Designing Future Technologies with Gallium
Here’s a piece of element trivia: Gallium’s existence was first predicted by Dmitri Mendeleev in 1871, but it was not discovered spectroscopically until 1875 by Lecoq de Boisbaudran.
Thermal Contact Resistance Simulation
When 2 materials are in direct contact, thermal conductivity is determined by their properties, but surface roughness introduces air-filled gaps between the materials. How do you model this?
