This Small Business Innovation Research project is to demonstrate large scale capability for sorting single walled carbon nanotubes by diameter and electronic type. Sorting of carbon nanotubes can lead to improved performance in existing applications as well as opening up new applications that… More

This Small Business Innovation Research Phase I Project will evaluate a method to produce large quantities of single-walled carbon nanotubes that are monodisperse in their diameter and/or electronic type (semiconducting or metallic). Availability of large quantities of monodisperse SWCNTs by size… More

In this Phase I project and the corresponding Phase I Option, we will investigate the feasibility of utilizing density gradient ultracentrifugation (DGU) for the production of large quantities of high-purity, semiconducting single-walled carbon nanotubes with a narrow diameter distribution (1.3-1.7… More

In this Phase II effort, we will scale-up to commercial levels a proprietary technology for producing highly semiconducting enriched (99%) single-walled carbon nanotubes (SWNTs). The technology utilizes a technique, called density gradient ultracentrifugation (DGU), to separate as-grown SNWTs by… More

This Small Business Innovation Research (SBIR) Phase I project aims to develop a diameter refined semiconducting single walled carbon nanotubes (SWCNTs) to address the challenge of bandgap heterogeneity in semiconducting SWNTs. The plan is to utilize the latest advances in SWNT separation including… More
