A quirky podcast from Imperial College (Institute for Molecular Science and Engineering), that explore how tiny molecules matter in making big differences to global challenges.
Ep34: Sustainable Materials: Prof Joao Cabral, Prof Alamgir Karim & Dr Pedro Nakasu
Let’s define the problem.
Is there a plastic iceberg in the ocean? No, of course not. Micro plastics are invisible. And it’s going up the food chain. Why is there no solution for complex plastics (like nappies and crisp packets)?
How can we make multifunctional materials with smart polymers for solving grand challenges?
Join host Professor Joao Cabral (Chemical Engineering, Imperial), Professor Alamgir Karim (Chemical Engineering at University of Houston) and Post Doc Researcher Dr. Pedro Nakasu (Imperial) as they discuss the complexity of the life cycle of polymers (plastics) and how it affects the drive towards sustainable waste solutions.

Episode 33. SERCH Part 2: A Display Case for SERCH
In this episode we ask experts in Conservation and Conservation Research about the challenges they face in preserving our history, and why heritage conservation is important in today's times. Do we need more science and engineering researchers in the field of conservation? How is their work impacted by climate change?
This episode is part of our SERCH series (Science and Engineering Research for Cultural Heritage). For more episodes, please look at our episode list.
