Carbon nanotube growth on metallic substrate using vapor phase catalyst delivery

Carbon nanotubes (CNT) have captured the attention of materials scientists and technologists due to their unique one-dimensional structure by virtue of which they acquire superior electrical, mechanical, and chemical properties. Current methods for CNT growth on substrates have their drawbacks. Vertically aligned CNT growth on metallic substrates requires catalyst islands on the substrate, which limits its ultimate application. Aligned CNT growth is a complicated, multi-step process and requires a brittle substrate, such as indium tin oxide.

Super-compressible carbon nanotube films and micro-bundles

Structural foams have a variety of applications, such as cushioning, packaging, and construction. Compressive strength and compressibility are important factors to determine the performance and application of foams. However, since these factors are of opposing nature there is a need for structural foam with high compressive strength, compressibility, and resilience. This invention is comprised of on open-cell carbon nanotube which exhibits super-compressible foamlike behavior. They have higher compressive strength, recovery rate, sag factor, and breathability.


Multi-walled carbon nanotubes have been produced by several different methods, including chemical vapor deposition and laser ablation. These nanotubes are either grown as a layer of aligned nanotubes or as intertwined, randomly oriented bundles of nanotubes. Carbon nanotubes have many potential applications due to their mechanical, electrical, and eletronic properties. However, the difficulty in asembling the nanotubes into desired complex architectures and patterns hinder some applications. This invention is directed to a carbon nanotube foam.

Embedded Nanotube Array Sensor ENTAS

Routine, nondestructive inspectsions of aircraft components take place at periodic intervals before and during operation of an aircarft to ensure safety of flight. These mandated inspections focus on damage caused by impact, flight induced stress, or manufacturing defect. Currently, most of these inspections are time consuming, expensive, and result in significant downtime of the aircraft. This invention is directed to nanosensors that can detect structural change in aircraft components.
