ABSTRACT:The reduction of aerodynamic/hydrodynamic noise caused by violent turbulence is of strategic importance to many military systems. These include modern fighter jets, unmanned weapons with sensitive electronics, and surface and underwater vessels. For all these systems, aerodynamic or hydrodynamic noise can produce unacceptable levels of operational loads or acoustic vibrations, or be detri ...

This proposal is for a Phase II program for further development and prototyping of a Development and Run-time Environment for Aviation Mission-tasking and Mission-management (DREAMM) for manned-unmanned teams.Development and modification of the tightly integrated avionics in a combat aircraft is highly technical and currently requires skilled engineers to effect even the most minor changes in syst ...

Fuel cells convert chemical energy in a fuel directly to electrical power. They have several advantages over other energy sources including: highly efficient energy conversion, fuel flexibility, reduced air pollution, reduced greenhouse gas emissions, reduced oil consumption, and expanded use of renewable power. State-of-the-art Solid Oxide Fuel Cells (SOFC) use lanthanum strontium cobalt iron oxi ...

Opportunities exists to use high moment magnetic nanoparticles CoxFe100-x to replace annealing-stabilized high induction -FeCo phase as the primary phase in the currently used soft magnetic materials (e.g. HITPERM). The key to this development is to design advanced nanocomposites containing high moment nanoparticles for small, lightweight passive inductors, by using an innovative cost-effective ...

Lean-burn engines have the potential to provide more efficient and cleaner operation. However, extremely lean mixtures are more difficult to ignite than the near-stoichiometric mixtures used in todays combustion engines. Reliably igniting extremely lean fuel-air mixtures requires more energy be efficiently delivered to the fuel charge than present-day spark ignition systems typically supply. A mor ...

Hyrax Energy, Inc. is the first company to spin-out of the DOEs Great Lakes Bioenergy Research Center (GLBRC) and is the exclusive owner of intellectual property that enables biorefineries based on ionic liquids that that operate at a fraction of the cost and carbon footprint of competing technologies. Ionic liquids are true solvents for cellulose, which promises amongst other things to greatly si ...

The Department of Energy (DOE) has identified the need for tools and technologies to ensure the safety of personnel who carry out decontamination and decommissioning work at unused nuclear facilities. Strippable, fixative coatings with a visual indication of contaminant (e.g., elemental mercury and its ions) capture would improve safety and minimize hazards and waste during the demolition process ...

The storage of industrially generated carbon dioxide (CO2) in deep geologic formations is being seriously evaluated as a method for reducing carbon dioxide emissions to the atmosphere, and CO2 injection is being used for enhanced oil recovery, leaving two thirds of the CO2 stored underground. Reliable and cost-effective monitoring is required to demonstrate that the geologic storage is safe and ...

Problem statement: For low cost manufacturing of high efficiency solar cells and solar modules, manufacturers are ever looking for effective tools to measure the problematic defects and performance variations in their critical processes. Approach to addressing the problem: The light, or laser, beam induced current (LBIC) technique has been used in the laboratory to produce detailed images of the o ...

Li-ion battery calendar and cycle life degrade at elevated temperatures due to processes involving the interaction of electrolyte salt, solvents and battery electrode materials. The major factor impacting automotive Li-Ion battery pack safety is the use of high vapor pressure and low flashpoint carbonate electrolyte solvents. Development of high voltage cathode materials requires new solvents and ...
