Pro-Active Functional Materials- that utilize natural energy- that inhale carbon dioxide and exhale oxygen- that are capable of self-healing- that are capable of sensing, monitoring,

and responding- that are capable of recognition and self-

replication

Responsible Research Feed Science and Engineering Science and Engineering Lead to Innovations Innovations Propel the Economic Development

Why Materials Are Becoming Essential in Innovations?

When new scientific developments offer transformativeoutcomes with innovative solutions..what does this mean?

When materials offer a unique array of attributes neveroffered before

When creative engineering takes advantage of materialscapable of responsive

Self-healing plastic

This plastic, which bleeds red then heals itself with light, is being hailedas the Holy Grail of materials. The plastic could be developed for use in

self-healing cars, planes and bridges. Oh, and gadgets. RIP insurance?

Synchronized Heterogeneity

Preserved by replacing outdated components

Approaches: Stealth Materials; no interactions, no signaling

Degradable Materials; degrade, but typically arenot durability; no self-healing
