Tunable Mechanical Response of Self-Assembled Nanoparticle Superlattices by Dhulipala, Somayajulu, Yee, Daryl W., Zhou, Ziran, Sun, Rachel, Andrade, José E., Macfarlane, Robert J., Portela, Carlos M.

“…Here, we perform in situ nanomechanical experiments that evidence up to an 11-fold increase in stiffness (∼1.49 to 16.9 GPa) and a 5-fold increase in strength (∼88 to 426 MPa) because of surface stiffening/strengthening from shaping these nanomaterials via focused-ion-beam milling. To predict the mechanical properties of shaped NPSLs, we present discrete element method (DEM) simulations and an analytical core-shell model that capture the FIB-induced stiffening response. …”
