Introducing Materials Horizons’ Emerging Investigators 2020/2021 – Part 2.

This year we are pleased to celebrate the tenth anniversary of Materials Horizons. We are so grateful to our fantastic community of authors, reviewers, Board members and readers and wanted to showcase just some of them in a series of ‘Community Spotlight’ blog articles.

In our second ‘Community Spotlight’, we feature some of our past ‘Emerging Investigators’ who have contributed their outstanding research to Materials Horizons.

Our Emerging Investigators series highlights early career scientists who have excelled in their field and work to provide quality research and communications in order to contribute to the constant evolution of chemical sciences. We asked some of our past Emerging Investigators about their experience as up-and-coming researchers and how their work has developed from early career stage to now. Check out their interview responses below.

Eleni Stavrinidou is an Associate Professor and leader of the Electronic Plants group at Linköping University. She received a PhD in Microelectronics from EMSE (France) in 2014. She then did her postdoctoral training at Linköping University (Sweden) during which she was awarded a Marie Curie fellowship. In 2017 Eleni Stavrinidou became Assistant Professor in Organic Electronics at Linköping University and established the Electronic Plants group. She received several grants including a Swedish Research Council Starting Grant and a FET-OPEN grant which she was the coordinator. In 2020 she became Associate Professor and Docent in Applied Physics. The same year she was awarded the Future Research Leaders grant of the Swedish Foundation for Strategic Research. In 2021 she was awarded the ERC-Staring Grant. Stavrinidou is recipient of the L’ORÉAL-UNESCO For Women in Science prize in Sweden (2019) and the Tage Erlander Prize for Natural Sciences and Technology from the Royal Swedish Academy of Sciences (2023).  Her research interests focus on plant bioelectronics for real time monitoring and dynamic control of plant physiology and plant-based biohybrid systems for energy and sensing applications.

What inspired you to pursue a career in your specific field of research?

“I am fascinated by the potential of interfacing technological systems with biology to solve societal problems but also for pure scientific curiosity. Biological systems are beautiful but complex and can rarely be approximated into simpler ones of fully be described with physical laws. I find very inspiring the possibility to rationally manipulate biological events with technological devices but also to be able to use biological processes for development of materials or devices and harness some of nature’s intelligence in technology.”

How would you summarise the research which lead to your recognition as an Emerging Investigator for Materials Horizons?

“The research that led to my recognition from Materials Horizons is plant based biohybrid systems. Plants are amazing machines powered by the sun that can self-repair, sense, and adapt to their environment while having hierarchical structures and complex biochemistry. Plant based biohybrid systems aim to leverage plant processes and structures for technological applications.  We developed biohybrid plants with an electronic root system. We harnessed the biocatalytic machinery of intact plants to integrate electronic materials into their structure while the plants maintain their biological functions and continue to grow and develop. The integrated mixed ionic–electronic conductors maintained their functionality over weeks and as a proof of concept we demonstrated energy storage in the plant. “

What are some of the current trends or emerging areas of research within your field that you find particularly exciting or promising?

“One of my proudest research projects is the solar driven photocatalysis for hydrogen production, CO2 and N2 fixation. While previous research focus more on the powdery catalysts along with their insight reaction mechanism, now more and more attempts move to integrate the catalysts into monoliths and membranes and eventually into a realistic device, that can find more practical application in real-life deployment.”

What advice would you give to aspiring scientists who hope to make a significant impact in their respective fields?

“I would say it is always important to find fundamental breakthrough in science and technology, but it is also the ultimate goal to generate benefit out of science, namely, to translate the knowledge into true impact in the forms of prototypes, demonstrations, and even pilot plants. By doing this, scientists should seek for not only research collaborators but also industry partners to gather the expertise and experience from different parties and achieve something big.”

