Computation Design>MORE materials and applications National Academy of Sciences(1995) The phrase"materials by design”(材料设计) Human Weifare Clean Energy Computational Tools with an increasingly theoretical component to the Experimental Digital design process,is becoming a reality.Researchers Tools Data are thus using theory and computation to "design" Materials Innovation Workforce Infrastructure materials. It has always been a dream of materials researchers to design a new material completely on paper,optimizing the composition and processing steps in order to achieve the ud No Lr properties required for a given application.

Computation + Design → MORE materials and applications National Academy of Sciences (1995) The phrase “materials by design”(材料设计) with an increasingly theoretical component to the design process, is becoming a reality. Researchers are thus using theory and computation to “design” materials
