Exploring Biomaterials for Better Coatings

In this video, Prof. Yeau-Ren Jeng from the National Chung Cheng University talks about studying enamel, the top layer of the tooth. The reason for his choice of biomaterial is the ideal combination of hardness and toughness of the enamel. Usually, a hard material will be brittle. He was curious to know how Mother Nature could make such a material out of a very brittle mineral. He wants to adapt his learning to create better engineering materials that are lightweight, long-lasting, and have excellent wear resistance.

The team integrated the Bruker Raman system into this indentation system, which allows them to co-rotate it. For areas affected by stress, strain, or temperature, they could observe how the thermo effects of loading any energy input into the material would change its mechanical properties and tribological behaviors. With this insight, which was not available before, better coatings, fabrication tools, or for magnetic decoder for hard disks for many data storage systems can be made.
