Chlorine gas was first used as a weapon during World War I, and reemerged as a threat in Iraq compounding the dangers from existing improvised explosive devices. One of the significant challenges with preventing attacks that involve toxic industrial chemicals (TICs) like chlorine and ammonia is that they have genuine civilian uses for water treatment, in refrigeration systems, and other applicatio ...

For applications in DoD satellite systems, devices based on novel nanomaterials offer significant advantages over traditional technologies in terms of light-weight and efficiency. Examples of such novel devices include quantum dot (QD) based solar cells, photodetectors, radars and sensors. However, the response of these devices to radiation effects is not well understood, and radiation effects mod ...

A significant amount of personal injury and property damage as well as lost productivity could be avoided by speeding up the body’s adjustment cycle to new circadian schedules or re-synchronizing body schedules that have slipped or advanced. For the military, this problem is especially acute because the warfighters’ duties include dangerous equipment and a need for 24-hour operational readine ...

Within harsh environment areas, Naval vessels require illumination. Incandescent based Symbol 48.2 explosion-proof fixtures are rated to operate in these spaces but are inefficient, resulting in unsafe fixture surface temperatures and unnecessarily high energy consumption. Under such extreme operating conditions, the lamps in the fixtures fail frequently, leading to high maintenance costs. Prod ...

This Small Business Innovation Research Phase II project develops novel materials processing and device design that extract the maximum possible performance out of the lithium niobate electro-optic material. The novel modulator device incorporates reconfigurable quasi-phase matching (RQPM) to produce an arbitrary RF bandpass response. The Phase I effort has laid a firm foundation for the creation ...

Spatial light modulators are the limited component of optical signal processors. Electronic modulators, including liquid crystals and magento-optic modulators, are expensive, low resolution, and slow. The optical disk offers high resolution at moderate cost. The "pixel" size is on the order of one micron. The total system works to this accuracy by using an active feedback controlled system for ali ...

In recent years, major advances have been made in nearly all areas of microelectronics development, including silicon technology, software development, and chip architecture. The one key area that has been more-or-less neglected however is packaging. The technology of packaging minature electronics such that they do not overheat is now the limiting factor in miniaturization. Experimental evaluatio ...

The proposed research examines the feasibility of using solid oxide fuel cell (SOFC) for shipboard electric power generation by substituting new ceramic anode materials able to operate with logistic fuels. These anodes would allow the SOFC to operate witha range of reformed fuels containing sulfur impurities (including coal derived fuel gas, diesel fuel, jet fuel, and natural gas), avoiding the co ...

THE EXISTING METHODOLOGY OF DESIGN AND FABRICATION OF SEMICONDUCTOR MANUFACTURING EQUIPMENT IS AN EXPENSIVE AND TIME CONSUMING PROCESS. TO KEEP PACE WITH THE RAPIDLY ADVANCING SEMICONDUCTOR INDUSTRY, IT IS NECESSARY TO DEVELOP A COMPUTER BASED ENVIRONMENT TO QUICKLY SIMULATE THE FEATURES OF THE MANUFACTURING EQUIPMENT BEFORE IT IS TURNED INTO A PHYSICAL PROTOTYPE. APART FROM ACHIEVING CONSIDERABLE ...