Chengyi Hou, a professor at Donghua University, is engaged in the development of innovative methods and experimental approaches to address the key scientific and technical challenges related to scalable synthesis, processing and assembly of smart fibres and fabrics. The novel fibre/fabric materials realize sensory and actuatory tasks like health monitoring, personal thermal management, and human-machine interaction. Their potentialities in next-generation clothing have also been explored. Chengyi Hou edited one book on smart clothing, and published over 100 peer-review journal articles on smart fibres and wearable materials, with several publications on Science, Science Advances, Nature Communications, Advanced Materials, Materials Horizons, amongst others.

What inspired you to pursue a career in your specific field of research?

“The rise of wearables. From socialization to personal health management, wearable digital devices are changing the way we experience our everyday lives. Along with everyone else I witnessed the impact of wearables in fashion, healthcare, entertainment, and many other industries. It encouraged me to keep involving in this specific field since the beginning of my career. However, there’s no guarantee that people will continue wearing digital devices over time because of barriers existing between wearables and wear. Currently, we are focusing on smart fibers, also known as fiber electronics, because it has obvious advantages in comfortability, weaveability, and wearability over bulk or thin-film devices. So, our next goal is to make wearables more wear-able.”

What are some of the current trends or emerging areas of research within your field that you find particularly exciting or promising?

“Try to imagine what will happen when all functions of a smartphone are integrated into a single fiber. Such a smart fiber represents the ultimate version of digital devices, and will revolutionize the way people live, work, and communicate. So, fiber electronics with either one or multiple digital functions including sensing, powering, displaying, and communication is extremely promising. I am also excited about the possible future of smart clothing. As our second skin, the new clothes based on smart fibers will become an intelligent interface between human and nature.”

Introducing Materials Horizons’ Emerging Investigators 2020/2021 – Part 1.

This year we are pleased to celebrate the tenth anniversary of Materials Horizons. We are so grateful to our fantastic community of authors, reviewers, Board members and readers and wanted to showcase just some of them in a series of ‘Community Spotlight’ blog articles.

In our second ‘Community Spotlight’, we feature some of our past ‘Emerging Investigators’ who have contributed their outstanding research to Materials Horizons.

Our Emerging Investigators series highlights early career scientists who have excelled in their field and work to provide quality research and communications in order to contribute to the constant evolution of chemical sciences. We asked some of our past Emerging Investigators about their experience as up-and-coming researchers and how their work has developed from early career stage to now. Check out their interview responses below.

Dr. Ignasi Fina works as tenured scientist at the Institute of Materials Science of Barcelona belonging to Spanish National Research Council. He is focused on the study of new ferroelectric materials for non-volatile applications. Ignasi Fina did his PhD in Barcelona, before working as Beatriu de Pinós fellow in Max Planck Institute of Microstructure Physics (Germany). He was also awarded with Juan de la Cierva and Ramon y Cajal fellows. He has coauthored over 120 publications, being corresponding author in nearly half of them.

What inspired you to pursue a career in your specific field of research?

“In the area of research of materials for electronics, as in any other field of research, there are many questions to be answered. The most important thing is to do is focus on the right questions and be sure that you have the right tools to answer them in the best possible manner. The electronics industry is demanding more and more new materials; able to perform better and with novel functional properties. The number of potentially interesting new materials for the electronics industry is huge.

The bottle-necks and the large number of open questions faced by the electronic industry and the fact that I have the right tools to help solve some of them, motivated me to study high quality materials in thin film form, focusing mainly on ferroelectric materials.”

How would you summarise the research which lead to your recognition as an Emerging Investigator for Materials Horizons?

“I work with outstanding quality materials thanks to the work of my colleagues and the developing techniques that we use. These outstanding quality materials are difficult to be directly integrated in commercial devices due to their very demanding fabrication. However, high quality materials are excellent platform to help the understanding of intrinsic properties of materials. This understanding is fundamental for the design of devices showing better performance. My work on the characterization of these outstanding quality materials has allowed me to have a great impact on the field.”

Since becoming an Emerging Investigator, how do you feel your research has developed over time?

“Since becoming an Emerging Investigator, I reinforced my research lines, while collaborating in fruitful projects lead by other excellent scientists. I am very happy how my career has evolved after being highlighted as Emerging Investigator.”

