In-situ DRIFTS Studies on CuNi Catalyst for Ethanol Hydrogen Production

Kumar A., Ashok A., Bhosale R., AlMomani F., Tarlochan F., Qatar University, QA

Ethanol dehydrogenation mechanism was investigated over catalysts containing Cu and Ni metals prepared by solution combustion synthesis. In situ DRIFTS studies were conducted on individual metals (Cu and Ni) as well as on CuNi alloy [...]

Carbon Combustion Synthesis of Lithium Cobaltate

Hobosyan M., Mamyrbaeva Y., Martirosyan K.S., University of Texas at Brownsville, US

We recently developed a novel process Carbon Combustion Synthesis of Oxides (CCSO) to rapidly produce high purity, submicron, porous powders of complex oxides. The crystalline LiCoO2 nanoparticles were synthesized by carbon combustion synthesis, and characterized [...]

Facile in-situ combustion synthesis of TiC reinforced aluminum matrix composites

Nabawy A.M., Khalil K.A., Al-Ahmari A.M., King Saud University, SA

Using high frequency induction heat-assisted combustion synthesis (HFIHACS) as a facile manufacturing methods followed by combustion in tube furnace under inert gas, composites of TiC reinforced aluminum matrix have been in-situ synthesized directly from elemental [...]

Fabrication of Bismuth Trioxide Nanoparticles for Gas-Generators Application

Martirosyan K.S., Wang L., Vicent A., Luss D., University of Houston, US

Nanoenergetic materials release significant amount of energy at a higher rate and have a potential for various military applications. These systems lead to a fast propagation of a reaction front through the solid reactant mixtures. [...]

Flame synthesis of carbon nanotubes using a double-faced wall stagnation flow burner

Woo S.K., Hong Y-T, Kwon O.C., Sungkyunkwan University, KR

The potential of using a double-faced wall stagnation flow burner in mass production of carbon nanotubes was evaluated experimentally and computationally. With nitrogen-diluted premixed ethylene-air flames established on the Ni-coated stainless steel or Ni-sintered, double-faced [...]

Formation of Ceramic Nanopowders and Composites in a Self-Sustaining Reaction Regime

Puszynski J.A., Khachatryan H.L., Maukyan K.V., Kharatyan S.L., South Dakota School of Mines and Technology, US

A combustion synthesis, also called self-propagating high-temperature synthesis, has been found to be an effective and economical production method of advanced ceramic and intermetallic compounds. This method is very suitable for the formation of nonstoichiometric [...]
