The transition to alternative fuels and vehicles presents many challenges that require long-range strategic thought and planning. Fuel producers must make expensive infrastructure decisions about which fuels to support years before they are sold. Vehicle producers must commit to new drivetrains on a similar long-range schedule. Whichever technologies prevail, hydrogen fuel cell, PHEV, BEV or bi...

In this paper, the silicon-containing sulfonated polystyrene/acrylate–ionic liquid (Si-SPS/A–IL)hybrid membranes was prepared to obtain the proton exchange membrane (PEM) materials withhigh methanol barrier and good selectivity. The Si-SPS/A–IL hybrid membranes characterized asthe function of IL to evaluate their potential as PEMs in direct methanol fuel cells (DMFCs).Fourdifferent Hybrid mater...

In Part III of our study on alternative aviation fuels, we present a comprehensive database modeled speciation data consisting seven hydrocarbons varying molecular structure and 26 conventional fuels. The is obtained from the DLR atmospheric high temperature flow reactor with coupled beam mass spectrometry (MBMS) detection system (Part-I). chemical reactivity these real liquid fuels investigate...

INVESTIGATION OF LOW COST SUBSTRATES APPROACHES FOR III-V SOLAR CELLS Marlene Lydia Lichty Old Dominion University, 2017 Director: Dr. Christopher G. Bailey With the need for cleaner energy sources, which can displace fossil fuel, the solar cell industry is of particular interest due to the abundancy of the Sun. Silicon currently dominates terrestrial applications, but efficiency improvements h...

There has been a continuous increase in automotive electric power usage. Future projections show no sign of it decreasing. Therefore, the automotive industry has a need to either improve the current 12 Volt automotive electrical system or move to a higher voltage vehicle electric system. Both of these choices are likely to increase cost of the system. Performance improvements will be needed to ...

Considerable effort is being made to reduce the primary energy consumption in buildings. As part of this effort, fuel cell systems are attracting attention as a new/renewable energy systems for several reasons: (i) distributed generation system; (ii) combined heat and power system; and (iii) availability of various sources of hydrogen in the future. Therefore, this study aimed to develop an eco...

Cook stoves that produce biochar as well as heat for cooking could help mitigate indoor air pollution from cooking fires and could enhance local soils, while their potential reductions in carbon (C) emissions and increases in soil C sequestration could offer access to C market financing. We use system dynamics modeling to (i) investigate the climate change impact of prototype and refined biocha...

-Theoretical and experimental studies dealing with the spray ignition phenomena are reviewed. Two major topics covered are external-source ignition of liquid fuel sprays and spontaneous spray ignition. Experimental and theoretical investigations of external-source ignition of sprays employing different configurations are discussed first. Three major topics included here are: (i) ignition of qui...
