A six-month, $91,305 Phase I SBIR program is proposed to perform ceramic-composition R&D aimed at cryogenic capacitors for the 120 - 240 K temperature range. Candidate compositions from three families of ceramics will be made under subcontract by NexTech Mat'ls Ltd and measured by CeramPhysics, 120 - 240 K (dielectric constant, loss tangent, frequency dependence, electric-field dependence, dielect ...

CdSe, a wide bandgap semiconductor, combining high resistivity, good carrier trans-port properties, and large average Z number is ideal for use as a room-temperature x-ray and y-ray detector. In the x-ray regime, the large bandgap (-1.7 eV) of GdSe eliminates the need to cool the crystal in order to reduce thermal noise. Si and Ge detectors must be cryogenically cooled, which precludes their use i ...

Glassy liquid crystals (GLCI represent a new emerging class of advanced organic materials which have significant potential for being readily processed into uniform optical quality thin films. In this proposal, we propose to develop high-performance optical filter and polarizer technology specifically for laser protection applications. The proposed GLC-based optical filters are specifically well su ...

Optical switches are fundamental components of survivable fiber network architectures. They are required to enhance the performance of fiber optic networks through load shifting and to provide disaster recovery when communication links are lost. Optical networks will likely be employed in the next generation of military air- and spacecraft (e.g. JAF) to provide communication links between avionic ...

Cornerstone Research Group, Inc. (CRG), and partner University of Dayton Research Institute (UDRI) will develop a suite of materials and processes as enabling technology for achieving the radical production time and cost reductions envisioned by the replication approach to producing composite mirrors for aerospace optics. CRG will formulate and demonstrate a high-performance polymer resin cured a ...

Cornerstone Research Group (CRG) proposes to develop and evaluate a novel encapsulation coating that protects thin film photovoltaic (PV) cells for the High Altitude Airship (HAA). The High Altitude Airship (HAA) is an unmanned, powered airship that is currently being developed to maintain a relative geostationary position at 65,000-70,000 feet. It is powered by regenerative fuel cells coupled wi ...

Extracting missiles from the highly structured cloud/solar background is essential to early missile detection. DRA will develop a system which uses several discrimination techniques to discern the threat from the background. DRA's system is an extension of technology developed to detect tactical missiles. The system consists of a multi-color, low-cost, commercial off the shelf sensor operating ...

New software development processes depend on accurate specifications; the ability to execute or animate specifications expressed in a lightweight formalism, and the ability to verify properties expressed in that formalism will greatly assist software development. EDAptive Computing, Inc. (ECI) team has designed the Animation and Execution of High Level Specifications (AniSpec) program to address ...

Essential Research Incorporated proposes the development of a high efficiency, metamorphic triplejunction, III-V, space solar cell that will also have significantly higher radiation tolerance. The AM0 one sun efficiency of this AlGaInP/InGaAsP/InGaAs cell will be 31.7%, compared to 28% for the state-of-the-art InGaP/GaAs/Ge cell. Since most of the radiation damage in these cells can be attribut ...

Electrochemical capacitors (supercapacitors) are rechargeable devices which deliver high powers for limited periods. The objective of this proposal is to provide new, low-cost approaches for significantly increasing the power and energy storage of carbon supercapacitors. We do this in two ways: A) We improve power by preparing carbon in the form of a contiguous, conductive foam structure. This is ...
