Further improving the corrosion resistance of Al-based alloys for aerospace applications with Cr-free treatments

~ Matheus A. Tunes ~ Leave a comment

A great paper and research led by my friend Oscar M. Prada Ramirez recently shows that the corrosion resistance of aerospace grade Al-based alloys can be significantly improved using Ce-nanoparticles in an anodization treatment using tartaric-sulfuric acid environments! The aluminium alloy series 2xxx with its anodic layer filled with Ce nanoparticles! A pathway to reduce … Continue reading Further improving the corrosion resistance of Al-based alloys for aerospace applications with Cr-free treatments

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

It is time to talk about toxic culture in academia and scientific research as well!

~ Matheus A. Tunes ~ Leave a comment

Just sharing a very nice article from MIT Sloan management review on toxic culture and its effects in workplace environments... I think it is time for us to talk about toxic culture in science and academia as well! https://sloanreview.mit.edu/article/why-every-leader-needs-to-worry-about-toxic-culture/ Twenty percent of employees have left a job because of its culture.iiReplacing an employee can cost … Continue reading It is time to talk about toxic culture in academia and scientific research as well!
