We report iron-containing mixed-oxide nanocomposites as highly effective redox materials for thermochemical CO2 splitting and methane partial oxidation in a cyclic redox scheme, where methane was introduced as an oxygen "sink" to promote the reduction of the redox materials followed by reoxidation through CO2 splitting. Up to 96% syngas selectivity in the methane partial oxidation step and clos...

Cloud computing provides a flexible infrastructure for IT industries to run their High Performance Computing (HPC) applications. Cloud providers deliver such computing infrastructures through a set of data centers called a cloud federation. The data centers of a cloud federation are usually distributed over the world. The profit of cloud providers strongly depends on the cost of energy consumpt...

Issues on climate change have been recognized as serious challenges for regional sustainable development both at a global and local level. Given the background that most of the artificial carbon emissions are resulted from the energy consumption sector and the energy is also the key element resource for economic development, this paper investigated the relationship between CO2 emission, fossil ...

Nowadays biodiesel is receiving more attention as a most important renewable energy for using in diesel engines. Inthis research, the application of Response Surface Methodology (RSM) was highlighted to investigate the effects of biodiesel-diesel blends (B0, B20, B50 and B100), engine operating parameters (engine load and  speed) on CO2 emission of a diesel engine. The experiments were conducte...

We use observed CO2:CO correlations in Asian outflow from the TRACE-P aircraft campaign (February-April, 2001), together with a 3-D global chemical transport model (GEOS-CHEM), to constrain specific components of the East Asian CO2 budget including, in particular, Chinese emissions. The CO2/CO emission ratio varies with the source of CO2 (different combustion types vs. the terrestrial biosphere...

the purpose of this paper is to investigate causality relationship between emission of carbon dioxide, the level of national income and energy consumption in iran consumption of fuel fossil as an input of production or as a final consumption which produces significant amount of pollution such as green house gases in the world. c02 emission is the most important green – house gases which has the...

Ocean uptake of anthropogenic CO2 reduces pH and saturation state of calcium carbonate materials of seawater, which could reduce the calcification rate of some marine organisms, triggering a negative feedback on the growth of atmospheric CO2. We quantify the effect of this CO2-calcification feedback by conducting a series of Earth system model simulations that incorporate different parameteriza...

The carbon emissions has attracts great concerns in engineering technology researches. The decomposition analysis technology has been popular in the study on influencing factors of industrial carbon emissions (ICE). The change of industries’s CO2 emissions from the three main industries in China over the period 1980-2011 based on the logarithmic mean divisia index (LMDI) method has been carried...
