SiC has exceptionally high thermal conductivity and low linear expansion coefficient to resist thermal distortion, high elastic modulus to resist pressure and bowing distortion. It is lightweight and wear resistant. It also has excellent corrosion resistance and outstanding load bearing characteristics at elevated temperatures. Its hardness is only surpassed by diamond, CBN and boron carbide. As ...

As electronic packaging densities increase, more heat is being generated per unit area. The reliability of electronic components is, therefore, increasingly dependent on the ability to transfer heat. Current chip performance is limited in keeping up with the increased power densities, 30% of which is attributed to packaging materials. The disadvantages of current methods of fabrication of thermal ...

This Phase I SBIR demonstrates the underlying technology required to construct an ultraspectral imager that has the ability to spectrally resolve molecular absorption lines while simultaneously creating a two dimensional spatial mapping. The proposed instrument will have a spectral resolution that is better than 2 cm-1 and two dimensional spatial resolution that exceeds 2 milliradian. Based on Fou ...

Functional gradient materials (FGMs) have a microstructurally graded transition in composition (e.g. zirconia to a nickel based superalloy). The graded transition eliminates problems associated with a discrete interface such as poor mechanical strength and transport losses. They are being actively pursued by the engineering community, particularly in Japan, as a means of taking advantage of two di ...

properties: Intramolecular and intermolecular charge transfers in phthalocyanine molecules can be used as signal generators for information processing and storage; phthalocyanine molecules show an excellent molecular stability resistant to environmental changes and harsh conditions, high thermal stability up to 280¿ C in normal environment and up to 700-800¿ C in vacuum, resistive to B and most ...

We offer an approach to a multiple-order-of-magnitude processing speed/efficiency improvement in vector quantization (VQ) data/image compression, automatic target recognition/classification, and time signal/signature classification. We base our approach on an algorithmic breakthrough, the TABULAR NEAREST-NEIGHBOR ENCODER (TNE), which we discovered and partially developed last year. This algorithm ...

Semiconducting lasers, laser arrays and other diode-laser devices for both military and private sector applications benefit greatly if used in conjunction with isolators capable of preventing reflections from reentering the device. This proposal describes an approach which can be integrated with laser/amplifier semiconducting material system, to produce efficient non-reciprocal magneto-optic isola ...
