“Do Not Be Afraid of New Things”: Prof. Michele Parrinello on Scientific Curiosity and the Importance of Fundamental Research

In atomic and molecular simulation, researchers have long-needed efficient ways to predict material properties in order to focus on the most promising real laboratory tests instead of redundant work. Addressing this challenge, Prof. Michele Parrinello introduced two transformative methods that have redefined the field: the Car–Parrinello method, which serves as a “virtual lab” for studying reactions and electronic properties, and the Parrinello–Rahman method, a cornerstone for crystal phase transition studies. His work has reshaped the way that we study atomic systems, earning him the status of one of the most cited scholars in his field.
To honor his enduring legacy and continued impact, MDPI has established the Michele Parrinello Award. This award celebrates innovation and recognizes senior scientists who have made outstanding contributions to computational physical sciences, spanning the fields of physics, chemistry, and materials science.
We had the great honor of speaking with Prof. Parrinello in an exclusive interview, where he shared his perspectives on his current research focus, personal scientific experiences, support for basic research, and his advice for global researchers.

Open Access, Broadly Recognized: 363 MDPI Journals Receive CiteScores for 2025
The 2025 CiteScore metrics have been officially released by Scopus, and the results confirm what has become a consistent pattern for MDPI's journal portfolio: broad recognition across disciplines, steady improvement across the majority of ranked titles, and a growing presence at the top of subject category rankings.
CiteScore, published annually by Elsevier's Scopus database, measures the average citations received by articles published in a journal over a four-year window. As a complement to the Journal Impact Factor, which uses a two-year window based on the Web of Science database, CiteScore provides an alternative, long-term perspective on citation performance.
The 365 MDPI journals in Scopus (as of May 2026) are indexed across a wide range of subject categories, ensuring that open access research remains highly discoverable to a global readership through one of the most widely used platforms in academic publishing.
Data Summary (2025 CiteScores)
- New Additions: 41 MDPI journals received a CiteScore for the first time.
- Trending Upward: 234 of 322 previously ranked journals (73%) saw an increase in their CiteScore compared to last year.
- High Visibility: 314 journals (86%) rank in Q1 or Q2 in at least one subject category.
- Elite Performance: 42 journals rank in the top 10% of their subject categories.
Portfolio Performance
Among the 322 journals that held a CiteScore in 2024, 234 saw an increase this year. Quartile improvements outnumbered declines across the portfolio, with 52 journals moving to a higher quartile and only 20 seeing a decline. Furthermore, no previously ranked journals were removed. The 42 journals now ranked in the top 10% of their subject categories are drawn from a strong foundation of 178 journals holding a Q1 position.
With the large majority of our indexed portfolio ranked in the top half of research fields, researchers can confidently choose MDPI to meet funder mandates for high-quality, fully compliant Open Access publishing.
Exceptional Achievements for Foods and Life
Notably, both Foods and Life achieved a 99th percentile ranking in their respective subject categories for the 2025 CiteScores. This outstanding placement positions them as leading journals in their fields and highlights the high visibility and global impact of the open access research they publish.
Journal Metrics and Beyond
Journal-level metrics describe outlets, not individual articles. An increasing number of funders and institutions—including signatories of DORA and the Coalition for Advancing Research Assessment—now explicitly encourage evaluation at the article level rather than by the journal in which research appears. MDPI supports this direction: we report CiteScore alongside the Journal Impact Factor, Journal Citation Indicator, and article-level usage data because no single number captures the full reach and contribution of published research.
Thank You
These results reflect the sustained effort of thousands of editors-in-chief, editorial board members, reviewers, and authors across every field MDPI serves. The metrics are the outcome; the work is yours.

