O3 photochemistry on O3 episode days and non-O3 episode days in Wuhan, Central China
Atmospheric Environment, 2020Abstract Simultaneous field measurements of ozone (O3) and its precursors were conducted at an urban site (Zi Yang, ZY) and a suburban site (Huang Pi, HP) in August 2018 in Wuhan, China. The observation results revealed that the mean levels of nitric oxide (NO), nitrogen dioxide (NO2), carbon monoxide (CO) and non-methane hydrocarbons (NMHCs) were ...

Acta crystallographica. Section C, Crystal structure communications, 2012
The title compound, [Mg(2)(C(12)H(14)O(4))(2)](n), is the first example of an s-block metal adamantanedicarboxylate coordination polymer. The asymmetric unit comprises two crystallographically unique Mg(II) centers and two adamantane-1,3-dicarboxylate ligands. The compound is constructed from a combination of chains of corner-sharing magnesium-centered

Opportunistic routing achieves significant performance gain under lossy wireless links. In this paper, we develop a novel approach that exploits inter-flow network coding in opportunistic routing. A unique feature of our design is that it systematically optimizes end-to-end performance (e.g., total throughput). A key challenge to achieve this goal is a

Treatment of pharmaceutical wastewater containing antibiotics by O3 and O3/H2O2 processes
Chemosphere, 2003Ozonation of three different synthetic pharmaceutical formulation wastewater containing two human antibiotics and a veterinary antibiotic has been studied to enhance the their biodegradability. The effects of pH and initial chemical oxygen demand (COD) value as well as addition of hydrogen peroxide on ozonation process were investigated.

O3 and UV/O3 oxidation of organic constituents of biotreated municipal wastewater
Water Research, 2008Dissolved organic matter (DOM) in the biotreated effluent of a municipal wastewater treatment plant was separated by XAD-8 and XAD-4 resins into four fractions: hydrophobic acids, non-acid hydrophobics, transphilics and hydrophilics. Ozonation with and without ultraviolet (UV) enhancement removed most UV-absorbing substances in the first 30 min ...

Variations of CO and O3 in the troposphere: Evidence of O3 photochemistry
Atmospheric Environment (1967), 1986The possibility of a long term evolution for tropospheric ozone, connected to a rise of anthropogenic releases, raises the question of a human climatic action. In order to bring an experimental confirmation to photochemical theories, continuous CO and O3 measurements were started in November at the Pic du Midi observatory (3000 m altitude in the ...

Gas-Phase Kinetics of O3 + C2H2 and O3 + H2C=CCl2
Journal of Chemical Education, 2000Ozone plays a significant role in the troposphere by oxidizing many organic compounds. While reactions between O3 and saturated hydrocarbons are very slow, reactions between O3 and unsaturated hydrocarbons are sometimes fast enough to be atmospherically significant. This report describes an experiment for the physical chemistry laboratory that measures

The Cl2 photosensitized decomposition of O3: the reactions of ClO and OClO with O3
Journal of Photochemistry, 1979Abstract Cl2 was photolyzed in the temperature range 254 – 296 K with 366 nm radiation in the presence of O3· O3 was removed with quantum yields of 5.8 ± 0.5, 4.0 ± 0.3, 2.9 ± 0.3 and 1.9 ± 0.2 at 24, 10,0 and—21 °C respectively, independent of the initial O3 or Cl2 removal quantum yields were 0.11 ± 0.2 at 24 °C for Cl2 conversions of about 30 ...

Controlled O3 Exposures and Field Observations of O3 Effects in the UK
1997Damage caused by air pollution to conifers in the UK was first recorded by Cohen and Ruston (1912), and it has long been known that one of the most serious effects of air pollution on conifers is increased susceptibility to cold injury and drought (Munch 1933; Lux 1965) including winter desiccation.
