China has considerable coal resources. Benefiting from the widespread distribution of coal measures and the inter-sedimentary development of coal bed, dark shale, and fine-grained tight sandstone in coal measures, China has a geological environment and material basis favorable for the co-occurrence of a variety of coal gases. With such a huge reservoir of coal gases, including gases such as coa...

Most models of double-barred galaxies suggest that a molecular gas component is crucial for maintaining long-lived nuclear bars. We have undertaken a CO survey in an attempt to determine the gas content of these systems and to locate double barred galaxies with strong CO emission that could be candidates for high resolution mapping. We observed ten galaxies in CO J=2−1 and J=3−2 and did not det...

The molecular gas in (some) early type galaxies holds important clues to the history and the future of these galaxies. In pursuit of these clues we have used the BIMA millimeter array to map CO emission in the giant elliptical galaxies NGC 83 and NGC 2320 and to search for CO emission from the S0 galaxy NGC 5838. We also present V and R images of NGC 83 and NGC 2320 which trace their dust distr...

We present 300 resolution maps of CO, its isotopologues, and HCN from in the center of Maffei 2. The J 1⁄4 1Y0 rotational lines of CO, CO, CO and HCN, and the J 1⁄4 2Y1 lines of CO and CO were observed with the Owens Valley Radio Observatory (OVRO) and Berkeley-Illinois-Maryland Association (BIMA) arrays. The lower opacity CO isotopologues give more reliable constraints on H2 column densities a...

We report the first detection of CO (1!0) emission from a submillimeter-selected galaxy, using the Green Bank Telescope. We identify the line in the spectrum of SMM J13120+4242 as a broad emission feature at z 1⁄4 3:408, with VFWHM 1⁄4 1040 190 km s . If the observed CO (1!0) line profile arises from a single object and not several merging objects, then the CO (4!3)/CO (1!0) brightness temperat...

Multi-walled carbon nanotube (MWCNT) film has been fabricated onto Pt-patterned alumina substrates using the chemical vapor deposition method for NH(3) gas sensing applications. The MWCNT-based sensor is sensitive to NH(3) gas at room temperature. Nanoclusters of Co catalysts have been sputtered on the surface of the MWCNT film to enhance gas sensitivity with respect to unfunctionalized CNT fil...

We present interferometric observations of CO(1–0) emission in the elliptical galaxy NGC759 with an angular resolution of 3 . ′′1×2 . ′′3 (990 × 735 pc at a distance of 66Mpc). NGC759 contains 2.4× 109 M of molecular gas. Most of the gas is confined to a small circumnuclear ring with a radius of 650 pc and with an inclination of 40◦. The maximum gas surface density in the ring is 750M pc−2. Alt...

CO(2) subcutaneous emphysema is one of the complications of laparoscopic surgery using CO(2) gas. During laparoscopic surgery, CO(2) gas can spread to the entire body surface through the subcutaneous tissue layer. Extensive CO(2) subcutaneous emphysema results in hypercarbia and acute respiratory acidosis. Hypercarbia and acidosis can lead to decreased cardiac contractility and arrhythmia. A cl...

An experimental study of the oxidation of CO in exhaust gas from a motorcycle has been carried out using plasma chemical reactions in a pulsed corona discharge. In the process, some main parameters, such as the initial CO concentration, amplitude and frequency of pulses, residence time, reactor volume, and relative humidity (RH), as well as their effects on CO removal characteristics, were inve...

The iron-based catalyst was prepared by a microemulsion method. The composition of the final nanosized iron catalyst, in terms of the atomic ratio, contains 100Fe/4Cu/2K. The experimental techniques of XRD, BET, TEM, and TPR were used to study the phase, structure, and morphology of the catalyst. Fischer-Tropsch synthesis (FTS) reaction test was performed in a fixed bed reactor under pressure o...
