We would like to thank the award committee for selecting two winners from a large number of exceptional candidates, one of them being Dr. Roberta De Robbio. We will continue to reward scholars with the Travel Award to express our acknowledgment of their support for our journal. We wish them every success in their careers.

The following is a short interview with Dr. Roberta De Robbio:

1. Can you briefly introduce yourself to our readers and tell us a little bit about your fields of interest?

I graduated in Mechanical Engineering for Energy and Environment in 2016 and defended my Ph.D. thesis in 2020 at the University of Naples Federico II. After two years at the Institute of Sciences and Technologies for Sustainable Energy and Mobility of the National Research Council, I am currently a post-doctoral researcher at University Federico II, and recently, I won the selection as a researcher (type A) at the same University.

The main topic of the research activity is combustion analysis and modeling by means of computational fluid dynamics (CFD) tools. To this end, I have conducted parallel studies on two different types of thermal plants, say: a micro gas turbine fueled with biofuels and hydrogen, and diesel engines supplied with natural gas and hydrogen in dual fuel mode. I have tested, implemented, and utilized several models and kinetic mechanisms in different codes. Each process, such as turbulence, injection, vaporization, and oxidation, has been examined with the aim to evaluate pollutants’ emissions and to reduce their formation.

2. Which research topics do you think will be of particular interest to the research community in the coming years?

I think the climate change emergency, environment preservation and all the related issues will still be central topics in the next years. Indeed, it is a problem that affects everyone and all sectors of the economy. In addition, clean energy from renewable sources is the object of my studies, and I am doing my best to give my contribution, not only as a researcher.

3. Can you briefly describe the key to a happy laboratory life?

I believe that the key to a happy laboratory life is respect and communication between the members of the staff. I believe that to achieve the desired goals in a team, everyone should cooperate, and when a difficulty is encountered, they should not be afraid to ask for help.

4. What is your opinion of the open access model of publishing?

In my opinion, open access publishing can be a fundamental tool to spread knowledge not only among researchers, but also among students and people who are employed or simply interested in a determined field. It also offers the chance to be informed of the latest findings to the researchers of institutions with low financial possibilities, mitigating the gap in education levels in the international scientific community.

5. As the winner of this award, is there something you would like to express?

We had the pleasure of interviewing Prof. Dr. Maria Founti, Section Editor-in-Chief of Energies (ISSN: 1996-1073), to discuss her recent research activities in the field and her views on women in the engineering field. We hope all women enjoy this International Women’s Day.

Name: Prof. Dr. Maria Founti
Affiliation: School of Mechanical Engineering, National Technical University of Athens
Research Interests: combustion; fire engineering; energy efficiency in buildings; LCA; KPIs

 Prof. Dr. Maria Founti was born in Piraeus in 1955. She has been a faculty member at the School of Mechanical Engineering of NTUA since 1987. She has been the Director of the Laboratory of Heterogeneous Mixtures and Combustion Systems since 2002 and Professor in the Thermal Engineering Section since 2007. She holds a B.Sc. degree in nuclear engineering from the University of London, an M.Sc. and D.I.C. in heat transfer engineering and a Ph.D. (1983) in combustion technology from Imperial College London. She has worked as a research associate at the Chair of Fluid Mechanics of the University of Erlangen-Nuremberg, Germany (1983-1987).

Her current interests focus on energy saving and storage in buildings combined with advanced energy systems and materials, combustion systems and processes and heterogeneous mixtures, fire engineering and compartment fires, multicriteria assessment and life cycle analysis for the techno-economic, social and environmental impacts of energy systems.

She has 250 publications in international journals and conferences. She has participated in and coordinated 40 funded research projects. Prof. Dr. Founti was a member and chair of the E.C.'s External Advisory Board (1998-2006) for FP5 and FP6 for research on materials, products and production processes.

She has served as chairman of the Examination Committee of Building Energy Inspectors (2012-2014). She speaks English, German, French and elementary Portuguese.

The following is an interview with Prof. Dr. Maria Founti:

1. Could you please tell us a bit about yourself?

I have been a mechanical engineer for nearly 40 years. In the late 70s, mechanical engineering was considered a hard topic, especially for women. I was educated in England, and I have work experience in England, Germany, France, and Portugal in the 70s and 80s.

