porieachtige

Porieachtige is a Dutch adjective meaning porous or having pores. In science and engineering it describes a material or structure that contains pore spaces between its solid constituents. Porieachtige materials exhibit porosity, the fraction of volume that is void, which can be open (connected) or closed (isolated). The pore network influences how fluids and gases move through the material and affects permeability, diffusivity, insulation, density, and mechanical strength.

Pore sizes range from micro- to macro-scale: micropores (<2 nm), mesopores (2–50 nm), and macropores (>50 nm). Porosity can be described as absolute, apparent, or effective porosity. Measurements include gravimetric porometry, mercury intrusion porosimetry, gas adsorption (BET), and imaging like CT scanning.

Porieachtige structures occur naturally in soils and rocks, such as sandstone, porous limestone, and wood, enabling drainage, groundwater flow, and nutrient transport. They also appear in engineered materials like ceramic foams, porous polymers, activated carbon, and catalyst supports, where porosity is tailored for filtration, insulation, or energy storage. In biology and medicine, porous scaffolds support tissue growth by allowing cell infiltration and nutrient diffusion.

In summary, porieachtige describes materials with a pore network whose size, connectivity and volume determine transport properties and functional performance. Etymology: from Dutch porie meaning pore and -achtig meaning like.
