Abstract:Hafnium diboride and zirconium diboride have properties that make them ideally suited for plasma containment vessels including high melting point, good creep resistance, high thermal conductivity, good oxidation resistance and good optical emissivity and absorptivity. Although these materials have… more
Abstract:Functional gradient materials (FGMs) have a microstructurally graded transition in composition (e.g. zirconia to a nickel based superalloy). The graded transition eliminates problems associated with a discrete interface such as poor mechanical strength and transport losses. They are being actively… more
Abstract:The proposed program is to develop the use of aqueous biopolymers for the solid freeform fabrication of ceramic components. It will be a collaborative effort between ACR and Battelle PNL. PNL has expertise in colloidal ceramic processing and experience on utilizing biopolymers in ceramic slurries.… more
Abstract:The primary objectives of this Phase I effort are to assess the feasibility of developing a p-channel 2-D MESFET and to determine the extent of the significant reduction in power consumption of integrated circuits which may be achieved by utilizing a complementary 2-D MESFET technology. The new FET… more
Abstract:Advanced Device Technology, Inc. In collaboration with Dartmouth Medical College proposes to develop a portable device to measure parcial pressure of oxygen (PO2) in skin and skeletal muscle using Electron Paramagnetic Resonance (EPR) Oximetry. We will adopt this recently emerging technology to the… more
Abstract:This proposal is focused at testing a new family of intermetallic materials for superior wear resistance in automotive applications due to the self-lubricating potential of the base material at a significant reduction in operating cost and capital investment. The proposed materials are produced by… more
Abstract:THE PRIMARY CONTAMINANTS FROM COMBUSTION PROCESSES ARE PARTICULATES, UNBURNED HYDROCARBONS, CHLORINATED COMPOUNDS, SULFUR OXIDES, NITROGEN OXIDES, AND AMMONIA. AN IMPORTANT ASPECT OF POLLUTION CONTROL STRATEGIES IS THE ABILITY TO HAVE ON-LINE MONITORING OF THE CLEANUP DEVICE. THIS ENSURES… more
Abstract:X-RAY ABSORPTION SPECTROSCOPY (XAS) BASED AT SYNCHROTRON FACILITIES IS AN ESTABLISHED RESEARCH TOOL IN A VARIETY OF FIELDS INCLUDING BIOCHEMISTRY, CATALYSIS, AND MATERIALS SCIENCE. FOR TRACE ANALYSIS, XAS OFFERS IMPORTANT PHASE INFORMATION AS WELL AS ELEMENTAL COMPOSITION. COMMERCIALIZATION WILL… more
Abstract:This Phase I project will develop certain innovations in silicon wafer micromachining, and pulsed-laser deposition, to fabricate arrays of pyroelectric detectors from epitaxial metal-oxide thin films. These pyroelectric materials will be ferroelectric metal-oxides and hence have very large electric… more
Abstract:The flue gases of combustion-type power plants contain small, respirable ash andfume particles which originate from the inorganic species in the fuel. Coalburning power plants, for example, have a notorious reputation for spewing outflue gas particles originating from the mineral mater in the coal.… more
Abstract:FIRES KILL NEARLY 10,000 PEOPLE EACH YEAR IN THE U.S. AND CAUSE NEARLY 300,000 INJURIES AND OVER 6 BILLION DOLLARS IN PROPERTY DAMAGE. THE PER CAPITA LOSS OF LIFE DUE TO FIRES IN THE U.S. IS HIGHER THAN FOR ANY OTHER INDUSTRIAL COUNTRY. CONSEQUENTLY, THERE IS A GREAT NEED FOR ADDITIONAL RESEARCH ON… more
Abstract:Future manufacturing of integrated circuits (IC's), will require analytical instrumentation that can provide on-line process monitoring linked to real time process control. Fourier Transform Infrared (FT-IR) spectroscopy can be effectively utilized to meet this need. As an example, Advanced Fuel… more
Abstract:Improved methods for frozen storage of glycerolized red blood cells (RBCs) are needed both tomeet military and civilian needs in periods of high demand. Existing deglycerolization ssytems are labor intensive and considered "open" systems resulting in a maximum storage of 24hrs following washing. The… more
Abstract:We propose development of a 'smart' optical preprocessor that installs as an integral part of the light gathering optics of first- or second-generation forward looking infrared imaging systems (FLIRs). This optical preprocessor is based on an advanced-art imaging acousto-optic tunable filter (aka,… more
Abstract:The theoretical maximum energy product of intermetallic compounds Nd2Fe14B and Pr2Fe14B is as high as 64 M Oe at room temperature. However, the actual energy product achieved in the laboratory is ~50 M Oe and the best commercial magnets exhibit only ~45 MG Oe. The inability to fabricate magnets with… more
Abstract:Diabetes is widely recognized as one of the leading causes of death and disability. Medical complicdiabetes can cause blindness, heart disease, stroke, kidney failure, nerve damage, and amputations.and Complications Trial researched the effect of intensive treatment on insulin dependent diabetics… more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
