Fabrication of Single-Mode, Distributed-Feedback, Interband Cascade Lasers

Applications exist in the oil and gas industry, automobile emissions monitors, breath analyzers, and fire detection equipment. NASA’s Jet Propulsion Laboratory, Pasadena, California Type-II interband cascade lasers (ICLs) based on the GaSb material system represent an enabling technology for laser absorption spectroscopy in the 3-to-5-μm wavelength range. Instruments operating in this spectral regime can precisely match strong absorption lines of several gas molecules of interest in atmospheric science and environmental monitoring, specifically methane, ethane, other alkanes, and inorganic gases. Compared with non-semiconductor-based laser technologies, ICLs can be made more compact and power efficient, ultimately leading to more portable, robust, and manufacturable spectroscopy instruments.

Developing Ceramic-Like Bulk Metallic Glass Gears

This technology has applications in gears, bearings, and gearboxes for automotive, spacecraft, and robotics. NASA’s Jet Propulsion Laboratory, Pasadena, California This invention describes systems and methods for implementing bulk metallic glass-based (BMG) macroscale gears with high wear resistance. This invention creates bulk metallic glasses (BMGs) with selected mechanical properties that are very similar to ceramics, such as high strength and resistance to wear, but without high melting temperatures. Ceramics are high-strength, hard materials that are typically used for their extremely high melting temperatures. Because of their extreme hardness, ceramics are optimal materials for making gears, due to their low wear loss. Unfortunately, ceramics suffer from low fracture toughness (typically <1 MPa·m1/2), and their high melting temperatures prevent them from being cast into net-shaped parts. Ceramic gears, for example, must be ground to a final shape at great expense.

Product of the Month: March 2015

Instron, Norwood, MA, introduced the AVE 2 strain measurement system that conforms to testing standards such as ISO 527, ASTM D3039, and ASTM D638. The video extensometer utilizes patented measurement technology, and adapts to the normal fluctuations of indoor environmental conditions. It can be adapted to any testing machine that uses a ±10V analog input. Designed to reduce errors from thermal and lighting variations, the device uses the real-time 490-Hz data rate while achieving a 1-micron accuracy. It allows for testing under multiple environmental conditions and can be used for strain measurement with Digital Image Correlation (DIC). The device measures both modulus and strain-to-failure of most materials including plastics, metals, composites, textiles, films, and bio-materials.
