MDPI INSIGHTS: The CEO's Letter #30 - Scaling with Integrity, Highly Cited Researchers, KEMÖ Consortium, Michele Parrinello, and Best PhD Thesis Awards
Welcome to the MDPI Insights: The CEO's Letter.
In these monthly letters, I will showcase two key aspects of our work at MDPI: our commitment to empowering researchers and our determination to facilitating open scientific exchange.
Opening Thoughts
With colleagues at MDPI headquarters in Basel, representing the people behind our global growth and shared commitment to integrity.
Scaling with Integrity: A Year of Growth, Responsibility, and Trust
When I look back on 2025, one phrase seems to sum up the year: “Scaling with integrity.” That was our watchword for 2025, and it will remain so as we move forward in to 2026.
Our journal portfolio continued to grow in 2025, reflecting the trust of a widening proportion of the scholarly community.
Today, MDPI has 355 journals indexed in Scopus and 330 in Web of Science – a testimonial to the scale at which our journals meet established external quality criteria. During the year, 45 of our journals were newly accepted into Scopus and 29 into Web of Science (this excludes transferred journals to our portfolio that were already indexed), following rigorous, independent evaluation by the world’s leading indexing bodies
Meeting external quality benchmarks
These results underline the fact that scaling responsibly is not only about expanding our catalogue, but also about meeting external quality benchmarks consistently, transparently, and at scale. Our indexing performance remains one of the strongest independent validations of MDPI’s commitment to rigor, trust, and long-term sustainability.
Over the course of 2025, we made targeted investments to ensure that the integrity of our editorial process scaled to keep pace with our growth. We strengthened our editorial governance by doubling down on our dedicated Publication Ethics department, appointing a Head of Ethics, and expanding our research integrity team by the addition of new specialists plus the creation of embedded editorial ethics roles across key journals. We also introduced new internal ethics guidelines, pre-review integrity checks, and monitoring dashboards to help teams identify potential issues and apply consistent standards across our portfolio.
Besides investing in systems and tools, we of course also invested heavily in our people and culture, delivering organisation-wide training on topics such as image integrity, AI use in publishing, and ethical oversight, while actively engaging with the wider publishing community through COPE and STM forums.
All these efforts reflect a simple principle: growth only matters if it is matched by rigor, responsibility, and trust.
Technology and AI: Supporting the editorial decision-making process
At MDPI, AI is designed to assist, not replace, editorial decision-making. It is one element in a broader system that combines people, technology, and processes to support scale responsibly.
In 2025, we continued to invest heavily in technology that supports quality rather than shortcuts. Our AI team doubled in size, ensuring that increased automation goes hand-in-hand with expertise and oversight. Proprietary AI tools such as Scholar Finder have significantly improved the precision of reviewer matching, while Ethicality has been widely adopted across editorial workflows to identify contextual signals, such as scope alignment and citation behaviour, so that human judgment can be applied where it matters most.
Partnerships: Institutional Open Access Program (IOAP) agreements and Societies
Our recent growth is also reflected in the strength of our partnerships. In 2025, we entered into more than 150 new IOAP agreements, bringing our total to 975 active agreements worldwide. This activity included the signing of our first-ever consortium agreements in North America, renewals of all major national consortia in the UK, Switzerland, Sweden, Norway, Austria, and Croatia, and the conclusion of several flat-fee agreements. At the same time, we concluded a total of 30 agreements, encompassing 24 new Society affiliations, four strategic publishing partnerships, and two journal acquisitions.
In 2025, we opened MDPI USA in Philadelphia – our latest global office, which complements our Toronto office in representing North America. MDPI USA is responsible for accelerating Open Access in the US through ongoing support of our scholars and for expanding our institutional and society partnerships.
On the other side of the globe, meanwhile, we signed an IOAP agreement in India, allowing researchers discounted Article Processing Charges (APCs), streamlined APC management for universities, and visibility into submissions, supporting India’s push for wider Open Access by offering flexible models and helping institutions meet national mandates such as Plan S.
Sustainability, sponsorships and awards
We continued to expand our sustainability efforts during 2025, hosting the 11th World Sustainability Forum, awarding CHF 125,000 in sustainability-related funding, and launching the Z-Forum on Sustainability and Innovation conference, which will officially take place in January 2026.
We also saw a record year for conference sponsorships and awards (while establishing new awards such as the Michele Parrinello Award), recognising scholars across disciplines and reinforcing our commitment to supporting the global research community at every stage of the academic journey.
