Nanotechnology

Nano-particles (NP) are particles and materials that have one or more size in the nano-meter regime. One of the most well known are Carbon Nanotubes (CNT) which are cylindrical shaped hollow tubes made of rolled carbon sheets with high aspect ratios. Those particles posses superior electrical, mechanical, and thermal material properties. Several techniques have been developed to synthesize, manufacture, and apply NPs in daily applications to benefit from the material property aspect of it.

At IR4TD the research is directed toward:

Nano-materials possess unique thermal, mechanical and electrical properties unlike their macro-structured counterparts. The IR4TD has expanded the basic knowledge of pure and mixed nano-materials to create and satisfy next generation engineering applications. Included is the enhancement of nan-material functionality for:

  1. Selective heating;
  2. Weight reduction; and
  3. Heat propagation.

Such knowledge and experience can be used for industrial and medical applications

Carbon Nanotubes (CNT) cylindrical shaped hollow tubes made of rolled carbon sheets with high length to diameter ratio and possess super electrical, mechanical, and thermal material properties. Carbon nano-tubes were synthesized first around 1985, and their structure was defined around 1991. CNTs are categorized to Single Wall Carbon Nanotubes (SWCNT) and Multiple Wall Carbon Nanotubes (MWCNT). Several techniques have been developed to synthesize CNT.

At IR4TD two methods of synthesis are researched, flame based methods and Chemical Vapor Deposition (CVD). Flame has been fruitfully applied to the synthesis of carbon nanostructures. IR4TD researchers use the coflow methane diffusion flames and counterflow diffusion flames to synthesize CNTs in curved and entangled forms as well as well-aligned paralleled and uniform sized forms according to the catalyst substrates used. The average diameter of synthesized CNTs is 60 nm. The synthesized CNTs effects of carbon sources, temperature, and catalyst were experimentally and numerically analyzed. CVD methods have been optimized using experimental and computational applications.
