To produce power more efficiently and cleanly, the next generation of power turbines will have to operate at extreme temperatures and pressures. Currently, single-crystal, nickel-based superalloys are used in such extreme environments. MCrAlY coatings (where M = Co, Ni, or...

Extraction of oxygen from the abundant carbon dioxide present on Mars (96% atmospheric composition) is an important objective in preparation for missions to the planet. Oxygen is not only a fundamental reactant with high-specific-energy chemical fuels such as hydrogen and methane, but, along...

NASA’s endeavor to further enable long-duration manned space exploration requires further closure of the oxygen loop of the life support system that is currently realized aboard the International Space Station. Currently, oxygen is recovered from crew-generated carbon dioxide via the use of a Sabatier...

This invention relates to the process of coating substrates with one or more components to form a catalyst; specifically, the process of layering one or more catalytic components onto a honeycomb monolith to form a carbon monoxide oxidation that combines CO and O2 to form CO2, or...

Amperometric electrochemical sensors are commonly used for the detection of carbon monoxide (CO) and hydrogen (H2) in air. The electrochemistry of heterogeneous CO and H2 oxidations is similar enough that the sensors show significant cross-sensitivities between the two gases. Thus, in...

A mobile device application created by NASA visualizes recent global climate data from Earth science satellites, including air temperature, sea surface salinity, carbon monoxide, ozone, and water vapor, as well as gravity and sea level variations. This app is an Open GL simple 3D object viewer for the Apple IOS and...

Oxygen produced from lunar resources is a very desirable product to greatly reduce the mass lifted from the Earth’s surface in support of exploration activities. The ability to obtain high yields of oxygen from undifferentiated lunar soils enables planning for near-term piloted missions to the Moon. One...

Emissions from fossil-fuel combustion contribute significantly to smog, acid rain, and global warming problems, and are subject to stringent environmental regulations. These regulations are expected to become more stringent as state and regional authorities become more involved in...

The Lunar Organic Waste Reformer (LOWR) is a novel technology to convert organic wastes from human space exploration outposts into useful propellant constituents. The LOWR meets NASA’s Trash to Supply Gas (TtSG) objective under the Advanced Exploration Systems Logistics Reduction and Repurposing project by integrating...

A modified oxidation catalyst material can be used to build a carbon-monoxide-sensing electrode for amperometric sensors to overcome the typical cross-sensitivity of these sensors toward hydrogen. The technology will have applications in the emerging hydrogen fuel cell economy...
