THE PROPOSED PROJECT WILL DEMONSTRATE THE FEASIBILITY OF EMPLOYING ELECTRON TRAPPING (ET) MATERIALS WITH FIBER OPTICS FILAMENTS FOR USE AS MICROPROBE RADIATION DOSIMETERS.THE ET MATERIALS TM CAN BE INTERROGATED BY NEAR-INFRARED TO PRODUCE VISIBLE OUTPUT SCALABLE TO RADIATION DOSES AT THE FIBER TIP. PHASE I WILL ASSESS THE PERFORMANCE OF SUCH MATERIALS AS MICROPORBE RADIATION DETECTORS INTEGRATED W ...

IONICS RESEARCH INC. (IRI) HAS DETERMINED THAT UNCOATED CAPILLARY COLUMNS CAN BE USED TO CONCENTRATE ORGANICS FROM WATER. THE METHOD IS EXCEEDINGLY SIMPLE AND RAPID (10 MINUTES PER 100 ML), YET EFFECTIVE. IRI PLANS TO INVESTIGATE THE POTENTIAL OF THIS TECHNIQUE FOR THE DEVELOPMENT OF AN INSTRUMENT SUITABLE FOR THA NALYSIS OF ORGANICS AT THE PART-PER-TRILLION LEVEL IN WATER AND WASTEWATER. SUCH AN ...

THIS PROPOSAL IS CONCERNED WITH THE ECONOMIC REMOVAL OF HYDROGEN SULFIDE, A TOXIC MATERIAL, FROM SOUR NATURAL GAS AND PETROLEUM PRODUCTS. THE CURRENT STATUS OF H2S PROCESSING IS REVIEWED. THE CHEMISTRY OF SULFUR AND SULFIDE IN AQUEOUS SOLUTIONS AND PRELIMINARY WORK ALREADY CARRIED OUT IN THE CONTINUOUS ELECTROLYSIS OF H2S TO YIELD HYDROGEN AND SULFUR ARE BRIEFLYDISCUSSED. THE ESTIMATED ECONOMIC GA ...

MODELING OF THE AMBIENT AND PROMPT IONOSPHERIC REGIONS IN A THIN LAYER APPROXIMATION ALLOWS AN EFFICIENT METHOD OF DETERMINING THE TIME EVOLUTION, PROPAGATION, AND SIGNAL STRENGTH OF THE 0-10 SECOND MHD EMP ASSOCIATED WITH HIGH ALTITUDE NUCLEAR DETONATIONS.

In this Phase I SBIR project for the DTRA, Energetics Materials and Products Inc (EMPI) of Austin, Texas, will develop an innovative technology to neutralize Improvised Explosive Devices (IEDs) without detonation or risk to personnel. Neither detonation nor defusing, the two methods currently available to neutralize IEDs, provide acceptable risk. Detonating the device is seldom practical in an u ...

A PHYSICAL PROPERTY OF EARTH FORMATIONS THAT STRONGLY INFLUENCES THE RATE OF ATTENUATION OF A SHOCK WAVE IS THE BULK VOLUME OF AIR OR GAS ENTRAINED IN THE POROSITY. AS A RESULT, THE ACCURATE DETERMINATION OF THIS GAS VOLUME IS IMPORTANT FOR PREDICTING THE EFFECT OF A SHOCK WAVE ON SUBSURFACE STRUCTURES. THE OIL AND GAS INDUSTRY HAS USED GEOPHYSICAL WELL LOGS FOR YEARS TO IDENTIFY AND EVALUATE THE ...

The proposed sorbents will have potential applications in i) industrial wastewater treatment plants, ii) municipal wastewater treatment plants, iii) nuclear waste treatment plants, iv) drinking water treatment plants, v) several types of existing point-of-use and point-of-entry water purifying systems, and vi) for remediation of various mercury contaminated sites using permeable reactive barrier ( ...

Harmful algal blooms (HABs) occur in aquatic environments when conditions trigger an increase in the abundance of organisms that produce toxins. The toxins are transferred through the food web where they affect and even kill zooplankton, shellfish, fish, birds, marine mammals, and possibly humans. HABs have been estimated to cost the U.S. economy as much as $50 million per year due to the closure ...

A low-impact delivery system for in-situ treatment if contaminated sediment is proposed. Unlike most conventional delivery systems that rely on injection or mechanical mixing of sediment, the proposed approach make use of natural mixing (bioturbation) processes to work treatment materials into the biologically-active zone. To accomplish this, agglomerates will be developed with the following pro ...

The sorbent proposed to be developed by Lynntech, Inc., in this Phase I project will have potential applications in: (1) industrial wastewater treatment plants, (2) municipal wastewater treatment plants, (3) nuclear waste treatment plants, (4) drinking water treatment plants, (5) several types of existing point-of-use and point-of-entry water purifying systems, and (6) for remediation ...
