Ozone treatment of wastewater to destroy organic contaminants prior to discharge into the environment is an extremely effective advanced oxidation technology. To date the use of this powerful technology has been limited in part by the relatively high capital costs of an efficient ozone to water, gas-liquid, mass transfer system. Existing ozone injection devices must overcome the inherently low m ...

Lean burn spark engines are a promising technique to further reduce both NOx and hydrocarbon/carbon monoxide (HC/CO) engine emissions. Higher lean burn levels improve HC/CO oxidation while simultaneously reducing NOx formation. The NOx reduction is due to cooler flame temperatures. While the lean burn limit (beyond which combustion is poor) restricts further emission reductions, the use of oxyg ...

A 300 Kw permanent magnet brushless dc motor with axial gap configuration to fit within 23 inch diameter by 10 inch long package is proposed for tracked vehicle applications. The stator constructed using novel concepts results in under 24 p.s.il, 4.4 gallons/min. oil flow to keep the maximum winding temperature under 200 deg C. The motor voltage is limited to 500 Vdc, and the efficiency including ...

The photographic industry consumes about 70 million troy ounces of silver annually. The technology used to recover the silver from concentrated solution is more than 40 years old. However, investigators project that, based on industry experience, as much as 20% of this silver is lost in the wash water and goes unrecovered. The toxicity of silver in the effluent is a growing concern in the United ...

The performance of Zaromb Research Corp.'s proprietary portable high-throughput liquid-absorption air sampler (PHTLAAS] will be upgraded so as to yield a collection efficiency of at least 30% for micron-size microorganisms at a sampling rate of at least 350 1/min of air and a power consumption of under 40 watts. The collection efficiency of the improved PHTLAAS will be measured in a wind tunnel u ...

The goal of this development effort is to provide warfighters with inexpensive methods to view geospatial intelligence information on a hand-held tablet through their sense of touch. This allows eyes-free and silent operation without generating light. This proposal deals with two surface haptic display technologies. Variable-friction displays create haptic effects by varying the coefficient of fri ...

Technical Abstract (200 word limit): While state-of-the-art microbolometers demonstrate impressive capabilities for low-cost uncooled long-wavelength infrared (LWIR) imaging, there is currently a need for low-cost, mid-wavelength infrared (MWIR) imaging systems capable of high performance with fast frame rates at high operating temperatures. HgTe colloidal quantum dot (CQD) focal plane arrays (FPA ...

To reach the end user, oil and gas production at the wellhead must be transmitted through the country and distributed to a wide range of customers. This logistical system requires natural gas gathering lines, processing facilities, product storage tanks and lots of other equipment. What results is air pollution caused by industry losses during these operations and the use of continuous or intermit ...

Metal-organic frameworks (MOFs) are adsorbents that show promise in toxic chemical remediation, medical oxygen storage, high-value gas recovery, and multiple other military and civilian applications. However, a lack of quality-controlled supply limits these materials to laboratory environments. This work will borrow from industrial Quality practices to ensure supplied material conforms to specific ...
