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. Research led by @DrPhilEd and now at Materials&Design: https://sciencedirect.com/science/article/pii/S0264127521002264?dgcid=raven_sd_aip_email
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.

Serving as principal scientist of the Strategic Defense Initiative (SDI) project (aka Star Wars), Dr. Gerold Yonas was a pioneer scientist within the field of Materials at Extremes with a career which started at NASA's JPL and ended at the Sandia National Laboratories. With an impressive collection of scientific works in national security engineering, physicist … Continue reading Shooting high-power lasers through the stars!
Astonishing images from the Red Planet, sent back to us by the NASA's Perseverance probe! What a great moment in science! Mars and its extreme environment it is, of course, a materials at extremes challenge. Coming back to this soon! NASA has set-up a website to share images from the rover Perseverance: https://mars.nasa.gov/mars2020/multimedia/images/
In another great collaboration with Oak Ridge National Laboratory and Universities of Huddersfield, Leoben and São Paulo, we have investigated in depth the radiation response of a FeCrMnNi high-entropy alloy (HEA) compared with a commercial austenitic stainless steel. Yes, the HEA outperforms the steel by a 80% margin when thermodynamic stability of the matrix phase … Continue reading High-entropy alloys are indeed radiation resistant. What about the high-entropy?
