THE PROPOSED WORK INVOLVES APPLICATION OF SUPPORTED MOLTEN SALT CATALYSIS TO THE CATALYTIC ENDOTHERMIC DEHYDROGENATION OF HIGH ENERGY-DENSITY AVIATION FUELS. THE CATALYSTS OF INTEREST ARE HETEROGENEOUSLY DISPERSED PLATINUM AND NICKEL, TO BE USED ALONE OR IN BIMETALLIC CLUSTERS. THE MOLTEN SALTS TO BE USED INCLUDE BINARY AND TERNARY EUTECTICS INVOLVING ALKALI METAL CHLORIDES AND HYDROXIDES. THE SUP ...

N/A

BASED ON WORK PUBLISHED IN 1981 BY JAYARAMAN, MCPARLAND, MILLER, AND TS'O (PNAS 78 1537 (1981) WE PROPOSE THAT A NOVEL TYPE OF ULTRA-BROAD-SPECTRUM ANTIBACTERIAL AGENT MAY BE POSSIBLE. SUCH AN AGENT WOULD BIND TO A KEY RNA SEQUENCEWHICH IS EXPECTED TO BE HYPERSENSITIVE TO INACTIVATION ONLY IN PROCARYOTES. IF SUCH AN ANTIBACTERIAL AGENT PROVES FEASIBLE THEN THE BASIC APPROACH MAY ALSO ALLOW RATIONA ...

THE NEED FOR SOPHISTICATED DATABASE MANAGEMENT SUPPORT IN NAVY COMMAND AND CONTROL SYSTEMS CONTINUES TO GROW. HOWEVER, CONVENTIONAL DATABASE MANAGEMENT STRATEGIES AND TECHNIQUES ARE NOT CURRENTLY MEETING THE UNIQUE NEEDS OF NAVY DECISION SUPPORT SYSTEMS, WHICH REQUIRE EXTENDED CAPABILITIES FOR HANDLING UNCONVENTIONAL DATA FORMATS AND TEMPORAL INFORMATION. IN THIS PROPOSAL, AQUIDNECK MANAGEMENT ASS ...

ENZYME-CATALYZED REACTIONS OFFER ATTRACTIVE PROCEDURES FOR PREPARING PURE ENANTIOMERS, INCLUDING PHARMACEUTICALS, INSECTICIDES, AND HERBICIDES. DESPITE A PLETHORA OF ATTRACTIVE FEATURES, ENZYMES HAVE NOT BEEN WIDELY ACCEPTED AS ROUTINE CATALYSTS FOR THE PREPARATION OF PURE ENANTIOMERS. ONE REASON FOR THIS IS THAT MANY ENZYMES REQUIRE COFACTORS CALLED COENZYMES TO BE CATALYTICALLY ACTIVE. COENZYMES ...

MEMBRANE-BASED GAS SEPARATIONS ARE ATTRACTIVE BECAUSE OF THEIR INHERENT ENERGY EFFICIENCY AND LOW OPERATING COSTS. HOWEVER, METHODS CURRENTLY AVAILABLE FOR HYDROGEN SEPARATIONS ARE COSTLY AND INEFFICIENT. POLYMERIC MEMBRANESNOW IN USE ARE CAPABLE OF ONLY LIMITED SELECTIVITY, WHICH LEAVES SUBSTANTIAL AMOUNTS OF IMPURITIES IN THE HYDROGEN STREAM. THOSE MEMBRANES ARE ALSO HEAT-SENSITIVE; CONSEQUENTLY ...

REVERSE OSMOSIS (RO) IS A PROMISING NEW PROCESS FOR SHIPBOARD PRODUCTION OF POTABLE WATER FROM SEAWATER. HOWEVER, CURRENT RO SYSTEMS SUFFER FROM TWO PROBLEMS: 1) FOULING CAUSED BY THE FEED STREAMS,AND 2) CHEMICAL DEGRADATION OF THE RO MEMBRANES DUE TO DISINFECTANTS (USUALLY CHLORINE) USED IN THE FEED STREAM. EXTENSIVE PRETREATMENT IS THUS NEEDED WHEN CURRENT RO SYSTEMS ARE USED ON SEAWATER. THUS, ...

THE NAVY HAS A NEED FOR A RELIABLE, COMPACT, AND ENERGY-EFFICIENT COMPRESSED-AIR DEHYDRATION SYSTEM. WE PROPOSE TO DEVELOP SUCH A SYSTEM BASED ON SYNTHETIC MEMBRANE TECHNOLOGY. PRELIMINARY EXPERIMENTAL AND DESIGN STUDIES AT BEND RESEARCH INDICATE THAT IT IS POSSIBLE TO DEVELOP MEMBRANES AND MEMBRANE MODULES DESIGNED SPECIFICALLY FOR THIS APPLICATION--RESULTING IN A SYSTEM THAT CONTAINS ONLY ABOUT ...

THE REMOVAL OF ORGANIC CONTAMINANTS FROM WASTEWATERS IS A KEY ASPECT OF THIS COUNTRY'S POLLUTION-CONTROL EFFORT. HOWEVER, CONVENTIONAL TREATMENT TRAINS ARE COMPLICATED AND EXPENSIVE. IN THIS PROPOSED PROGRAM, WE WILL INITIATE DEVELOPMENT OF A MEMBRANE-BASED PROCESS, CALLED PERVAPORATION, FOR THE REMOVAL AND RECOVERY OF ORGANIC POLLUTANTS FROM INDUSTRIAL WASTEWATERS. THIS PROCESS HAS THE CAPABILITY ...

MEMBRANE FOULING, THE LONG-TERM IRREVERSIBLE DECLINE IN PERMEATE FLUX, GREATLY LIMITS THE APPLICATION OF ENERGY-EFFICIENT MEMBRANES TO INDUSTRIAL PROCESSING NEEDS. THE ECONOMICS OF MANY CURRENT MEMBRANE PROCESSES WOULD BE IMPROVED AND THE INTRODUCTION OF NEW MEMBRANE APPLICATIONS WOULD BE ACCELERATED IF EXISTING MEMBRANES COULD BE MODIFIEDTO EXHIBIT (1) HIGHER PERMEATE FLUXES WITHOUT ATTENDANT LOS ...
