerate progress to achieve the 17 goals by 2030. Members of the programme are committed to support the publication of materials that will promote and inspire actions towards SDGs.

MDPI is an eager advocate of SDGs and has already been supporting the programme by creating Special Issues and publishing a series of books on SDGs prior to joining the Compact in 2021. MDPI's Sustainability Foundation initiated the World Sustainability Awards in 2016. We fully support UN's goals to promote sustainable actions that make the world a better place for all and, as part of its commitment, we will focus our actions on SDG10: Reduced Inequalities whilst promoting all 17 SDGs. For more details, please visit the programme’s website: https://www.un.org/sustainabledevelopment/sdg-publishers-compact/.

Joining this initiative was a unanimous decision. MDPI has in its core values the dissemination of science for all, breaking the wall between research access and under-represented members of the scientific community and the general population. To support this initiative further and continue to support under-represented scientists, MDPI will take a series of actions that will be announced once ready.

The first action MDPI takes is to nominate Dr. Liliane Auwerter as the coordinator of the programme. Dr. Auwerter studied Environmental Process Technology (UTFPR, Brazil), obtained her MSc degree in Water and Environmental Engineering (University of Surrey, UK) and in 2020 completed her PhD in self-healing low-friction materials for water transport (Imperial College London, UK), always focusing on diverse scientific projects that would potentially bring sustainability to industrial processes. As a student in Brazil, she engaged in volunteering activities focused on environmental education and took part in the Millennial Development Goals meetings held at the university.
