Advanced Materials


ORNL has the nation’s most comprehensive materials research program and is a world leader in research that supports the development of advanced materials for energy generation, storage, and use. We have core strengths in three main areas: materials synthesis, characterization, and theory. In other words, we discover and make new materials, we study their structure, dynamics and functionality, and we use computation to understand and predict how they will behave in various applications.

From its beginnings in World War II’s Manhattan Project, ORNL has had a distinctive materials science program. Today, materials science research benefits from ORNL’s integration of basic and applied research programs and strong ties among computational science, chemical science, nuclear science and technology, neutron science, engineering, and national security. This broad approach to research is allowing ORNL to develop a variety of new materials for energy applications and transfer these new materials to industry. For example, an understanding of how defects form at the atomic level allows creation of improved materials that approach their theoretical strength, such as radiation-resistant steels for next-generation nuclear reactors and lightweight materials for energy-efficient transportation. In electrical energy storage, we are studying how chemical processes occur at the interface of electrodes and electrolytes and using supercomputers to predict how battery systems will perform. We develop “soft” materials, including polymers and carbon-based materials, used as membranes for batteries, fuel cells, and carbon capture, solar cells, and as precursors for the carbon fiber used in lighter cars and planes. We’ve also discovered ways to improve materials processing, using photon, microwave and magnetic field-assisted processing to increase the performance of new materials while reducing processing costs.   These advances have resulted in a broad portfolio of ORNL materials and technologies in the nuclear, automotive, and structural materials industry.

ORNL researchers are improving analytical tools used to characterize the structure and function of advanced materials, including electron microscopy, scanning probes, chemical imaging, and a variety of neutron scattering capabilities. Many of these capabilities are available through DOE user programs at ORNL, including the two neutron user facilities (the Spallation Neutron Source and the High Flux Isotope Reactor), the Center for Nanophase Materials Sciences, and our microscopy user facility (the Shared Research Equipment User Facility—which will be incorporated in the CNMS later this year). Complementing our experimental research is one of the nation’s largest collections of materials theorists who take full advantage of ORNL’s leadership computational facility to understand and design new materials, as well as processes that occur at materials interfaces. Together, these research capabilities in materials synthesis, characterization, and theory contribute to our leadership in basic and applied materials science that ultimately will lead to new technologies for meeting tomorrow’s energy needs.

Predictive calculations of cuprate magnetic properties
— Magnetic couplings in a realistic cuprate system have been correctly predicted for the first time with highly accurate Quantum Monte Carlo (QMC) calculations. Effective magnetic models of superconductivity (previously reliant on experiment) can now be derived with confidence from theory, which could lead to better fundamental predictions of superconductor behavior.

Cooperative Growth of Large Single-Crystal Graphene Islands
— Researchers showed that it is possible to grow large, single-crystal graphene islands by controlling the nucleation density, which determines the growth mechanism.

Polar ordering induced by oxygen vacancies
— A combination of scanning transmission electron microscopy (STEM), electron energy loss spectroscopy (EELS) and density functional theory (DFT) calculations show that it is possible to achieve polar order in a superlattice made up of two non-polar oxides by means of oxygen vacancy ordering.
