Porous polymers are a class of porous media materials in which monomers form 2D and 3D polymers containing angstrom- to nanometer-scale pores formed by the ...
It was in 1926 when Beckam proposed the utilisation of microorganisms as agents for recovering the remnant oil entrapped in porous media. [1] [2] [3] [5] Since that time numerous investigations have been developed, and are extensively reviewed.
Reactive transport models are constructed to understand the composition of natural waters; the origin of economic mineral deposits; the formation and dissolution of rocks and minerals in geologic formations in response to injection of industrial wastes, steam, or carbon dioxide; and the generation of acidic waters and leaching of metals from mine wastes.
At the microscopic and macroscopic levels, porous media can be classified. At the microscopic scale, the structure is represented statistically by the distribution of pore sizes, the degree of pore interconnection and orientation, the proportion of dead pores, etc. [4] The macroscopic technique makes use of bulk properties that have been averaged at scales far bigger than pore size.
A porous medium is composed of fluid and solid domains, which act together to describe the mechanical behavior of the material. Natural substances including rocks, [2] soils, [3] biological tissues including heart [4] and cancellous bone, [5] and man-made materials such as foams, ceramics, and concrete [6] can be considered as porous media ...
Micro CT of porous medium: Pores of the porous medium shown as purple color and impermeable porous matrix shown as green-yellow color. Pore structure is a common term employed to characterize the porosity, pore size, pore size distribution, and pore morphology (such as pore shape, surface roughness, and tortuosity of pore channels) of a porous medium.
Living along the coast of Peru from around 900 to 1500 A.D., the Chancay people was well known for their impressive artwork, including wood carvings, ceramics, and textiles.
Symbol used to represent in situ permeability tests in geotechnical drawings. In fluid mechanics, materials science and Earth sciences, the permeability of porous media (often, a rock or soil) is is a measure of the ability for fluids (gas or liquid) to flow through the media; it is commonly symbolized as k.
