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

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?

Radiation shielding for nuclear-fission powered human-based Mars missions

As multinational space programs progress towards establishing permanent human settlements beyond Earth, radiation shielding and damage continue to pose significant challenges. A fascinating recent paper discussing radiation shielding in the context of future nuclear-fission-powered Mars missions has been published in Nuclear Science and Technology Open Research. Bendoyro AC, Thomas LD, Cassibry J and Emrich W. … Continue reading Radiation shielding for nuclear-fission powered human-based Mars missions
