Coatings, thin films and advanced surfaces are important aspects of systems, devices and technologies critical to the mission of the Department of Defense. Despite decades of work, methods that enable atomic through millimeter-scale control over structure and properties of materials deposited on surfaces are still underdeveloped. For example, structural organization of high-value thin films is typically controlled by high-temperature deposition or annealing, but the temperatures employed during thin-film synthesis and deposition exceed the limits of many DoD-relevant substrates, restricting application opportunities.
Synthetic chemistry is important across countless technological areas, from medicines to energetics to advanced coatings to functional materials. While our synthetic capabilities have developed rapidly over the last century, current approaches are still slow and inefficient, with poor reproducibility and scalability and limited use of prior knowledge. Such an approach not only limits production of known materials, but also impedes discovery of better synthetic routes and completely new molecules.
The Molecular Informatics program brings together a collaborative interdisciplinary community to explore completely new approaches to store and process information with molecules. Chemistry offers an untapped, rich palette of molecular diversity that may yield a vast design space to enable dense data representations and highly versatile computing concepts outside of traditional digital, logic-based approaches.
The U.S. Department of Defense (DoD) develops and uses molecules and materials across a diverse range of areas including therapeutics, electronics, coatings, and fuels. Application areas with particularly unique relevance to national security, such as energetics, tend not to keep pace with the need for innovation and new performance characteristics.
The SIGMA+ program aims to expand SIGMA’s advance capability to detect illicit radioactive and nuclear materials by developing new sensors and networks that would alert authorities to chemical, biological, and explosives threats as well.
