Design Principles

"Amorphous structures can offer unique performance advantages over crystalline counterparts by enabling tailored electronic and chemical properties through controlled disorder."

Understanding how amorphous structures influence material properties through computational modelling allows designers to predict and optimize performance before physical prototyping.
