The use of enzyme-linked immunosorbent assay (ELISA) to detect contaminants such as solvents, fuels, and pesticides in soil and water samples is now well established. Although ELISA and related methods can facilitate analysis of samples, several washing and separation steps are involved that require 30 to 120 minutes per sample to reach equilibrium. Recently, near infrared fluorescence immunoassa ...

This Small Business Innovative Research Phase I project seeks to combine the enhanced piezoelectric properties of single crystal perovskite ferroelectrics, recently discovered at Pennsylvania State University, with the electrostrictive properties of polyurethane to make a new class of "smart" materials for acoustic transducers. A tape casting process is used to form composite sheets compromising ...

Significant similarities exist between DoD simulation applications and networked simulation games developed for entertainment. To date, however, there has been no compelling reason for commercial game developers to adopt DoD methods and standards. Interestingly, HLA compares favorably to current commercial solutions like Microsoft's DirectPlay. There is clear benefit to DoD if HLA is embraced b ...

This Phase I project will investigate using scrap tires to form a protective system for mitigating local scour around bridge piers. Local scour is the erosion of the riverbed around bridge piers, which is induced by the recirculating juncture flow at the intersection of the pier and the riverbed. Bridge failure caused by this phenomenon has long been an important issue with respect to both publi ...

The Clean Air Act of 1990 has raised the concern over trace concentrations of metals in flue gas from electrical generation plants, municipal waste incinerators, and heavy industrial plants. Monitoring will be required to determine the environmental impact and offers an opportunity to empirically minimize it. In flue gas, metals are found in both the vapor state and condensed on fly ash. For sp ...

The contractor proposes a new approach to underwater imaging that directly converts a two-dimmensional acoustic pressure wave into an electronic requirements fo convential piezo-element arrays. The imager relies on the piezo-birefringent properties of a nematic liquid crystal panel that serves as both sensor and display. The capability of nematic liquid crystals has been established and publishe ...

The objective of the proposed program is to address the high service costs of the current U.S. Navy fleet of aircraft by developing a distributed optical fiber sensor system that will help reduce the costs associated with corrosion damage and extend the lifetime of existing aircraft. Annual corrosion of Navy metallic structures has been estimated as high as $1 billion. Additional costs aris ...

In this proposal, we describe a novel approach for realizing a parallel, nonmechical, read/write interconnection for angle-multiplexed three-dimensional (3-D) optical memories. Our concept represents a significant first step required toward taking this critical memory technology from the laboratory and inserting it into operational systems. The concept utilizes novel optomechanical packaging and ...

In this Phase I research project, Material Innovation, Inc., will develop a biodegradable and environmentally benign hydraulic fluid that minimizes hazardous pollution caused by accidental fluid spillage, lowers disposal costs of the used fluid, and helps the user industry to comply with environmental safety regulations. The operating temperature range for this hydraulic fluid will be from -54?C ...