Inside MDPI

Open Access Policies Continue to Accelerate Globally
One of the clearest indicators of the continued momentum behind open access is the growing number of national and institutional policies supporting, and increasingly requiring, open dissemination of research.
Around the world, governments, funding agencies, and universities are building their open access mandates, with increasing focus on transparency, rights retention, and public accessibility of publicly funded research. While these policies vary across regions, the broader direction is clear: expectations around openness and compliance continue to accelerate.
For researchers, navigating these evolving requirements can be complex and time-consuming. Supporting the research community therefore means not only publishing high-quality open access content but also helping stakeholders better understand changing requirements and emerging opportunities. At MDPI, we see this as an important part of our role within scholarly communication.
“Expectations around openness and compliance continue to accelerate”
Through the MDPI Blog, our Content team continues to publish monthly articles overviewing different countries’ relationships with open access, exploring their histories, policies, opportunities, and statistics. All this information is centralized into an article which contains brief summaries of each country, with links to all the full articles, and is updated monthly.
Recent Policy Developments
South Africa
In 2026, South Africa’s Department of Science and Innovation introduced the South African Open Science Policy. The policy states that: “Open access shall be required for publications arising from publicly funded research, and desirable for research from all sources of funding.”
The policy envisions a coordinated and broad approach to open science that will sustainably and ethically drive socio-economic development by increasing the practice of open science through policy, training, incentivization, and infrastructure.
Canada
In Canada, the Tri-Agency OA Policy on Publications was revised, removing the 12-month embargo for research that must be deposited in a repository with an open license and with author rights retained.
The Agencies argue that “societal advancement is made possible through widespread and barrier-free access to cutting-edge research and knowledge.”
Chile
Chile is a collaborative and engaged member of the global open access movement.
The National Research and Development Agency (Agencia Nacional de Investigación y Desarrollo, or ANID) is Chile’s main funding agency for R&D. It mandates that all beneficiaries must deposit the final version of their published scientific output, with an embargo period of up to 12 months, into a repository.
ANID also supports the InES Open Science funding program, which allows universities to request funding for capacity and infrastructure building. Further, Chile is an active participant in various international initiatives, such as Redalyc, SciELO, and Red de Repositorios Latinoamericanos.
Openness Beyond Research
At MDPI, openness remains one of our core values, ensuring that research outputs are freely accessible to anyone. This commitment also extends to sharing knowledge about the scholarly publishing landscape itself, which we practice on the MDPI Blog through various topics, including open access, recent advances in science, and opportunities for researchers.
As the open access landscape continues to evolve, helping researchers, institutions, editors, and partners navigate these changes will remain an important priority for us.

Thank You
I would like to thank Jack McKenna (Senior Content Specialist, MDPI) from our Content team for his ongoing work on the MDPI Blog series covering global open access policy developments. Initiatives such as this help make complex policy discussions more accessible and useful to the wider research community.

