Nanocomposites of MXenes and other 2D materials is our main research topic currently, since they will bring new physical properties and a large tuning window which are not possible in the single composition. During the last few years, our team has developed various nanocomposites with tunable electrical, optical, and electrocatalytical  properties. Our main focus is enhance their processibility for large scale manufactural and commercialization, thus robustness, e.g., colloidal stability, chemical stability, reproducibility of these nanocomposites are very important aspects.

We have developed this topic in collaboration with the University of Oulu since 2020. Together with Dr. Hosseini Shokouh and Prof. Kordas, we have unveiled the potential of MXene-polymer composite for ultra-sensitive and selective gas sensors. MXene as a metallic 2D material provides extraordinary signal-to-noise ration for the sensors. From the promising results, we have filed our IPR and now pushing this technology to commercialization.

In MNC, we are very interested in studying the dynamics and structures of various soft matters, including functional nanoparticles, hydrogels, MXene nanocomposites, thin film devices, etc. Most of the experiments were performed on synchrotron X-ray beamlines, where the high-flux and focus beam enable us to understand the system with higher time and special resolution. Here, we apply beamtime with our collaborators to solve problems and acquire data that is not possible from in-house facilities.

Zhongpeng Lyu is one of the responsible lecturers of E0527 in PHYS since 2022, together with Ville Liljeström. This course is aimed at doctoral students and MSc students at Aalto and does not require advanced studies in Physics. The course introduces the basics of elastic X-ray scattering methods, and during dedicated lectures/demonstrations, the focus is on a few conventional, frequently applied methods that are available at Aalto University. Teaching/learning activities include lectures, hands-on demonstrations, and project work. Our course also invites X-ray experts from other departments of Aalto and other universities in Finland. 

MSC group has established research collaborations in Finland, Germany, Sweden, Spain, US and China. If you are interested in discussion or collaboration of relevant research topics, please email zhongpeng.lyu@aalto.fi or other group members.

We are currently opening a summer job position, and we are looking for a motivated and passionate student with a background in material science, chemistry, or a similar field, and some understanding of RF electronics. The key task is to formulate 2D material nanocomposite coatings for broadband electromagnetic absorption across the GHz–THz range, and test their performance in minimizing the external noise of superconducting quantum processors.
