We report on single-dish radio CO observations towards the inter-galactic medium (IGM) of the Stephan’s Quintet (hereafter SQ) compact group of galaxies. Extremely bright mid-IR H2 rotational line emission (L(H2) ≈ 1035 W) from warm (102−3 K) molecular gas has been detected by the Spitzer satellite in the kpcscale shock created by a collision between a galaxy, NGC 7318b, and NGC 7319’s tidal ar...

methanol steam reforming plays a pivotal role to produce hydrogen for fuel cell systems in a low temperature range. to accomplish higher methanol conversion and lower co production, the reaction was catalyzed by cuznfe mixed oxides. various ratios of fe and cu/zn were coprecipitated in differential method to optimize the cuznfe structure. the sample containing 45cu50zn5fe (wt. %) revealed its m...

A newly designed gas-sampling device using end-tidal CO(2) to separate dead space gas from alveolar gas was evaluated in 12 mechanically ventilated patients. For that purpose, CO(2)-controlled sampling was compared with mixed expiratory sampling. Alveolar sampling valves were easily controlled via CO(2) concentration. Concentrations of four volatile substances were determined in the expired and...

We have investigated the effects of sputtering Ar gas pressure on magnetic and magneto-optical properties in compositionally modulated Co/Pd thin films. The samples were prepared by dc magnetron sputtering from 2-in.-diam Co and Pd targets by alternately exposing the substrates to targets. Sputtering Ar gas pressure was varied from 2 to 30 mTorr. All samples had same bilayer thicknesses compose...

The growth and on-site bioremediation potential of an isolated thermal- and CO₂-tolerant mutant strain, Chlorella sp. MTF-7, were investigated. The Chlorella sp. MTF-7 cultures were directly aerated with the flue gas generated from coke oven of a steel plant. The biomass concentration, growth rate and lipid content of Chlorella sp. MTF-7 cultured in an outdoor 50-L photobioreactor for 6 days wa...

The Flash Ironmaking Technology being developed at the University of Utah is aimed at producing iron directly from iron oxide concentrate. In this technology, the concentrate is reduced by H2 and CO gas mixtures formed from the partial oxidation of natural gas in a flash reactor. Natural gas represents an economically and environmentally superior reductant/fuel for the flash ironmaking. The rat...

vanadium phosphorus oxides (vpo) has been applied as a heterogeneous catalyst in gas phase oxidation reactions and its application is very limited in liquid phase. in this study a series of cobalt-doped vanadium phosphorus oxides (vpo-co) catalysts with different loading of co (0.01-1.0 mol ratio of co/v) were prepared. oxidation of benzyl alcohol was studied in the liquid phase over vpo and vp...
