Application of Direct Analysis in Real Time-Mass Spectrometry (DART-MS) to the Study of Gas–Surface Heterogeneous Reactions: Focus on Ozone and PAHs

14-Apr-2015 | Shouming Zhou; Matthew W. Forbes; Jonathan P. D. Abbatt, Analytical Chemistry, 2015

A novel analytical method is presented whereby Direct Analysis in Real Time-Mass Spectrometry (DART-MS) is applied to the study of gas–surface heterogeneous reactions. To illustrate the capabilities of the approach, the kinetics of a well-studied reaction of surface-bound polycyclic aromatic ...

Isotopocule analysis of biologically produced nitrous oxide in various environments

13-Apr-2015 | Sakae Toyoda, Naohiro Yoshida, Keisuke Koba, Mass Spectrometry Reviews, 2015

Natural abundance ratios of isotopocules, molecules that have the same chemical constitution and configuration, but that only differ in isotope substitution, retain a record of a compound's origin and reactions. A method to measure isotopocule ratios of nitrous oxide (N2O) has been established ...

Reaction of OH radical and ozone with methyl salicylate – a DFT study

10-Apr-2015 | A. Mano Priya, Lakshmipathi Senthilkumar, Journal of Physical Organic Chemistry, 2015

A theoretical study on the reaction mechanism of methyl salicylate (MeSA), a green leaf volatile organic compound with OH radical and ozone, has been carried out using density functional theory methods using B3LYP, M06‐2X and MPW1K functionals with 6‐311++G(d,p) basis set. The atmospheric ...

Continuous process of the vacuum ultraviolet- (VUV-) photochemical oxidation of thiophene in the gas phase

08-Apr-2015 | Haingo L. Andriampanarivo; Martin Köhler; Juan López Gejo; Thomas Betzwieser; Benny C. Y. Poon; Po Lock Yue; Solofon ..., Photochemical & Photobiological Sciences, 2015

Thiophene was taken as a model compound for investigations on the efficiency of a continuous process of the vacuum-ultraviolet- (VUV-) photochemically initiated oxidation and mineralization of sulfur containing organic compounds in the gas phase. In the presence of molecular oxygen, atomic oxygen ...

Gas-phase rate coefficients of the reaction of ozone with four sesquiterpenes at 295 +/- 2 K

08-Apr-2015 | Stefanie Richters; Hartmut Herrmann; Torsten Berndt, Physical Chemistry Chemical Physics, 2015

The rate coefficients of the reaction of ozone with the four atmospherically relevant sesquiterpenes β-caryophyllene, α-humulene, α-cedrene and isolongifolene were investigated at 295 ± 2 K and atmospheric pressure by at least two independent experimental investigations for each reaction. ...

[Perspective] Defining the epoch we live in

03-Apr-2015 | William F. Ruddiman; Erle C. Ellis; Jed O. Kaplan; Dorian Q. Fuller, Science , 2015

Human alterations of Earth's environments are pervasive. Visible changes include the built environment, conversion of forests and grasslands to agriculture, algal blooms, smog, and the siltation of dams and estuaries. Less obvious transformations include increases in ozone, carbon dioxide (CO2), ...

Hierarchical line-defect patterns in wrinkled surfaces

01-Apr-2015 | Bernhard A. Glatz; Moritz Tebbe; Badr Kaoui; Roland Aichele; Christian Kuttner; Andreas E. Schedl; Hans-Werner Schmi ..., Soft Matter, 2015

We demonstrate a novel approach for controlling the formation of line-defects in wrinkling patterns by introducing step-like changes in the Young's modulus of elastomeric substrates supporting thin, stiff layers. Wrinkles are formed upon treating the poly(dimethylsiloxane) (PDMS) substrates by ...

Reaction between CH3O2 and BrO Radicals: A New Source of Upper Troposphere Lower Stratosphere Hydroxyl Radicals

27-Mar-2015 | Dudley E. Shallcross; Kimberley E. Leather; Asan Bacak; Ping Xiao; Edmond P. F. Lee; Maggie Ng; Daniel K. W. Mok; Jo ..., Journal of Physical Chemistry A, 2015

Over the last two decades it has emerged that measured hydroxyl radical levels in the upper troposphere are often underestimated by models, leading to the assertion that there are missing sources. Here we report laboratory studies of the kinetics and products of the reaction between CH3O2 and BrO ...
