TL;DR

Introducing architecture into material design enables lightweight yet strong materials with diverse applications.

Transcript

you so I'd like to begin by showing you this tetrahedron I guess now instead of a triangle that we like to use a material science between processing performance properties and structure and that is if you synthesize a material in a certain way you process it it inevitably will have certain structure it'll have certain properties and that will drive...
