Telemedical Retinal Image Analysis and Diagnosis (TRIAD)

Submitted by ORNL, Automated Medical Diagnostics and the University of Tennessee Health Science Center. ORNL team members: Kenneth Tobin, Thomas Karnowski, Luca Giancardo, Deniz Aykac and Priya Govindasamy. UTHSC team members: Edward Chaum and Yaqin Lee

The TRIAD technology is a Web-based telemedical diagnostic system designed to conduct automated eye screenings of large patient populations for blinding diseases, such as diabetic retinopathy, in a primary health care setting. The real-time, low-cost screening provided by TRIAD assists primary care providers in offering a more efficient and economical retina screening service to prevent blindness in diabetic patients. The diagnostic tool will enable more people to undergo screening, especially the indigent and those in areas that are medically underserved. Research funding was provided by ORNL's Laboratory Directed Research and Development (LDRD) program, the Plough Foundation, Research to Prevent Blindness, the U.S. Health Resource Services Administration and the National Institutes of Health - National Eye Institute.

Liquid Microjunction Surface Sampling Probe for Mass Spectrometry

Submitted by ORNL and NextGen Services. ORNL team members: Gary Van Berkel and Vilmos Kertesz

The ambient surface sampling system for mass spectrometry uses a sampling probe for quick, efficient liquid extraction of analytes directly from surfaces. The system's ability to analyze materials outside a vacuum and under real-world conditions demonstrates a significant improvement over existing technologies, limited to surface sampling within a vacuum. The product's simplicity, speed and cost effectiveness make possible a range of uses within the biological sciences, including applications in pharmaceutical research and drug discovery. Research was funded by ORNL's LDRD program, the Department of Energy's (DOE) Office of Science, a CRADA with MDS Sciex, UT-Battelle's Privately Funded Technology Transfer Program and ORNL royalty maturation funding.

Sulfur-Carbon Nanocomposite Cathode Material and Additives for Lithium-Sulfur Batteries

Submitted by ORNL. Team members: Chengdu Liang and Nancy Dudney

The technology offers a more functional sulfur-carbon nanocomposite cathode and halide additives to the electrolyte to solve problems inherent in existing lithium-ion battery technology. Researchers hope the lithium-sulfur battery system can improve the energy density of current technologies by a factor of five. By enabling a more reliable, safer and longer lasting battery system, the invention has the potential to aid in the harnessing, storage and use of electricity from renewable energy sources. The project was funded by ORNL seed money and the DOE's Vehicle Technology program.

Ultrasensitive Nanomechanical Transducers Based on Nonlinear Resonance

Submitted by ORNL. Team members: Nickolay Lavrik and Panos Datskos

Based on nonlinear nanomechanical resonators, the technology enables sensitive linear detection of force or mass that can be used in a number of important applications, including chemical and biological detection, inertial navigation and thermal imaging. The technology can identify the presence of extremely low levels (femtogram quantities) of chemicals in a gas or liquid with a sensitivity 1,000 times greater than that of comparable mass-sensitive transducers on the market. The new method used in the nonlinear resonator transducers can provide real-time monitoring in a cost-effective manner and can lower detection thresholds in both gas and liquid environments, without increasing the cost and complexity of the tool. Research funding was provided through ORNL's LDRD program.

Strontium Iodide Scintillator for Gamma Ray Spectroscopy

Submitted by Lawrence Livermore National Laboratory and developed in conjunction with ORNL, Fisk University, Radiation Monitoring Devices Inc. and the Department of Homeland Security's Domestic Nuclear Detection Office. ORNL team members: Lynn Boatner, Joanne Ramey and James Kolopus

The technology allows for the precise detection of illicit sources of uranium, plutonium and other radioactive materials, which can play a critical role in identifying nuclear and radiological threats. Europium-doped strontium iodide enables the highestresolution gamma-ray spectroscopy for a scintillator detector to identify radionuclides. The technology's superior scintillator energy resolution and cost-effective production will prove invaluable for homeland security applications. Research was funded through the DHS Domestic Nuclear Detection Office.

High-Performance, High-Tc Superconducting Wires Enabled via Self-assembly of Non-superconducting Columnar Defects

Submitted by ORNL, SuperPower Inc., the University of Houston, and the University of Tennessee. ORNL team members: Amit Goyal, Sung-hun Wee, Eliot Specht, Yanfei Gao, Karren More, Claudia Cantoni, Keith Leonard, Malcolm Stocks, Tolga Aytug, Mariappan Paranthaman, David Christen, Jim Thompson and Dominic Lee.

The technology is a three-dimensional self-assembly process for the fabrication of ultrahigh-performance superconducting wires. The method is designed to create non-superconducting nanoscale columnar defects with nanoscale spacing within high-temperature superconducting wires. The desirable defects can improve the performance of high-temperature superconductors by enabling large currents to flow through the materials in the presence of high applied magnetic fields. The need for high-temperature superconductors in the electric power, medical, transportation, industrial and military sectors demonstrates the product's commercial viability. The research was funded through the DOE's Office of Electricity Delivery and Energy Reliability and ORNL's LDRD program.

Flexible, Large-area, Single-Crystal-like, Semiconductor Substrates

Submitted by ORNL and TexMat. ORNL researcher: Amit Goyal

The technology results in a large-area, flexible substrate with a single-crystal-like semiconductor surface. The process starts with a textured metal or alloy substrate upon which various multilayers are grown heteroepitaxially, leading to a semiconductor surface. Further epitaxial growth of device layers on such substrates is used to fabricate devices for electronic applications such as photovoltaics, displays, ferroelectrics, solid-state lighting, and assorted sensors. Such flexible substrates potentially can be made in sizes that are orders of magnitude greater than is currently possible with standard rigid semiconductor wafers. Research at ORNL was supported by a work-for-others project.
