Ultralight and ultra-stiff nano-cardboard panels: mechanical analysis, characterization, and design principles
Jong-hyoung Kim, Lishuai Jin, Benjamin C. Schafer +4
We introduce a class of ultra-light and ultra-stiff sandwich panels designed for use in photophoretic levitation applications and investigate their mechanical behavior using both c…
Analytical models for the design of photophoretically levitating macroscopic sensors in the stratosphere
Benjamin C. Schafer, Jong-hyoung Kim, Joost J. Vlassak +1
Photophoretic forces could levitate thin 10 centimeter-scale structures in Earth's stratosphere indefinitely. We develop analytical models of the thermal transpiration force on a b…
Ion-Beam Radiation-Induced Eshelby Transformations: The Mean and Variance in Hydrostatic and Shear Residual Stresses
Yongchao Chen, Qing-Jie Li, Alex O'Brien +5
Ion beam plays a pivotal role in ion implantations and the fabrication of nanostructures. However, there lacks a quantitative model to describe the residual stresses associated wit…
