Langmuir (crater)
Langmuir is an impact crater on the Moon's Far side (Moon), 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 (crater), Chebyshev to the west-northwest and Brouwer (crater), Brouwer to the east. It partly overlaps the rims of these two craters, making it the youngest of the three. The outer wikt:rampart, 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 wiktionary:terrace, terrace structures and dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. 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, Web of Science The Web of Science (WoS; previously known as Web of Knowledge) is a paid-access platform that provides (typically via the internet) access to multiple databases that provide reference and citation data from academic journals, conference proceedi ..., and SwetsWise.

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 use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arrowsmith Peninsula
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, directo ...

Langmuir Monolayer
A monolayer is a single, closely packed layer of entities, commonly atoms or molecules. Monolayers can also be made out of cells. ''Self-assembled monolayers'' form spontaneously on surfaces. Monolayers of layered crystals like graphene and molybdenum disulfide are generally called '' 2D materials''. Types 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 transfer ...

Alexander Langmuir
Alexander Duncan Langmuir (; September 12, 1910 – November 22, 1993) was an American epidemiology, epidemiologist who served as Chief Epidemiologist of the Centers for Disease Control and Prevention (CDC) from 1949 to 1970, developing the Epidemic Intelligence Service (EIS) as a training program for epidemiologists. During his tenure, Langmuir broadened the CDC's scope to include the epidemiology of non-communicable diseases, environmental health, and family planning. Additionally, Langmuir increased coordination between the CDC and state and territorial epidemiologists. Langmuir has been praised for transferring publication of the ''Morbidity and Mortality Weekly Report'' (''MMWR'') to the CDC, ushering in plain English explanations of ongoing health crises that were useful for both scientists and members of the public. Early life and education Langmuir was born on September 12, 1910, in Santa Monica, California, to New York Life Insurance Company President Charles H. Lang ...

Gavin I
Gavin is a Celtic male given name. It is the Scottish variation of the medieval Welsh name Gawain, meaning 'God send' or 'white hawk/falcon'. Sir Gawain is a knight of King Arthur's Round Table. ''Sir Gawain and the Green Knight'' is an epic poem in which he 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 (and originally Sardinian) 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, later recovered and interred with his body. People with the given names 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 radio personality and ...
