Episode notes
From Refugee To Chemistry Passion
- Admir Masic describes growing up in ex-Yugoslavia, becoming a refugee, and finding chemistry in Croatian high school.
- His refugee experience and mentorship from an encouraging psychologist and teachers propelled him into chemistry and later research.
Cement’s Disproportionate Climate Role
- Cement is the most-used material on Earth and drives ~8–13% of global CO2 emissions due to clinker production and kiln fuel.
- Small chemistry and process changes at scale can therefore yield outsized climate impact.
Longevity Trumps Peak Strength
- Roman concrete trades lower mechanical performance for exceptional longevity by self-healing microcracks.
- That longevity, not peak strength, is the key lever to reduce lifetime emissions from built infrastructure.
