porozymetry

Porozymetry is a scientific field dedicated to the study and measurement of pore structures within materials. It encompasses a variety of techniques used to characterize the size, shape, distribution, and connectivity of pores. Understanding these characteristics is crucial for a wide range of applications, as pore structure significantly influences material properties such as permeability, surface area, mechanical strength, and adsorption behavior.

The fundamental goal of porozymetry is to gain insight into the internal architecture of porous media. This can range from macroscopic pores found in rocks and ceramics to microscopic pores in activated carbon, zeolites, and biological tissues. Different methods are employed depending on the pore size range and the material being investigated. Common techniques include mercury intrusion porosimetry, gas adsorption (e.g., nitrogen adsorption), small-angle X-ray scattering (SAXS), and nuclear magnetic resonance (NMR) porosimetry. Each technique offers complementary information about the pore network.

Applications of porozymetry are diverse. In geology, it helps understand oil and gas reservoir potential and groundwater flow. In materials science, it is vital for developing catalysts, filters, membranes, and advanced composites. In biology and medicine, it aids in studying bone porosity, drug delivery systems, and tissue engineering. By quantifying pore characteristics, porozymetry enables the rational design and optimization of materials for specific performance requirements.
