About Professor Michele Parrinello

"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

Born in Messina in 1945, he received his degree from the University of Bologna and is currently affiliated with the Italian Institute of Technology. Professor Parrinello is known for his many technical innovations in the field of atomistic simulations and for a wealth of interdisciplinary applications ranging from materials science to chemistry and biology. Together with Roberto Car, he introduced ab initio molecular dynamics, also known as the Car–Parrinello method, marking the beginning of a new era both in the area of electronic structure calculations and in molecular dynamics simulations. He is also known for the Parrinello–Rahman method, which allows crystalline phase transitions to be studied by molecular dynamics. More recently, he has introduced metadynamics for the study of rare events and the calculation of free energies.

For his work, he has been awarded many prizes and honorary degrees. He is a member of numerous academies and learned societies, including the German Berlin-Brandenburgische Akademie der Wissenschaften, the British Royal Society, and the Italian Accademia Nazionale dei Lincei, which is the major academy in his home country of Italy.

We are pleased to share an interview with Mr. Pietro Tordi, from the Université de Strasbourg & CNRS, France, who received the Best Oral Presentation Awards at the 4th International Online Conference on Materials (IOCM 2025).

1. Could you give a brief introduction of yourself to the readers?
I carried out my PhD studies through a cotutelle program between the University of Florence, Italy, and the University of Strasbourg, France. I am currently close to defending my PhD thesis and work as a researcher at the Institut de Science et d’Ingénierie Supramoléculaires (ISIS), within the Nanochemistry Lab led by Professor Paolo Samorì. My research focuses on the design of biopolymer-based soft materials for wearable electronics and energy-related applications, at the intersection of soft matter, ionic materials, and functional devices. In particular, I am interested in how molecular and ionic interactions can be engineered to achieve adaptive and multifunctional behavior.

2. What inspired your interest in materials research, and how has your focus developed over time?
I was initially drawn to materials research by the idea that subtle changes at the molecular level can lead to dramatic differences in macroscopic properties. Over time, my focus shifted toward soft and bio-derived materials, particularly hydrogels and organohydrogels, because they offer a unique platform where chemistry, mechanics, and ion transport are deeply interconnected. This evolution naturally led me to soft electronics, where materials design directly defines device performance.

3. What was your experience of attending the 4th International Online Conference on Materials? Do you have any further suggestions?
I found the conference to be a very engaging and well-organized experience, offering a clear and accessible forum to share research across a wide range of materials science topics. The online format was particularly effective in enabling participation from an international and diverse audience. Looking ahead, incorporating additional live discussion moments or focused thematic sessions could further enhance interaction and scientific exchange among participants.

4. When and how did you first become aware of the open access Materials journal? How do you think open access impacts scholars like yourself?
I became familiar with Materials during the early stages of my PhD through its strong coverage of hybrid polymer- and biopolymer-based materials, particularly in the context of functional and electronic applications. For early career researchers working at the interface of chemistry, soft matter, and devices, open access is especially valuable, as it enhances visibility and accessibility while enabling rapid dissemination of interdisciplinary research. This facilitates broader engagement across communities that may not traditionally interact, accelerating scientific exchange.

5. What was the most challenging aspect of designing and conducting this study?
A central challenge was integrating mechanical softness with well-controlled ionic transport within a single material platform. Achieving high stretchability while maintaining stability and functional responsiveness required precise control over material composition and crosslinking chemistry. An additional challenge was ensuring that these molecular design strategies translated reliably into reproducible, device-relevant performance.

6. What message would you share with fellow early career researchers navigating similar paths?
I would encourage early career researchers to pursue research topics they genuinely enjoy, even when the path is not always straightforward. Staying motivated over time often depends on personal curiosity and interest. I also believe that traveling, attending conferences, and meeting researchers from different backgrounds are essential, not only to build a network but also to gain new perspectives and generate fresh ideas that can shape one’s scientific direction.

7. How do you see this award supporting your future work or goals?
This award is a meaningful encouragement to continue developing research at the interface of fundamental materials design and functional applications. It also reinforces the importance of clear scientific communication and visibility, motivating me to further advance sustainable and multifunctional materials for next-generation soft electronic systems.

