Crystallography Open Database
The Crystallography Open Database (COD) is a database of crystal structures. Unlike similar crystallographic databases, the database is entirely open-access, with registered users able to contribute published and unpublished structures of small molecules and small to medium-sized unit cell crystals to the database. As of November 2024, the database has more than 520,000 entries. The database has various contributors, and contains Crystallographic Information Files as defined by the International Union of Crystallography (IUCr). There are currently five sites worldwide that mirror this database. The 3D structures of compounds can be converted to input files for 3D printers. See also * Crystallography Crystallography is the branch of science devoted to the study of molecular and crystalline structure and properties. The word ''crystallography'' is derived from the Ancient Greek word (; "clear ice, rock-crystal"), and (; "to write"). In J ... * Crystallographic database R ...

Database
In computing, a database is an organized collection of data or a type of data store based on the use of a database management system (DBMS), the software that interacts with end users, applications, and the database itself to capture and analyze the data. The DBMS additionally encompasses the core facilities provided to administer the database. The sum total of the database, the DBMS and the associated applications can be referred to as a database system. Often the term "database" is also used loosely to refer to any of the DBMS, the database system or an application associated with the database. Before digital storage and retrieval of data have become widespread, index cards were used for data storage in a wide range of applications and environments: in the home to record and store recipes, shopping lists, contact information and other organizational data; in business to record presentation notes, project research and notes, and contact information; in schools as flash c ...

Crystallography
Crystallography is the branch of science devoted to the study of molecular and crystalline structure and properties. The word ''crystallography'' is derived from the Ancient Greek word (; "clear ice, rock-crystal"), and (; "to write"). In July 2012, the United Nations recognised the importance of the science of crystallography by proclaiming 2014 the International Year of Crystallography.UN announcement "International Year of Crystallography" iycr2014.org. 12 July 2012 Crystallography is a broad topic, and many of its subareas, such as X-ray crystallography, are themselves important scientific topics. Crystallography ranges from the fundamentals of crystal structure to the mathematics of Crystal system, crystal geometry, including those that are Aperiodic crystal, not periodic or quasi ...

Vilnius University
Vilnius University ( Lithuanian: ''Vilniaus universitetas'') is a public research university, which is the first and largest university in Lithuania, as well as one of the oldest and most prominent higher education institutions in Central and Eastern Europe. Today, it is Lithuania's leading research institution. The university was founded in 1579 as the Jesuit Academy (College) of Vilnius by Stephen Báthory. It was the third oldest university (after the Cracow Academy and the Albertina) in the Polish–Lithuanian Commonwealth. Due to the failure of the November Uprising (1830–1831), the university was closed down and suspended its operation until 1919. In the aftermath of World War I, the university saw failed attempts to restart it by the local Poles, Lithuanians, and by invading Soviet forces. It finally resumed operations as Polish Stefan Batory University in August 1919. After the Soviet invasion of Poland in September 1939, the university was briefly administered by t ...

Crystallographic Information File
Crystallographic Information File (CIF) is a standard text file format for representing crystallographic information, promulgated by the International Union of Crystallography (IUCr). CIF was developed by the IUCr Working Party on Crystallographic Information in an effort sponsored by the IUCr Commission on Crystallographic Data and the IUCr Commission on Journals. The file format was initially published by Hall, Allen, and Brown and has since been revised, most recently versions 1.1 and 2.0. Full specifications for the format are available at the IUCr website. Many computer programs for molecular viewing are compatible with this format, including Jmol. mmCIF Closely related is mmCIF, macromolecular CIF, which is intended as an successor to the Protein Data Bank (PDB) format. It is now the default format used by the Protein Data Bank.— Also closely related is Crystallographic Information Framework, a broader system of exchange protocols based on data dictionaries and relation ...

Crystallographic Database
A crystallographic database is a database specifically designed to store information about the structure of molecules and crystals. Crystals are solids having, in all three dimensions of space, a regularly repeating arrangement of atoms, ions, or molecules. They are characterized by symmetry, morphology, and directionally dependent physical properties. A crystal structure describes the arrangement of atoms, ions, or molecules in a crystal. (Molecules need to crystallize into solids so that their regularly repeating arrangements can be taken advantage of in X-ray, neutron, and electron diffraction based crystallography). Crystal structures of crystalline material are typically determined from X-ray or neutron single-crystal diffraction data and stored in crystal structure databases. They are routinely identified by comparing reflection intensities and lattice spacings from X-ray powder diffraction data with entries in powder-diffraction fingerprinting databases. Crystal struct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Union Of Crystallography
The International Union of Crystallography (IUCr) is an organisation devoted to the international promotion and coordination of the science of crystallography. The IUCr is a member of the International Council for Science (ICSU). Objectives The objectives of the IUCr are to promote international cooperation in crystallography and to contribute to all aspects of crystallography, to promote international publication of crystallographic research, to facilitate standardization of methods, units, nomenclatures and symbols, and to form a focus for the relations of crystallography to other sciences. The IUCr fulfils these objectives by publishing in print and electronically primary scientific journals through the ''Acta Crystallographica'' journal series, as well as '' Journal of Applied Crystallography'', '' Journal of Synchrotron Radiation'', '' IUCrJ'', the series of reference volumes ''International Tables for Crystallography'', distributing the quarterly ''IUCr Newsletter'', mai ...
