The Langmuir adsorption model deviates significantly in many cases, primarily because it fails to account for the surface roughness of the adsorbent. Rough inhomogeneous surfaces have multiple site types available for adsorption, with some parameters varying from site to site, such as the heat of adsorption.
Specifically, it was through the models of Overton, Langmuir, Gorter and Grendel, and Davson and Danielli, that it was deduced that membranes have lipids, proteins, and a bilayer. The advent of the electron microscope, the findings of J. David Robertson , the proposal of Singer and Nicolson , and additional work of Unwin and Henderson all ...

Perhaps one of the hottest most recent SI models is Chrissy Teigen. And after being a cover star for the first time in 2014, she returned to the magazine this year again and looks hotter than ever.
Jill De Vries (born July 20, 1953) is an American model. She was Playboy magazine's Playmate of the Month for the October 1975 issue. [15] Her centerfold was photographed by Dwight Hooker. [16] De Vries's was the first Playboy gatefold to be signed by the model. De Vries was studying to be a teacher at the time of her pictorial.
Langmuir (unit), a unit of exposure of an adsorbate/gas to a substrate used in surface science to study adsorption; Langmuir Cove, a cove in the north end of Arrowsmith Peninsula, Graham Land, Antarctica; Langmuir monolayer, a one-molecule thick layer of an insoluble organic material spread onto an aqueous subphase in a Langmuir-Blodgett trough
The idea of a Langmuir–Blodgett (LB) film was first proven feasible in 1917 when Irving Langmuir (Langmuir, 1917) showed that single water-surface monolayers could be transferred to solid substrates. 18 years later, Katharine Blodgett made an important scientific advance when she discovered that several of these single monolayer films could be stacked on top of one another to make multilayer ...
Irving Langmuir (/ ˈ l æ ŋ m j ʊər /; [2] January 31, 1881 – August 16, 1957) was an American chemist, physicist, and metallurgical engineer. He was awarded the Nobel Prize in Chemistry in 1932 for his work in surface chemistry .