“Modified Fine Recycled Concrete Aggregates with a Crystallizing Agent as Standard Sand Replacement in Mortar”
by Daniel Suarez-Riera, Luca Lavagna, Devid Falliano, Giuseppe Andrea Ferro, Matteo Pavese, Jean-Marc Tulliani and Luciana Restuccia
Materials 2025, 18(17), 4208. https://doi.org/10.3390/ma18174208

The following is an interview with Prof. Dr. Jean-Marc Tulliani:

1. Congratulations on your published paper! Could you please briefly introduce its main research content?
This study aimed to evaluate mortar performance by partially replacing standard sand with recycled fine aggregates derived from concrete waste in order to assess their mechanical properties and durability. In addition, the use of commercial crystallizing agents was investigated to evaluate their impact on mortar properties. While coarse recycled aggregates have already been treated with active substances that react with hydration products or unhydrated cement particles to fill pores and cracks, this approach has not, to the best of our knowledge, been applied to fine recycled aggregates. Therefore, the present work proposes a novel approach to enhance the environmental and mechanical performance of mortars containing varying contents of recycled fine aggregates pre-treated with crystallizing agents.

2. What are the key takeaways you hope readers will gain from your paper?
In most cases, mortars incorporating recycled aggregates exhibited higher strength than those prepared with standard sand. The 25% and 50% replacement levels, in combination with the use of the crystallizing agent, were particularly effective, leading to strength gains of up to 15% compared with the reference mortar, without requiring superplasticizer dosages beyond conventional levels. Conversely, mortars produced with recycled sand treated with crystallizing agents demanded higher superplasticizer contents to achieve equivalent workability, which can potentially limit their practical interest. Overall, these results demonstrate that substantial replacement of natural sand with recycled concrete aggregates, enhanced through a simple treatment using commercially available products, can yield mechanical performance comparable to or superior to that of conventional mortars. This approach offers a viable and effective pathway for promoting resource efficiency and advancing circular economy practices in the construction sector.

3. Was there a specific experience or event in your research career that led you to focus on your current field of research?
Yes, of course. The concept originated from previous works on self-healing concrete, where commercial crystallizing agents are already used in practice to seal cracks in damaged structures. Extending this proven technology to fine recycled aggregates, which are inherently more porous than natural aggregates, represents a logical and potentially impactful step toward improving their performance and industrial usability.

4. Does technological progress provide new opportunities for the topic you are researching? Does it bring any potential risks? How do you think these factors will affect future research trends on this topic?
Since 2015, we have been investigating the incorporation of biochar into cementitious materials with the aim of enhancing their mechanical properties while reducing their carbon footprint. Initial experimental works focused on laboratory-produced biochar derived from various feedstocks. However, the increasing availability of industrial-scale pyrolysis facilities and commercially produced biochar now enables the transition toward large-scale production. As all biochar are not equivalent for the targeted application, either from a physical or a chemical point of view, further investigations are still needed. Nevertheless, this development will pave the way for the industrial manufacturing of biochar-based concretes and their application in buildings and infrastructure.

5. What was it about the Materials journal that appealed to you which made you want to submit your paper? In your opinion, what can authors expect when they submit to Materials?
Materials was chosen as the publication outlet based on several institutional considerations. It is a well-established, peer-reviewed journal in materials science whose scope is fully aligned with the objectives of the present research, and which ensures wide dissemination within the scientific community. Furthermore, the journal offers an efficient editorial and peer-review process, enabling timely decisions and rapid communication of research outcomes. Finally, previous publication experience with Materials, starting in 2013 to be exact, has demonstrated a consistently high standard of editorial management, as well as strong accessibility and quality for the readership.

6. How do you think the open access way of publishing impacts authors?
Open access publishing has evolved from a marginal and sometimes mistrusted practice to a widely accepted model in academia. Despite remaining challenges such as article processing charges, it is generally viewed as a positive development that enhances the accessibility, visibility, and impact of research. Supported by funding institutions and associated with higher citation rates, open access is expected to continue expanding and to play a central role in scientific publishing across disciplines.

