Reducing Bacterial Contamination in Fuel Ethanol Fermentations by Ozone Treatment of Uncooked Corn Mash

21-May-2015 | Mary L. Rasmussen; Jacek A. Koziel; Jay-lin Jane; Anthony L. Pometto, III, Journal of Agricultural and Food Chemistry, 2015

Ozonation of uncooked corn mash from the POET BPX process was investigated as a potential disinfection method for reducing bacterial contamination prior to ethanol fermentation. Corn mash (200 g) was prepared from POET ground corn and POET corn slurry and was ozonated in 250 mL polypropylene ...

Stabilization of the Simplest Criegee Intermediate from the Reaction between Ozone and Ethylene: A High-Level Quantum Chemical and Kinetic Analysis of Ozonolysis

21-May-2015 | Thanh Lam Nguyen; Hyunwoo Lee; Devin A. Matthews; Michael C. McCarthy; John F. Stanton, Journal of Physical Chemistry A, 2015

The fraction of the collisionally stabilized Criegee species CH2OO produced from the ozonolysis of ethylene is calculated using a two-dimensional (E, J)-grained master equation technique and semiclassical transition-state theory based on the potential energy surface obtained from high-accuracy ...

Characteristics of Back Corona Discharge in a Honeycomb Catalyst and Its Application for Treatment of Volatile Organic Compounds

15-May-2015 | Fada Feng; Yanyan Zheng; Xinjun Shen; Qinzhen Zheng; Shaolong Dai; Xuming Zhang; Yifan Huang; Zhen Liu; Keping Yan, Environmental Science & Technology, 2015

The main technical challenges for the treatment of volatile organic compounds (VOCs) with plasma-assisted catalysis in industrial applications are large volume plasma generation under atmospheric pressure, byproduct control, and aerosol collection. To solve these problems, a back corona discharge ...

Source Apportionment of the Anthropogenic Increment to Ozone, Formaldehyde, and Nitrogen Dioxide by the Path-Integral Method in a 3D Model

15-May-2015 | Alan M. Dunker; Bonyoung Koo; Greg Yarwood, Environmental Science & Technology, 2015

The anthropogenic increment of a species is the difference in concentration between a base-case simulation with all emissions included and a background simulation without the anthropogenic emissions. The Path-Integral Method (PIM) is a new technique that can determine the contributions of ...

Combustion Processes as a Source of High Levels of Indoor Hydroxyl Radicals through the Photolysis of Nitrous Acid

15-May-2015 | V. Bartolomei; E. Gomez Alvarez; J. Wittmer; S. Tlili; R. Strekowski; B. Temime-Roussel; E. Quivet; H. Wortham; C. Z ..., Environmental Science & Technology, 2015

Hydroxyl radicals (OH) are known to control the oxidative capacity of the atmosphere but their influence on reactivity within indoor environments is believed to be of little importance. Atmospheric direct sources of OH include the photolysis of ozone and nitrous acid (HONO) and the ozonolysis of ...

IJERPH, Vol. 12, Pages 5061-5075: Effect of Naturally Occurring Ozone Air Pollution Episodes on Pulmonary Oxidative Stress and Inflammation

12-May-2015 | Pirozzi, Cheryl ; Sturrock, Anne ; Weng, Hsin-Yi ; Greene, Tom ; Scholand, Mary Beth; Kanner, Richard ; III, Robert ..., International Journal of Environmental Research and Public Health, 2015

This study aimed to determine if naturally occurring episodes of ozone air pollution in the Salt Lake Valley in Utah, USA, during the summer are associated with increased pulmonary inflammation and oxidative stress, increased respiratory symptoms, and decreased lung function in individuals with ...

Simultaneous Absorption of NOx and SO2 Using Magnesia Slurry Combined with Ozone Oxidation

12-May-2015 | Chenglang Sun; Nan Zhao; Haiqiang Wang; Zhongbiao Wu, Energy & Fuels, 2015

To achieve simultaneous removal of NOx and SO2 in flue gas, an effective technology combined with ozone oxidation was explored in this paper. The simulated flue gas was initially oxidized by ozone (O3), turning NO into NO2 or N2O5, and then absorbed by alkaline slurries to achieve simultaneous ...

Highly efficient quenching of tris(2,2[prime or minute]-bipyridyl)ruthenium(II) electrochemiluminescence by ozone using formaldehyde, methylglyoxal, and glyoxalate as co-reactants and its application to ozone sensing

07-May-2015 | Ying Gao; Xiaoyun Liu; Wenjing Qi; Wenyue Gao; Yunhui Li; Guobao Xu, Analyst, 2015

Most electrochemiluminescence (ECL) systems require high concentrations of quencher to totally quench ECL. In this study, we found that ozone can quench tris(2,2′-bipyridyl)ruthenium(ii) ECL using formaldehyde, methylglyoxal, or glyoxalate as co-reactants at a glassy carbon electrode with ...

Kinetic study of MOCVD of NiO films from bis‐(ethylcyclopentadienyl) nickel

07-May-2015 | A. S. Kondrateva, M. Mishin, A. Shakhmin, M. Baryshnikova, S. E. Alexandrov, physica status solidi (c), 2015

Abstract NiO films were grown by metal‐organic chemical vapor deposition (MOCVD) using bis‐(ethylcyclopentadienyl) nickel [(EtCp)2Ni] and oxygen or ozone as precursors. The kinetic regularities of MOCVD processes were experimentally studied in the deposition temperature range 600‐820 K for the ...
