The Engineered Metallic Nanostructures Laboratory (EMNL) focuses on understanding the design, synthesis, stability, and mechanical behavior of metallic nanostructures including monolithic nanocrystalline alloys, crystalline-amorphous nanolaminates, metallic glass matrix composites, and other unique hierarchical metallic structures. These novel materials are synthesized through electroforming, sputter and pulsed laser deposition, and additive spray manufacturing techniques. Experiments are used in concert with atomistic simulations to study thermal stability, radiation tolerance, and deformation behavior that results from competing mechanisms at the nanoscale. EMNL group members conduct research at   the Center for Functional Nanomaterials  and    NSLS-II  at Brookhaven National Laboratory,    the Advanced Energy Center  at Stony Brook University, and collaborate with    the Institute for Advanced Computational Science . EMNL is supported by the National Science Foundation through the Division of Materials Research and the Civil, Mechanical and Manufacturing Innovation Division, and Empire State Development’s Division of Science, Technology and Innovation (NYSTAR).
