1. an extremely small pore or opening, typically measured in micrometers
Usage: scientific; technical

Examples

• The activated carbon filter contains millions of micropores that trap contaminants.
• Scientists studied the micropore structure of the rock sample.
• The membrane’s micropores allow only water molecules to pass through.
• Micropores in the soil help retain moisture and nutrients.
• The catalyst’s effectiveness depends on its micropore distribution.
• Researchers measured the micropore diameter using advanced imaging techniques.
