Never Lick the Spoon

Episode 30. Sculpting with 3D printing

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.

Episode 29 - Happy Women in Engineering Day from IMSE

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.

Episode 28 - Fine art and floppy discs

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.

Episode 27 - Robots built my battery

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. 

Episode 26 - The ingredients list

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.

Episode 25 - In plane sight

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.

We also refer to the 2023 Royal Society policy briefing in the podcast. 

Episode 24 - Desirably defective

Silicon-based solar panels are four times as efficient as plants at harvesting energy from sunlight. But they're expensive to produce because the material they're made of has to be very precisely engineered. What if we could make solar panels out of copper oxides, where the imperfections in the material are what makes them effective? I talk to two researchers who used a supercomputer to discover this.

Episode 23 - The Trojan Molecule

Molecules that change shape when light falls on them have many uses. Like the Trojan Horse, they can look benign, but transform into a weapon under the right circumstances. This week we explore how photoswitchable molecules could help tackle the next pandemic.

Episode 22 - Crystal healing

This month, we're focusing on a chemical process which is all around us: how crystals form. Humans have been using crystallisation to harvest salt from seawater for millennia. In the modern industrial world, it's used to make sugar, gemstones and silicon chips. So it’s a bit of a surprise to find a completely undiscovered phenomenon, of a crystal healing itself, happening in crystals of paracetamol. How have we missed this? Why is it happening? And how could it be useful? 

Episode 21 - Soilless soil

One way of increasing food production is to develop substitutes for soil which can be used to grow plants. Why is 3D printing a good way of doing this? And how could it be used make new non-Earth type soils for farming in space?