My expertise is in combustion, a field that combines knowledge from very different phenomena and disciplines, from very basic engineering to very advanced theoretical knowledge.

Combustion analyzes and optimizes the way fossil/biofuels burn and how we use the produced thermal energy in different energy systems. The energy transition and the decarbonization target that the EU and other countries have set create a framework for moving away from conventional combustion systems, such as boilers, furnaces and internal combustion engines. Nowadays, there are voices that believe that decarbonization will slowly eliminate the need for research in combustion, but I believe this will not happen. One reason is the fact that it will take another 30 to 40 years to complete the transition to energy systems that will operate without the need of transforming chemical energy from fuels into thermal energy. This includes all types of currently used energy systems in the industry, transport, and building sectors. Additionally, there are new generations of fuels based on synthesis processes exploiting renewable energy sources. Such fuels will have to be used during the transition period in the existing energy systems. The research in combustion will have to continue. The research focus may change, in terms of specific topics and themes, that will be elaborated in the future, but the conceptual and methodological tools will remain the same. For the academic circle, we will adapt to the new requirements. It will take a lot of time until we move away from traditional combustion in our everyday life.

2. Would you like to share something about your current research?

Our laboratory, the laboratory of Heterogenous Mixtures and Combustion Systems of the National Technical University of Athens, focuses on the investigation of energy production via thermo-chemical conversion, not only pure combustion. At the same time, we are working intensively on the techno-economic, environmental, and technical feasibility assessments of innovative energy systems and processes that are based on the concept of using chemical energy to regulate and control the production of thermal and electrical energy. The research combines the understanding of fundamental phenomena and processes with the impact assessment at system level. This multi-level and interdisciplinary approach is necessary to support the upscaling and market introduction of new energy systems.

We look also at the interface between the use of energy systems in buildings and building component performance—basically, the interaction between the envelope of the building and renewable energy systems. Last, but not least, we are also working on fire engineering, recognizing that the fire performance of building materials and building energy systems becomes increasingly important because of the use of new materials and related changes in construction. We have a horizontally organized lab with different groups working on different interlinked topics. This strongly promotes the collaborative spirit among the lab researchers. In a nutshell, the key topics are energy efficiency, especially in the building environment, coupled with fire safety issues, life cycle analysis, and techno-economic and environmental assessment.

3. What motivated you to join the Energies Editorial Board? How was your experience working with the journal editorial team?

I believe in Open Access. Why Energies and why MDPI? Because you are very active and consistent. You make every effort to keep the standard as high as possible. As I said before, I believe combustion has a future. If you look at the Special Issues and the papers published in Energies that are related to the broad topic of combustion, they are very interesting and they cover a lot of different topics.

I like the punctuality, the marketing approach, and last, but not least, the IT support of MDPI, which is very efficient and reliable. Maybe more personal contact, like the one that we are having now, would further improve the journal's quality. Getting to know the other editors, the Special Issue editors and how they see things, could broaden the range of thematic topics and the acceptance of the journal as a very high-quality open access means of publication.

4. How do you think COVID-19 affects engineering research projects and publishing?

I think the first year of the pandemic was positive for publishing because a lot of researchers were quarantined and stayed at home. They had more time to analyze previous research work and prepare articles for publication. In the second year, a decrease started showing, in terms of practical and experimental research due to the effects of COVID-19. This will be reflected in publishing; I think it has already started becoming apparent. It may show more in the next year. We will see more theoretical and computational work being published rather than experimental work, because of having limited access to experimental facilities and infrastructures. This affects, for instance, Ph.D. students, younger researchers, and their work.

5. As we know, the engineering field is male dominated. When you were young, what made you decide to become an expert engineer?

My first degree was in nuclear engineering in 1976. This somehow has affected my career. When I was young, 14 or 15, I was impressed by the biography and life of Marie Curie. Since then, I pictured myself in a lab doing research. That’s when I decided to study nuclear engineering. Always in my life, passion for what I am doing was a dominant factor in deciding what to do. I never questioned myself “why engineering?”.

