- Frequency-dependent stability of parallel-plate electrostatic actuators in conductive fluidsSounart, T. L.; Panchawagh, H. V.; Mahajan, R. L. (AIP Publishing, 2010-05)We present an electromechanical stability analysis of passivated parallel-plate electrostatic actuators in conductive dielectric media and show that the pull-in instability can be eliminated by tuning the applied frequency below a design-dependent stability limit. A partial instability region is also obtained, where the actuator jumps from the pull-in displacement to another stable position within the gap. The results predict that the stability limit is always greater than the critical actuation frequency, and therefore any device that is feasible to actuate in a conductive fluid can be operated with stability over the full range of motion.

- Laser-induced exfoliation of amorphous carbon layer on an individual multiwall carbon nanotubeSingh, G.; Rice, P.; Hurst, K. E.; Lehman, John H.; Mahajan, R. L. (AIP Publishing, 2007-07)Pulsed laser treatment of an individual multiwall carbon nanotube induced selective exfoliation of the amorphous carbon contamination layer. The multiwall carbon nanotube (MWCNT) was exposed to a 248 nm excimer laser. After the treatment, transmission electron microscopy images show that the amorphous layer has expanded and separated from the crystalline MWCNT walls. This interesting observation has implications for laser cleaning and possible thinning of MWCNTs to reduce the radial dimensions. (C) 2007 American Institute of Physics.
