Just sharing with you friends a very interesting research article led by my friend and co-worker, Professor Yanwen Zhang, on the role of electronic energy loss in HEAs. We also do very nice comparison with ceramics! Online now at Current Opinion in Solid State and Materials Science, Elsevier! https://www.sciencedirect.com/science/article/pii/S1359028622000213
Sharing my new seminar slides with the community on the challenges to design and evaluate new materials for extraterrestrial applications! This research has been only possible via an international collaboration with the brilliant metallurgy minds present at the Montanuniversität Leoben! Super interesting new works coming very very soon! Available at the ResearchGate! (LA-UR-22-23107) https://www.researchgate.net/publication/359771021_The_solar_system_as_a_new_frontier_for_materials_at_extremes
Dear Friends! We would like to wish you an excellent 2022 start with great accomplishments in life and research! This year starts a great promise with the commission of the James Webb space telescope, which holds the future of astronomy and astrophysics! With the beginning of the new year, we will resume the Nuclear Materials … Continue reading Nuclear Materials Highlights – Issue #2

A modified version of the well-known Cantor's alloy, the nanocrystalline CoCrCuFeNi high-entropy alloy was subjected to heavy-ion irradiation in situ within a TEM in our most recent study within the field of potential new nuclear materials. The stability of the alloy was investigated in a broad range of irradiation doses and temperature, revealing the nucleation … Continue reading Discovery of FeCo nanomagnets under irradiation in a high-entropy alloy
Read now our recent paper on #Space #Materials! Technology of #aluminium #alloys support human aspirations to conquer the space! Great #collaboration between @HudCompEng @HuddersfieldUni @ETH_en @unileoben @metallurgie_mul Nice cover by @AdvSciNews https://tinyurl.com/SpaceMaterials
Nanomaterials are offering unique opportunities for the design of future nuclear materials. In our recent paper at ACS Applied Nano Materials, we demonstrate that AISI-316 steel nanoparticles are capable of self-healing from the deleterious effect of heavy-ion collisions. We also pose a new question to the materials community on the recyclability of potential nuclear nanomaterials. … Continue reading Controlling radiation damage in nanomaterials
In two recent papers, we evaluate the application of the austenitic stainless steel AISI-348 in nuclear reactors. By using advanced electron microscopy techniques, it was found that the austenite phase can be quite unstable in energetic particle environments. Two very good works, don't miss reading them! =]
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)
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?
