Renee Diehl
Renee D. Diehl is an American physicist known for her work on the adsorption and physisorption of atoms and molecules onto crystal and quasicrystal surfaces, including the first experimental studies showing that non-reactive atoms on metal surfaces did not necessarily rest in crevices on the surface. She is a professor emerita of physics at the Pennsylvania State University. Education and career Diehl was educated at the Shippensburg High School in Pennsylvania, and majored in physics at Juniata College, also in Pennsylvania. She graduated in 1976, and continued her studies at the University of Washington, where she completed a Ph.D. in 1982, supervised by Samuel C. Fain. After postdoctoral studies at the University of Liverpool in the UK, she continued as a lecturer in Liverpool from 1983 to 1990. She returned to Pennsylvania and joined the Pennsylvania State University faculty in 1990, becoming a full professor there in 1998. Recognition In 1999, the American Association of ...

Adsorption
Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface. This process creates a film of the ''adsorbate'' on the surface of the ''adsorbent''. This process differs from absorption, in which a fluid (the ''absorbate'') is dissolved by or permeates a liquid or solid (the ''absorbent''). While adsorption does often precede absorption, which involves the transfer of the absorbate into the volume of the absorbent material, alternatively, adsorption is distinctly a surface phenomenon, wherein the adsorbate does not penetrate through the material surface and into the bulk of the adsorbent. The term '' sorption'' encompasses both adsorption and absorption, and ''desorption'' is the reverse of sorption. Like surface tension, adsorption is a consequence of surface energy. In a bulk material, all the bonding requirements (be they ionic, covalent or metallic) of the constituent atoms of the material are fulfilled by other atoms in ...

Graduate Women In Science
Graduate Women in Science (GWIS), formerly known as Sigma Delta Epsilon (ΣΔΕ), is an international professional organization for women in science. It was established as a scientific women's fraternity in 1921 at Cornell University, United States. It played an important role for women scientists for some fifty years when they were not allowed membership in most mainstream scientific organizations. GWIS is a non-profit 501(c)(3) organization with over 1,000 active members and more than 30 active chapters. History Sigma Delta Epsilon was established at Cornell University in Ithaca, New York by Adele Lewis Grant on May 24, 1921. It was founded as a fraternity for women pursuing graduate degrees in the sciences.Robson, John, ed. (1963). ''Baird's Manual of American College Fraternities'' (17th ed.). Menasha, Wisconsin: The Collegiate Press, George Banta Company, Inc. pp. 693 Its stated purpose was "to further interest in science, recognize women involved in science, and unite them t ...

University Of Washington Alumni
A university () is an institution of tertiary education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase , which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law and notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hilde''A History of the University in Europe: Volume 1, Universities in the ...

Year Of Birth Missing (living People)
A year is a unit of time based on how long it takes the Earth to orbit the Sun. In scientific use, the tropical year (approximately 365 solar days, 5 hours, 48 minutes, 45 seconds) and the sidereal year (about 20 minutes longer) are more exact. The modern calendar year, as reckoned according to the Gregorian calendar, approximates the tropical year by using a system of leap years. The term 'year' is also used to indicate other periods of roughly similar duration, such as the lunar year (a roughly 354-day cycle of twelve of the Moon's phasessee lunar calendar), as well as periods loosely associated with the calendar or astronomical year, such as the seasonal year, the fiscal year, the academic year, etc. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by changes in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fulbright Fellow
The Fulbright Program, including the Fulbright–Hays Program, is one of several United States cultural exchange programs with the goal of improving intercultural relations, cultural diplomacy, and intercultural competence between the people of the United States and other countries through the mutual exchange of persons, knowledge, and skills. The program was founded by United States Senator J. William Fulbright in 1946, and has been considered as one of the most prestigious scholarships in the United States. Via the program, competitively selected American citizens including students, scholars, teachers, professionals, scientists, and artists may receive scholarships or grants to study, conduct research, teach, or exercise their talents abroad; and citizens of other countries may qualify to do the same in the United States. The program provides approximately 8,000 grants annually, comprising roughly 1,600 grants to U.S. students, 1,200 to U.S. scholars, 4,000 to foreign stud ...

Physisorption
Physisorption, also called physical adsorption, is a process in which the electronic structure of the atom or molecule is barely wikt:perturb, perturbed upon adsorption. Overview The fundamental interacting force of physisorption is Van der Waals force. Even though the interaction energy is very weak (~10–100 meV), physisorption plays an important role in nature. For instance, the Van der Waals force, van der Waals attraction between surfaces and foot-hairs of geckos (see Synthetic setae) provides the remarkable ability to climb up vertical walls. Van der Waals forces originate from the interactions between induced, permanent or transient electric dipoles. In comparison with chemisorption, in which the electronic structure of bonding atoms or molecules is changed and covalent or ionic bonds form, physisorption does not result in changes to the chemical bonding structure. In practice, the categorisation of a particular adsorption as physisorption or chemisorption depe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
