Electron Microscope Society Of America
The Microscopy Society of America (MSA), founded in 1942 as The Electron Microscope Society of America, is a non-profit organization that provides microanalytical facilities for studies within the sciences. Currently, there are approximately 3000 members. The society holds an annual meeting, which is usually held in the beginning of August. It has 30 local affiliates across the United States. The society has a program for examining and certifying technologists of electron microscopes. The organization produces two journals: Microscopy Today, and Microscopy and Microanalysis. As of 2024, the President is Jay Potts. History A meeting of electron microscopists took place in November 1942 at the Sherman House Hotel in Chicago. It was organized by G. L. Clark of the University of Chicago. At this meeting the society was founded as the Electron Microscope Society of America (EMSA). For the 1949 meeting, the EMSA invited representatives from European microscopy societies, which may have b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electron Energy Loss Spectroscopy
Electron energy loss spectroscopy (EELS) is a form of electron microscopy in which a material is exposed to a beam of electrons with a known, narrow range of kinetic energies. Some of the electrons will undergo inelastic scattering, which means that they lose energy and have their paths slightly and randomly deflected. The amount of energy loss can be measured via an electron spectrometer and interpreted in terms of what caused the energy loss. Inelastic interactions include phonon excitations, inter- and intra- band transitions, plasmon excitations, inner shell ionizations, and Cherenkov radiation. The inner-shell ionizations are particularly useful for detecting the elemental components of a material. For example, one might find that a larger-than-expected number of electrons comes through the material with 285 eV less energy than they had when they entered the material. This is approximately the amount of energy needed to remove an inner-shell electron from a c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

David W
David (; , "beloved one") was a king of ancient Israel and Judah and the third king of the United Monarchy, according to the Hebrew Bible and Old Testament. The Tel Dan stele, an Aramaic-inscribed stone erected by a king of Aram-Damascus in the late 9th/early 8th centuries BCE to commemorate a victory over two enemy kings, contains the phrase (), which is translated as " House of David" by most scholars. The Mesha Stele, erected by King Mesha of Moab in the 9th century BCE, may also refer to the "House of David", although this is disputed. According to Jewish works such as the '' Seder Olam Rabbah'', '' Seder Olam Zutta'', and '' Sefer ha-Qabbalah'' (all written over a thousand years later), David ascended the throne as the king of Judah in 885 BCE. Apart from this, all that is known of David comes from biblical literature, the historicity of which has been extensively challenged,Writing and Rewriting the Story of Solomon in Ancient Israel; by Isaac Kalimi; pag ...

Deborah F
According to the Book of Judges, Deborah (, ''Dəḇōrā'') was a prophetess of Judaism, the fourth Judge of pre-monarchic Israel, and the only female judge mentioned in the Hebrew Bible. Many scholars contend that the phrase, "a woman of Lappidoth", as translated from biblical Hebrew in Judges 4:4 denotes her marital status as the wife of Lapidoth.Van Wijk-Bos, Johanna WH. ''The End of the Beginning: Joshua and Judges''. Wm. B. Eerdmans Publishing, 2019. Alternatively, "lappid" translates as "torch" or "lightning", therefore the phrase, "woman of Lappidoth" could be referencing Deborah as a "fiery woman." Deborah told Barak, an Israelite general from Kedesh in Naphtali, that God commanded him to lead an attack against the forces of Jabin king of Canaan and his military commander Sisera (Judges 4:6–7); the entire narrative is recounted in chapter 4. Judges 5 gives the same story in poetic form. This passage, often called ''The Song of Deborah'', may date to as early as the ...

James Hillier
James Hillier, (August 22, 1915 – January 15, 2007) was a Canadian- American scientist and inventor who designed and built, with Albert Prebus, the first successful high-resolution electron microscope in North America in 1938. Biography Born in Brantford, Ontario, the son of James and Ethel (Cooke) Hillier, he received a Bachelor of Arts in Mathematics and Physics (1937), Master of Arts (1938), and a Ph.D (1941) from the University of Toronto, where, as a graduate student, he completed a prototype of the electron microscope that had been invented by Ernst Ruska. This transmission electron microscope was used as a prototype for later electron microscopes. In 1941, he went to the United States of America and joined the Radio Corporation of America in Camden, New Jersey. He became General Manager, RCA Laboratories (1957); Vice President, RCA Laboratories (1958); Vice President, Research and Engineering (1968); Executive Vice President, Research and Engineering (1969); an ...

David Harker
David Harker (October 19, 1906 – February 27, 1991) was an American medical researcher who according to ''The New York Times'' was "a pioneer in the use of X-rays to decipher the structure of critical substances in the life process of cells". He is also well known for Harker–Kasper inequalities (statistical relationships between the phases of structure factors), which he devised in collaboration with John S. Kasper. Harker made seminal discoveries in the field of chemical crystallography. His lab solved the structure of the pancreatic enzyme ribonuclease A, the third protein structure ever solved by protein crystallography. Harker was a member of the National Academy of Sciences, director of the protein structure program at the Polytechnic Institute of Brooklyn, director of the Center for Crystallographic Research at Roswell Park Comprehensive Cancer Center, and the head of the crystallography division of General Electric.
