WebWe propose two novel kinds of liquid crystal (LC) filled D-shape photonic crystal fibers (PCFs) to realize the simultaneous measurement of refractive index (RI) and temperature. The gold film is selected as the plasmonic metal and coated on the D-shaped air hole of the PCF to excite the surface plasmon resonance (SPR). According to the position where the … WebEnter the fascinating world of liquid crystals. Liquid crystals were accidentally discovered in 1888 by Austrian botanist Friedrich Reinitzer while he studied cholesteryl benzoate of carrots. Reinitzer observed that …

WebJul 16, 2024 · In this paper, inspired by chameleons, we proposed a multifunctional E-skin by using a composite conductive cellulose liquid-crystal hydrogel, as shown in Fig. 1.Contrasting to human skin, chameleon’s skin possesses additional capability to change its color by control inside periodic guanine nanocrystal arrays ().In order to mimic this … Liquid crystals can be divided into 3 main types: thermotropic, lyotropic, and metallotropic. Thermotropic and lyotropic liquid crystals consist mostly of organic molecules, although a few minerals are also known. Thermotropic LCs exhibit a phase transition into the LC phase as temperature changes. See more Liquid crystal (LC) is a state of matter whose properties are between those of conventional liquids and those of solid crystals. For example, a liquid crystal may flow like a liquid, but its molecules may be oriented in a crystal … See more A large number of chemical compounds are known to exhibit one or several liquid crystalline phases. Despite significant differences in chemical composition, these molecules have … See more Lyotropic liquid-crystalline phases are abundant in living systems, the study of which is referred to as lipid polymorphism. Accordingly, lyotropic liquid crystals attract particular attention … See more Anisotropy of liquid crystals is a property not observed in other fluids. This anisotropy makes flows of liquid crystals behave more differentially than those of ordinary fluids. For example, injection of a flux of a liquid crystal between two close parallel plates ( See more In 1888, Austrian botanical physiologist Friedrich Reinitzer, working at the Karl-Ferdinands-Universität, examined the physico-chemical properties of various derivatives of cholesterol which now belong to the class of materials known as cholesteric liquid … See more The various liquid-crystal phases (called mesophases) can be characterized by the type of ordering. One can distinguish positional order (whether molecules are arranged in any … See more Examples of liquid crystals can also be found in the mineral world, most of them being lyotropic. The first discovered was vanadium(V) oxide, … See more WebLiquid crystals (LCs), an intermediate phase between a liquid and a crystalline solid, were first observed in 1888 by Reinitzer. These substances, which typically consist of two … granny chapter 2 official website
