Never Lick the Spoon

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.   Host Professor Joao Cabral - Professor of Soft Matter, Department of Chemical Engineering at Imperial Joao's links: https://profiles.imperial.ac.uk/j.cabral [https://profiles.imperial.ac.uk/j.cabral]   Guests * Prof Alamgir Karim - Dow Chair and Welch Foundation Professor Director, International Polymer & Soft Matter Center (IPSMC) Alamgir's links: https://www.chee.uh.edu/faculty/karim [https://www.chee.uh.edu/faculty/karim] * Dr. Pedro Nakasu - Research Associate, Department of Chemical Engineering at Imperial Pedro's links: https://profiles.imperial.ac.uk/p.souza-nakasu17 [https://profiles.imperial.ac.uk/p.souza-nakasu17]   Topics Discusses in this episode; * Different types of Polymers and their relationship to waste.  * Challenge in separation processes for recycling.  * Upcycling polymers instead of recycling.   * Fast Fashion and the degradation of fibres.  * Complex plastics (composites) that are difficult to recycle.  * Machines of the Futures to assist with sorting plastic.  * Role of consumers (Cost vs Performance)  * Process of diffusion.    * Smart use of plastics in healthcare.  * Sustainable plastics trending.  * Need for Systems Thinking and transdisciplinary collaborations.    Produced by Annemarie van Basten https://www.linkedin.com/in/annemarie-van-basten [https://www.linkedin.com/in/annemarie-van-basten]   Additional Links Imperial Department of Chemical Engineering link - https://www.imperial.ac.uk/chemical-engineering/ [https://www.imperial.ac.uk/chemical-engineering/]   Karim Research Group link - https://karimlab.chee.uh.edu/ [https://karimlab.chee.uh.edu/]   Article: Mapping the Chemical Complexity of Plastics link: Mapping the chemical complexity of plastics | Nature [https://www.nature.com/articles/s41586-025-09184-8]   Article: 'Your brain is full of microplastics: are they harming you?' link - Your brain is full of microplastics: are they harming you?

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).

The time has come to make new year resolutions! How about starting a collaboration with a researcher in a different field? Or expanding research beyond the lab into industry applications and policy recommendations? If these ideas have crossed your mind, then your new resolution could be to take a transdisciplinary approach.  At IMSE's annual research showcase, [https://www.imperial.ac.uk/news/256333/institute-molecular-science-engineering-imse-research/] we spoke to academics, journal editors and industry stakeholders to understand what transdisciplinary means and how they are using this approach to solve grand challenges. Have a listen at the diverse projects!

If you had access to a 3D printer, what would you print? Something fun, something useful? How about both? Alex Christopherson, a final year undergraduate student in Mechanical Engineering at Imperial College London and David Samuel [https://david-samuel.co.uk/category/sculpture/], an artist based in Park Royal Design Studios, collaborated to create a 3D printed sculpture that doubles as a microscope and allows you to see a 3D printed Queens Tower 100,000 times smaller than the real one! Engineering and art coming together to 3D print a sculpture. In this episode, we talk to both Alex and David. They discussed the design and production of the sculpture and how an engineer and an artist communicated throughout the project.
