Analysis of the Thermoelastic Damping Effect in Electrostatically Actuated MEMS Resonators
Mathematics, 2020 An important aspect that must be considered when designing micro-electro-mechanical systems (MEMS) for all domains, including robotics, is the thermoelastic damping which occurs when the MEMS material is subjected to cyclic stress.

Abnormal enhancement to the quality factors of carbon nanotube via defects engineering
Nano Materials Science, 2022 Low quality (Q) factor is often the limiting factor for high performance carbon nanotube (CNT) resonators. The most commonly used approach to enhance the Q factor of CNTs is to reduce/eliminate the intrinsic defects.
