Materialism: A Materials Science Podcast

Imagine stepping on your favorite glasses and bending the frame horribly out of shape. Now imagine immersing these glasses in boiling water and seeing them snap back into their original shape with no evidence of ever being deformed. Shape memory alloys are as close to real-life science fiction materials as it gets! In this episode, we dive into what the materials are, their discovery, how they work, and lots of cool applications.

Did you know that chocolate has a crystal structure? We all think of metals, ceramics, polymers, electronic materials, composites and so forth as materials. But what else? Is chocolate an engineering material? In this episode we dive into this amazing substance and describe the critical processing steps that makes it a unique including regional differences in cocoa, chocolate tempering and more. Along the way we'll cover the fundamental materials science topic of crystallization and solidification.

Can you structure a company like a material? In this episode we cover the fascinating discovery of Gore-Tex, and the equally fascinating company that created it. First, we delve in the materials science that allows Gore-Tex to repel water, while remaining breathable. We then, discuss the unique, non-hierarchical structure of W.L. Gore and Associates that has allowed them to continuously innovate over the past 60 years.

What role do materials play in artificial organs? Are there materials that body simply won't accept? In this episode we talk about the birth of artificial organs as we describe the history of hemodialysis which is critical for treating chronic kidney disease. We introduce materials science fundamentals associated with mass transport across semi-permeable membranes such as Ficks First Law. We then tell the story of Willem Kolff and others who pioneered the invention of hemodialysis and describe the role that materials played in that process then as well as now.

In this episode we cover the history and development of crystallography, the study of the structures that make up the materials around us. The history of this field is filled with accidental discoveries, ingenious inventions, and drama between those who study it. One of the most important discoveries to come out of this field is x-ray diffraction. This important characterization technique allowed scientists to delve deeper into crystal structures than ever before. We discuss new advances in x-ray diffraction with Ben Frandsen, an assistant professor of physics at Brigham Young University. Ben utilizes x-ray and neutron diffraction techniques to study super conductors and magnets.

We only scratch the surface of the fascinating history of crystallography in this episode. If you want to learn even more, check out Nature's Milestones in Crystallography.

In this episode we talk about thermoelectrics, which are materials that can convert heat into electricity or vice versa. Since their inception almost 200 years ago there have been major advances in thermoelectric efficiency and they have found their way into some amazing applications such as NASA’s deep space probes or the Mars rover Curiosity.

For the latter half of the 20th century, thermoelectric materials research was relatively stagnant with little improvement in materials. However, in the last two decades there has been a resurgence of interest in these materials and efficiencies have doubled. For this episode we talk about these recent advances with Paul Slusser who founded Power Practical, a company that commercialized a camping stove with a built-in thermoelectric generator. We describe some of the techniques that have been employed to create this efficiency gains and ask whether or not these materials are likely to make it out of the laboratory and into the market.

In this episode we learn about an unexpected approach to processing materials: the common kitchen microwave. While most people only think about the microwave when it’s time to reheat some leftovers, there has been a surprising scientific interest from materials researchers in the last few decades. In fact, microwave processing can achieve pretty remarkable feats such as extremely rapid sintering and heat treatment of materials as well as providing a means for microstructural control in alloys. There have even been cases where people have used it to weld and join materials together. In this episode we explain how microwave heating works in the first place, some of the past successes with this technique and we interview Dr. Christina Birkel who uses this as a critical component to her lab dedicated to the synthesis of novel new materials.

Welcome to the inaugural episode of the Materialism Podcast! In this episode we cover the most ubiquitous and important engineering material of all time: steel. The story of steel is fascinating and ties into the history of the Industrial Revolution, the birth of capitalism, and so much more. It would be hard to think of another material that did more to change society.
