Calcium-Based Functionalization of Carbon Materials for …
We report a first-principles study of a CO 2 gas-sorbent material consisting of calcium atoms and carbon-based nanostructures. In the low gas pressure regime, we find that Ca decoration of nanotubes and graphene possess unusually large CO 2 uptake capacities (∼0.4–0.6 g CO 2 /g sorbent) as a result of their topology and a strong interaction between the metal dopants and CO 2 molecules.

Got Calcium? - Cannabis Business Times
Calcium is considered a plant macronutrient. In their book “Plant Physiology 4th edition,” Frank Salisbury and Cleon Ross define a macronutrient as any element with a concentration above 1,000 mg/kg or 0.1 percent in the plant tissue. Secondly, calcium is not
Calcium Metal | AMERICAN ELEMENTS
Calcium Metal is available as disc, granules, ingot, pellets, pieces, powder, rod, wire, and sputtering target. Ultra high purity and high purity forms also include metal powder, submicron powder and nanoscale, quantum dots, targets for thin film deposition, pellets for evaporation and single crystal or polycrystalline forms.
Calcium carbonate - Essential Chemical Industry
Calcium carbonate (limestone) is heated to form calcium oxide (quicklime) and carbon dioxide: It is an endothermic reaction and the equilibrium lies far to the left at low temperatures. Only at about 1200 K does the partial pressure of carbon dioxide exceed atmospheric pressure and the decomposition proceeds to completion.
