Farewell to Professor Peter Hirsch — A Giant in Metallurgy and a Gentle Soul

~ Matheus A. Tunes ~ Leave a comment

The passing of Sir Peter Hirsch on September 12th 2025, marks the end of an extraordinary chapter in the story of metallurgy and materials science. Professor Hirsch, who escaped Nazi Germany as a child through the Kindertransport, went on to redefine how we see the inner world of metals. His pioneering use of transmission electron … Continue reading Farewell to Professor Peter Hirsch — A Giant in Metallurgy and a Gentle Soul

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?

Unveiling the Science of Nanometallurgy

~ Matheus A. Tunes ~ Leave a comment

A significant study from our research team, titled "Unravelling Nanometallurgy with In Situ Transmission Electron Microscopy: A Case Study with Copper Nanowires," was recently published in Nano Today. Led by Diego Coradini, our former PhD student, the research delves into the behavior of copper nanowires under extreme heating conditions within a transmission electron microscope. By … Continue reading Unveiling the Science of Nanometallurgy
