BEIJING, Feb. 2 (Xinhua) -- Chinese scientists have analyzed data from the country's carbon satellite and created the first global carbon dioxide distribution diagrams. The diagrams aim to provide satellite data support to research on climate change and carbon emissions, the Chinese Academy of Sci...
The molecule is symmetrical and nonpolar. The triple point of pure CO2 occurs at −56.6 °C and 518 kPa (Fig. 1). As a gas, carbon dioxide is clear, colorless, and odorless. Carbon Dioxide, Fig. 1 Phase diagram for pure carbon dioxide Full size image ...
The specific volume of carbon dioxide ( v /dm 3 kg 1 ) was measured by varying the pressure ( p ) 1–600bar and the temperature ( T ) at each pressure in the range of 273–1000K. Using these v , ρ =1/ v , p , and T quantities taken from the literature, phase diagrams ...
These carbonate rocks are recycled at plate boundaries and decarbonation reactions return carbon dioxide back to the atmosphere. These processes are often written in the short hand form called the carbonate silicate cycle: (13)CO2+CaSiO3⇔CaCO3+SiO2. Reaction (13) going to the right expresses ...

Viswanathan, in Carbon Dioxide to Chemicals and Fuels, 2018 Abstract Carbon dioxide (CO2) has to be considered as a useful raw (resource) material rather than waste material for the generation of fuels and chemicals. This chapter presents fundamentals on the carbon cycle, and an in-depth ...
The physics of solid carbon dioxide and its different polymorphs are not only of great practical and fundamental interest but also of considerable importance to terrestrial and planetary chemistry. Despite decades of computer simulations, the atomic-level structures of solid carbon dioxide polymorphs are...
