In our fourth episode of “STEMTalk With STEMEncounters,” we look at the publication regarding Metallic Nanocrystals with Low Angle Grain Boundary for Controllable Plastic Reversibility. The paper discusses that if we harness a material condition, we can allow for materials, specifically metallic nanocrystals, to be recycled repeatedly, quickly, and efficiently. We discuss what grain boundaries are and what this publication aims to do with them. Then, we dive into what the publication concept would mean if applied to the real world.

We then dive into our second publication about Magnetic Field-Assisted High-capacity Durable Li-ion Battery using Magnetic α-Fe2O3 Nanoparticles Decorated Expired Drug Derived N-doped Carbon Anode. We discuss the publication, what the magnetic field allows for the Li-ion (Lithium-ion) battery, and what the drug derived N-doped carbon anode allows for the battery while learning new concepts like ferromagnetism and X-Ray Diffraction. Then, we discuss our recent blog post on if Li-ion based batteries are viable or are Na-ion (Sodium-ion) batteries better relating to the topics in the publication and what each battery if appropriately applied, would mean for the world.
