Research Summary

Anastasios John Hart's research currently focuses on synthesis and applications of nanostructures such as carbon nanotubes, microsystems, machine design, and scientific visualizations.

Carbon nanotubes (CNTs) are cylindrical molecules of carbon atoms, where the carbon atoms are arranged in a hexagonal lattice as in graphite. Because carbon-carbon bonds are very stable and strong, and because CNTs are seamless and have a very small diameter (1-100 nanometers), CNTs have exceptional properties. High-quality CNTs have several times the strength of steel piano wire at one-fourth the density, at least five times the thermal conductivity of copper, and very high electrical conductivity and current-carrying capacity. These properties have generated broad interest in CNTs, for potential applications such as next-generation electronics where individual CNTs are device elements, to advanced composites where trillions of CNTs work together to form the structure of an airplane wing.

Hart's research with CNTs started with his doctoral work at MIT, where his Ph.D. thesis focused on creation of processes and instruments for atmospheric-pressure synthesis of CNT films on substrates.

    Manufacturing of metal components is essential to every major industry, consumes significant natural resources, and involves complex supply chains. The promise of a digital thread from alloy formulation to scaled production and potential re-use therefore has inspired new experimental approaches and manufacturing techniques that go hand-in-hand with computational methods. This talk will highlight MIT research in the “hands-on” side of metals processing—including high-throughput laboratory techniques, in situ characterization of deformation and microstructure, new additive manufacturing processes, and resource-efficient extraction. An outlook will be framed in terms of the value chains of key industries, pathways for commercialization, and business models enabled by digital transformation.