“Towards a New Plastination Technique for Moisture Management of Western Red Cedar Without Loss of Strength and with Enhanced Stability”
by Olivia H. Margoto, Madisyn M. Szypula, Grant R. Bogyo, Victor Yang and Abbas S. Milani
Materials 2025, 18(18), 4353; https://doi.org/10.3390/ma18184353

The following is an interview with Ms. Olivia H. Margoto and Dr. Grant R. Bogyo:

1. Congratulations on the publication of your paper. Could you briefly introduce the main content of your paper?
In this paper, we investigated plastination as a novel technique for managing moisture in Western Red Cedar, a widely used construction wood that is inherently vulnerable to moisture absorption and biodegradation. Borrowing a technique originally developed for biological tissue preservation, the proposed approach combines acetone dehydration with vacuum-assisted impregnation using a silicone, followed by curing, to replace water within the wood microstructure with a hydrophobic polymer.
The study focused on evaluating both the effectiveness of SS-151 silicone impregnation and its impact on moisture resistance and mechanical performance. Micro X-ray Computed Tomography imaging was used to see how deeply the silicone penetrated the wood, while chemical analysis and water absorption tests examined changes in the wood’s composition and moisture resistance. Mechanical tests before and after moisture exposure assessed the wood’s strength and flexibility. Results showed successful silicone penetration, reduced water-attracting chemical groups, significantly lower moisture absorption, and preserved tensile strength with improved deformability.

2. What are the key takeaways you hope readers will gain from your paper?
The key takeaway is the strong potential of plastination as a new strategy to protect natural materials such as bamboo and wood without sacrificing their mechanical performance. In this study, plastinated Western Red Cedar exhibited 59% lower moisture absorption compared to conditioned virgin samples, while retaining tensile strength and exhibiting improved deformability. These results highlight how plastination can significantly mitigate moisture-driven degradation, enabling the use of natural materials like wood in more demanding outdoor and structural applications.
More broadly, this work shows that bio-based materials can be engineered for enhanced durability through innovative and cost-effective approaches. As such, plastination emerges as a promising technique for sustainable construction, particularly in environments where moisture-related degradation has historically limited the use of natural fibers and softwood.

3. Was there a specific experience or event in your research career that led you to focus on your current field of research?
The experience that led me to focus on natural fiber preservation occurred several years ago when I assisted a colleague in General Santos City, in the Philippines, with a drainage challenge. Conventional construction materials such as rebar were prohibitively expensive, while bamboo was abundant. When I asked why bamboo was not being used structurally, a local engineer explained that its susceptibility to mold, moisture, insects, and rot made it unsuitable.
This question stayed with me. Months later, while attending a conference in Las Vegas, I visited the Bodies Exhibition. Observing the plastinated anatomical specimens, I had a moment of clarity: the preservation principles used in plastination might offer a pathway to stabilizing natural fibers, including wood and bamboo, for engineering purposes. That insight ultimately led to the development of our patented plastination approach and the research now being published.

4. Could you describe the difficulties and breakthrough innovations encountered in your current research?
Under the guidance of Dr. Abbas Milani at the University of British Columbia in Canada, and through the rigorous experimental work of doctoral candidate Ms. Olivia Margoto, our team identified a set of low-molecular-weight polymers that offered promising performance at significantly lower cost than traditional silicones used in classical plastination.
Key challenges included optimizing polymer selection, impregnation parameters, curing conditions, and processing time. Through systematic experimentation, the team achieved stable and repeatable results, decreasing the processing time by 38%. We are now evaluating next-generation polymers that may further enhance moisture resistance while maintaining or improving the mechanical strength of natural materials with microstructures even smaller than that of cedar wood.
Ms. Margoto’s contributions were essential—her experimental precision, data interpretation, and
ability to translate theoretical polymer behavior into practical laboratory outcomes were central
to the breakthroughs reported.

5. Does technological progress provide new opportunities for the topic you are researching? Does it bring any potential risks? How do you think these factors will affect future research trends on this topic?
Advances in artificial intelligence will increasingly support polymer discovery and theoretical modelling. AI can help identify promising polymer candidates by predicting molecular behavior, cost-performance relationships, and compatibility with botanical substrates.
However, botanical materials exhibit substantial natural variability—between species, between samples, and even within individual specimens. This limits the predictive power of computational models. Empirical testing, engineering judgment, and hands-on experimentation will remain indispensable components of the research process. Future progress will likely emerge from a hybrid approach that combines AI-assisted modelling with rigorous laboratory validation.

6. How do you evaluate research trends in this field, and what advice would you give to other young researchers?
Sustainability is a global priority, and materials science plays a pivotal role in advancing it. My advice to young researchers is to balance digital tools with real-world engagement. Spend time observing natural materials, understanding their behavior in practical contexts, and solving tangible problems - then bring those insights back to the laboratory.
Experiences in developing regions can be especially transformative, offering perspectives that enrich both scientific inquiry and personal purpose. A purpose-driven approach often leads to solutions that are not only innovative but also sustainable and socially meaningful.
