Techologies & Solutions
Our technologies and commercialization strategy are based on carbon nanotubes (CNTs). We demonstrated a feasible method for fabrication advanced electrodes based on CNTs. Applications include cold field emission cathodes as efficient electron sources and anodes for gas ionization applications.

Currently, our CNT electrode ultracapitors are being developed through funding by Si Valley Ventures Capitalist firms (Khosla Ventures and Harris & Harris). The spin-off company, Ultora Inc., is in the process of commercializing carbon nanotube ultracapacitors based on the fundamental research and development of 4Wind Science and Engineering.
We have fully demonstrated a patent pending process for making carbon nanotube electrodes on metal substrates that have better interfacial contacts for low electrical resistance and mechanical stability. More importantly, the electrode fabrication process is inherently scalable for efficient manufacturing. Our patent portfolio includes fabrication processes for CNT electrodes and applications utilizing these CNT electrodes.
4WindSE has been awarded several SBIR grants and contracts for developing our CNT electrodes in a number of applications:
