What is the impact of materials research?Many of the technological advances that have transformed our world over the past 20 years have been founded on the developments of materials research. The benefits of these advances are evident in many of the products and technologies that have become so much a part of our everyday lives: our vehicles; the machines and efficient products in our homes, offices, and schools; the computers and phones we can’t live without; lifesaving medical technology; and much more. Materials research is focused both on discovering new materials as well as understanding how existing materials behave in new and enhanced products. Improved understanding enables us to better leverage the capabilities of known materials to make them safer, more convenient, efficient, cost-effective, and sustainable. This knowledge is critical to our continued growth in a competitive global economy and to addressing the 21st century’s grand challenges in energy, sustainability, health, security, mobility, communications, and other areas.
