The purpose of this Phase I program is to demonstrate the feasibility of a compact, frequency tripled Nd:Y2O3 laser system to generate 305nm and 315nm for global tropospheric ozone sensing from space. Because Nd:Y2O3 can generate output on both the 915 nm transition and the 947 nm transition, the desired ozone UV DIAL wavelengths of 305 nm and 315 nm can be generated using a SINGLE laser device th ...

Both pyrolysis and incineration steps have been considered as the key solid waste processing step for a Controlled Ecological Life Support System (CELSS). Pyrolysis is more amenable to handling mixed solid waste streams in a microgravity environment, but produces a more complex product stream. Incineration produces a simpler product stream, but the incineration of mixed solids is a complex unit op ...

The NASA objective of expanding the human experience into the far reaches of space will require the development of regenerable life support systems. On-board carbon dioxide (CO2) removal units play a key role in such systems ensuring high quality cabin air for crew members. Similar but more compact units are needed for extravehicular activities (space suit). The overall objective is to develop a C ...

Advanced Fuel Research, Inc. (AFR) has developed a technology to provide radiation shielding, while simultaneously increasing the capacity of hydrogen storage tanks. This technology uses carbon foam filler with a complex pore structure (?microporosity?). The tank with the filler has, counter-intuitively, more capacity to store hydrogen than an otherwise empty tank. This technology increases hydrog ...

High temperature capacitors based on a new family of ferroelectrics are proposed. The Curie temperatures of the (1-x)BiMeO3 - (x) PbTiO3 (Me = Sc, In, Yb, or Fe) family have been found to range from 450C to >600C. Multilayer ceramic capacitors based on these materials offer a distinct advance in the working temperature compared to currently available devices. The aim of this Phase I project is to ...

Ongoing logistical repair, maintenance, and resupply of space platforms will become a costly and potentially dangerous activity in the post Space Station era. This is primarily driven by the need for more frequent missions, and as the number of missions increases, so does the cumulative probably of failure in the launch, docking, and return phases of the mission. The best defense will be to make s ...

The objective of the proposed effort is to develop a novel technology that will provide a unique and powerful alternative to conventional flow cytometry. This new system, which we call a cytometer on a chip will spatially sort cells on a microarray chip based on the presence of specific cell surface receptors or other surface features. Detection and quantitation is accomplished with grating-couple ...

The innovation proposed is the construction of a unified nonlinear turbulence model for use in jet noise studies that will operate in an invariant manner (fixed coefficients/correction terms), and will provide reliable mean flow and anisotropic stresses predictions for a broad range of jet conditions. Model construction will be based on extensions to an operational explicit algebraic stress model ...

Computational analyses aiding experimental testing of rocket propulsion systems have very rigorous requirements relating to turnaround time and fidelity of analyses. The performance of rocket propulsion systems is intricately tied to the functioning of valve and feed systems, since feed systems exert flow control, regulate pressure and suppress instabilities. CFD based analyses of such systems is ...
