the optimization model for evaluating regional and global effects of greenhouse gases reductionpolicies named merge is an actively usable tool for studying some aspects of the problem of climate change.it is first of all destined for the quantitative estimation of emission trajectories and results of applyingabatement measures. in the paper, the emphasis is on the adaptation of the integrated a...

The aim of this study is to investigate the problems caused by discharge of polluted air from tunnels into the environment with a specific focus on residential areas. In city tunnels, portal or stacks, pollutant management is a big challenge. Nowadays, air quality management, particularly in urban tunnels, is considered as a part of the ventilation system design. The goal is to see the environm...

Graphene is a monolayer carbon atoms discovered in the recent past which has inspired researchers in a wide range of applications. It has a surface area as high as 2630 m2/g and thermal conductivity value of 3000 W/mK-1 at room temperature. It is chemically the most reactive form of carbon with one carbon atom exposed to reaction from each side. Stable dispersion of graphene was achieved using ...

Greenhouse gas emission reduction has become the responsibility and consensus of all mankind’s development, the way of non-sustainable land use results in a lot of greenhouse gas emissions in the context of low-carbon economy. On the basis of revealing impact of land use on carbon emissions and status of carbon emissions, this paper proposes the regulation proposals of land use based on low-car...

The merit of various kinds of carbon nanotubes as field electron emission cathode materials has been studied. The field electron emission characteristics of electrophoretically deposited films of single walled carbon nanotubes, multiwalled carbon nanotubes of diameter between 10 and 20 and .50 nm and carbon nanofibres with diameters between 200 and 600 nm were investigated. Results of the measu...

The geometrical structures and field emission properties of pristine and N-doped capped (5,5) single-walled carbon nanotubes have been investigated using first-principles density-functional theory. The structures of N-doped carbon nanotubes are stable under field emission conditions. The calculated work function of N-doped carbon nanotube decreases drastically when compared with pristine carbon...

This study attempts to discuss the relationship between land use spatial distribution structure and energy-related carbon emission intensity in Guangdong during 1996-2008. We quantized the spatial distribution structure of five land use types including agricultural land, industrial land, residential and commercial land, traffic land, and other land through applying spatial Lorenz curve and Gini...

Agricultural Sector Analysis on Greenhouse Gas Emission Mitigation in the United States. (December 2000) Uwe Schneider, M.Ag., Humboldt University, Berlin; M.S., Texas A&M University Chair of Advisory Committee: Dr. Bruce A. McCarl This dissertation analyzes the economic potential of agriculture to participate in greenhouse gas emission mitigation efforts. Major agricultural mitigation strategi...

An inductively coupled plasma atomic emission spectrometer is used to detect carbon-containing compounds following separation by high-performance liquid chromatography. A calcium form ligand exchange column with distilled and deionized water as the mobile phase is used to separate carbohydrates. The eluting species are detected by monitoring the carbon atomic emission line at 193.09 nm. The mas...

Multi-walled carbon nanotubes (MWNT) have been synthesized by chemical vapour decomposition (CVD) of acetylene over Rare Earth (RE) based AB2(DyNi2) alloy hydride catalyst. The as-grown carbon nanotubes were purified by acid and heat treatments and characterized using powder X-ray diffraction, Scanning Electron Microscopy, Transmission Electron Microscopy, Thermo Gravimetric Analysis and Raman ...
