Ludwig Maria Pohl (28 September 1932 – 24 October 2020) was an organic chemist, who was instrumental in developing new liquid crystal substance classes and compounds which made liquid crystal displays (LCDs) widely used. His team at Merck KGaA, Darmstadt, developed liquid crystal mixtures optimized for various applications. Over years, the ...
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.
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.
The Crystallography Open Database (COD) is a database of crystal structures. [1] 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databases, the database is entirely open-access, with registered users able to contribute published and unpublished structures of small molecules and small to medium-sized unit cell crystals to the database.
The AMLCI is a center of study for liquid crystal technology and education, blending basic and applied research on liquid crystals. This approach has resulted in technological advances and new applications such as display tablets, optical shutters, variable transmission windows, projection display devices, and flexible displays. Established in ...

In 2011, the Magnetic Space Groups data compiled from H.T. Stokes & B.J. Campbell's [4] and D. Litvin's [5] 's works general positions/symmetry operations and Wyckoff positions for different settings, along with systematic absence rules have also been incorporated into the server and a new shell has been dedicated to the related tools (MGENPOS, MWYCKPOS, MAGNEXT).