Nanomaterials | Behind the Paper: Enzyme-Responsive Gadolinium Oxide Nanoparticles for Cancer Theranostics
In this Behind the Paper interview, we speak with Ms. Xingchen Wang, first author of a recent article published in Nanomaterials (ISSN: 2079-4991). Ms. Wang shares her perspective on the motivation behind the study, the design of the nanoparticle platform, the role of MMP-responsive drug release, and potential next steps for dual-imaging-guided cancer nanomedicine.
About the Paper:
“Biocompatible Gadolinium Oxide Nanoparticles Incorporated Doxorubicin Enables Magnetic Resonance and Photoacoustic Dual Imaging for Cancer Theranostics”
by Xingchen Wang, Yuta Imai, Yu Kimura, Risako Miura, Hirohiko Imai and Teruyuki Kondo
Nanomaterials 2026, 16(6), 343; https://doi.org/10.3390/nano16060343
About the Author:
Ms. Xingchen Wang is a PhD candidate at the Graduate School of Engineering, Kyoto University. Her doctoral dissertation focuses on the fusion of nanotechnology and cancer theranostics. She specializes in the development of highly biocompatible gelatin-coated Gd2O3 nanoparticles for target drug delivery and dual modality imaging. She uses enzyme-responsive nanomaterials to bridge the gap between accurate diagnosis and effective treatment. She has successfully designed and developed several nanoparticle systems that utilize tumor-specific microenvironments for controlled drug release. She hopes to contribute to research on nanoparticles in engineering and further their application to medical and clinical contexts.
The following is an interview with Ms. Wang:
1. Could you briefly introduce the background of this study and explain what inspired your team to develop this gadolinium oxide nanoparticle platform for cancer theranostics?
Our team has years of research enhancing the capabilities of MRI contrast agents. Through the development of Gd nanomaterials, we have accumulated a wide range of experience, including Gd dendrimers and Gd2O3 nanoparticles. The novelty of the nano-system is that the control of size enables the ability to increase the contrast of MRI images, in vivo biological distribution dynamics, and tumor passive accumulation. Under such a background, we aimed to expand their role beyond the diagnosis of Gd nanomaterials to integrated cancer theranostics
By developing a multifunctional nano-particle platform that combines dual MRI/photoacoustic imaging and enzyme-response drug supply, we aimed to realize more accurate tumor visualization along with selective therapeutic activation in the tumor microenvironment.
2. What do you consider the main novelty of this work compared with previous gadolinium-based theranostic nanoparticles and dual MRI/photoacoustic imaging probes?
The key feature of our platform is the integration of drug release and dual MRI/photoacoustic imaging in response to tumor microenvironments. MRI provides the entire body with anatomical information about deep tissues, while photoacoustic imaging provides high spatial/temporal resolution of the specific body. By combining these modalities, our platform enables much more reliable and accurate tumor detection than using either modality alone. Furthermore, the nanoparticles are passively accumulated in the tumor through a tumor-specific EPR effect, and the gelatin on the surface of the nanoparticles is hydrolyzed by MMP-2/9 enzyme activity and anti-cancer drugs are released.
3. Your study uses MMP-responsive degradation of succinylated PEG-gelatin to trigger doxorubicin release. Could you explain why this enzyme-responsive mechanism is advantageous for selective tumor therapy?
The major advantage of our MMP-compatible design is that drug release in the tumor microenvironment is selective. MMP-2 and MMP-9 are highly secreted in various invasive solid tumors but only show extremely low activity in normal tissues. This biological differentiation allows the autonomous release of preferential anti-cancer agents to the tumor site, significantly reducing the toxicity to normal tissues. As a result, it is possible to minimize the side effects of anti-cancer drugs on normal cells.
Another significant advantage is that this mechanism continues to support visualization capabilities in MR/PA dual imaging. In vivo experiments demonstrated that tumor reduction could be tracked using these two imaging modalities, a result that would be beneficial for optimizing treatment.
4. What was the main challenge in preparing or evaluating the SPG–DOX–Gd nanoparticles, and how did your team address it?
The main challenge was to attain both sufficient stability in the physiological environment and efficient responsiveness in the tumor site. If the nanoparticle structure is too unstable, drug leaks occur before they accumulate in the tumor. Conversely, if the structure is overly stable, the drug release at the tumor site becomes inefficient. To cope with this problem, the composition and chemical modification of the gelatin shell were carefully optimized. Accordingly, the optimization process of selecting surface coatings that respond to tumor-related MMP enzymes has succeeded in establishing a nanoparticle system that efficiently releases the drug only at the tumor site, while maintaining stability under physiological conditions.
5. Could you share what made Nanomaterials a suitable venue for this work, and how you found the journal’s editorial communication, peer-review, and publication process?
We decided to submit our research because our research content was fully consistent with the Special Issue “Nanomaterials in Medicine and Healthcare” of Nanomaterials. In other words, the development of theranostic probes based on a multifunctional nano-materials platform, as well as the study on dual imaging and drug delivery, conforms to the scope of the studies covered by this journal. The peer review process was very professional, and the peer reviewers provided valuable suggestions and were able to have sufficient scientific discussions. As a result, they helped to significantly improve the quality of our manuscript. Consequently, we appreciate that our research results were shared with the scientific community in a timely manner.
