Measurement of Thermal Properties of Suspensions of Nanoparticles in Engine Oil

Khan Mohammadi S., Etemad S.Gh., Thibault J., Isfahan University of Technology, CA

Nanofluids refer to new kinds of engineering materials which are prepared by dispersing fine nanometer sized particles (smaller than 100 nm) in a base fluid. It has been recognized in the past decade that nanofluids [...]

Environmentally Friendly Production of Unconventional Natural Gas Resources

Haut R.C., Burnett D., Williams T., Houston Advanced Research Center, US

Clean burning natural gas begins with producing the gas in an environmentally friendly manner. Industry has made great strides in protecting the environment while increasing natural gas production in the U.S. Producers, however, still face [...]

Phase Stabilized and Enhanced PtCu3/C oxygen reduction electrocatalysts via Au galvanic displacement

Liu Z., Huang D., Koh S., Yu C., More K.L., Allard Jr. L.F., Strasser P., University of Houston, US

We reported here that the enhanced electrocatalytic oxygen reduction activity of PtCu3/C catalysts was stabilized using Au galvanic displacement of Cu in PtCu3/C. The results showed that mass activities decreased by 24 and 29%, and [...]

Nickel oxide hollow nano-fiber electrodes for electrochemical capacitors

Machida S., Tsutsumi H., Yamaguchi University, JP

Morphology of electroactive materials in electrodes affects their electrochemical performance and capacity of energy storage devices. New architectures (3D) for electrodes and cells will overcome the traditional electrodes’ problems. However, preparation of 3D electrodes needs [...]

Promoting the activity of LiFePO4 (olivine) cathode of Li-ion battery by supramolecular complexes with single walled carbon nanotubes

Kavan L., Exnar I., Graetzel M., J. Heyrovsky Institute of Physical Chemistry, CZ

The amphiphilic Ru-bipyridine complex, NaRu(4-carboxylic acid-4’-carboxylate-2, 2’bipyridine)(4,4’-dinonyl-2,2’bipyridine)(NCS)2 can be used as a surfactant for solubilization of single walled carbon nanotubes (SWNTs) in acetonitrile-t-butanol mixture. The Ru-complex represents a redox functionality of 3.5 V vs. Li/Li+, [...]

High lithium ion storage capacity of CO annealed titania nanotube arrays

Liu D., Zhang Y., Cao G., University of Washington, US

Highly ordered titania nanotube (TNT) arrays were fabricated by anodic oxidation of titanium foil followed by CO annealing. The lithium-ion intercalation capacities of the as-prepared sample was studied and found to be improved a lot [...]

A Novel Architecture for Micro Fuel Cells

Moghaddam S., Pengwang E., Lin K., Masel R.I., Shannon M.A., UIUC, US

We report, for the first time, development of a fully integrated millimeter-scale (331 mm3) fuel cell-based power generator with a completely passive control system. Fabrication of this unique power source was enabled through development of [...]

Non bacterial way of production of alcohols and biofuel

Gorakavi P.K., Gorakavi P.K., University college of Technology, Osmania University, IN

Biofuel which is currently being produced through a variety of bacterial uses can be replaced by a much more faster and economical process of production which involves production in laboratory with ot using metabolism. This [...]

Renewable Energy Strategies for non-RPS States

Hill B., Fleming S., Georgia Institute of Technology, US

Oral presentation. Renewable energy can succeed in non-RPS states. Second generation renewable fuels offer a viable market beachhead for the introduction and development of renewable energy businesses in non-RPS states, particularly the Southeastern United States. [...]

Operating Conditions of Binary Mixtures of Biomass Wastes in Spouted Bed Contactors for Using Energy

San José M.J., Alvarez S., López L.B., Garcia I., Universidad del Pais Vasco, ES

Due to the increasing costs of fossil fuels, interest has grown in the use of renewable energy. Spouted bed technology is suitable for the thermal treatment of biomass by combustion and by pyrolysis. Therefore, it [...]
