A PROGRAM TO DEVELOP ELECTROCHROMIC DEVICES CAPABLE OF FAST TRANSMISSIVE TO REFLECTIVE OPTICAL SWITCHING IS PROPOSED. THESE DEVICES WOULD BE USED FOR OPTICAL HARDENING IN THE WAVELENGTH RANGE FROM 0.615 MICROMWTERS. OPTICAL SWITCHING ELEMENTS BASED ON SINGLE CRYSTAL LAYERS OR EPITAXIAL FILMS OF THE METAL DICHALOCOGENIDES ZRS(2) AND HF(2) WOULD BE DEVELOPED. WE PROPOSE TO INTERCALATE SINGLE CRYSTAL ...

"Spire proposes to develop high-efficiency filterless silicon-based multi-color photodiode arrays suitable for spectroscopy and imaging applications in the UV to near-IR bands. The innovation, patented by Spire, is the use of a thin filmsilicon-on-insulator (SOI) structure in the active device region, which enables fabrication of wavelength-selective photodiodes. In these devices, the long cut-o ...

"ALTAIR Center proposes to develop a miniature, cost-effective fiber optic sensor array for detection of toxic heavy metal ions. The main detection principle is based on dual measurement of both absorption and fluorescence employing thin films ofporphyrin/polymer membrane. In Phase I of the project we studied the luminescence compounds and demonstrated that thin films of porphyrin-based membranes ...

"There is a need for a cost-effective technology for producing III-nitride substrates for fabrication of high efficiency and high power radar transmit/receive modules, as well as opto-electronic devices. The problems with the current technology offabricating III-nitride based devices on thin films grown on foreign substrates, such as sapphire or SiC, are the plethora of defects associated with th ...

"Mg alloys reinforced with high modulus graphite fibers have nearly 1.5 times the specific stiffness of beryllium. Since the EKV sunshade is a stiffness critical application, a sunshade manufactured from graphite fiber reinforced magnesium could weigh athird less than the current Be design. Using MMCC's net-shape Advanced Pressure Infiltration Casting (APICT) process, the sunshade would cost hal ...

"This Phase I study proposes to address the objective of configuring a Guidance, Navigation and Control (GN&C) system suitable for missile defense interceptors which realizes order-of-magnitude reductions in mass, volume and cost relative to current GN&Csystems. These improvements will be sought through a combination of conceptual advances and use of components which benefit from cost reductions ...

"A novel method of micro-mixing by inducing a low frequency resonant sonic vibration (LFRSV) in the fluid medium results in the increased rate of energy dissipation per unit mass of the fluid, allowing rapid and efficient dispersion of solids, gases, andimmiscible liquids. This enhanced way of achieving micro mixing, can be used for dispersing nano particles in making gel propellants. Rheologica ...

"This proposal describes an all-optical 32x32 low-loss cross-connect switch based on periodically-poled gratings in an electro-optic waveguide substrate. The gratings are arranged between parallel waveguide channels and serve to produce coupling of thedesired wavelength from a given input channel to the desired output channel. Because these gratings are produced electro-optically, they may be swit ...

"Eikos Inc. proposes to develop a nanocomposite with high dielectric constant (K), low loss, and high breakdown strength, to meet the design objectives of high energy density (HED) capacitors. This technology offers substantial improvements in energystorage by lowering size, weight, and system cost applicable to a wide array of future and existing systems. In the proposed Phase I program, we will ...

"Physical Sciences Inc. proposes the fabrication of novel composite cathode materials for lithium ion batteries based on vanadium pentoxide and conducting polymers. These composite electrodes are expected to utilize the polyvalent intercalation capabilitiesof V2O5, allowing access to all four of the available valence states in the active material. Currently, the high capacity available in V2O5 can ...
