Upscaling and Recycling of Aluminium Alloys

~ Matheus A. Tunes ~ Leave a comment

The demand for sustainable metal production is driving innovation in aluminium recycling. The new preprint of our group led by Dr. Sebastian Samberger is available and it is entitled Impurity-Induced Phase Transformations in AlMgZn(Cu) Crossover Alloys: Pathways to Enhance Recycling Content and Processability. Dr. Samberger explores how Fe/Si ratios and cooling rates influence phase transformations and … Continue reading Upscaling and Recycling of Aluminium Alloys

The last set of images taken by Voyager 1 spacecraft

~ Matheus A. Tunes ~ Leave a comment

A fascinating research paper recently caught my attention: it documents the final images captured by the Voyager 1 spacecraft before its cameras were permanently shut down. While the images themselves are breathtaking, what truly stood out to me was the incredible effort behind protecting the spacecraft from radiation damage as it ventured farther from the … Continue reading The last set of images taken by Voyager 1 spacecraft

A great scientific debate: Are clusters or Guinier-Preston zones responsible for strengthening an Al-Cu-Mg alloy?

~ Matheus A. Tunes ~ Leave a comment

Feature image credits: https://www.scienceisweird.com/arguing-comics Science thrives on debate, and the historic clash between Ringer et al. and Zahra et al. over the role of solute clustering in Al-Cu-Mg alloys is a perfect example of how scientific disputes drive progress. In this case, one side argued that Cu-Mg clusters were a distinct strengthening mechanism, while the … Continue reading A great scientific debate: Are clusters or Guinier-Preston zones responsible for strengthening an Al-Cu-Mg alloy?

Exploring the Future of Green Hydrogen and Sustainable Aviation Fuel in Brazil

~ Matheus A. Tunes ~ Leave a comment

In a recent interview with Estadão, I had the opportunity to discuss the promising role of green hydrogen in advancing sustainable practices within agriculture and industry. We explored the significant challenges associated with large-scale adoption, including the low volumetric energy density of hydrogen, the energy-intensive nature of its production, and the phenomenon of hydrogen embrittlement … Continue reading Exploring the Future of Green Hydrogen and Sustainable Aviation Fuel in Brazil
