In this episode of the Material Minds podcast, host Shrikrishnan Sankaran welcomes Marcus Koch, Head of the Physical Analytics Core Facility at INM, to discuss the power of advanced analytical techniques in materials science. Marcus shares captivating stories about using electron microscopy and X-ray spectroscopy to study a wide range of unusual samples—from ancient paintings and medieval artifacts to pizza baking and drinking water. Throughout the conversation, Marcus unpacks the intricate science behind these methods, shedding light on how they help us understand the degradation of historical objects, the mysteries of calcite in blue water, and even the behaviour of food at a microscopic level. Tune in for a fun and fascinating exploration of how cutting-edge technology meets the everyday world.
