Ammonia Decomposition over Ni Supported on Multi-Wall Carbon Nanotubes: Effect of Surface Functional Groups

Zhang H., Alhamed Y., Kojima Y., Al-Zahrani A., Idriss H., Petrov L., Daous M., King Abdulaziz University, SA

Functional groups on the Multi-Wall Carbon Nanotubes (MWCNTs) surfaces play an important role in anchoring metal ions. Transition metals such as Fe, Co, Ni supported on MWCNTs with surface carboxyl groups have demonstrated an excellent [...]

Hydrogen Generation from Thermochemical Water-Splitting Using Core Shell Ni-Ferrite/Y2O3 Nanoparticles

Amar V.S., Shende R.V., South Dakota School of Mines & Technology, US

During thermochemical water-splitting process for hydrogen generation,ferritenanoparticles undergo significant grain growth that reduces their surface area and affect the porous morphology. Consequently, hydrogen volume generation diminishes with increase in thermochemical cycles. In order to mitigate [...]

Measuring Degradation Processes of Model Coatings Related to Bioenergy Applications

Dixon M.C., Oom A., Q-Sense a Division of Biolin Scientific, US

Degradation mechanisms are relevant to a wide variety of applications including the bioenergy, biomaterial, semiconductor, and detergent industries. Therefore, it is of interest to study these mechanisms, for example, to better tailor formulations for enzymatic [...]

PRV Induction for Fuel Efficiency and Improvement

Meyer J., PRV Performance, US

PRV PERFORMANCE has developed and patented a pintle-regulated Venturi (PRV) air/fuel induction system for automobiles that premixes fuel and air with minimum pumping loss, resulting in a higher intake pressure and a substantial increase in [...]

Next Generation Nanospring-Enhanced Catalytic Converters

Corti G., Cantrell T., Beaux M., McIlroy D.N., Norton M.G., GoNano Technologies, Inc., US

Air pollution generated from automobile emissions is an area of general concern because of the environmental impact associated with such emissions and the growth in the world vehicle fleet. Significant developments in automotive catalytic converters [...]

Kaulfersch E., Rzepka S., Michel B., Fraunhofer ENAS, DE

The paper aims to introduce ‘Clean Sky’, the largest European aeronautics research programme that will radically improve the impact of air transport on the environment while strengthening and securing aeronautics industry’s competitiveness. The results of [...]

Geospatial Analysis and Optimization of Fleet Logistics to Exploit Alternative Fuels and Advanced Transportation Technologies

Sparks W., Nationl Renewable Energy Laboratory, US

Today's fleet managers are faced with new challenges posed by government mandates and private-sector goals that include reducing petroleum use, reducing greenhouse gas (GHG) emissions, and—for federal and other government fleets—complying with alternative-fuel mandates. Choosing [...]

Molybdenum Dioxide: A Reforming Catalyst for Fuel Flexible Fuel Cells

Norton M.G., Marin-Flores O., Turba T.F., Ha S., Breit J., Washington State University, US

Molybdenum dioxide has been shown to be a very active catalyst for the partial oxidation of a Jet A fuel surrogate (n-dodecane). It not only shows a high oxidation activity towards long-chain hydrocarbons, it also [...]

Propagation and Emissions of Ammonia-substituted Hydrogen/Air Flames

Lee J-H., Lee S.I., Lee J-H., Lee S.I., Kwon O.C., Sungkyunkwan University, KR

In order to evaluate the potential of partial ammonia (NH3) substitution to improve the safety of hydrogen (H2) use in general and the performance of internal combustion engines in particular, the propagation, development of surface [...]