What are some of the current trends or emerging areas of research within your field that you find particularly exciting or promising?

“Few years ago, I started to see works reporting on ferroelectric hafnia. These results were mainly reported by people from Namlab in Germany. I thought at that time that the material was very promising. I thought that the ferroelectric properties were excellent, plus the important fact that the material was fully CMOS compatible. However, the mechanisms that determined the ferroelectric performance of the material were not completely accurate or reliable. Indeed, this issue is still not solved. I find exciting to work on the fundamental understanding of this material, which is extremely relevant to solve the bottlenecks that the material is facing in order to be implemented in commercial devices. I am also very excited by the fact that ferroelectric hafnia is one of the few examples where you have a lot of transversal work in parallel: from theory or fundamental understanding of the material (as me) to integration in commercial devices by many companies and start-ups. Thus, I think that ferroelectric hafnia is a promising material for new generation of energy efficient memory applications capable to be integrated in novel computing architectures and thus of the highest interest.”

What advice would you give to aspiring scientists who hope to make a significant impact in their respective fields?

“The important thing is to work and to think. Both are important. On one hand, you can have excellent ideas, but if you do not have the skills and you do not dedicate time to implement them at a minimum level, it is very unlikely that you will make your ideas understandable by the other scientists and therefore their potential impact can be severely affected. On the other hand, you can work a lot, but if you do not have in your mind clear questions to be answered, you and your colleagues time-investments can be useless. In addition, I also want to emphasize that you must be extremely rigorous and honest. Successful careers are made of a long list of results that others can reproduce and eventually to integrate on applications, or at least this is what I want to think.”

What are some of the main challenges or obstacles you have encountered while conducting your research, and how have you overcome them?

“I am very lucky. I have been working with excellent people. Maybe, this is one of the most positive aspects of my career. My collaborators are excellent scientists in addition of easy-going people. This is an important aspect of the role, science is mainly based on people, not on instruments, or materials, so it is very important to select the right people to work with. Dark side of my career is the bureaucracy. I am not an against bureaucracy. I fully understand that big portion of the research that I am doing is thanks to public funding, including my salary, and we must be extremely transparent and rigorous with all the actions that we take and the money that we invest. However, I find myself dedicating 1 or 2 hours per day to fill paperwork or to reply to people from administration, who, by the way, do an excellent work and I want to thank them for this. I would try to go for longer projects, with even more evaluation stages, and a much more rigorous evaluation of the scientific output. I think that institutions should also trust in the honesty of scientists. This would help a lot on reducing bureaucracy.”

What inspired you to pursue a career in your specific field of research?

“I would say my footsteps in my current research in nanomaterials and sensors were derived from my interest in chemistry. I have been getting quite good scores in Chemistry since middle school. It is amazing that you can create new materials and beautiful structures by chemical reactions, the process of which is quite magic and artistical. When I started pursing my postgraduate degree, I decided to follow my interest in chemistry to make new materials and structures and use them to fabricate gas sensors. To me, the sensory process is another field full of curiosity. The unseen interactions between gasses molecules and materials surface lead to visible changes in electrical signals. At the same time, I note the sensors are very ubiquitous and useful in our daily life. Although there are still many challenges, I would not stop my steps in this field.”

Since becoming an Emerging Investigator, how do you feel your research has developed over time?

“I would like to truly thank the editors of Materials Horizons for having considered me as a candidate for an Emerging Investigator. This further strengthens our confidence in the sensor research. It also helps build our credit in this field. In the past two years, we have received several invitations by RSC journals like Mater Horizon, Chem Comm, Chem Soc Rev and Sensor Diagnosis to submit our new works. I believe it is the quality of our works that lead to the invitations for submission. I also received a certificate as a RSC-Highly Cited Author. Looking back, since my first paper published in JMC in 2010, I have published over 15 papers in RSC journals. I would thank RSC for having contributed to the development of my career. I am more than happy that our works are read and recognized by the community.”
