We are excited to share findings from our latest research on the potential use of MAX phases in nuclear reactors. MAX phases, known for their hexagonal-compact nanolayered crystal structure, high machinability, and chemical inertness, have long been considered promising materials for nuclear applications. However, our new paper sheds light on crucial aspects that must be … Continue reading Exploring the Stability of Ti-based MAX Phases in Extreme Nuclear Environments

Novel high entropy ceramics for extreme environments
We investigate the radiation response of a hard refractory high entropy carbide (HEC): the (CrNbTaTiW)C. Comparison with the high entropy alloy (HEA) has shown the HEC outperforms the HEA under irradiation. Results suggest high-entropy ceramics can be alternative to HEAs in extreme environments. Available now at Acta Materialia (open access)! Do not forget to see … Continue reading Novel high entropy ceramics for extreme environments
A decade probing the radiation response of Ti-based MAX phases
Can Ti-based MAX phases -- this new class of potential functional materials -- be applied in future nuclear reactors? We investigated the response of Ti-based MAX phases to both neutrons and heavy ions. The discoveries of this intense decade-long research has just been published at Materials Today Energy. Open access article access here: https://doi.org/10.1016/j.mtener.2022.101186

The message of my PhD Thesis in one picture
As you well know, my PhD thesis is now online for public consulting. It took me a lot of time to get this thesis (gooosh!) in a good shape and I am very proud of the final result. I hope you guys also enjoy the reading. This afternoon I was thinking about a picture within … Continue reading The message of my PhD Thesis in one picture
External Events: how safe a nuclear reactor can be?
The development of nuclear technology has allowed unprecedented progress for mankind. Modern medicine could not be the same without the numerous diagnosis protocols involving the application of concepts and products directly (and indirectly) derived from nuclear engineering. On nuclear reactors, it is unquestionably how cost-competitive, clean, environmentally-friendly and powerful electricity can be generated by using … Continue reading External Events: how safe a nuclear reactor can be?
Ceramic coatings for Accident Tolerant Fuels (ATF): the case of titanium nitride (TiN)
Our first scientific paper on ceramic coatings for ATFs systems is finally published (in press) at the Journal of Nuclear Materials and it can be downloaded in this link. The paper addresses on the radiation tolerance of nanocrystalline magnetron-sputtered titanium nitride thin films. The coatings were subjected to medium energy heavy-ion irradiation at the homologous … Continue reading Ceramic coatings for Accident Tolerant Fuels (ATF): the case of titanium nitride (TiN)
Are TiN coatings appropriate candidates for accident tolerant fuels?
I am so delighted to announce that our paper "Energetic particle irradiation study of TiN coatings: are these films appropriate for accident tolerant fuels?" has just been accepted for publication at the Journal of Nuclear Materials! In this study, we have used heavy ion irradiation in situ within a Transmission Electron Microscopy to investigate whether Titanium Nitride … Continue reading Are TiN coatings appropriate candidates for accident tolerant fuels?
