“Low-Temperature, Highly Sensitive Ammonia Sensors Based on Nanostructured Copper Iodide Layers”
by Sergey I. Petrushenko, Mateusz Fijalkowski, Kinga Adach, Denis Fedonenko, Yevhenii M. Shepotko, Sergei V. Dukarov, Volodymyr M. Sukhov, Alina L. Khrypunova, and Natalja P. Klochko
Chemosensors 2025, 13(2), 29; https://doi.org/10.3390/chemosensors13020029

1. Could you please briefly introduce yourself to our readers and share your current research focus, including any recent developments in your work?
First, I would like to thank the editorial team for the opportunity to introduce myself and my research group. Unfortunately, interest in the natural sciences is not a top priority these days, and Ukrainian scientists in such fields have virtually no platforms to engage with a wider audience.
Currently, I lead two research groups engaged in diverse scientific activities. The first group focuses primarily on fundamental research on low-dimensional systems. We investigate how the various properties of films, particles, or polycrystals change as they transition to the nanoscale. Working within the phenomenological thermodynamic paradigm, we aim to develop a comprehensive scientific picture. We seek to bring together completely different fundamental phenomena and provide a unified description of them. At present, our group is investigating the thermal expansion of nano-objects, which is expected to yield highly unique results in this field.
The second part of our research group (within the framework of which this article was published) conducts applied research in sensor technology and thermoelectrics. In this area, we also work with nanostructures, but we produce them using simple and scalable chemical synthesis methods. The samples obtained are not suitable for fundamental research. However, they enable us to solve a wide range of applied problems, including detecting low concentrations of ammonia at room temperature. As part of this research, we are developing neuromorphic interfaces. Such structures can, on the one hand, be used to develop new methods of information processing and, on the other hand, to enable new sensor mechanisms.

2. Could you briefly introduce the key research focus and main findings of this paper?
This article focuses on the development of chemical sensors, particularly ammonia sensors. I don’t want to repeat the article's text here, but I would like to point out that ammonia is an important industrial compound and is also of biogenic origin. This allows ammonia to serve as a marker for therapeutic conditions and necessitates monitoring its levels at industrial sites.
Conventional ammonia sensors require heating, which limits their application. We have, however, proposed a simple and effective method for detecting ammonia that operates at room temperature. The sensor film does not require heating, is extremely compact, and can operate with a relatively simple measurement circuit.

3. Looking ahead, what impact do you hope your research will have on the field, and what do you consider to be the most significant innovation presented in your paper?
Our research is already advancing in this field. Having identified chemical sensitivity in chemically deposited CuI films, we have begun fundamental investigations of vacuum-deposited samples. To date, we have observed that many of the diverse sensing properties of thin films (for both gaseous analytes and electromagnetic radiation) are likely attributable to oxygen-mediated mechanisms. We hope to confirm our hypotheses regarding the latter. This will enable us to formulate a comprehensive scientific picture that describes various sensitivity mechanisms within a general paradigm.

4. Could you share some of the major challenges in your research area, as well as any recent breakthroughs that you find particularly exciting?
Our field of research is not one traditionally associated with paradigm-shifting breakthroughs. We do not work with ultra-high-energy accelerators, cannot peer into the first moments of the Universe, and do not develop new theoretical concepts capable of radically transforming our understanding of the world around us.
That aside, our work is no less important, for it is precisely this kind of research that ensures steady scientific progress, whose cumulative effect periodically leads to fundamental breakthroughs. The most significant advances in our fundamental research are expected to come from extending studies of size effects to the mechanical properties of nanostructures. In terms of applications, I see the greatest potential in developing neuromorphic interfaces, which, with sufficient miniaturization, could yield genuine breakthroughs in information processing, comparable to the emergence of large language models.

5. Do you have any advice for young researchers who aspire to produce high-impact research results?
To be honest, I consider myself a fairly young researcher, so I’m not sure I’m in a position to offer advice. Still, in my view, the most important tip for young scientists to keep in mind is to be prepared for the realities of science.
Real science isn’t about a genius scientist in his garage. It isn’t about daily breakthroughs, publications in Nature (the world's top multidisciplinary science journal), or interviews with leading outlets. It’s about a multitude of failed experiments, a pile of baffling results, and harsh words that carry little meaning yet a powerful emotional charge.
Real science involves constantly writing proposals, reports, reports on reports, and yet more reports. It also involves finding equipment when none is available or finding ways to obtain results by pushing the available equipment to its limits. Real science is about results that often seem more than modest. Getting them published in a reputable journal often requires as much effort as obtaining them in the first place.
But at the same time, real science is also about the freedom you’ll never find in any other job. It’s that sense of being part of something globally vital, of being the one who truly broadens horizons. It is the opportunity to keep moving forward, to learn and develop—in other words, to do everything that sets young people apart from older people. And it is precisely because of this that, by seriously immersing yourself in science, you will be able to remain young for a long, long time, avoiding the descent into old age.
And of course, I’d like to encourage young researchers never to give up, even if you suddenly find yourself in a foreign country.  Without knowing a single foreign language (to avoid this, learn English from childhood, not as some people do), with just one bag, one laptop (which you grabbed from friends at the last minute and need to return as soon as possible), and one USB stick, you can certainly get back to your favorite activity if you don’t give up, even if it seems there’s no chance. And if you’re lucky. But remember that luck merely multiplies your efforts; it doesn’t create them.

Our portfolio of journals available for publishing up-to-date research in immediate open access format has been further expanded. In June 2026, eleven new journals released their inaugural issues and two transferred journals released their first issue as part of MDPI, covering the subjects of environmental & earth sciences, chemistry & materials science, public health & healthcare, engineering, medicine & pharmacology, and biology & life sciences. 

We extend our gratitude to the Editors-in-Chief, Associate Editors, and Editorial Board Members who will shape the future course of these new journals. Each journal is dedicated to upholding strong editorial standards through a thorough peer review process, enabling impactful open access scholarship. 

Please feel free to browse and discover more about the new journals below.
