| The purpose of this study was to determine the feasibility of Naval tactical and non-tactical use of alternative fuels as a way to reduce dependence on foreign oil and harmful air pollutants. The alternative fuels are divided into two classes: biofuels and manufactured fuels. The biofuels are the simple alcohols (methanol, ethanol, and butanol) that can be produced from biomass (various crops, grasses, trees, etc.) and biodiesel that is produced ... |

| Two types of novel actuators that are powered by high-energy-density fuels (hydrogen, methanol, or formic acid fuel combined with air or oxygen) have been experimentally demonstrated in this program. The first type uses a carbon nanotube electrode that simultaneously functions as a muscle, a fuel cell electrode and a supercapacitor electrode. The result is a muscle that converts the chemical energy in the fuel to electrical energy and can use ... |

| Over the past two decades, several fuels have been tested in pulsed detonation engines (PDEs) throughout the world. This research focuses on developing a baseline set of ignition and detonation performance measures for six distinct fuels in air: Hydrogen, ethylene, propane, aviation gasoline (avgas), JP-8, and Fischer-Tropsch JP-8 (S-8). To quantify the ignition and detonation performance, four parameters are examined: Ignition time, deflagration- to-detonation transition (DDT) time, DDT distance, and ... |

| Four and a half years after freeing Iraqi citizens from a ruthless dictatorship, the country is still mired in poverty, corruption and insurgent violence. These conditions fuel a sprawling, decades-old shadow economy manipulated by elements of organized crime, militias, and insurgents to fund attacks on Coalition forces, infrastructure and innocent Iraqi civilians. The shadow economy is also used extensively by the poor and women for subsistence living. The combined effect ... |

| A new method to achieve steady-state and dynamic tracking desorption of organic compounds from activated carbon was developed and tested with a bench-scale system. Activated carbon fiber cloth (ACFC) was used to adsorb methyl ethyl ketone (MEK) from air streams. Direct electrothermal heating was then used to desorb the vapor to generate select vapor concentrations at 500 ppmv and 5000 ppmv in air. Dynamic-tracking desorption was also achieved with carefully ... |
