Porosity is a measure of the void spaces in a material and is a critical factor in determining the storage and movement of fluids in geological formations. It significantly influences the physical properties and behavior of materials, impacting fields like hydrogeology, petroleum engineering, and soil science.
Permeability is a measure of how easily a fluid can flow through a porous material, and it is a critical property in fields like geology, civil engineering, and materials science. It is influenced by factors such as the size and connectivity of the pores, the viscosity of the fluid, and the pressure gradient driving the flow.
Pore structure refers to the arrangement and characteristics of pores within a material, which significantly influences its physical properties such as permeability, strength, and reactivity. Understanding Pore structure is crucial in fields like material science and geology, where it impacts processes like fluid flow, filtration, and adsorption.
Size-exclusion chromatography is a separation technique that sorts molecules based on their size by passing them through a porous matrix. Larger molecules elute first because they are excluded from entering the pores, while smaller molecules penetrate the pores and elute later.
