binding analysis of C 1score-level spectra as well. Density functional theory (DFT) calculations elucidate a possible reaction route for the observed CO2dissociation process with an activation energy barrier (Ea) of 0.58 eV on account of the nonuniform distribution of charge transfers between th...
摘要: Carbon dioxide concentration in the air is another important factor for plant growth. The CO2 concentration in the open air varies daily. On a sunny day the CO2level is fairly constant around 300 to...DOI: 10.1007/978-94-010-0583-8_7 ...
根据第一段“The atmospheric level of carbon dioxide (CO2)—a gas that is great at trapping heat, contributing to climate change-is almost double what it was prior to the Industrial Revolution. This presents a challenge to researchers attempting to design artificial trees or other methods of ...
The volcanic activity level here is considered low, with the last eruption 1,900 years ago. 据认为,这里的火山活动水平很低,上一次火山喷发是1900年前。 The Orca plant, which cost $10-15 million to build, can suck...
by regulation of H2O2 level [17]. In terms of the influence of atmospheric CO2 concentration on the composition of ecosystems, the increase in CO2 levels is expected to cause climate change, which in turn will affect all aspects of biodiversity. Thus, one in five plant species is threatened ...
By using measured and calculated data, an experimental assessment of the relationships between the COconcentration levels and the number of occupants and their level of satisfaction was performed. The indoor air quality level in the hall, evaluated by means of the experimental data, was compared ...
The terrestrial carbon sink slows the accumulation of carbon dioxide (CO2) in the atmosphere by absorbing roughly 30% of anthropogenic CO2 emissions, but varies greatly from year to year. The resulting variations in the atmospheric CO2 growth rate (CGR)
In light of reducing the atmospheric CO2 level to mitigate its effect on climate change, the combination of new air-capture technologies and large offshore storage reservoirs, supplemented by carbon neutral renewable energy, could address both of these engineering and public policy concerns. Because ...

1), is characterized by the appropriate level of pedogenesis. The detrital carbonates are mostly absent in paleosol samples, whereas authigenic carbonates are still preserved (Supplementary Fig. 2). Before sampling, we trenched the soil profile (>1 m deep) to avoid contamination of regolith, ...
