Acta Crystallographica was established in conjunction with the foundation of the International Union of Crystallography in 1948. Both were established to maintain an international forum for crystallography after the Second World War had led to a loss of international subscription to, and the eventual nine-year closure of, the main pre-war crystallography journal, Zeitschrift für ...
Liquid crystal color transitions are used on many aquarium and pool thermometers as well as on thermometers for infants or baths. [84] Other liquid crystal materials change color when stretched or stressed. Thus, liquid crystal sheets are often used in industry to look for hot spots, map heat flow, measure stress distribution patterns, and so on.
CrystEngComm is a peer-reviewed online-only scientific journal publishing original research and review articles on all aspects of crystal engineering including properties, polymorphism, target materials, and crystalline nanomaterials. It is published biweekly by the Royal Society of Chemistry and the editor-in-chief is Pierangelo Metrangolo.
The hallmark of molecular excitons in organic molecular crystals are doublets and/or triplets of exciton absorption bands strongly polarized along crystallographic axes. In these crystals an elementary cell includes several molecules sitting in symmetrically identical positions, which results in the level degeneracy that is lifted by ...
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.
Liquid crystal – a state of matter with properties of both conventional liquids and crystals Patterson function – a function used to solve the phase problem in X-ray crystallography Periodic table (crystal structure) – (for elements that are solid at standard temperature and pressure) gives the crystalline structure of the most ...
The Journal of Crystal Growth was founded following the 1966 International Conference on Crystal Growth (ICCG) held in Boston, Massachusetts, United States.Ichiro Sunagawa, who participated in ICCG, wrote in the Journal of the Japanese Association of Crystal Growth that before then, "The crystal growth community was totally fragmented and had remained as a peripheral field at the mercy of ...
Same as the small molecular liquid crystal, liquid crystal polymers also have different mesophases. The mesogen cores of the polymers will aggregate into different mesophases: nematics, cholesterics, smectics and compounds with highly polar end groups. [10] More information about the mesophases can be found on liquid crystal page.
