Emissions of volatile organic compounds (VOCs) and hazardous air polutants (HAPS are a serioud environmental issue. These pollutants are requlated to protect human health and encourage the development of better control technologies. Current technologies to control thses emissions, until better materials are developed, include destructive and/or recovery-based technologies. Implementation of ads ...

Various technologies available to space system designers that operate at different voltage levels. It is, however, important to interface, maintain, and update these systems. For example, the Sun Earth Connection (SEC) missions are likely to have a variety of experiments needing to be accomplished with a single nanosatellite. A rad-hard reconfigurable bi-directional level shifters would allow th ...

A high efficiency low scatter echelle grating will be developed using a novel technique of multiple diamond shaving cuts. The grating will have mirror surfaces on both faces for high efficiency in high orders. The grating will be manufactured using a 3/4 ton air bearing grating carriage that oscillates at 30 strokes per minute between two non-contact magnetic fields. The groove spacing will be con ...

High sensitivity HgCdTe infrared arrays operating at 77K can now be tailored in a wide range of wavelengths from 1 to14 um. However, the cooling requirements make them bulky and unsuitable to be incorporated into robust autonomous sensor systems. We propose to develop detectors with high detectivity that operates at or near room temperature in the MWIR (3 to 5 um) and LWIR (8 to 12 um) atmospheri ...

Several studies over the past few decades have recognized the need for advanced propulsion to explore the solar system. As early as the 1960s, Werner Von Braun and others recognized the need for a nuclear rocket for sending humans to Mars. The great distances, the intense radiation levels, and the physiological response to zero-gravity all supported the concept of using a nuclear rocket to decre ...

Manning Applied Technology proposes to develop a handheld infrared spectrometer, ideally suited to detection of airborne chemical agents at and below permissible exposure limits. This approach offers unmatched sensitivity and specificity for detection of all types of chemical vapors. The instrument is modular, rugged, compact and highly sensitive. Volume pricing will be less than $1000 each. ...

High-speed devices using InP play a critical role in the realization of power amplifiers for wireless and optical communication systems. Current gain cut-off frequencies in excess of 200 GHz have been demonstrated for InP HBTs, indicating the potential of these devices for use in high bandwidth communication systems and high-speed direct digital synthesizers. To achieve a higher output power and ...

The overall objective of this proposal is to demonstrated that imidazenil is a more potent and safer protective agent than diazepam against chemical warfare nerve agent (CWNA)-induced seizure/status epilepticus, neuropathology, and neurobehavioral deficits. Thus we will compare the dose-dependent efficacy of imidazenil or diazepam administered alone and in combination with levetiracetam in protect ...

Lithium has been proposed as an attractive metal propellant for advanced nuclear-electric propulsion missions in the outer solar system. While it is low molecular weight for high Isp and had high conductivity for MPD acceleration, it is also corrosive to most metals, leeches elements from alloys, destroys dielectric insulators and is heavily prone to contamination. Porous metal electrodes, valves ...

The innovation (AGATE, for Autonomous Go And Touch Exploration) will enable single-sol "go and touch" instrument placement from distances of up to five meters for scientific exploration rovers. It will reduce the number of sols required to examine objects of scientific interest, while increasing the accuracy of instrument placement relative to visually-specified targets. AGATE, based on the propo ...