Deepening our relationships
In 2025, I had the opportunity to travel more widely than ever before on MDPI business, meeting many of our stakeholders face to face and relishing the opportunity to gain a deeper understanding of their science communication needs. It was also excellent to visit a large number of MDPI offices and witness the commitment and service orientation of so many of our colleagues around the world. I shall resume my itinerary in the new year, and I look forward to many more such interactions.
Looking ahead to 2026, we will be celebrating a very significant milestone: 30 years of MDPI. From our foundation as a single Open Access journal in 1996 to the global publishing organisation we are today, our mission has remained consistent: advancing Open Access through rigorous and trustworthy scientific communication.
I would like to take this opportunity to thank all our stakeholders – authors, Editors-in-Chief, Editorial Board members, and reviewers – who have placed their trust in us during 2025. On behalf of the entire MDPI team, I look forward to deepening our relationships yet further in 2026 and celebrating 30 Years of Open Science at MDPI, something we’ve built together.
Basel, Switzerland, where MDPI was founded in 1996.
Impactful Research
621 MDPI Editors Named Highly Cited Researchers in 2025
I am pleased to share an important milestone for our editorial community and for MDPI. In late November, Clarivate announced the 2025 Highly Cited Researchers, and 621 MDPI Editorial Board Members were included among the most influential scientific contributors over the past decade!
The 621 editors come from 33 countries, representing 21 scientific disciplines, and account for nearly one in every ten Highly Cited Researchers globally. This recognition speaks to the depth of expertise across our Editorial Boards and the strength of the scientific communities that choose to collaborate with MDPI. It is important to note that while citation metrics are not in themselves a proxy for quality, they do offer one lens on sustained scientific influence.
“Our strength comes from the scientific communities who choose to work with us”
Why this is important
Having more than 600 editors recognized on this list highlights:
- The high level of expertise guiding peer review across our journals
- The global and disciplinary diversity within our Editorial Boards
- Our commitment to maintaining strong, knowledgeable, and engaged editorial oversight
Impactful science is of course shaped by broad, diverse research communities, and no single metric captures the full picture of research quality. However, this recognition does serve as meaningful, independent affirmation of the calibre of many editors who contribute to MDPI’s work.
A closer look at the recognition
Clarivate’s methodology highlights researchers whose publications rank in the top one per cent by citation count, reflecting consistent influence over the past decade. The process includes:
- Evaluation of c. 200,000 highly cited papers
- Removal of retracted publications
- Filtering of papers with unusually large authorship groups to focus on clear contributions
That so many of our editors meet these thresholds reflects the impact of the communities behind our journals.
What this means going forward
This recognition underlines the fact that our strength comes from the scientific communities who choose to work with us.
For authors, partners, and readers, it confirms that:
- MDPI journals benefit from editorial guidance grounded in active, high-impact research
- Our Editorial boards include leaders who are helping shape the future direction of their fields
- MDPI continues to attract experts who value openness, efficiency, and scientific integrity
For our internal teams, it is a reminder that the work we do every day (supporting editors, refining workflows, and improving systems) directly contributes to the trust placed in MDPI by researchers worldwide.
Thank you to all our editorial teams, publishing staff, and journal relationship specialists, and to everyone who collaborates with our Editorial Boards. Achievements like this are only possible because of your ongoing hard work, dedication, and collaboration.
From our first annual MDPI UK Summit in Manchester, bringing together over 30 Chief Editors and Editorial Board Members to discuss MDPI’s mission, achievements, and collaborations in the UK.

Professor Parrinello’s work has fundamentally reshaped how scientists model matter at the atomic scale. Together with Roberto Car, he introduced ab initio molecular dynamics, widely known as the Car–Parrinello method, opening new pathways in electronic structure calculations and molecular simulations. His subsequent contributions, including the Parrinello–Rahman method and metadynamics, have become core tools across physics, chemistry, materials science, and increasingly biology.
“Do not be afraid of new things. I see it many times when we discuss a new thing that young people are scared to go against the mainstream a little bit, thinking, ‘What is going to happen to me?’ and so on. Be confident that what you do is meaningful, and do not be afraid, do not listen too much to what other people have to say.”
– Professor Michele Parrinello
A global, community-led award
The award committee is chaired by Xin-Gao Gong, Professor of Physics at Fudan University and academician of the Chinese Academy of Sciences.
The Institute for Computational Physical Sciences at Fudan University will serve as the supporting institute, reinforcing the award’s international and cross-cultural foundation.
Nominations for the first edition of the Michele Parrinello Award opened on 1 November 2025, with submissions accepted until March 2026. The award will recognize scientists whose work has advanced computational physical science across physics, chemistry, and materials research – fields increasingly central to energy, sustainability, advanced manufacturing, and technological innovation.
