About this Research Topic

Background

There is growing interest to leverage optical sensors and data science for nuclear materials analysis in many applications including radioisotope production, safeguards, forensics, security, and the nuclear fuel cycle. Characterizing nuclear materials by traditional methods is challenging due to extreme environments (radiological, temperature, chemical, etc.), specimen availability, and regulations. Optical spectroscopy techniques exhibit several characteristics that make them well-suited for standoff measurements and online monitoring applications. These advantages include rapid/real-time analysis, compatibility with chemical- and radiation-resistant materials, and sensitivity to many species and material properties. Optical techniques can be combined with data science methodologies and experimental design to efficiently account for sample complexity, various instrumental techniques, and the generation of large datasets. The deployment of these methods for the analysis of nuclear materials can improve safety, reduce operational costs, and minimize the consumption of valuable materials.

This Research Topic is dedicated to highlighting the latest advancements in optical sensor and data science development for cutting-edge fundamental and applied research. This collection intends to bring together forward-thinking experts from diverse disciplines to highlight recent advancements and identify future objectives. Rapid technological advancements in terms of instrumental techniques and data processing are being leveraged to provide the nuclear field with robust, rapid, and in situ measurements.

Topics within the scope of this collection include the identification of unique signatures, the development of new protocols and standards, the development of standoff measurements, the design of feedback tools for machine learning driven applications, the improvement of analysis time, the establishment of process control, and the engineering of deployable sensors for hazardous nuclear environments. Articles describing innovative studies, applications, perspectives, and concepts to advance the development and characterization of advanced nuclear materials with optical sensors and data science are welcome.

Topic themes of particular interest to this Research Topic include, but are not limited to, the following:
• Standoff, in situ analysis, and characterization of nuclear materials
• Production and optimization
• Online monitoring
• Sampling and experimental design
• Ensemble learning and sensor fusion
• Advanced data processing strategies
• Optical sensors as a feedback tool
• Forensics and nonproliferation applications
• Standards, guides, and best practices
• Unique signatures

All manuscript types are welcome in this Research Topic.

Frequently asked questions

  • Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

    Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

  • The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

    Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

  • As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

    A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

  • Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

  • Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

    As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

    Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

  • Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.

  • Yes, we would love to hear your ideas for a topic. Most of our Research Topics are community-led and suggested by researchers in the field. Our in-house editorial team will contact you to talk about your idea and whether you’d like to edit the topic. If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor.

  • A team of guest editors (called topic editors) lead their Research Topic. This editorial team oversees the entire process, from the initial topic proposal to calls for participation, the peer review, and final publications.

    The team may also include topic coordinators, who help the topic editors send calls for participation, liaise with topic editors on abstracts, and support contributing authors. In some cases, they can also be assigned as reviewers.

  • As a topic editor (TE), you will take the lead on all editorial decisions for the Research Topic, starting with defining its scope. This allows you to curate research around a topic that interests you, bring together different perspectives from leading researchers across different fields and shape the future of your field. 

    You will choose your team of co-editors, curate a list of potential authors, send calls for participation and oversee the peer review process, accepting or recommending rejection for each manuscript submitted.

  • As a topic editor, you're supported at every stage by our in-house team. You will be assigned a single point of contact to help you on both editorial and technical matters. Your topic is managed through our user-friendly online platform, and the peer review process is supported by our industry-first AI review assistant (AIRA).

  • If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor. This provides you with valuable editorial experience, improving your ability to critically evaluate research articles and enhancing your understanding of the quality standards and requirements for scientific publishing, as well as the opportunity to discover new research in your field, and expand your professional network.

  • Yes, certificates can be issued on request. We are happy to provide a certificate for your contribution to editing a successful Research Topic.

  • Research Topics thrive on collaboration and their multi-disciplinary approach around emerging, cutting-edge themes, attract leading researchers from all over the world.
