Three-dimensional woven and braided fiber architectures provide important advantages to composites, including suppression of delamination, high damage tolerance, improved through-the-thickness properties, simplicity and cost-effectiveness of manufacturing complex composite structural components. However, in order to diversify applications and reach high volumes of utilization of these materials in ...

DNA microarray technology, in combination with statistical and predictive modeling tools, could be used to evaluate thousands of genes against distinct gene expression patterns induced by chemical/biological agents to provide early identification and speed therapeutic intervention. The overall objective of this Phase II effort is to leverage existing public domain resources and commercial tools t ...

An effective surface flow controller for the manipulation of the properties of aerodynamic boundary layers, particularly the resulting body drag and airflow attachment, has been long sought after. The goal has always been a surface airflow controller that is able to manipulate the aerodynamic boundary layer while both saving fuel (reducing power consumption) and improving the aircraft performance ...

Atmospheric Glow Technologies proposes to develop the Plasma Agent Neutralization Elimination (PLANE) System based upon its patented One Atmosphere Uniform Glow Discharge Plasma (OAUGDP) technology. When developed, this advanced design will serve as a system for the decontamination of aircraft and associated cargo. AGT has demonstrated the success of OAUGDP in decontaminating various substrates ...

THE VLSI AND VHISC DEVELOPMENT PROGRAMS OF THE AIR FORCE REQUIRE CHARACTERIZATION OF III-V COMPOUNDS WITH AN INTERFERENCE FREE, HIGHLY SENSITIVE ELEMENT ANALYSIS TECHNIQUE HAVING GOOD LATERAL AND DEPTH RESOLUTION. SPUTTER INITIATED RESONANCE IONIZATION SPECTROSCOPY (SIRIS), AN ULTRASENSITIVE ANALYTICAL TECHNIQUE DEVELOPED BY ATOM SCIENCES, HAS BEEN DEMONSTRATED IN SILICON TO HAVE GOOD SENSITIVITY ...

Insuring the safety and control of littoral waters is problematic because of the difficulties of surveillance. The preferred methods of surveillance in the ocean are acoustic. In littoral waters, acoustic methods fail because noise from the surf and reflections from the shallow bottom convolute acoustic signatures beyond our capacity to discern them. Water absorbs light, reducing the effectiven ...

THE OBJECTIVE OF THIS PROPOSAL IS TO CONDUCT PRELIMINARY TESTS ON A NOVEL CHEMISTRY WHICH COULD RESULT IN THE PRODUCTION OF A LOW COST WAFER WHICH CHANGES COLOR UPON EXPOSURE TO WARFARE GASES (WG). SIMILAR WAFERS WHICH WE DEVELOPED FOR OTHER GASES ARE ABOUT 2" X 1" X 1/16" AND WEIGH ABOUT 2.3 GM. THESE CHROMOSENSE (TM) WAFERS CAN DETECT HYDROGEN SULFIDE, ETC. IN 10-30 SEC. AT CONCENTRATIONS OF THE ...

Superconducting coils are capable of storing considerable amounts of energy. Should a coil quench, due to overheating or exceeding the critical field or current, the stored energy in the coil must be dissipated safely - without endangering personnel or damaging the coil or control systems. In any superconducting coil design, it is essential to design and build the system such that limits of the ...

In phase I, Dot Metrics Technologies demonstrated the feasibility of a new method of introducing deep-green luminescent nanostructure into semiconductor materials for light-emitting device applications. The materials were used to fabricate and characterize preliminary optoelectronic device test structures. In phase II, Dot Metrics Technologies proposes to leverage these new materials and methods i ...

Taggants are small objects used to label things or people that need to be traced. Synthetic DNA Taggants are ideal for this, since very small amounts can be detected if the sequence is known, and can be disguised by natural DNA in the environment. Known protocols for DNA amplification (e.g. PCR) allow for very sensitive DNA detection, but suffer from disadvantages: the apparatus is not very portab ...
