Design fabrication and calibration of MEMS actuators for in-situ materials testing
Many MEMS devices utilize thin metallic films as mechanical structures. The elastic and plastic properties of these thin films (thickness < 1μm) are significantly different from those of the bulk material. At these scales the volume fraction of material defects such as: grain boundaries, …

Mechanisms of focused ion beam (FIB) material removal and rearrangement at high beam flux
… (MD) simulations of nanopore fabrication in freestanding thin films. We focus on the root mechanisms as described by large-scale MD simulations of FIB and describe the role of explosive boiling and Marangoni effect as a material removal and rearrangement mechanism and the mixing and transport …

Polymeric Melodies: Polyetherimide Modification-Based Acoustic Membranes and Sonochemical Degradation of Polystyrene
… approach to enable the reinforcement of a thin film membrane via carbon nanotube embedding. In addition to the generation of nanocomposites, effective chemical recycling of waste plastics has become paramount to solving the current pollution crisis. While most see discarded plastic as waste …

Electromechanical response of textured ferroelectric PZT thin film stacks
Thin film piezoelectric materials with high piezoelectric coefficients such as PbZr0.52Ti0.48O3 (PZT) offer several advantages to microelectromechanical systems (MEMS) due to their low power requirements, large displacements, high work and power densities, as well as high sensitivity in a wide …
