Nanotechnology Research and Education
Tennessee, located in the Southeastern United States. It covers a total area of 109,247 km2 and has a population of 6,456,243 as of 2012.
Tennessee's 2011 GDP was reported to be $266.5 billion by the Bureau of Economic Analysis. Manufacturing and healthcare are the two largest non-government contributors to the local economy. The key manufacturing exports include electrical equipment, chemicals and transportation equipment.
Reasons to locate a new business in Tennessee include good location, low cost of doing business, high quality work force and no personal income tax.
A brief introduction to the key nanotechnology-related organization in Tennessee is given below:
Tennessee Nanotech Alliance: Focuses identifying the emerging opportunities and addressing the challenges of nanotechnology all over the state of Tennessee. This organization aims at educating people from all walks of life on the fundamentals of nanotechnology by promoting various research activities in universities, research centers, laboratories and industries.
The chief nanotechnology-related company in Tennessee is given below along with a brief introduction:
eSpin Technologies: eSpin Technologies, Inc. was founded with the mission to develop the technology to commercially manufacture nanofibers and nanofiber-based products.
Functioning as a self-funded Advanced Research Facility, eSpin has teamed up with several Federal Agencies and Industrial Partners to develop unique solutions for filtration and environmental remediation, functional textiles, and advanced materials. eSpin works with its Partners to enhance existing, as well as develop new-to-the world products by customized application of nanofibers to meet the current and future needs of the customer.

There is no doubt that ORNL is a world leading lab that is at the forefront of most technologies including nanotechnology. Some of their recent developments include:
- Researchers at the Oak Ridge National Laboratory and the University of Tennessee have demonstrated that ion current can be increased by DNA translocation through a carbon nanotube. These researchers used molecular dynamics simulations to prove that large electro-osmotic flow can be turned into a large net ionic current through an ion-selective filtering process by a DNA molecule inside the carbon nanotube.
- Using and electron microscope, researchers documented the dancing motion of silicon atoms in a graphene sheet
- ORNL researchers have developed the first high performance, nanostructured solid electrolyte for more energy dense lithium ion batteries. Such batteries could also overcome problems with existing Li-ion batteries that relate to safety issues with the flammability of their liquid electrolytes.
- Using theoretical and experimental studies, researchers are beginning to understand and control the self-assembly of insulating barium zirconium oxide nanodots and nanorods within barium-copper-oxide superconducting films. These developments have implications on a range of electronic devices.
Recent developments at the University of Tennessee are as follows:
- Assistant Professor Jaan Mannik secured $650,000 over 5 years to investigate basic cellular functions which could lead to micro- and nano-engineered chips for live cell imaging.
- They have recently installed two of the most powerful microscopes in the world, (the Auriga and Libra from Zeiss worth $3.5 million) that are also able to be remotely operated. These microscopes allow imaging at the atomic level and cutting and slicing at the nanoscale.
- Nanoparticles from a micro-orgaqnism have been captured and could be used to treat cancer
High quality research from ORNL will continue to flow helping to develop the understanding of all things nano. Some of these developments will have commercial and industrial impacts in the neat term. Meanwhile, researchers at the University of Tennessee will need to justify the capital expenditure on their new microscopes. This factor, along with the previously unavailable capabilities will also mean that developments should flow from researchers there as well.
This all means that Tennessee should become a nanotechnology hot spot that should be monitored for new developments.
