Calcium — Wikipédia

Le calcium est un sel minéral. Il est le plus abondant de notre organisme, puisqu’il représente 2 % de notre poids corporel. Pour être plus précis, le calcium est un métal alcalino-terreux gris-blanc, particulièrement dur. Dans la nature, il est impossible de le trouver à l’état de corps pur.

Insights into the trapping mechanism of light metals on …

Our work presents insights from density functional theory calculations on the trapping mechanism of light metal atoms in CN-h2D. The storage capacity of CN-h2D for lithium, sodium and calcium ions has been explored for utilisation as a battery anode material. Our calculations show that a significant capacity of over 500 mAh g and excellent mobility of the calcium atoms can be achieved. Overall
