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.

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.

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, 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, 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.

Women in Engineering day is celebrated on the 23rd of June. To commemorate this special date, we talked to two women in engineering working and studying with the Institute for Molecular Science and Engineering (IMSE). Our guests for this episode are electrochemist and co-director of the Molecular Engineering masters, Dr. Anna Hankin, and masters' student and representative of her cohort, Kawtar Houbad.

Listen to their stories on how they became engineers, their current projects, engineering skills outside of the lab - from fixing boilers to building steam engines at home - and learn about the power of mentoring.

What sorts of science and engineering challenges do museums have in looking after their collections? In this episode I explore how Imperial’s research into data science, polymers and lasers is being used to understand and preserve historical and archaeological objects.

In this episode my guests refer to two chests in the collections of the Victoria & Albert museum. The first is the Mazarin Chest with its Japanese lacquer surface. The results of the conservation of the lacquer have been published in Scientific Conservation. The second is a 17th century embroidered box. Vibrational modelling on this casket was carried out by Kerstin Kracht (Technical University of Berlin) to build a crate to allow this to be safely shipped overseas for display.

A team at Imperial are building a robotic laboratory called DIGIBAT. This will automate research into materials for energy storage and energy generation. Robots won't just discover new materials. They'll also do the laborious work of testing all the many combinations of those materials to find out which make the best batteries and fuel cells. 

What do fertilizer, body lotion, paracetamol tablets and mayonnaise have in common? Well, they’re all engineered mixtures, and they all have a long list of unpronounceable chemicals on the back of the packet. How can adjusting these chemicals affect the climate impact of the product? We dive deep into formulations.

What are the sustainable alternatives to kerosene to power aircraft into a net zero world? And what would it take to scale their production up to meet demand? I talk to two authors of the recent IMSE briefing paper on low carbon fuels for aviation. We talk energy, technology readiness levels and the need for multidisciplinarity.
