The discovery of new materials is an immense challenge, with a vast design space and numerous success criteria. Microsoft has recently demonstrated an advanced approach to machine learning-assisted material discovery, particularly in the realm of lithium-ion battery electrolytes. They began by exploring all possible structure types, decorating these structures with various atoms, leading to a pool of millions of candidate materials. The screening process went beyond simple stability checks to encompass a broad range of criteria, including predicted properties, electrode stability, and cost. This was achieved through various layers of filtering, leveraging data from diverse calculations, ranging from costly DFT and MD simulations to lower-fidelity calculations. Microsoft wisely positioned the expensive calculations towards the end of the pipeline, focusing resources only on the most promising candidates. Furthermore, they partnered with the Pacific Northwest National Laboratory (PNNL) to synthesize the compounds identified. In this podcast, we'll delve into this process, the challenges faced, and the future opportunities in this field, in conversation with Chi Chen and Nathan Baker. If you want more details on teh work microsoft is doing in this space, you can check out their paper where they provide more details on the methodology and experimental results.

The challenge of plastic pollution in our environment will be a defining issue in the coming decades. To address this problem, scientists have developed a host of next generation biodegradable plastics that have the potential to improve the sustainability of single use products. Among these are a class of materials called PHAs which are of particular interest as their microorganism origins are also the means of their decomposition. Join us for a discussion with Nick Sandland as we explore the fascinating world of biodegradable polymers and what the future of plastics will look like.

Examining the inside of a material is often a destructive process that risks obscuring or deforming critical details. However, advances in computed tomography have opened new opportunities to obtain high resolution, three-dimensional reconstructions of materials in a non-destructive manner. Through this technique materials scientists can now identify cracks and voids in materials without the need for mounting and polishing, observe processes like battery degradation and dendrite growth in real time, and even obtain 3D diffraction data for identifying phase distributions in a material. In covering this fascinating topic, we are joined by William Harris from Zeiss Microscopy who shares his expertise as he walks us through the many ways computed tomography is reshaping materials science.
