AMRL is working on advancing multiscale science and computational tools for design, synthesis and scale-up of advanced materials. We focus our physics-based modeling on the design and scale-up of polymers, catalysts, battery materials, coatings, composites, molecular crystals, 2D materials for conductive ink, and alloys for energy and environmental applications.
- Mesoscale and Multiphysics Modeling: Connection of atomic scale averages to the mesoscale using coarse-grained, discrete element, fluid dynamics, and finite element models; multiphysics models of materials processing and manufacturing

Creating high performance materials
As articulated in a recent DOE report “The ability to predict and control mesoscale phenomena and architectures is essential if atomic and molecular knowledge is to blossom into the next generation of technology opportunities, societal benefits, and scientific advances”. The challenge of modeling phenomena in the mesoscale is scaling the system size and the physics to the boundaries of nano-and-microscale where continuum behaviors emerge. Due to recent advances in precision in 3D printing, mesoscale assembly of materials through proper control of transport, reactions, and phase segregation processes are possible. However, there remain large gaps in understanding mesoscale. The outcome of the research at AMRL is an ability to predict Structure-Property-Performance-and-Processing (SPPP) correlations in complex mesoscale architectures under dynamic thermo-chemo-mechanical conditions and bridge fundamental science constructs to the engineering scale.
