Thermal Transfer is a critical part of power electronics application in both terrestrial and space environments. Due to longer lifetime expectancies and harsh operational conditions, space vehicles require unique materials to deal with the increasing electrical and thermal loads placed upon the structure. Increasing use of power electronics including high current carrying semiconductor devices such as IGBTs, MOSFETs, power transistors, and modules drive the need for specialty thermal management materials both in the packaging of the discrete devices as well as for the packaging of modules consisting of several or arrays of these devices. The overall objective of this program (Phase II) is to adapt CarbAlTM-based advanced thermal management substrates from terrestrial to space applications. ANI will target improved CarbAl-based heatsinks and thermally conductive circuit boards for power electronic applications. CarbAl is a carbon-based thermal composite with a thermal performance exceeding that of many metals. The low CTE provides excellent matching to state-of-the-art power transistor dies and the low density and robustness make it suitable for space vehicle applications. The proposed Phase I program is a continuation of the materials development completed internally at ANI. If successful, the technology developed through this project will provide and accurate, robust, reliable and cost effective.

There are several diseases that are attacking citrus crops world-wide. The citrus industry desperately needs early detection of these infections. However, there are no low-cost, robust diagnostic tests currently available for early identification of citrus diseases under field conditions. This proposal directly responds to the need to reduce the impact of plant diseases and insect pests on citrus crops by developing a means of early detection.Canine detection of citrus diseases is now being applied and shown to be effective. Canine detection is dependent on the recognition of the unique odor signatures. We are proposing to develop a low-cost (< $2 per sample) odor sampling test-kit that will be user-friendly and applicable to both grove owners as well as residential owners who have citrus on their residential property. We propose to develop a sampling technology and process that does not require highly trained technicians and expensive equipment.Rapid and early detection of the citrus deseases will limit the spread of these diseases and lower the cost of citrus production.

Applied Nanotech, Inc. proposes to partner with a leading thin-silicon solar cell manufacturer to develop highly flexible, dielectric backplane materials. ANI and its partner will take advantage of the flexibility of thin-silicon and work to provide support solutions that have excellent adhesion and do suffer from delamination. The thin-silicon technology can currently produce solar cells with greater than 200W/m2 power density. The focus of this SBIR will be to demonstrate reliability and flexibility for field deployable applications.

In studies conducted for the Centers for Disease Control and Prevention, it was estimated that approximately 48 million new cases of food-related illness, resulting in 3,000 deaths and 128,000 hospitalizations, occur in the United States annually. These estimates, although lower than previous estimates, confirm that foodborne illness continues to be a problem. Together with the mortality and quality-of-life costs, foodborne illness places a tremendous burden on our society. It is even more of a burden in developing countries. There is no doubt that there is a need for low-cost, rapid detection of micro-organism in our post-harvest food processing and distribution network.Bacteria, as well as fungi produce VOC signatures that are a product of primary and secondary metabolism pathways, thus providing a means for quick, reagentless testing for foodborne pathogens. This proposal is responsive to the USDA SBIR Program Priorities as it addresses the need for a quick (minutes), point-of-test analysis for critical food borne pathogens.The Phase I efforts will provide the information needed to prove the feasibility of detecting foodborne pathogens on representative foods (spinach and netted cantaloupe) for two common foodborne pathogens (Shiga toxin producing E. coli and Listeria). We will measure the odor signatures from these inoculated samples against clean, non-inoculated controls. In parallel we will perform PCR and microbiological tests that are generally accepted protocols for measuring activity of these foodborne pathogens on these food types. The Phase I effort will demonstrate technical feasibility by establishing the level of detection of foodborne pathogens on food types that have a history of contamination with these pathogens in our food supply chain. The pathogens were also selected as there were among the most costly and common foodborne pathogens and are also of specific interest to USDA. The Phase II effort will expand our effort to include salmonella and campylobactor species. We will also develop an engineering prototype EZKnowz & trade; sensor platform that is optimized for food safety applications. One goal will be to achieve sampling and analysis time to less than 2 minutes.Should our program be successful, the technical benefit will be a low-cost, hand-portable, field-ready instrument that can provide fast (2 minute) and reliable (as compared to currently acceptable techniques) sensor for common foodborne pathogens. We will initially focus on bacterial pathogens but this could be expanded to viral pathogens as well. The economic benefit will be a tool that can be used in finding and managing foodborne pathogens at all levels of the food production chain, from field analysis to post-harvest distribution and sale. Even a decrease of 10% in the number of foodborne illness cases can lead to billion (USD) in savings an improved quality of life. It will even save lives.Benefits outside of food safety include recent studies which have shown the EZKnowz & trade; to be a potentially significant new technologyfor detecting multidrug-resistantpathogensin clinical as well as hospital-acquired infections, accuratelyidentifyingnosocomialpathogens.

Conductive patterns are formed using formulations containing metallic particles, which may be copper. These metallic particles may be coated with a binder material that improves adhesion during photosintering of the formulations. The binder contains chemistry suitable for it to be removed from the particles in a separate process such as drying or thermal sintering. The coating is a non-volatile organic compound attached to the metallic particles with a minimum thickness oxide coating. The organic coating improves a coefficient of thermal expansion value match between the metallic particles and the substrate, which may be polymeric.
