Ceramics are known to amorphise under energetic particle irradiation. We show Cr2AlC MAX phase -- even in its non-pure semi-crystalline form -- can resist to amorphisation when in its grain-size falls into the nanocrystalline regime (10-100 nm)!

An important work by Arregui-Mena et al. demonstrating the manisfestation of cracks in nuclear grade graphite and how to characterise them using transmission electron microscopy. Free access over 50 days! https://doi.org/10.1016/j.matdes.2021.109673
A masterpiece from Sacha Distel. It is such a pleasure to discover and study new things. La belle vie! https://www.youtube.com/watch?v=YylZoZmfwRQ
How #nanocrystalline #materials are a potential class of #nuclear #materials? We show that a non-pure Cr-based MAX phase has high radiation resistance. Collab. between @HuddersfieldUni@HudCompEng@unileoben@metallurgie_mul Now at @ScienceAdvances https://bit.ly/3f8JzQc
Interesting paper on the effects of neutron irradiation in graphite materials. Great work by Dr Arregui-Mena @ORNL, collaboration with University of Manchester and Montanuniversitaet Leoben.

Ludwig Boltzmann versus the "stuck-in-the-mud" Viennese academy I am reading this marvelous piece of work by Professor David Lindley on the life and work of Ludwig Boltzmann. The biography of Ludwig Boltzmann is a topic that all scientists should pay attention on. Boltzmann was a scientist way ahead of its time, but what I did … Continue reading A history of personal struggle that changed Physics
The vastness and the beauty of the universe one day will come to an end. Worthwhile to spend 30 minutes of your life to watch this marvelous video from @MelodySheep: https://www.youtube.com/watch?v=uD4izuDMUQA
This is from my archives (2013), I found this beautiful piece of video showing Zircaloy-4 being cut in a Lathe and firing up at the Polytechnic School of University of São Paulo, the place where I proudly did my master in metallurgy with focus in nuclear engineering and nuclear materials under Professor C.G. Schön! Beautiful … Continue reading This is Zircaloy-4: the material that revolutionized the nuclear industry.
Important thoughts about "high-entropy" alloys...
The mystery of ’Oumuamua, the first interstellar object ever observed, continues to deepen. A new analysis argues that if it were a comet, it would have broken apart as it passed near the sun.
