Exhaust Plume Analyzer
Exhaust plumes emanating from smoke stacks at power plants or other industrial facilities can have adverse impacts on local aviation during periods of calm winds. Adverse impacts can be exacerbated if the temperature is low or the atmosphere is unstable. While low oxygen concentrations and elevated temperatures inside the...
Briefs: Mechanical & Fluid Systems
Pulsed laser vaporization (PLV) production of single-wall carbon nanotubes (SWNTs) on traditional Co/Ni catalyst was explored with respect...
Briefs: Energy
Typical direct-injection engines, such as diesel engines, can produce soot due to fuel-rich combustion conditions. Filters and catalytic converters are currently used to reduce soot and harmful...
Briefs: Sensors/Data Acquisition
The detection and localization of gas releases, such as methane from leaking natural gas pipelines or nitrogen oxides from failing electrical equipment, require high sensitivity to the target gas and insensitivity to...
Briefs: Electronics & Computers
The exhaust heat recovery system (EHRS) in an automobile captures the thermal energy from exhaust and transfers it to the engine coolant. As the car warms up,...

Carbon Dioxide Collection and Pressurization Technology
Mars is the ultimate destination for NASA's human exploration program. In Situ Resource Utilization (ISRU) is a key technology required to enable such missions. The goals of using resources available at the exploration site are to reduce launch and delivered mass, reduce risk and cost, enable...
Briefs: Green Design & Manufacturing
Wind and solar energy generation creates challenges, since the Sun only shines by day, and sometimes the wind doesn't blow. Another variability is surges of demand on the grid. On a hot day...
Briefs: Test & Measurement
Particle analysis is useful for determining chemical compositions in a wide range of disciplines, from ascertaining the source of a petroleum sample to duplicating a fragrance. The technique is appealing to...

Geodesolver for the Geodesic Equation
NASA has a need to determine the distribution of dark matter around planets like Earth. Doing so necessitates the ability to repeatedly solve the geodesic equation in simulations of weakly interacting particles streaming through bodies described by a Schwarzschild metric. Geodesolver numerically solves the...
Briefs: Sensors/Data Acquisition
Recent findings indicate that frequent, short-term crew exposure to elevated CO2 levels, combined with other physiological impacts of microgravity, may lead to a number of...
Briefs: Green Design & Manufacturing
A method to capture carbon dioxide directly from ambient air offers a new option for carbon capture and storage strategies to combat global warming.
Briefs: Data Acquisition
Sensors that sniff out chemicals in the air to warn us about everything from fires to carbon monoxide to drunk drivers to explosive devices hidden in luggage have improved so...

Method for Establishing Cool Flames and Flameless Fuel Oxidation with Zero Emissions Using Non-Equilibrium Plasma Activation
Current engines and combustors run at high temperature, which leads to problems of engine knocking, soot and NOx emissions, and difficulty in combustion control. On the other hand, low-temperature combustion and fuel...
Briefs: Mechanical & Fluid Systems
NASA Kennedy Space Center seeks partners interested in the commercial application of the Quick Disconnect for High Pressure Mate/De-Mate. Designed at KSC, this technology is intended for use in...
Briefs: Sensors/Data Acquisition
A team at the New York University Tandon School of Engineering has made a discovery that could lead to Star Trek-like biosensor devices capable of flagging the...
Briefs: Imaging
NASA has developed a novel method to render visible the density changes in air that cause a refractive index change by an airborne vehicle. These density changes include shock waves, vortices,...
Briefs: Mechanical & Fluid Systems
Correlation spectroscopy is an attractive technique for sensing and analysis applications because it combines the attributes of mechanical and optical simplicity, high selectivity, and good sensitivity. In correlation...
