Acetylene fermentation is a rare metabolism that was previously reported as being unique to Pelobacter acetylenicus Here, we report the genome sequence of Pelobacter sp. strain SFB93, an acetylene-fermenting bacterium isolated from sediments collected in San Francisco Bay, CA.

A novel composite material based on carbon nanofibers (CNF) grown on sintered metal fibers (SMFInconel) filter was investigated for its favorable properties as catalytic support. The CNF were formed directly over the SMFInconel by thermal (650 8C) chemical vapor deposition of ethane–hydrogen mixture. The CNF/SMFInconel composite consists of metal fibers entangled by CNF network of microns thick...

Doping of zinc with silver, palladium, and gold was found to increase reactivity towards carbon tetrachloride in water. Commercial zinc dust, cryochemically prepared zinc metal particles (SMAD nanoparticles), and zinc dust pressed into pellets (mechanically activated zinc) were employed. Reduction products detected were methane, ethylene, acetylene, and other hydrocarbons along with products of...

The growth mechanism of hydrocarbons in ionizing environments, such as the interstellar medium (ISM), and some combustion conditions remains incompletely understood. Ab initio molecular dynamics (AIMD) simulations and molecular beam vacuum-UV (VUV) photoionization mass spectrometry experiments were performed to understand the ion-molecule growth mechanism of small acetylene clusters (up to hexa...

Hydrogenation of oils might be considered as the largest reaction in the edible oil industry. The reaction consists of the addition of hydrogen at the double bounds of fatty acids. Although for some reasons this might be considered a desirable reaction but for some others it might create problems in the food and nutrition chain circle due to the formation of saturated and trans fatty acids. Soy...

Nanosized CuO-CeO2, CuO-Fe2O3, CuO-CeO2-Al2O3 and CuO-Fe2O3-CeO2-Al2O3 were prepared by co-precipitation and wet impregnation techniques and were used for Catalytic decomposition of acetylene to produce carbon nanotubes (CNTs). Weight gain technique was used to follow up the catalytic reactions. The results revealed that catalyst chemical composition, catalytic temperature, acetylene flow rate ...
