1. the presence of extremely small pores or void spaces in a material, typically measured at the microscopic level
Usage: technical; materials science

Examples

• The microporosity of the ceramic filter allows it to remove bacteria from water.
• Scientists studied the microporosity of the rock samples to understand fluid flow.
• The catalyst’s effectiveness depends on its microporosity and surface area.
• Advanced imaging techniques revealed the microporosity of the concrete.
• The membrane’s microporosity determines its selectivity for different molecules.
• Researchers measured the microporosity using nitrogen adsorption methods.