Why this matters for MDPI
The Michele Parrinello Award is part of the MDPI Sustainability Foundation, which supports science as a driver of long-term societal progress.
Alongside other foundation-level honours, including the World Sustainability Award, the Emerging Sustainability Leader Award, and the Tu Youyou Award, this new prize builds on our role in supporting excellence across career stages and disciplines.
MDPI journals and programs continue to recognize researchers through Best Paper Awards, Young Investigator Awards, Travel Awards, Best PhD Thesis Awards, and Outstanding Reviewer Awards.

1. “Applications of Nanoporous Gold in Therapy, Drug Delivery, and Diagnostics” Cover Story: Nanoporous gold (np-Au) is emerging as an important nanomaterial in drug delivery, diagnostics and therapeutics. Np-Au offers a tunable pore size, biocompatibility and ease of fabrication into thin films, particles or shapes such as cylinders. The material can serve as a host for drug molecules with adjustable release for use in implanted devices. The plasmonic properties of np-Au enable applications in the photothermal therapy of cancer and also in diagnostic sensor development. Np-Au is an excellent electrode material for use in sensitive electrochemical detection schemes for biomarkers. |

2. “Effects of B and Ce Grain Boundary Segregation on Precipitates in Super Austenitic Stainless Steel” Cover Story: The precipitation of a Cr- and Mo-rich σ phase in super austenitic stainless steel (SASS) seriously affects the steel’s thermoplasticity and corrosion resistance. A new air-cooling and low-temperature diffusion treatment method was adopted, its purpose being to inhibit these precipitates. Ce inhibited the nucleation of the precipitates, while B induced the formation of Mo-rich precipitates and precipitates containing B and Mo, with the B-containing precipitates being serrated. The formation of B-containing serrated precipitates diminished the Cr-depleted zone near the grain boundary. The addition of B and Ce could lead to a significant improvement in the corrosion resistance of S31254 SASS. |
|
|
3. “Effect of Laser Shock Peening on the Stress Corrosion Cracking of 304L Stainless Steel” Cover Story: Laser shock peening (LSP) was performed on 304L stainless steel, and the SCC properties were evaluated via the U-bend test in 42% MgCl2. LSP induced a residual compressive stress in the depth direction and a grain refinement and an increased pitting potential of the cross section, and thus, the total and net crack propagation rates were reduced. Based on multiple regression analysis, the relationship between residual stress and crack propagation rates was strong, but the relationships between the average grain size and pitting potential of the cross section and crack propagation rates were moderate and weak, respectively. |
|
|
4. “Study on the Bath Smelting Reduction Reaction and Mechanism of Iron Ore: A Review” Cover Story: Bath smelting reduction technology is globally favored as a non-blast-furnace ironmaking technology that directly reduces iron ore into liquid metal without using coke as the raw material. This work focuses on three key aspects of smelting reduction, namely the thermal decomposition characteristics of iron ore during smelting reduction, the smelting reduction mechanism of iron-ore particles, and the smelting reduction mechanism of FeO-bearing slag. The experimental study methods, reaction mechanisms, influencing factors, and kinetic behavior of the three are highlighted to help foster a better understanding of the nature of the bath smelting reduction reaction. |
|
|
5. “Microstructural Evolution of a High-Strength Zr-Ti-Modified 2139 Aluminum Alloy for Laser Powder Bed Fusion” Cover Story: A precipitation-hardening Al2139 alloy doped with additions of Zr and Ti was printed via laser powder bed fusion (L-PBF) and subsequently exposed to temperatures up to 300 °C. The relationship between performance degradation and changes in material structure was investigated through microhardness monitoring and microstructure analysis. The fully equiaxed fine-grained as-built state exhibits micro-segregations of Cu and Mg at the grain boundaries. These disappeared after the optimized T4 heat treatment, which formed rod-shaped Zr- and Ti-based second phases and quasi-spherical Cu-, Mn-, and Fe-rich particles. High-temperature holding leads to the rearrangement and subsequent spheroidization of Cu- and Mg-rich particles at the grain boundaries. |
|
|
6. “Ranking of Injection Biochar for Slag Foaming Applications in Steelmaking” Cover Story: EAF has the potential to decarbonize the steel industry. Carbon needs to be injected into molten slag for slag foaming in EAF steelmaking. Biocarbon is gaining attention as an alternative to fossil carbon. Two biochar candidates were tested in an induction furnace to simulate EAF conditions. The slag foaming height was measured and compared to fossil carbon candidates. The results show that biochar has considerable slag foaming capacity, specifically in bio-briquette forms. Ongoing research aims to develop a standardized methodology for ranking and qualifying different biochar candidates for larger-scale use. |
