Copyright, 1988

I visited Symposium OO and heard a talk on "Possible Degradation Mechanism of Zirconia Ceramic under Bio-medical Conditions" by Yoshimura. He started off the talk by stating that one of his most important papers was published in 1988, the year I was born! Since then he has expanded his work, but that paper from twenty years ago, "Phase Stability of Zirconia," is the groundwork for all of his later research.The talk was interesting because it is focused on when zirconia breaks down, and it explains how degradation occurs using fundamental knowledge.

Fun fact: Zirconia is used as material for "teeth screws"
