Cement manufacture accounts for 5% of world CO2 emissions. Precast cement (15-20% of total in North America) requires CO2 during manufacture; the CO2 is not always available and it can be very costly. The object of this work is to develop and demonstrate a novel method to capture flue gas CO2 and then create a dry form, i.e., that can be incorporated in cement dry mix. The addition of CO2-equivale ...

High performance computing networks (HPC) require very high data transmission rates with large bandwidth. Fiber optic networks can meet the data transmission and bandwidth requirements. However, new component technology is needed to provide the interface to computer logic and memory systems, with are primarily silicon based electronics. Direct bandgap III-V semiconductor materials such as gallium ...

The subsurface plays a critical, multifaceted role in USA energy security. The subsurface contains energy resources (conventional and unconventional hydrocarbons as well as geothermal) and provides hundreds of years of safe storage capacity for carbon dioxide (CO2). As demonstrated by the impact of domestic non-conventional hydrocarbon production over the past ten years both USA energy security an ...

One of the mandates of NASA's Armstrong Flight Research Center (AFRC) is participating in the flight testing of experimental aircraft, which includes monitoring these tests with long-range, ground-based cameras. Because these cameras track and capture flight tests occurring multiple kilometers away, the imagery collected is often degraded by the atmospheric turbulence between the camera and subjec ...

NASA is planning to return to the moon in 2020 to explore thousands of miles of the moon?s surface with individual missions, lasting six months or longer. Surface mobility is critical to outpost buildup and exploration activities, where the change in the vehicle weight between unloaded and loaded cargo conditions and travel over rough terrain can adversely affect the ride handling conditions and ...

Earth observing missions like NASA's LANDSAT Data Continuity Mission - Thermal Infrared Sensor (LDCM-TIRS) require greater spatial resolution of the earth than the ~ 100m provided by the current instrument. Improving resolution to the desired ~ 30m requires increasing the number of pixels on target from the current 640x3 to ~ 2048x3. The TIRS instrument contains 640x512 longwave infrared quantum ...

The innovation is a fast, lightweight, and miniaturized Robotic Variable Interference Filter Imaging Spectrometer (R-VIFIS) for a 350-2500nm wavelength range. A pair of custom narrow band Linear Variable Interference Filters (LVIFs) is tailored with 350-900nm range (VNIR) and 900-2500nm range (SWIR) wedge coatings for a 35mm format CMOS Focal Plane Array (FPA) and a 384x288 pixel 24um pitch FPA re ...

Advanced space-borne instruments require cooling at temperatures of 10 K and below. These coolers will be used for as upper-stage cryocoolers for sub-Kelvin cryocoolers and instruments or the primary cooler for electro-optical instruments. Cooling loads for these detectors will range from 0.25 W to 1.0 W at the primary load site, with additional loads at higher temperatures for other subsystems. ...

NASA's future remote sensing science missions require advanced thermal management technologies to provide effective cooling for multiple instruments and reject heat through multiple radiators. Two-phase pumped loops are an ideal solution for these applications. A critical need for these pumped loops is a refrigerant pump that reliably circulates very slightly subcooled liquid refrigerant in the ...

This proposal will provide NASA with a family of UHF RFID sensor tags and system components supporting very reliable, robust, convenient and economical deployment into a range of aerospace and terrestrial systems. We propose designs that can be manufactured in quantity. Several of these tags have SPI,I2C and other data busses and adequate harvested power to enable on-tag microcontroller and mu ...
