On an atomic scale, the area of a material in which different crystalline structures come together is known as a grain boundary. In this video, LIAM HUBER investigates the behavior of alloying elements at grain boundaries. * Identifying impracticalities in quantum mechanical simulation, Huber uses classical simulation to study how atoms behave at the grain boundary and how this influences the properties of that grain boundary. Huber also employs machine learning to make predictions and to extend the insights provided by the study. Going forward the research will seek to further explain the influence of a range of variations including, most significantly, temperature. * This LT Publication is divided into the following chapters: 0:00 Question 1:50 Method 4:08 Findings 6:45 Relevance 8:34 Outlook
