Gas-Phase Ozone Oxidation of Monoterpenes: Gaseous and Particulate Products
Atmospheric oxidation of monoterpenes contributes to formation of tropospheric ozone and secondary organic aerosol, but their products are poorly characterized. In this work, we report a series of outdoor smog chamber experiments to investigate both gaseous and particulate products in the ozone oxidation of four monoterpenes: α-pinene, β-pinene, 13-carene, and sabinene. More than ten oxygenated...
متن کاملVapor-phase synthesis of nanoparticles
An overview of methods for preparing nanoparticles in the vapor phase is given, and recent advances are reviewed. Developments in instrumentation for monitoring vapor-phase synthesis of nanoparticles and in modeling these processes are also included. The most important developments relate to improved control and understanding of nanoparticle aggregation and coalescence during synthesis, and to ...
متن کاملFeasibility Study of Vapor-Mist Phase Reaction Lubrication Using A Thioether Liquid
A primary technology barrier preventing the operation of gas turbine engines and aircraft gearboxes at higher temperatures is the inability of currently used liquid lubricants to survive at the desired operating conditions over an extended time period. Current state-of-the-art organic liquid lubricants rapidly degrade at temperatures above 300 °C; hence, another form of lubrication is necessary...
متن کاملThe Gas Phase Oxidation of Acetaldehyde Reaction Mechanism and Kinetics
The mechanism of the low temperature oxidation of gaseous acetaldehyde was investigated in the temperature range of 1 50-400?°C. The minor, intermediate and major products were identified and measured quantitatively by sampling directly into the ionization chamber of an MS10-C2 mass spectrometer from the reactor. The formation of H2O, CO, CO2, HCOOH, H2, HCHO, CH3COOH and CH3OH as the major pro...
متن کاملSynthesis of Polypyrrole Coated SnO2-ZnO Electrospun Nanofibers via Vapor Phase Polymerization Method
This paper reports the synthesis of polypyrrole coated SnO2/ZnOelectrospunnanofibers via vapor phase polymerization method. In order to prepare one dimensional (SnO2- ZnO)/polypyrrole with the core sheath structure, first SnO2-ZnO composite nanofibers were synthesized via electrospinning method followed by adsorption of Fe 3+ on the surface of the SnO2-ZnO nanofibers and finally pyrrole w...
