The proposed effort will investigate several nanophotonic structures to engineer the phase and amplitude of an incident optical beam to form a protective surface layer. Dielectric metasurfaces are used to engineer the optical properties of a protective layer on a sub-wavelength scale. Evaluations will be performed on the interactions of the metasurfaces with high energy lasers to form a basis ...

Summit Information Solutions, Inc. (Summit) proposes to use a mature thin film deposition technology, widely adopted by the microelectronics industry, to deposit pinhole-free thin films of copper and silver metal (< 10nm) onto oxide substrates. While there has been some success with using this thin film deposition technique to deposit these films onto metal substrates, a viable, repeatable methodo ...

Through the proposed STTR program, NanoSonic and Virginia Tech will fabricate flexible perovskite solar modules (12 x 12) that are capable of providing conversion efficiencies greater than 20% under AM 1.5G standard solar spectrum, and which demonstrate stability against temperatures up to 50C and relative humidity up to 80%. The photovoltaic market is dominated by crystalline silicon solar panel ...

Chemiresistors are an important class of electronic sensors that detect the presence of analytes/chemicals via a change in the resistance of a sensor element. A typical interdigitated electrode array is deposited onto an insulating substrate with metallic electrodes that have feature sizes in the 5-500 m range. The metal electrodes are typically sputter coated onto the substrate, using lithogra ...

Smart textile technologies with advanced functionalities (e.g., sensing, physical actuation) are being developed for military and civilian applications. These products have, to date, been powered by conventional energy storage systems that can significantly limit the multi-functional aspects of product design. Next generation products are envisioned that rely on integrated energy storage technolog ...

Highly scalable parallel random number generators (RNGs) will be developed, evaluated and implemented for use in high performance computing on thousands of multi-core processors and general purpose graphics processing units. The main contributions are: (a) design and implementation of new parallel test methods that capture the inter-stream correlations exhibited in practice and complement the curr ...

This STTR Phase I project will develop a novel toxic material storage bag with an inner liner capable of decontaminating chemical and biological warfare agents (CBWA’s).. The inner-liner technology would entail adsorption and decomposition of warfare agents without the release of toxic agents, and will result in a storage bag capable of being disposed of in an environmentally safe fashion. The ...

The enormous effort devoted to the data acquisition, signal processing, and automatic recognition of stationary targets has resulted in a generation of synthetic aperture radar (SAR) systems that are meeting the challenge of real-world conditions. However, in a practical battlefield, moving targets may pose a more severe threat than stationary targets. Many high value targets are only vulnerable w ...

NP Photonics proposes to develop a fiber-based, compact, tunable, THz spectroscopic/fingerprinting system that offers ultra-high resolution (< 1 MHz), high sensitivity and room temperature operation over the 1-3 THz range. This proposed system will provide high resolution molecular fingerprint information by leveraging NP Photonics high power and narrow linewidth fiber-based THz source, which is b ...

Metron, Inc. and Stanford University propose to design, develop, test and demonstrate topological data analytic algorithms to analyze hyperspectral imagery. We propose to adapt the topological data analytic techniques, including Stanford’s successful Mapper algorithm, to the hyperspectral imagery domain. Using these algorithms we will identify topological and geometric features and properties ...