|
|
7. “Study on the Wear Resistance of Ni-Co-ZrO2 Composite Coatings with Different ZrO2 Nanoparticle Concentrations Prepared Using Electrodeposition on the Micro-Surface of Spindle Hook Teeth” Cover Story: To improve the wear resistance of the surface of the cotton picker spindle, a Ni-Co-ZrO2 composite coating doped with ZrO2 nanoparticles was prepared via electrochemistry on the microsurfaces of spindle hook teeth. The effects of different ZrO2 nanoparticle concentrations on various parameters of the coating were discussed. The test results indicated that Ni-Co-ZrO2 composite coatings featured a more compact coating structure, a greater coating thickness, and a smaller grain size. The presence of ZrO2 nanoparticles led to further improvements in the coating’s wear resistance. When the mass concentration of ZrO2 nanoparticles reached 4 g/L, the wear resistance reached its highest level. |
|
|
8. “Microstructural Characterization of Reactor Pressure Vessel Steels” Cover Story: Ion irradiation is a promising tool for emulating neutron-irradiation effects on reactor pressure vessel (RPV) steels. Comprehensive microstructure characterization was performed by means of different electron microscopies. The main work was based on scanning transmission electron microscopy applied to cross-sectional samples prepared using the focused ion beam technique to investigate ion irradiation-induced loops. Two different types of RPV steels with two levels of ion displacement damage were compared. Furthermore, a comparison was performed with the same samples previously irradiated with neutrons, and the results were discussed. |
|
|
9. “Aging Behaviour of a 12.2Cr-10Ni-1Mo-1Ti-0.6Al Precipitation-Hardening Stainless Steel Manufactured via Laser Powder Bed Fusion” Cover Story: The effect of solution annealing on the microstructure, aging, and over-aging behaviour of a precipitation-hardening stainless steel (PHSS) manufactured via laser powder bed fusion (LPBF) was investigated. Despite the different microstructures in the as-built and solution annealed conditions, the steel exhibited the same peak hardness, aging, and over-aging behaviour, which was related to nanometric precipitates and martensite-to-austenite reversion. Therefore, solution annealing on LPBF-manufactured PHSS is not mandatory in order to achieve high hardness and thermal stability, which are required for plastic injection moulding applications, thus enabling the production of complex tools with conformal cooling channels, hardened through simple direct aging treatment. |
|
|
10. “Effect of Magnet Alternate Stirring on the Internal Quality of Sn-Pb Alloy” Cover Story: A permanent magnet stirrer was built to study the effect of different magnetic field stirring modes on the solidification quality of Sn-20 wt-% Pb alloy ingots. The internal quality of the ingot can be improved by adjusting both the stirring speed and the modes. In this paper, a permanent magnet stirrer was developed instead of an electromagnetic stirrer, and a Sn-20%Pb alloy was used instead of steel. Furthermore, the effects of different magnetic field stirring modes on the solidification structure and element uniformity of the alloy ingots were studied. |
|
|
11. “Fast Gold Recovery from Aqueous Solutions and Assessment of Antimicrobial Activities of Novel Gold Composite” Cover Story: The design and development of antibacterial polymer-supported materials, which can be easily functionalized, could improve their antimicrobial properties due to the synergistic effect between nanoparticles and the polymer matrix and solve the nanoparticle aggregation problem. In this study, a novel porous gold polymer composite was prepared via the functionalization of glycidyl methacrylate-based copolymers with ethylene diamine (pGME-en) and was demonstrated to be a rapid adsorbent for gold from aqueous solutions. Furthermore, the subsequent use of this versatile sorbent as an antimicrobial agent was investigated. |
|
|
12. “Evaluation of the Applicability of Voltammetric Modes in Scanning Electrochemical Microscopy for In Situ Corrosion Characterisation of Copper-Based Materials” Cover Story: The introduction of scanning electrochemical microscopy (SECM) into the study of corrosion reactions and mechanisms provides interesting insights on initiation events and their dissemination with chemical and spatial resolution. More recently, its applicability has expanded thanks to methodological and instrumental developments that allow the combination of SECM with other spectroscopic, scanning probe microscopy, or electrochemical techniques to collect information on even earlier time scales and from systems with smaller differences in local chemical reactivity. This work shows the effectiveness of combining SECM with electrochemical voltammetry techniques to monitor in situ metal dissolution processes associated with the acidic corrosion of copper-based materials. |