Most importantly, I think we should point out that the percentage of women studying engineering increased gradually but continuously in the last twenty years. Therefore, perceptions change, and for the next generations of young women, engineering will not be considered a male-dominated profession. Women will not be skeptical any longer about entering the engineering profession. In the past, people believed that engineering was associated with manual work that could not be undertaken by women. However, the advent of IT diversifies the role of engineers, and women are much needed in this process.

I believe these messages are starting to be passed to the younger generations. Nevertheless, the percentage of women not practicing their engineering profession or dropping out is quite high, and this should be looked at.

In addition, from my experience in the academic environment, I cannot see any performance difference between men and women. There are pros and cons, strengths and weaknesses in both. Women are not lacking anything in their early career stages compared to men. There is a gap in the senior engineering management positions for women. The percentage of women that are entrepreneurs, in top management positions, CEOs, etc., is not that big. Often women compromise or adjust their careers to take care of their families, although this is also changing.

6. Would you like to give some advice or tips for other women who are pursuing or will pursue a career in this area?

Believe in yourself and follow your dreams. Do not compromise, set realistic goals, and try as hard as you can. The more you do, the more creative you feel.

7. Thanks for sharing. It’s also our great honor to collaborate with research experts and extraordinary female engineers around the world. Finally, do you have any suggestions for our journal’s future development?

Keep it up. Don’t fall into the trap of “mass low-quality publishing”. Keep on increasing the quality, visibility, and acceptance in the academic circle.

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.

Peer Review Week began 19 September 2022 under the theme of “Research Integrity: Creating and Supporting Trust in Research”. Through various blog articles, podcast, and webinar, we discussed this crucial subject throughout the week, celebrating the essential role peer review plays in maintaining research quality.

To begin, we held a Webinar on the topic. Professor Peter W. Choate and Dr. Emmanuel Obeng-Gyasi joined Dr. Ioana Craciun, one of MDPI’s scientific officers, for an in-depth discussion.

We invite you to view the event recording:

During the week, the MDPI Blog in a series articles highlighted how good Peer Review safeguards research integrity. The following topics were covered:

• Peer Review Week 2022
• Research Integrity
• What We’ve Learned About Peer Review Reports
• 4 Steps to the Perfect Peer Review Report
• How to Write the Perfect Peer Review Report: An Interview
• Inviting Great Peer Reviewers

In a new edition of Insight Faster, an MDPI podcast, we were delighted to talk to the co-chairs of the Peer Review Week committee, Jayashree Rajagopalan (Senior Manager of Global Community Engagement for CACTUS) and Danielle Padula (Head of Marketing and Community Development at Scholastica) to get their take on this year’s event and its related topics.

You can find the Podcast here.

We hope you enjoy the contents!

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

This program intends to provide an opportunity for early career scientists to enhance their editing, networking, and organizational skills and to work closely with our journal to gain more editorial experience. Early career scientists who have novel ideas for new Energies Special Issues will act as Guest Editors under the mentorship of an experienced scientist; this mentor could be a member of the Editorial Board of Energies (ISSN: 1996-1073), from other well-established research institutes or laboratories, etc.

The mentee’s responsibilities include:

• Providing a CV, including a list of publications;
• Proposing a Special Issue title and a short introduction;
• Writing a brief promotion plan for the Special Issue;
• Writing an editorial for the online Special Issue;
• Reviewing and making decisions for submissions under the mentorship of our Editorial Board Members.

The mentor’s responsibilities include:

• Conducting a final check before the Special Issue is published online;
• Co-editing the Special Issue with younger scholars and performing quality control of the publications in the Special Issue;
• Providing suggestions to younger scholars if they have doubts or concerns regarding submissions;
• Organizing video calls with young scholars and the office regularly to discuss problems and improvement suggestions for the Special Issue.

Certificates and awards:

When the Special Issue is closed, the Editorial Office will provide official certificates for all the mentors. The younger scholars will be prioritized as candidates for Energies Young Investigator Awards in future editions.

If you are interested in this opportunity, please send your Special Issue proposal to the Energies Editorial Office (energies@mdpi.com), and we will discuss the process (mentor collaboration, Special Issue topic feasibility analysis, etc.) in further detail.

In addition to the new Special Issue Mentor Program, Energies will continually welcome all Special Issue proposals based on hot research topics as usual.
