Fluor-buergerite, originally named buergerite, is a mineral species belonging to the tourmaline group. It was first described for an occurrence in rhyolitic cavities near Mexquitic, San Luis Potosi, Mexico. It was approved as a mineral in 1966 by the IMA and named in honor of Martin J. Buerger (1903–1986), professor of mineralogy at the Massachusetts Institute of Technology.

Institute Professor
An institute is an organisational body created for a certain purpose. They are often research organisations (research institutes) created to do research on specific topics, or can also be a professional body. In some countries, institutes can be part of a university or other institutions of higher education, either as a group of departments or an autonomous educational institution without a traditional university status such as a "university institute" (see Institute of Technology). In some countries, such as South Korea and India, private schools are sometimes referred to as institutes, and in Spain, secondary schools are referred to as institutes. Historically, in some countries institutes were educational units imparting vocational training and often incorporating libraries, also known as mechanics' institutes. The word "institute" comes from a Latin word ''institutum'' meaning "facility" or "habit"; from ''instituere'' meaning "build", "create", "raise" or "educate". U ...

American Crystallographic Association
The American Crystallographic Association, Inc. (ACA) is a non-profit, scientific organization for scientists who study the structure of matter via crystallographic methodologies. Since its founding in 1949 it has amassed over 2000 members worldwide. The association meets annually in July and has several interest groups dealing with specific aspects of crystallography, including fiber diffraction, neutron scattering and powder diffraction. A quarterly magazine, called ''ACA RefleXions'', is published in addition to a scholarly journal. ''Structural Dynamics'' is a peer-reviewed, open access, online-only journal co-published by ACA and AIP Publishing. It highlights research articles on structural determination and dynamics of systems, enabled by the emerging new instruments (e.g. XFELs, high harmonic generation, ultra-short electron sources, etc.) and new experimental and theoretical methodologies. The journal is accepting short communications, topical reviews, and research paper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mineral
In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form.John P. Rafferty, ed. (2011): Minerals'; p. 1. In the series ''Geology: Landforms, Minerals, and Rocks''. Rosen Publishing Group. The geological definition of mineral normally excludes compounds that occur only in living organisms. However, some minerals are often biogenic (such as calcite) or are organic compounds in the sense of chemistry (such as mellite). Moreover, living organisms often synthesize inorganic minerals (such as hydroxylapatite) that also occur in rocks. The concept of mineral is distinct from rock, which is any bulk solid geologic material that is relatively homogeneous at a large enough scale. A rock may consist of one type of mineral, or may be an aggregate of two or more different types of minerals, spacially segregated into distinct ...

Lincoln, Massachusetts
Lincoln is a town in Middlesex County, Massachusetts, Middlesex County, Massachusetts. The population was 7,014 according to the 2020 United States Census, including residents of Hanscom Air Force Base that live within town limits. The town, located in the MetroWest region of Boston's suburbs, has a rich colonial history and large amounts of public conservation land. History Lincoln was settled by Europeans in 1654, as a part of Concord, Massachusetts, Concord. The majority of Lincoln was formed by splitting off a substantial piece of southeast Concord and incorporated as a separate town in 1754. Due to their "difficulties and inconveniences by reason of their distance from the places of Public Worship in their respective Towns," local inhabitants petitioned the General Court to be set apart as a separate town. Because the new town was composed of parts "nipped" off from the adjacent towns of Concord, Massachusetts, Concord, Weston, Massachusetts, Weston (which itself had been ...
