High performance steels were developed in a cooperative program between the Federal Highway Administration (FHA), the American Iron and Steel Institute (AISI), and the U.S. Navy Carderock Division of the Naval Surface Warfare Center. HPS70W high strength steel is currently being used in bridge structures. HPS is stronger than conventional 70W steel and has less than 15% of the sulfur and 60% of th ...

Gas-Liquid separation is an acute microgravity problem. Existing devices use centrifugal motion on microporous membranes to separate the two phases. Centrifugal devices consume electricity and are prone to failure. The microporous membranes easily foul and have significant water loss. Novel membrane devices are proposed. Membranes can simultaneously disengage gases from gas-liquid dispersion and d ...

Reliable monitoring of the microcrack formation in the complex composite structure components in NASA spacecraft and launch vehicles is critical for vehicle operations. Early diagnosing and reporting vehicle capability has tremendous impact on mission readiness, safety, and life cycle cost. Microcrack formation in complex composite structure components can be challenging from a monitoring and eval ...

Illinois Rocstar LLC proposes to develop and demonstrate the use of an integrated computational environment and infrastructure for electrochemical device design and simulation: ICED. This environment integrates the user's personal computational environment with high performance simulation applications for materials and processes. The current state of the art for electrochemical device design utili ...

National Aeronautical and Space Administration's (NASA) Aviation Safety Program "seeks capabilities furthering the practice of proactive safety management." Specifically, one of the key interests in Topic A1.04 are proposals for Remaining Useful Life prediction techniques. In response, Nokomis is proposing to develop an Electronic Health Monitoring (EHM) Sensor Unit which would be able provide a ...

The proposed innovation will dramatically improve the performance of tritium-powered betavoltaic batteries through the development of a high-aspect ratio, expanded surface area p/n junction composed of indium gallium phosphide. The enhanced surface area features will be built using reactive ion etch (RIE) modified germanium substrates via metalorganic chemical vapor deposition (MOCVD). The propo ...

The proposed program will develop titanium/water heat pipes suitable for Spacecraft Fission Power. NASA is examining small fission power reactors for future space applications with the most recent being Kilopower, which provides roughly 1 kW of electric power. Kilopower uses titanium/water heat pipes to remove the waste heat from the cold end of the convertors. Previous water heat pipe designs f ...

XABC (Xerion Advanced Battery Corp) proposes a novel anode with three unique features, each designed to 1) control or 2) prevent dendrite growth. The first feature is a 95% porous electrode architecture. This electrode is an open-cell, nanostructured conductive foam whose internal structures are conformal coated with lithium metal. Dendrites growing outward from an internal pore surface will propa ...

Future NASA exploration missions require high specific power (>500 W/kg) solar arrays. To increase cell efficiency while reducing weight and maintaining structural integrity, we propose an approach to cell design that involves the use of quantum dots and epitaxial lift-off. In the near term, this approach will allow us to improve on what are currently the best space solar cells available in term ...

This Phase I SBIR project seeks to develop a 500 Wh/kg Lithium primary battery for intended application as the primary power source on landers and probes for future missions to Titan/Enceladus and near Earth asteroids. The proposed battery technology aims to offer a viable alternative to Li/SO2 primary batteries which were used in the most recent mission to Titan. A thorough analysis of power requ ...
