Understanding Energy Absorption Behaviors of Nanoporous Materials

Abstract : With the support of ARO through Grant No. W911 NF-04-1-0244, the energy absorption behaviors of nanoporous materials are being investigated systematically. The significant achievements include: (1) validating the concept of the use of nanoporous materials in energy absorption systems; (2) identifying the optimum surface species; (3) performed preliminary high-strain-rate experiment; (4) developed systems based on viscous liquids such as glycerin, so that the beneficial internal friction effect and shear thickening effect can be maximized; (5) identified suitable nanoporous materials; (6) analyzed energy generation associated with infiltration of ionic liquids; (7) applied the NMF liquids in honeycomb structures; (8) analyzed the direct compression of nanoporous frameworks; and (9) developed models to better understand the behaviors of pressurized nanofluids.
