Carboxydothermus hydrogenoformans is a thermophilic strictly anaerobic bacterium that catalyses the water gas shift reaction, the conversion of carbon monoxide with water to molecular hydrogen and carbon dioxide. The thermodynamically favorable growth temperature, compared to existing industrial catalytic processes, makes this organism an interesting alternative for production of cheap hydrogen...

Replacement of methane with carbon dioxide in hydrate has been proposed as a strategy for geologic sequestration of carbon dioxide (CO(2)) and/or production of methane (CH(4)) from natural hydrate deposits. This replacement strategy requires a better understanding of the thermodynamic characteristics of binary mixtures of CH(4) and CO(2) hydrate (CH(4)-CO(2) mixed hydrates), as well as thermoph...

We examine the physical conditions of the molecular gas in the extremely red object (ERO), HR10 (J164502+4626.4, or [HR94] 10) at z = 1.44, as constrained by the recent detection of CO J + 1 → J, J = 1, 4 lines. The line ratios of such widely spaced CO transitions are extremely sensitive probes of gas excitation; in the case of the HR 10, they provide a rare opportunity to study the state of th...

Conserved protein antigens among serotypes of group A Streptococcus pyogenes (GAS) have been focused for vaccine development because of the diversity of GAS serotypes and risks of autoimmunity post-GAS infection. Precise delineation of protective immune response to each of GAS antigens is critical for vaccine efficacy and safety. We recently reported that immunization with SrtA of GAS provides ...

We examine the physical conditions of the molecular gas in the extremely red object (ERO), HR10 (J164502+4626.4, or [HR94] 10) at z = 1.44, as constrained by the recent detection of CO J + 1 → J, J = 1, 4 lines. The line ratios of such widely spaced CO transitions are very sensitive probes of gas excitation; in the case of HR10, they provide a rare opportunity to study the state of H2 gas in a ...

We present CO(1-0) and CO(2-1) maps of the LINER galaxy NGC 7217, obtained with the IRAM interferometer, at 2.4 ′′ ×1.9 ′′ and 1.2 ′′ ×0.8 ′′ resolution respectively. The nuclear ring (at r = 12 ′′ = 0.8kpc) dominates the CO maps, and has a remarkable sharp surface density gradient at its inner edge. The latter is the site of the stellar/Hα ring, while the CO emission ring extends farther or is...

Using the IRAM 30m telescope, we report the detection of the CO(3–2), CO(4–3), CO(5–4) and CO(6– 5) lines in the gravitational lensed submm galaxy SMMJ16359+6612 at z = 2.5. The CO lines have a double peak profile in all transitions. From a Gaussian decomposition of the spectra we show that the CO line ratios, and therefore the underlying physical conditions of the gas, are similar for the blue...

In this paper, oscillatory changes in the conductance of catalyst-doped SnO2 semiconductor materials in the presence of CO gas are investigated. The sensors with various transducing structures of ceramic tubes (Taguchi structure), co-axial Pt coils and substrates with deposited interdigital electrodes are compared. The results show that catalysts in the sensing materials and the sensor’s operat...

We present CO(1–0) and CO(2–1) line emission maps of the barred spiral active galaxy HE 1029-1831 (z = 0.0403) obtained with the IRAM Plateau de Bure Interferometer (PdBI) and in part by the Berkeley-Illinois-Maryland Association (BIMA) observatory. The CO emission is well associated with the optical bar and extended along it. The FWHM of the CO emission is estimated to be ∼(6 ± 2) kpc. The CO ...
