Three vanadium-based catalysts were used to remove high concentrations of nitrogen oxides, and the catalysts’ performance de-NOx anti-H2O under NOx investigated. The V-Mo-W/TiO2 tested 1500 mL/min gas flow (GHSV = 500 h−1, 2.4% NO2, 4.78% NH3, 13% O2, 4% H2O, 5% CO2) characterized by BET, SEM, EDS, XRD, XPS, H2-TPR, NH3-TPD; then, their physical chemical properties analyzed. results showed that...
The objective of this study was to test whether a glycosaminoglycan component of the surface glycocalyx layer is a fluid shear stress sensor on endothelial cells (ECs). Because enhanced nitric oxide (NO) production in response to fluid shear stress is a characteristic and physiologically important response of ECs, we evaluated NOx (NO2- and NO3-) production in response to fluid shear stress aft...
[1] The Pacific Exploration of Asian Continental Emission Phase A (PEACE-A) aircraft measurement campaign was conducted over the western Pacific in January 2002. Correlations of carbon monoxide (CO) with carbon dioxide (CO2) and back trajectories are used to identify plumes strongly affected by Asian continental emissions. DCO/DCO2 ratios (i.e., linear regression slopes of CO-CO2) in the plumes...
NO and NO2, collectively denoted NOx, are generated in the Earth’s atmosphere mainly from the photochemistry of biogenic nitrogen-containing gases whereas on Mars they form through the oxidation of products derived from ionospheric dissociation of N2. NOx disappears from both atmospheres when acids form from further oxidation and deposit to the surface. We show that peroxynitric acid (PNA), HO2...
