Catalytic Dehydrogenation of Ethane over Mn Oxide Supported on Zeolite Chabazite
<p>A new class of Mn-containing zeolites prepared by incipient wetness impregnation (IWI) have been found to catalyze the ethane dehydrogenation reaction with high selectivity (98%+). Preparation by IWI leads to the formation of Mn<sub>2</sub>O<sub>3</sub> nanoparticles on the external surface of the zeolite crystals and herein is shown that the primary active sites for the reaction are located on the surface of these particles. Propane dehydrogenation is also successfully catalyzed by this catalyst. Other Mn-zeolites (MFI and BEA) also have high reactivity and selectivity towards light alkane dehydrogenation.</p>

Data for: Intercomparison of commercial analyzers for atmospheric ethane and methane observations
<p>Methane (CH<sub>4</sub>) is a strong greenhouse gas that has become the focus of climate mitigation policies in recent years. Ethane / methane ratios can be used to identify and partition the different sources of methane, especially in areas with natural gas mixed with biogenic methane emissions, such as cities. We assessed the precision, accuracy, and selectivity of three commercially available laser-based analyzers that have been marketed as measuring instantaneous dry mole fractions of methane and ethane in ambient air. The Aerodyne SuperDUAL instrument performed best of the three instruments but it requires expertise to operate and space for the large footprint. The Aeris Mira Ultra LDS analyzer also performed well for the price point and small footprint but required characterization of the water vapor dependence of reported concentrations and careful setup for use. The Picarro G2210-i precisely measured methane but it did not detect the 10 ppbv increases in ambient ethane detected by the other two instruments when sampling a plume of incompletely combusted natural gas. For long-term tower deployments or those with large mobile laboratories, the Aerodyne SuperDUAL provides the best precision for methane and ethane. For smaller mobile platforms, the Aeris MIRA is a more compact analyzer, and with careful use, can quantify thermogenic methane sources to sufficient precision for short term deployments in urban or oil and gas areas. We weighed the advantages of each instrument, including size, power requirement, ease of use on mobile platforms, and expertise needed to operate the instrument, and we recommend the Aerodyne SuperDUAL or the Aeris MIRA Ultra LDS depending on the situation.</p>

Cartesian coordinates and rate constants obtained in "Radical Addition and H Abstraction Reactions in Ethane, Ethylene and Acetylene: A Gateway for Ethyl and Vinyl Bearing Molecules in the Interstellar Medium"
<p>Set of cartesian coordinates for reactants, pre-reactant complexes, transition states and products for the reactions presented in the manuscript "Radical Addition and H Abstraction Reactions in Ethane, Ethylene and Acetylene: A Gateway for Ethyl and Vinyl Bearing Molecules in the Interstellar Medium". </p> <p>The energy level employed in the optimisation was UMN15-D3BJ/def2-TZVP using a grid=ultrafine and the dispersion correction parameters recommended in Goerigk et al 2017 (https://pubs.rsc.org/en/content/articlelanding/2017/cp/c7cp04913g), all geometries and energies were obtained using Gaussian16 interfaced to ChemShell. </p> <p>Edit: The comment line of every structure includes its electronic energy (in Eh) and the Zero Point Vibrational Energy (in Eh).</p> <p>Edit: Additionally we included the reaction rate constants obtained with the instanton method at the level of theory mentioned above. These values serve as data behind the figure for the article. The first column of the rate constant file correspond to 1000/T in 1/K whereas the second column present the rate constant in s<sup>-1</sup></p> <p> </p>

Methane and Ethane Observations for Boston, MA, 2012-2020
This dataset provides the hourly average of continuous atmospheric measurements of methane (CH4) from two urban sites and three boundary sites in and around Boston, Massachusetts, U.S., from September 2012-May 2020, measured with Picarro cavity ring down spectrometers (CRDS). Five-minute average atmospheric measurements of ethane (C2H6) and methane at Copley Square in Boston, MA, are also provided, with ethane measured with a laser spectrometer and methane measured with a Picarro CRDS. Background CH4 concentrations for the urban sites were determined using Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model trajectories at the boundary of the study region based on measurements at three boundary sites and wind direction from the North American Mesoscale Forecast System (NAM) 12-kilometer meteorology.
