A facile method is developed for the large-scale growth of hierarchical transition-metal (Cu, Fe, and Ni) vanadate nanosheets on corresponding metal mesh as supports. The hierarchical transition-metal vanadate nanosheets were in situ grown on the metal meshes through an orientational etching process and simultaneous nucleation and growth process. Interestingly, the morphologies of the vanadate ...

Air pollution due to anthropogenic activities is currently one of the most important problems faced worldwide. This study aimed determine associations between air quality and spatial, meteorological, factors while evaluating using stress index (ASI) daily (DAQx) scale. The annual mean levels CO, NOx, O3, PM 2.5, PM10 SO2 in region were 718.6, 39.5, 44.4, 25.5, 51.3, 9.9 ?g/m3, respectively. Whi...

When burning fuel in grate furnaces, supplying the right amount of air to them is as important method supply. In a furnace with fixed grate, supply primary determined by distribution supplied stream over time, and movable said involves along active length grate. The need account for attributable complex processes that occur during combustion process. paper describes experimental studies aimed a...

With the increasing demand for electricity due to economic boom, there is an excessive production of emissions that natural processes cannot cope with. Fortunately, are various technological solutions capturing harmful substances from produced emissions. However, European Union aims prevent formation in process industrial itself. In order achieve this, it necessary reconcile interests individua...

Emissions in East Asia for 1993 by administrative units and source types are estimated to support regional emission assessments and transport modeling studies. Total emission of SOx, NOx, soil NOx, N2O, and NH3 are 24,150 kton/year, 12,610 kton/year, 1,963 kton/year, 908kton/year, and 8,263 kton/year, respectively. China’s emission contribution is the highest for every species. The area sources...

Wet scrubbing combined with ozone oxidation has become a promising technology for simultaneous removal of SO2 and NOx in exhaust gas. In this paper, a new 20-species, 76-step detailed kinetic mechanism was proposed between O3 and NOx. The concentration of N2O5 was measured using an in-situ IR spectrometer. The numerical evaluation results kept good pace with both the public experiment results a...

Title of Document: AIR POLLUTANT CONCENTRATIONS AND TRENDS OVER THE EASTERN U.S. AND CHINA: AIRCRAFT MEASUREMENTS AND NUMERICAL SIMULATIONS Hao He, Doctor of Philosophy, 2012 Directed By: Professor Russell R. Dickerson Department of Atmospheric and Oceanic Science In the last several decades, efforts have been made to mitigate air pollution all around the world. With surface observations showin...

The effects of SO2 and NH3 on secondary organic aerosol formation have rarely been investigated together, while the interactive effects between inorganic and organic species under highly complex pollution conditions remain uncertain. Here we studied the effects of SO2 and NH3 on secondary aerosol formation in the photooxidation system of toluene/NOx in the presence or absence of Al2O3 seed aero...

Currently there are still many power plants using fossil fuels, including oil, gas and coal to produce electricity. The problem recently received by developing countries, Indonesia, is environmental degradation due CO, SO2 NOx emissions. Co-burning of biomass with in most countries one the economical technologies available today for significant pollutant reduction. This study tested combined co...

We perform the first long-term (>1 year) continuous adjoint simulations with a global atmospheric chemistryetransport model focusing on population exposure to fine particulate matter (PM2.5) and associated risk of early death. Sensitivities relevant to intercontinental and high-altitude PM pollution are calculated with particular application to aircraft emissions. Specifically, the sensitivitie...
