Dr. Scott Barthelmy, Research Scientist, Laboratory for High Energy Astrophysics, Goddard Space Flight Center, Greenbelt, MD

Dr. Scott Barthelmy is the principal investigator for the Burst Alert Telescope (BAT), a sophisticated instrument that detects and precisely locates elusive gamma-ray bursts in the universe. Developed as part of NASA’s Swift mission, the instrument technology is now being considered for a variety of homeland security applications because of its ability to pinpoint and identify nuclear materials – both legal and illegal – in transit or storage. Dr. Barthelmy also created the Gamma-Ray Bursts Coordinates Network (GCN) to distribute data collected on gamma-ray bursts to researchers throughout the world in real time.

Low-Cost Engineered Properties for Non- Wovens, Films, and Laminates

A suite of nonwoven technologies offers low-cost mechanical processes that impart specific engineered properties to commodity-priced nonwovens, films, and laminates, and even to non-polymeric materials. A wide range of textures, controllable permeability, aperturing, multilayer composites, elasticity without elastic chemistry, and other features comprises various aspects of the suite. Many of the technologies operate at room temperature, without adhesives, and are suitable to high-speed lines (in excess of 500 FPM). They are compatible with production lines that may need to start and stop. They enhance the performance of low-cost materials — adding strength, puncture resistance, stretch, texture, permeability, and more — in ways that melt-based systems can achieve. They open potential new markets such as a new category of disposable fabric home goods (sheets, curtains, and pillows), new packaging options, and agricultural products.

Cooler, Quieter Jet Engine for Light-Sport Aircraft and Ultralights

A small jet engine is suitable for light-sport, ultralight, and experimental aircraft, and can replace the vibrating piston engine and propeller combination used in most sport aircraft. Exhaust heat is minimized for safety to 750 °C, so that a suitably insulated cowling can be touched. By minimizing the heat, sound absorbers can be used so that sound output of the engine is also minimized to about 200 dB or less at a measured distance from the exhaust. The engine provides much less vibration than does a conventional propeller and piston engine combination. The engine provides about 500 N (almost 370 foot-pounds) of thrust using a small compressor diameter and a high rotation speed. This engine produces inherently less noise, and in addition uses sound attenuation such as glass fibers and other materials formed as part of the exhaust tube, boundary layers, and other techniques. Using such sound attenuation, as well as bypass air, also serves to insulate the heat-producing portions of the engine from pilot, passengers, and ground personnel.

One-Megapixel Infrared Light Detector

A company seeks a detector array for the infrared region to detect two-dimensional radiation patterns. The sensor should have 1000 x 1000 pixels (or at least 512 × 640 pixels), which are individually addressable. The detector array is comparable to a high-speed CCD chip, but must have high sensitivity in the infrared around 1,300 nm.

Non-Fluoro-Based Textile Repellency Treatment

A company seeks a ready-to-use, non - fluorochemical - based repellent solution for oil- and water-borne stains for application on textiles. The textiles may be cotton, wool, or synthetic, or a blend of natural and synthetic fibers. This material may be fully formulated or partially formulated in a solventfree delivery solution.

Advancing Technologies Harness the Power of Wind, Water, and the Sun

Renewable energy will be the world’s fastest-growing source of electricity generation over the next two decades, although it will still make up a relatively minor portion of the global energy supply, according to the Energy Information Administration. The majority of that increase will come from the use of wind power and water power, or hydropower.
