intercalation
/ɪnˌtɜːrkəˈleɪʃən/
Definition
The reversible process of inserting ions or atoms into the structural lattice of a solid material, commonly used in battery-like electrode systems.
Etymology
Derived from the Latin 'intercalare', meaning to insert or proclaim a day to be inserted into the calendar. It entered scientific English to describe the act of inserting objects or layers between others.
In the news
The authors utilize proton-intercalation electrodes to control the alkalinity of a solution, which enables the efficient capture of carbon dioxide from the air. This mechanism is essential for the device's ability to cycle between absorbing and releasing CO2.
