Award Data

Future lunar and planetary explorations will require the storage of cryogenic propellants, particularly liquid oxygen (LOX) and liquid hydrogen (LH2), in low earth orbit (LEO) for periods of time ranging from days to months, and possibly longer. LEO is a relatively warm thermal environment and without careful thermal management, significant quantities of stored liquid cryogens can be lost due to ...

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). This Small Business Technology Transfer Phase I project is for the development of ultrahigh thermal conductivity carbon fiber for use in graphite-metal composites. The use of graphite fiber in a metal matrix produces a composite with high thermal conductivity and controlled CTE, the two key requirem ...

In this NASA Phase I STTR effort, the feasibility of fabricating isolated ridge waveguides in 5% magnesium-doped lithium niobate (5% MgO:LN) will be established. Ridge waveguides in MgO:LN will significantly improve the power handling and conversion efficiency, increase photonic component integration, and be well suited to space based applications. The key innovation in this effort is to combine ...

We propose to design, construct and test a first implementation of a non-dispersive technique for the measurement of atomic absorption in the plumes of liquid rocket engines in altitude test facilities. Led by NASA Stennis Space Center (SSC), the observation of metal atom emission from liquid rocket engine exhausts at sea level conditions has become a highly successful health monitoring technique ...

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). This Small Business Technology Transfer Phase I project will develop a low cost manufacturing process for a carbon nanotube based (CNT) dry adhesive that emulates the mechanical properties of gecko feet and that can be scaled up to a large scale. The superior performance of CNT dry adhesives will si ...

DESCRIPTION (provided by applicant): Targeted Pb-212 therapy in preclinical animal tests has shown a cure in groups receiving the highest dose of this therapy. Scaling the dose that was most efficacious in animal studies to people would bring the human dose required from 50 to 100 mCi. This application will research an approach that would provide a generator system that would support these require ...

DESCRIPTION (provided by applicant): Injury is a well established risk factor in the pathogenesis of osteoarthritis (OA) as supported by several large longitudinal population studies. Patients with meniscal and ACL injuries in particular are at risk for early OA. Chondroprotection of the joint surface is mediated by lubricin which forms an ordered nanofilm and provides anti-adhesion via steric rep ...

Middle-wave infrared (LWIR, 3.2-3.6 ƒÝm) photodetectors with a high specific photodetectivity (D*) are of great importance in NASA¡¦slidar and remote sensing applications. However, existing MWIR photodetectors are required to be operated at low temperature of below 77K to achieve high photodetectivity (D*). The requirement for cryogenic cooling systems adds cost, weight and reliability issues, ...

This Small Business Technology Transfer Phase I project is to demonstrate a new Coupled Quantum Dot (CQD) multifunctional material. Electron-tunneling and inter-quantum dot coupling effects will be analyzed. The tunable energy bands of the new CQD material will be simulated. Successfully performing the proposed research will provide an enabling multifunctional CQD material platform that allows th ...

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). This Small Business Technology Transfer Phase I project will investigate transparent metal oxide nanostructures, especially zinc oxide and titanium oxide, suitable for a wide range of applications that require transparent conductors. If successful this project will create low cost transparent electr ...
