AERODYNE'S SPECTRAL CORRELATOR TECHNOLOGY WILL BE ADAPTED TODETECTION OF METHANE IN ITS 3.3 UM VIBRATIONAL MODE. THE RESULTING FAST (10 HZ), ACCURATE (BETTER THAN 3% OF AMBIENT)INFRARED METHANE DETECTOR WILL BE DESIGNED (PHASE I), RUGGEDIZED AND OPTIMIZED FOR FIELD USE (PHASE II). WHEN COUPLED TO AND CORELATED WITH SONIC ANEMOMETER MEASUREMENTS OF TURBULENT EDDY VELOCITY FLUCTUATIONS, THE SPECTRAL ...

ISOTOPIC CARBON ANALYSIS PROVIDES A VALUABLE TOOL FOR STUDIES OF METABOLIC PATHWAYS AND FOR TRACING CARBON TRANSFORMATIONS IN THE ENVIRONMENT. THIS PROPOSAL WOULD DEVELOP AN OPTICAL TECHNIQUE FOR THE CONVENIENT MEASUREMENT OF CARBON ISOTOPIC ((13)C/(12)C) RATIOS. THE INSTRUMENT WILL UTILIZE A LINEAR PHOTODIODE ARRAY TO IMAGE THE SPECTRA ARISING FROM PLASMA EMISSION OF THE CARBON-CONTAINING MOLECUL ...

WE PROPOSE TO INVESTIGATE A TECHNIQUE FOR INCREASING THE SENSITIVITY OF INTRACAVITY LASER ABSORPTION SPECTROSCOPY, WITH APPLICATION TO THE DETECTION AND MEASUREMENT OF TRACE GASES IN THE ATMOSPHERE. THE TECHNIQUE THAT WE WILL INVESTIGATE IS TO PLACE A MULTIPASS ABSORPTION CELL WITHIN THE RESONANT CAVITY OF A DYE LASER. WITH AN INTRACAVITY MULTIPASS CELL, THE OPTICAL ABSORPTION PATHLENGTH CAN BE IN ...

This Small Business Innovation Research (SBIR) Phase I project addresses a method to achieve low-cost, high performance multiple-layer organic light emitting devices (OLEDs) by solution process. OLED is emerging as a next-generation display and lighting technology, they have a number of intrinsic advantages over liquid crystal displays including brighter and clearer displays, large viewing angles, ...

This SBIR Phase I research project will develop an innovative carbon nanotube water filtration membrane technology that will drastically outperform conventional filtration membranes. This project aims to improve performance by fabricating an ultra-high flux carbon nanotube filtration membrane through a solution-based material preparation technology. The goal of the carbon nanotube filtration mem ...

This Small Business Innovation Research (SBIR) Phase I project will develop and test a novel system for providing patients in physical and occupational therapy customized visual and aural feedback as a rehabilitation tool. The proposed 'augmented feedback' system will allow therapists to supplement their own verbalized feedback with visual and aural feedback concerning the subtle nature of a movem ...

A KEY CONSIDERATION IN A VARIETY OF MANUFACTURING PROCESSES IS CONTROLLING EITHER THE POSITION OR SHAPE OF AN INTERFACE DEFINED AS THE BOUNDARY BETWEEN LIQUID AND SOLID MATERIALS OF DISSIMILAR COMPOSITION OR DENSITY TO WITHIN CERTAIN ALLOWABLE TOLERANCES. EXAMPLES OF SUCH DIVERSE PROCESSES ARE VERTICAL FREEZE BRIDGMAN AND CZOCHRALSKI CRYSTAL GROWTH AND ELECTROSLAG REMELTING FOR METAL REFINEMENT. A ...

X-RAY PHOTOCATHODES ARE USED IN A LARGE NUMBER OF X-RAY IMAGING SYSTEMS, MAINLY IN THE FIELDS OF ASTRONOMY AND MEDICAL IMAGING. IN MOST APPLICATIONS, X-RAY PHOTOCATHODES ARE USED IN CONJUNCTION WITH A MICROCHANNEL PLATE (MCP) AND A POSITION-SENSITIVE DETECTOR. DEVICES INCORPORATING THIS COMBINATION ARE CAPABLE OF IMAGING X-RAYSWITH VERY HIGH SPATIAL AND TEMPORAL RESOLUTION. MANY DIFFERENT X-RAY PH ...
