What is interstitial?

Interstitial refers to a space or gap between things, often used in a technical or scientific context. Here's a breakdown:

  • Definition: The term "interstitial" generally means "situated within or between." It describes something that occupies the gaps or spaces between other structures or components.

  • Chemistry: In Chemistry, an interstitial compound is a compound formed when small atoms (like hydrogen, boron, carbon, or nitrogen) occupy the spaces within the crystal lattice of a metal.

  • Medicine/Biology: In Medicine/Biology, "interstitial" refers to the space between cells in a tissue or organ. This space contains interstitial fluid, which plays a crucial role in nutrient and waste exchange. Interstitial lung disease, for example, affects the tissue surrounding the air sacs of the lungs.

  • Materials Science: In Materials%20Science, interstitial defects are point defects where an atom of the same type as those in the lattice occupies an interstitial site (a space between regular lattice sites).
