|
 | Eltron Research Inc. has developed multi-component metal oxide catalysts for destruction of volatile organic compounds (VOCs) in air at low temperatures. The goal for this work is to produce a simple, cost-effective technology for reducing the concentration of VOCs in air to acceptable levels before the air is released into the atmosphere or recirculated. Specific applications include ventilated work spaces for spray painting and engine maintenance (degreasing and fuel line ... |

|
 | This Phase I project identified and characterized novel inorganic proton conducting composite membranes which do not require water maintenance systems. These materials can be used as membranes in proton exchange membrane fuel cells as well as a wide variety of hydrogen separation applications. This technology could be of significant economic and technical benefit to the Army and industries by providing low cost, high reliability, high efficiency, low temperature fuel cells ... |

|
| Eltron Research, Inc., is pursuing the rational development of catalysts for direct (reagentless) decomposition of NOx. This is the most economical imaginable approach for post-combustion removal of nitrogen oxides because costs for reagent and reagent delivery (i.e., ducting, etc.) are eliminated, and catalysts demonstrating activity to the present time are inexpensive ($1-$4/lb). The decomposition of nitrogen oxides in simulated exhaust streams over new brownmillerite ... |

|
| This program was directed toward synthesis of two closely related classes of new lithium ion conducting polymer electrolytes which are demonstrating both higher ionic conductivity and improved elastomeric properties over current state-of-the-art polymer electrolytes. The strategy exploited the approach that carbonate oxygens, within the single phase carbonate-siloxane polymer matrix, will facilitate extensive ionic dissociation of introduced lithium salts, and that furthermore elastomeric behavior of the matrix under ambient temperature conditions ... |

|
| This Phase I SBIR program was directed towards the synthesis, characterization, and determination of preferred catalyst compositions for the high-temperature direct (reagentless) decomposition of nitrogen oxides in exhaust streams. Phase I results showed clearly that significant persistent (nontransient) activity (35% removal) for direct deNO(x) (at > 500 deg C) could be attained in helium at space velocities of ^1,000,000 per h (3.6ms residence time) over a brownmillerite catalyst supported on ... |

|
| This investigation was directed towards developing novel ElectroChemical Machining (ECM) technology for the processing of titanium alloys for application in air breathing propulsion systems by Naval Aircraft. The feature of this approach relies upon the application of unique heterogeneous electrolytes consisting of dispersions of electronically conducting particles within an ionically conducting aqueous phase. This resulted in effectively extending the cathode into close proximity to ... |

|
| The project objective was directed towards development and subsequent commercialization, for dual use applications, of a distributed multisite fiber optic chemical sensor technology for achieving the real time monitoring of unsymmetrical dimethylhydrazine (UDMH) and its congeners, monomethylhydrazine (MME) and hydrazine (H) down to the 10 ppb concentration level. Selective detection of hydrazines was performed by monitoring absorbance changes via evanescent wave interaction at the fiber ... |

| This program is addressing the need for diagnostic instrumentation to detect the presence of hidden chemical corrosion occuring at aircraft titanium and aluminum alloys. The approach is being directed towards development of pattern recognition schemes based upon the initial on-line acquisition of electrochemical impedance spectra using Fast Fourier Transform Electrochemical Impedance Spectroscopy (FFTEIS) instrumentation from the suspect corrosion site.
