Latest Patents

Xiaowei Li holds a patent for "Hydrogen gas sensors based on nanoparticle-decorated, patterned carbon nanotube ropes." This invention describes the use of nanoparticle-decorated carbon nanotube ropes as sensing elements for hydrogen gas chemiresistors. The sensors are prepared by dielectrophoretic deposition of a single semiconducting carbon nanotube rope, followed by the electrodeposition of metal nanoparticles. This method allows for a highly dispersed arrangement of nanoparticles on the carbon nanotube surfaces. The resulting rope sensors exhibit a relative resistance change that is 20-30 times larger than that observed with single, pure palladium nanowires. Consequently, these sensors improve upon all hydrogen sensing metrics, including speed, dynamic range, and limit-of-detection.
