LOW DENSITY MICROCELLULAR MATERIALS (LDMMS) ARE CARBON- OR SILICON-BASED POROUS SOLIDS WITH HIGH SPECIFIC SURFACE AREAS. THESE MATERIALS HAVE BEEN DEVELOPED EXTENSIVELY OVER THE LAST DECADE, AND THEY ...

THE HEAT LOADS ON BOARD MILITARY AIRCRAFT HAVE HISTORICALLY INCREASED WITH HIGHER MAXIMUM SPEEDS AND GREATER USE OF HEAT GENERATING ELECTRONICS. THE HEAT LOAD IS DISSIPATED BY HEATING THE FUEL PRIOR T ...

NITROGEN OXIDES (NO AND NO2 OR NOX) ARE AMONG THE MOST PERVASIVE AND DIFFICULT EMISSIONS TO CONTROL. ALTHOUGH THE DECOMPOSITION OF THE MAJOR SPECIES (NO) IS THERMODYNAMICALLY FAVORED, THERE ARE NO COM ...

NEW REGULATIONS ARE FORCING THE CONTROL OF VERY DILUTE VOLATILE ORGANIC COMPOUND (VOC) EMISSIONS. ALTHOUGH CATALYTIC INCINERATION IS INCREASINGLY THE TECHNOLOGY OF CHOICE, ENERGY AND CATALYST COSTS RI ...

POROUS INORGANIC MEMBRANES CAN BE USED AT HIGH TEMPERATURES, AND HAVE HIGH FLUXES, MECHANICAL STRENGTH, AND CHEMICAL STABILITY. HOWEVER, COMMERCIALLY AVAILABLE INORGANIC MEMBRANES HAVE LARGE PORES (>4 ...

NITROGEN OXIDES (NO AND NO2 OR NOX) ARE AMONG THE MOST PERVASIVE AND DIFFICULT EMISSIONS TO CONTROL. CURRENTLY, THERE ARE NO COMMERCIAL CATALYTIC PROCESSES CAPABLE OF DECOMPOSING NOX WITHOUT THE ADDIT ...

Aircraft designed for flight in the Mach 3-6 range must incorporate active cooling in the turbo-ramjet propulsion system. The required cooling can be provided by endothermic reactions of the fuel prio ...

Leaking underground fuel storage tanks must be rapidly detected to minimize cleanup costs. TDA research, (TDA) has identified a class of tracer compounds that allow the rapid detection of leaks. The t ...

AUTOMOTIVE CATALYTIC CONVERTERS ARE QUITE EFFICIENT ONCE THEY REACH OPERATING TEMPERATURE, TYPICALLY DESTROYING OVER 98% OF THE INCOMING HYDROCARBONS (HCS) AND CARBON MONOXIDE (CO). HOWEVER, UP TO 80% ...

SURFACTANT-BASED SEPARATION PROCESSES OFFER HIGH SELECTIVITY AND ENERGY EFFICIENCY, AND IMPROVED METHODS TO EFFICIENTLY FORM OR DISRUPT SURFACTANT-INDUCED STRUCTURES WOULD FURTHER IMPROVE PROCESS ECON ...
