Andrea Sella

Join Professor Andrea Sella, an inorganic chemistry expert from University College London, and fire investigation officer Matt Oakley as they ignite a spirited conversation about spontaneous combustion. Sella reveals how oily rags can spontaneously ignite, while Oakley shares alarming statistics on lithium battery fires and the potential dangers they pose. Discover the fascinating science behind self-heating materials and why certain everyday items can catch fire without a spark, plus the chilling debate on whether spontaneous human combustion is real.

Andrea Sella, a Professor of chemistry at University College London and an expert on rare-earth elements, discusses the unique electronic and magnetic properties of lanthanides. Tim Cross, The Economist's senior science writer, tackles the pressing geopolitical implications surrounding rare earths, especially China’s export controls. They explore the critical roles these elements play in technology, the challenges of recycling, and potential alternatives for Western industries. Could this be the wake-up call for a shift in global supply strategies?

Exploring historical poisonings with insights from a chemist and Agatha Christie fan. Discussing the ease of access to poisons, famous cases, and deadly garden plants. Delving into literary depictions of poisons in crime novels and the potency of cyanide. Analyzing thallium poisoning in Agatha Christie's 'The Pale Horse' and playful discussions on symbolic meanings of poison.

Chemists Andrea Sella and David Cole-Hamilton discuss the significance of the periodic table and the potential scarcity of elements in the future. They highlight the importance of making better use of resources. The podcast also explores the discovery of a significant helium reserve in Tanzania and the abundant supply of indium. Overall, it delves into the impact of elements on the modern economy.

Chemistry professor Andrea Sella joins the discussion on the various states of matter beyond solids, liquids, and gases, exploring plasma and exotic phases like glasses and liquid crystals. The podcast delves into the complexities of molecular structures, phase transitions, material evolution from pure elements to alloys like steel, and the impact of industrial revolution on material science.
