eutrophication- excessive nutrients in a lake or other body of water, usually caused by runoff of nutrients (animal waste, fertilizers, sewage) from the land, which causes a dense growth of plant life; the decomposition of the plants depletes the supply of oxygen, leading to the death of an...
Effects of Endogenous Factors on Regional Land-Use Carbon Emissions Based on the Grossman Decomposition Model: A Case Study of Zhejiang Province, China The impact of land-use change on greenhouse gas emissions has become a core issue in current studies on global change and carbon cycle. However,...
of molecular chains from the said polymer substances by allowing nitrogen dioxide and/or dinitrogen tetraoxide to do oxidative decomposition reaction in supercritical carbon dioxide, or to treat polymer substances that are at least one of what are selected from polymer substances of addition ...
However, the harsh CO2 splitting conditions, the limited oxygen release kinetics and capacity of metal oxides block further promoted the CO yield and solar-to-fuel energy efficiency. Here, we propose a different carbon cycle assisted by Ni/La2O3 via coupling methane decomposition with ...
If a diagram were drawn showing the different processes that move carbon from one form to another, its main processes would be photosynthesis, respiration, decomposition, natural weathering of rocks, and the combustion of fossil fuels. Photosynthesis. Carbon exists in the atmosphere as the compound...

Moreover, the lab-scale recovery of barium to carbide formation was conducted as the proof-of-concept to validate the coupling process of carbon-to-acetylene with CO2 capture based on Ba looping, resulting in less carbide slag waste and negative carbon emission. The facile co-production of ...
