Langmuir (crater)
Langmuir is an impact crater on the Moon's far side. It is located in a region to the southwest of the Mare Orientale impact basin. Langmuir is bracketed between two larger craters, with Chebyshev to the west-northwest and Brouwer to the east. It partly overlaps the rims of these two craters, making it the youngest of the three. The outer rampart of ejecta from Langmuir partly covers the southeast interior floor of Chebyshev. This crater has not been heavily eroded, and many of its original features remain intact and sharply defined. The rim to the west is somewhat disrupted due to having overlaid the rim of the larger Chebyshev. In a coincidental arrangement, a small crater is situated across the rim edge at the northern end of where it joins with Chebyshev, and a smaller crater lies at the southern end of this merger. The inner wall of Langmuir contains some minor terrace Terrace may refer to: Landforms and construction * Fluvial terrace, a natural, flat surface that border ...

Langmuir (journal)
''Langmuir'' is a peer-reviewed scientific journal that was established in 1985 and is published by the American Chemical Society. It is the leading journal focusing on the science and application of systems and materials in which the interface dominates structure and function. Research areas covered include surface and colloid chemistry. The total number of citations in 2021 is 129,693 and the 2021 Impact Factor is 4.331. Langmuir publishes original research articles, invited feature articles, perspectives, and editorials. The title honors Irving Langmuir, winner of the 1932 Nobel Prize for Chemistry. The founding editor-in-chief was Arthur W. Adamson. Abstracting and indexing ''Langmuir'' is indexed in Chemical Abstracts Service, Scopus, EBSCOhost, British Library, PubMed PubMed is a free search engine accessing primarily the MEDLINE database of references and abstracts on life sciences and biomedical topics. The United States National Library of Medicine (NLM) at the N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Langmuir (unit)
The langmuir (symbol: L) is a unit of exposure (or dosage) to a surface (''e.g.'' of a crystal) and is used in ultra-high vacuum (UHV) surface physics to study the adsorption of gases. It is a practical unit, and is not dimensionally homogeneous, and so is used only in this field. It is named after American physicist Irving Langmuir. Definition The langmuir is defined by multiplying the pressure of the gas by the time of exposure. One langmuir corresponds to an exposure of 10−6 Torr during one second. For example, exposing a surface to a gas pressure of 10−8 Torr for 100 seconds corresponds to 1 L. Similarly, keeping the pressure of oxygen gas at 2.5·10-6 Torr for 40 seconds will give a dose of 100 L. Conversion Since both different pressures and exposure times can give the same langmuir (see Definition) it can be difficult to convert Langmuir (L) to exposure pressure × time (Torr·s) and vice versa. The following equation can be used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Langmuir Cove
Arrowsmith Peninsula () is a cape about long on the west coast of Graham Land, west of Forel Glacier, Sharp Glacier and Lallemand Fjord, and northwest of Bourgeois Fjord, with Hanusse Bay lying to the northwest. It was surveyed by the Falkland Islands Dependencies Survey (FIDS) in 1955-58 and named for Edwin Porter Arrowsmith, Governor of the Falkland Islands. Named features Various features along the coast of Arrowsmith Peninsula have been charted and named. The peninsula and many of its features were first seen and roughly surveyed in 1909 by the French Antarctic Expedition (FAE) under Jean-Baptiste Charcot. Unless otherwise noted, all of the following features were named by the United Kingdom Antarctic Place-Names Committee (UK-APC). Northern portion Shmidt Point marks the north extremity of Arrowsmith Peninsula. It was sketched from the air in 1937 by the British Graham Land Expedition (BGLE) under John Riddoch Rymill and named in 1954 for Otto Schmidt, director of th ...

Langmuir Monolayer
A monolayer is a single, closely packed layer of atoms, molecules, or cells. In some cases it is referred to as a self-assembled monolayer. Monolayers of layered crystals like graphene and molybdenum disulfide are generally called 2D materials. Chemistry A Langmuir monolayer or insoluble monolayer is a one-molecule thick layer of an insoluble organic material spread onto an aqueous subphase in a Langmuir-Blodgett trough. Traditional compounds used to prepare Langmuir monolayers are amphiphilic materials that possess a hydrophilic headgroup and a hydrophobic tail. Since the 1980s a large number of other materials have been employed to produce Langmuir monolayers, some of which are semi-amphiphilic, including polymeric, ceramic or metallic nanoparticles and macromolecules such as polymers. Langmuir monolayers are extensively studied for the fabrication of Langmuir-Blodgett film (LB films), which are formed by transferred monolayers on a solid substrate. A Gibbs monolayer or s ...

Alexander Langmuir
Alexander Duncan Langmuir (12 September 1910 – 22 November 1993) was an American epidemiologist. He is renowned for creating the Epidemic Intelligence Service. Biography Alexander D. Langmuir was born in Santa Monica, California. He received his A.B. in 1931 from Harvard, his M.D. in 1935 from Cornell University Medical College, and his M.P.H. in 1940 from the Johns Hopkins School of Hygiene and Public Health. After serving as a public health officer in New York and as an epidemiologist with the U. S. Army from 1942 to 1946, Langmuir returned to Johns Hopkins to become associate professor of epidemiology in the school of medicine. In 1949, he became director of the epidemiology branch of the National Communicable Disease Center (now the Centers for Disease Control and Prevention The Centers for Disease Control and Prevention (CDC) is the national public health agency of the United States. It is a United States federal agency, under the Department of Health and Human Ser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gavin I
Gavin is a male given name originating from Scotland. It is a variation on the medieval name Gawain, meaning "God send" or "white hawk" (or falcon). Sir Gawain was a knight of King Arthur's Round Table. ''Sir Gawain and the Green Knight'' is an epic poem connected with King Arthur's Round Table. Gawain beheads the Green Knight who promptly replaces his head and threatens Gawain an identical fate the same time next year. Decapitation figures elsewhere: the Italian name Gavino is the name of an early Christian martyr (San Gavino, Porto Torres, Sardinia) who was beheaded in 300 AD, his head being thrown in the Mediterranean Sea only later reunited and interred with his body. People with the given name People with the surname * Agnes Gavin (1872–1947), Australian actor and screenwriter * Andy Gavin (born 1970), American programmer * Barrie Gavin (born 1935), British film director * Barry Gavin (1944–2017), Australian rules footballer * Bill Gavin (1907–1985), American rad ...
