Web1 day ago · Bis[3-(trimethoxysilyl)propyl] amine (BTPA) membranes doped with different metals, including Fe, Ni, and Ag, were applied to evaluate the permeation properties of H 2, N 2, and NH 3.All metal-coordinated BTPA gels showed superior NH 3 adsorption and desorption capacity via NH 3 temperature-programmed desorption (NH 3-TPD), which … The process of permeation involves the diffusion of molecules, called the permeant, through a membrane or interface. Permeation works through diffusion; the permeant will move from high concentration to low concentration across the interface. A material can be semipermeable, with the presence of a … See more In physics and engineering, permeation (also called imbuing) is the penetration of a permeate (a fluid such as a liquid, gas, or vapor) through a solid. It is directly related to the concentration gradient of the permeate, a material's See more • Packaging: The permeability of the package (materials, seals, closures, etc.) needs to be matched with the sensitivity of the package contents and the specified shelf life. Some packages must have nearly hermetic seals while others can (and sometimes must) be … See more • Moisture vapor transmission rate – Measure of the passage of water vapor through a substance • Oxygen transmission rate – … See more • Permeant: The substance or species, ion, molecules permeating through the solid. • Semipermeability: Property of a material to be permeable only … See more Abbé Jean-Antoine Nollet (physicist, 1700–1770) Nollet tried to seal wine containers with a pig's bladder and … See more The permeation of films and membranes can be measured with any gas or liquid.
