WE PROPOSE TO SEARCH FOR NEW SUPERCONDUCTORS THAT ARE SIMILAR TO THE PEROVSKITE-BASED HIGH TEMPERATURE SUPERCONDUCTORS (HTS), BUT WITH THE OXYGEN REPLACED BY A CHALCOGEN, THAT IS SULFUR, SELENIUM OR TELLURIUM. WE BELIEVE THAT THE HTS COPPER OXIDES ARE NOT A UNIQUE ACCIDENT OF NATURE, BUT THAT THERE ARE OTHER COMPLEX CHEMICAL COMPOUNDS THAT COULD ALSO BE SUPERCONDUCTING. AN OBVIOUS PLACE TO LOOK WO ...

This project seeks to demonstrate the practicality of using resonant circuit techniques to excite the field of specially designed high frequency alternators for the efficient production of 60 Hz AC power. The project will also explore the practicality of controlling the resonant excitation so that the device power output can be synchronized with and n coupled to an existing power grid. Tests will ...

This program on high-strength piezocermaic fibers probes a critical gap in the technology of smart materials which interconvert electrical and mechanical energy. Strong piezoceramic fibers that can function as load bearing members in structures and survive the large mechanical strains encountered in highly stressed engineering components are not developed. It is envisioned that piezoelectric fabri ...

To continue the development of low cost carbon composite material, this program is intended to demonstrate the ability to fabricate net shape tubular space truss components using co-braided carbon and thermoplastic (PEEK) yarns. The thermoplastic yarn, when processed through an autoclave cure using high pressure and temperature, will fuse the high modulus carbon fibers together to form a rigid fin ...

This Phase I SBIR demonstrates the underlying technology required to construct an ultraspectral imager that has the ability to spectrally resolve molecular absorption lines while simultaneously creating a two dimensional spatial mapping. The proposed instrument will have a spectral resolution that is better than 2 cm-1 and two dimensional spatial resolution that exceeds 2 milliradian. Based on Fou ...

MRC PROPOSES TO DEVELOP A SAFETY PERFORMANCE INDICATOR (PI) OF THE ELECTROMAGNETIC (EM) PROTECTION STATUS OF A NUCLEAR POWER PLANT (NPP). WE BELIEVE THAT SUCH A PI IS NEEDED BECAUSE: (1) EM ENVIRONMENTAL POLLUTION IS ON THE INCREASE,(2) ADDITIONAL EM THREATS MUST BE EVALUATED, AND (3) DISRUPTION OF NPP OPERATIONS BY EM EFFECTS CAN AND MUST BE AVOIDED. PREVIOUS STUDIES HAVE ADDRESSED THE ISSUE OF E ...

Sensors, capacitors, and conducting features such as resistors and capacitors on circuit boards are produced from metal and ceramic powders 1-12 These powders are manufactured by liquid phase precipitation routes which often start with reduction of metal salts or by solid-state routes where solid reactants are mixed, heated and then milled. The solid-state processing is generally repeated several ...

Optomec Design Company proposes to use Laser Engineered Net Shaping (LENSTM), a Rapid Prototyping and Manufacturing (RP&M) technology currently under development at Sandia National Laboratories (SNL), as a new method for integrating instrumentation (e.g., embedded sensors) into metal structural components. SNL has demonstrated the ability of the LENSTM technology to produce near net shape stainles ...
