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.
The method of chemical library generation usually depends on the project and there are many factors to consider when using rational methods to select screening compounds. [2] Typically, a range of chemicals is screened against a particular drug target or disease model, and the preliminary "hits", or chemicals that show the desired activity, are ...
It was adopted by the International Union of Crystallography , who also provides full specifications of the format. [2] It is supported by all major crystallographic databases. The increasing automation of the crystal structure determination process has resulted in ever higher publishing rates of new crystal structures and, consequentially, new ...
[1] [7] Lehmann was the first to coin the term liquid crystal. [8] Studies in liquid crystals soon blossomed, and in 1922 Georges Friedel created the classification system of liquid crystals still used today. In this system, he named the chiral variety of liquid crystals cholesteric, as they were discovered from a cholesterol derivative. [5] [9]
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databases, the database is entirely open-access, with registered users able to contribute published and unpublished structures of small molecules and small to medium-sized unit cell crystals to the database.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 rendering engine starts and a dialog appears to show the rendering progress. When rendering is complete, the dialog shows "The document file has been generated.

Polymeric liquid crystals are similar to monomeric liquid crystals used in displays. [1] Both have dielectric anitroscopy, or the ability to change directions and absorb or transmit light depending on electric fields.
Inorganic Crystal Structure Database (ICSD) is a chemical database founded in 1978 by Günter Bergerhoff at the University of Bonn in Germany and I. D. Brown at McMaster University in Canada.
