THIS PHASE I PROPOSAL IS DESIGNED TO EXAMINE CLOSELY AN INNOVATIVE CONCEPT FOR RECOVERING THE RESOURCE POTENTIAL OF ORGANIC MUNICIPAL AND INDUSTRIAL WASTE MATERIALS. THE WASTE MATERIALS WILL BE SUBSTITUTED FOR TOPSOIL IN A NOVEL SYSTEM FOR GROWING GRASS SODS. THE NEW GRASS GROWING SYSTEMAPPEARS CAPABLE OF PRODUCING A SOD CROP IN AS LITTLE AS 6 WEEKS AS COMPARED TO 1 TO 2 YEARS FOR SOD PRODUCED IN ...

SINGLE CRYSTAL UREA HAS BEEN DEMONSTRATED TO BE A USEFUL NONLINEAR OPTICAL MATERIAL. ITS MOST PROMISING APPLICATION IS AS THE BASIS OF THE FIRST PRACTICAL, ALL SOLID STATE, BROADLY TUNABLE LASER. CURRENTLY, HOWEVER, ITS USE IS SEVERELY RESTRICTED BECAUSE NO ONE HAS YET RELIABLY GROWN LARGE, OPTICAL GRADE MATERIAL. PAST CRYSTAL GROWTH ATTEMPTSHAVE CONCENTRATED ON GROWING ALONG THE 110 DIRECTION WIT ...

THE RESEARCH EFFORT IS DIRECTED TOWARDS DETERMING THE TECHNICAL FEASIBILITY OF MORPHOLOGICALLY INVARIENT ELECTRODE/SOLID POLYMER ELECTROLYTE (SPE) JUNCTIONS FOR LONGCYCLE LIFE ELECTROCHEMICAL CELLS. ALKALI ION CONDUCTING SPES TO BE USED IN THIS PROGRAM WILL INCLUDE THOSE BASED UPON POLY(ETHYLENE OXIDE) AND THE POLYPHOSPHAZENES. NOVEL SECONDARY ELECTRODES WILL INCLUDE THE LITHIUM INTERCALATING MATE ...

TECHNICAL EFFORT IS DIRECTED TOWARDS DETERMING THE FEASIBILITY OF AN ELECTROCHEMICALLY REVERSIBLE LIQUID NEGATIVE ACTIVE MATERIAL CONSISTING OF LITHIUM DISSOLVED IN LIQUID AMMONIA TO GIVE A NOVEL SOLVATED ELECTRON SECONDARY LITHIUM ELECTRODE. CONTAINMENT OF THE ACTIVE MATERIAL FROM DIRECT CONTACT TO THE LIQUID NON-AQUEOUS ELECTROLYTE IS REALIZED VIA USE OF A LITHIUM INTERCALATED ELECTRONICALLY CON ...

COMMERCIAL TISSUE CULTURE PROPAGATION OF PLANT CULTIVARS IS NOW LIMITED TO SPECIALTY CROPS BECAUSE OF THE HIGH UNIT COSTOF PLANTS SO PROPAGATED. THIS COST IS THE COMBINED EFFECT OF THE LABOR INTENSIVE NATURE OF MANUAL TISSUE TRANSFER WHETHER FOR MEDIUM RENEWAL OR CHANGE AND LOW MULTIPLICATION RATE OF THE CULTURE METHOD USED. THE ROOTING MEDIUM MODULE NOW WIDELY USED AS A FINAL MEDIUM FOR ROOTING O ...

IONICS RESEARCH INC. (IRI) HAS DETERMINED THAT UNCOATED CAPILLARY COLUMNS CAN BE USED TO CONCENTRATE ORGANICS FROM WATER. THE METHOD IS EXCEEDINGLY SIMPLE AND RAPID (10 MINUTES PER 100 ML), YET EFFECTIVE. IRI PLANS TO INVESTIGATE THE POTENTIAL OF THIS TECHNIQUE FOR THE DEVELOPMENT OF AN INSTRUMENT SUITABLE FOR THA NALYSIS OF ORGANICS AT THE PART-PER-TRILLION LEVEL IN WATER AND WASTEWATER. SUCH AN ...

THIS PROJECT WILL TRY TO DEMONSTRATE A METHOD OF INTERNAL TEMPERATURE COMPENSATION FOR BONDED RARE-EARTH PERMANENT MAGNETS, PARTICULARLY FOR THOSE BASED ON ND-FE-B. THE STRONG TEMPERATURE DEPENDENCE OF THE SPONTANEOUS MAGNETIZATION (M) OF THE LATTER IN THE TYPICAL USE RANGE, O C TO +150 C, IS A PROBLEM IN MANY APPLICATIONS. (MS DROPS QUICKLY AS T INCREASES.) THIS CANNOT BE REMEDIED BY ALLOYING A H ...

THIS PROPOSAL IS CONCERNED WITH THE ECONOMIC REMOVAL OF HYDROGEN SULFIDE, A TOXIC MATERIAL, FROM SOUR NATURAL GAS AND PETROLEUM PRODUCTS. THE CURRENT STATUS OF H2S PROCESSING IS REVIEWED. THE CHEMISTRY OF SULFUR AND SULFIDE IN AQUEOUS SOLUTIONS AND PRELIMINARY WORK ALREADY CARRIED OUT IN THE CONTINUOUS ELECTROLYSIS OF H2S TO YIELD HYDROGEN AND SULFUR ARE BRIEFLYDISCUSSED. THE ESTIMATED ECONOMIC GA ...

OVER THE LAST SEVERAL YEARS, THE EPA HAS DEVOTED MAJOR EF- FORTS TO IDENTIFY AND DOCUMENT THE MAGNITUDE OF THE RISKS OFENVIRONMENTAL POLLUTION DUE TO LEAKING UDERGROUND STORAGE TANKS (UST). IN APRIL 1987, THE EPA PUBLISHED THE PROPOSED REGULATIONS FOR THE OWNERS AND OPERATORS OF UST, WHICH ARE EXPECTED TO BE FINALIZEDD IN EARLY 1988. THESE REGULATIONS INCLUDE REQUIREMENTS FOR TANK TIGHTNESS TESTS, ...

HUMAN-BASED EXPERTISE TO DIAGNOSE AND REPAIR ELECTRO-MECHANICAL HARDWARE SYSTEMS IS GAINED ONLY THROUGH LENGTHY EXPERIENCE, BUT THIS EXPERTISE VANISHES WITH THE INDIVIDUAL. THIS RESEARCH EXPLORES METHODS TO CAPTURE AND EMBED THIS EXPERTISE TO PROVIDE HARDWARE SELF-DIAGNOSTICS THROUGH THE USE OF ALTERABLE ON-COMPONENT MICRO-DATA BASES STORED ON AN ADD-ON "DATA TEMPLATE". THIS DATA TEMPLATE CONTAINS ...
