Fastening and joining technology has lagged behind the progress that has been made in other areas of composites for advanced air vehicles. Aerotech proposes the development of reversible polymeric adhesive bonding of composites using variable frequency microwave energy. With this method, composites are bonded using Poly Ether Ether Ketone (a high temperature thermoplastic) which is cured using v ...

This is a Phase II proposal to continue the work begun by AgriTech Electronics, LC (AgriTech) on a GPS-based livestock control system. This system will exclude animals from areas, or contain them within defined boundaries, where it is impractical or inefficient to build fence to achieve this objective. These needs arise in a variety of contexts, including the exclusion of livestock from riparian a ...

DESCRIPTION (provided by applicant): Nitric oxide (NO) is a critical regulator of cardiovascular physiology, coordinating the activities of the endothelium, the vessel wall and circulating cells to optimize the flow of blood and oxygen to tissues. Increasing the bioavailability of NO should provide therapeutic benefit in the treatment of many diseases ascribed to insufficient NO bioavailability. A ...

DESCRIPTION (provided by applicant): Organ transplantation is one of the great success stories of modern medicine. However, the supply of suitable organs lags far behind the need and many patients die while waitlisted for organs. Current practice involves donor preconditioning to stabilize organs and tissues for transplant in attempts to increase the supply of donor organs acceptable for transpl ...

This Small Business Innovation Research Phase I research project will use femtosecond laser machining to fabricate Lithium ion based nanobatteries composed of arrays of nanocells. In addition, an array of addressable batteries will also be constructed. A femtosecond laser is a powerful tool to machine features on a variety of materials in the nanoscale regime. These batteries will be grown on flex ...

50540-98-I Imaging Fractures and Fracture Systems to Assess Reservoir Properties--American Spectrum Engineering and Science Services, 5010 Grand Central Drive, Morgantown, WV 26505-4797; (304) 284-9144 Mr. William K. Overbey, Jr., Principal Investigator Mr. William K. Overbey Jr., Business Official DOE Grant No. DE-FG02-98ER82528 Amount: $74,694 Many fractured gas reservoirs could be produced ...

Feasibility of fabricating IR window materials from aluminum nitride (AlN) will be demonstrated. Aluminum nitride windows are sought as replacements for sapphire windows on high speed seeker missiles because of their higher thermal shock resistance. Our approach is to consolidate high-purity ultrafine powders of AlN to obtain a nanocrystalline window. Small grain size is expected to minimi ...

The USAF recognizes that benefits to cold working fastener holes include significantly increased life of a structure subjected to fatigue loading. However, full realization of this potential from a maintenance and engineering standpoint is hindered by the fact that there is currently no adequate field technique for determining how well the material structure immediately surrounding the hole has re ...

The proposed approach for Phase I of this effort brings together two key items that are needed to work in concert with one another: advanced fatigue assessment methods and non-destructive inspection & detection techniques. Successful synthesis of these elements and the engineering disciplines behind them will provide an optimized and advanced method of taking full advantage of engineered residual ...
