Lyman G. Parratt
Lyman G. Parratt (May 17, 1908 - June 29, 1995) was an American physicist. He is known for various research using x-rays. Parratt was born in Salt Lake City. In 1954, Parratt used x-rays to explore the surface of copper-coated glass, thereby creating the field of X-ray reflectometry.L. G. Parratt''Phys.

Salt Lake City
Salt Lake City (often shortened to Salt Lake and abbreviated as SLC) is the capital and most populous city of Utah, United States. It is the seat of Salt Lake County, the most populous county in Utah. With a population of 200,133 in 2020, the city is the core of the Salt Lake City metropolitan area, which had a population of 1,257,936 at the 2020 census. Salt Lake City is further situated within a larger metropolis known as the Salt Lake City–Ogden–Provo Combined Statistical Area, a corridor of contiguous urban and suburban development stretched along a segment of the Wasatch Front, comprising a population of 2,746,164 (as of 2021 estimates), making it the 22nd largest in the nation. It is also the central core of the larger of only two major urban areas located within the Great Basin (the other being Reno, Nevada). Salt Lake City was founded July 24, 1847, by early pioneer settlers led by Brigham Young, who were seeking to escape persecution they had experienced whi ...

X-ray Reflectivity
X-ray reflectivity (sometimes known as X-ray specular reflectivity, X-ray reflectometry, or XRR) is a surface-sensitive analytical technique used in chemistry, physics, and materials science to characterize surfaces, thin films and multilayers.J. Als-Nielsen, D. McMorrow, ''Elements of Modern X-Ray Physics'', Wiley, New York, (2001). It is a form of reflectometry based on the use of X-rays and is related to the techniques of neutron reflectometry and ellipsometry. The basic principle of X-ray reflectivity is to reflect a beam of X-rays from a flat surface and to then measure the intensity of X-rays reflected in the specular direction (reflected angle equal to incident angle). If the interface is not perfectly sharp and smooth then the reflected intensity will deviate from that predicted by the law of Fresnel reflectivity. The deviations can then be analyzed to obtain the density profile of the interface normal to the surface. History The technique appears to have first been ap ...

Redmond, Oregon
Redmond is a city in Deschutes County, Oregon, United States. Incorporated on July 6, 1910, the city is on the eastern side of Oregon's Cascade Range, in the High Desert in Central Oregon. From Redmond there is access to recreational opportunities. Redmond is a full-service municipality and one of the fastest-growing industrial and residential communities in Oregon. Redmond had a population of 32,421 in 2019, and the population continues to grow at a rate of about 6.7 percent each year. The city encompasses and is on a plateau, at an elevation of . Redmond is north of Bend—the county seat of Deschutes County— from Portland, from Salem—the capital of Oregon—and from Eugene. History Redmond was named after Frank T. Redmond, who settled in the area in 1905. It was platted in 1906 by a company which would become part of Central Oregon Irrigation District building a canal. Electrification and the Oregon Trunk Railway reached Redmond in 1911. The rail link opened m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Günther Porod
Günther Porod (; 1919 in Faak am See near Villach – 1984 in Graz) was an Austrian physicist. He is best known for his work on the small-angle X-ray scattering method, done in collaboration with his teacher Otto Kratky, and in particular for Porod's law, which describes the asymptote of the scattering intensity ''I(q)'' for large scattering wave numbers ''q''. In polymer physics, the worm-like chain model, introduced in a 1949 paper, is sometimes called the Kratky–Porod model. In 1965 Porod was appointed as professor of experimental physics at the university of Graz. In 1978, he was awarded the Erwin Schrödinger-Preis. See also *Lyman G. Parratt Lyman G.

People From Salt Lake City
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of p ...
