thermotropic การใช้

• Liquid crystals can be divided into thermotropic, lyotropic and metallotropic phases.
• This overriding behavior suggests integration between the plants'gravitropic and thermotropic systems.
• Thermotropic LCs exhibit a phase transition into the liquid-crystal phase as temperature is changed.
• Thermotropic and lyotropic liquid crystals consist mostly of organic molecules, although a few minerals are also known.
• These liquid crystalline phases are closer in architecture to thermotropic liquid crystalline phases than to the conventional lyotropic phases.
• The mesophase pitch forms a thermotropic crystal, which allows the pitch to become organized and form linear chains without the use of tension.
• Since lyotropic liquid crystals rely on a subtle balance of intermolecular interactions, it is more difficult to analyze their structures and properties than those of thermotropic liquid crystals.
• Thermotropic chiral LCs whose pitch varies strongly with temperature can be used as crude liquid crystal thermometers, since the color of the material will change as the pitch is changed.
• Feasible ways would be a reduction in optical gain ( for example, using thermotropic layers, or electrochromic devices ) or an increase in system losses, by dumping of the hot water excess.
• There is therefore a range of temperatures at which we observe thermotropic LCs; and most of these have several " subphases " ( nematic, smectic . . . ), which we may observe by modifying the temperature.
• The poly ( dialkylstannane ) s were found to be thermotropic and displayed first-order phase transitions from one liquid-crystalline phase into another or directly to the isotropic state, depending on the length of the side groups.
• Traditionally known PDLC consists of oil-in-water emulsion where the oily droplet is a thermotropic liquid crystal such as 4-pentyl-4'- cyanobiphenyl ( 5CB ), and the water phase contains certain polymers.
• These anisotropic self-assembled nano-structures can then order themselves in much the same way as thermotropic liquid crystals do, forming large-scale versions of all the thermotropic phases ( such as a nematic phase of rod-shaped micelles ).

• Stick-on aquarium thermometers ( the thin black plastic rectangle kind that goes on the outside of the tank ) are made with several liquid crystal strips; each strip exhibits a colour change at a different temperature . ( See thermotropic crystal and liquid crystal thermometer .)
• The aim of the Society is to unite scientists, engineers and students working in the broad field of fundamental and applied aspects of different liquid crystal systems, including thermotropic, lyotropic, polymer and polymer-modified liquid crystals . appearing under the sponsorship of Taylor & Francis, and archive-style electronic liquid crystal communications platform, e-lc.
• Hello . i was wondering if there is a way ( in theory even ) to calibrate thermotropic crystals to a color other than green ( at 82 F ) : let's say brown ? and then in that, is it possible to have a more focused color spectrum like dark brown-brown-milk brown ? or if thermotropic crystals are totally out of the question, what other substances / chemicals reflect specific color wavelenghts based on heat?
