Ionic Conduction
#31
01/04/2021

Diffusion is when atoms move through a material in response to a concentration gradient. However, some ions can move through a material in response to an electric field and can do so very quickly! Even more remarkable, the motion of ions can be restricted to ions of a certain type such as O2-, H+, Na+, Li+ etc. What is required of a material in order for it to be an ionic conductor? What technologies do ionic conductors make possible? Why are they necessary for batteries, fuel cells, sensors, electrolyzer, and more? We answer these questions and dive into...

Recycling and the Science of Separation
#12
12/02/2019

About half of the solid wastes produced each year end up in a landfill. A quarter gets recycled, 10% is composted, and the rest is burned. Why isn't more being recycled? Is this trend going to change? What will be the impact of China's new policy regarding impurities? This episode dives into recycling and we interview Dr. James Nagel of EDX Magnetics, a company with an innovative new tool for separating metals that could transform the recycling landscape.

Seeing With Electrons
#10
10/07/2019

The optical microscope was discovered in the 17th century and ever since has been a staple of scientific discovery. It uncovered germs and let humanity investigate the microscopic world. However, optical microscopes face a limit to their resolution since they rely on visible light. If materials scientists were going to ever probe atoms, grains, domains, and other features smaller than a few hundred nanometers, it would be necessary to fundamentally change the way we see matter.

In this episode we talk about electron microsopes. Their history, how they work, and some of the incredible advantages and features...


Materials That Remember
#9
09/02/2019

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.

Solving Structures with X-Rays
#5
05/06/2019

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...


Turning Heat into Electricity
#4
03/31/2019

In this episode we talk about thermoelectrics which, as the name suggests, 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 do...


Making Materials in a Microwave
#3
03/04/2019

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 mi...
