Unreferenced date October 2007 Image HEXAGONALPHASE1.JPG thumb right Schematic of the molecular organisation in a type I hexagonal lyotropic liquid crystalline phase. A hexagonal phase of lyotropic liquid crystal is formed by some amphiphilic molecules when they are mixed with water or another polar solvent. In this phase, the amphiphile molecules are aggregated into cylindrical structures of indefinite length and these cylindrical aggregates are disposed on a hexagonal lattice, giving the phase long range orientational order. In normal topology hexagonal phases, which are formed by type I amphiphiles , the hydrocarbon chains are contained within the cylindrical aggregates such that the polar apolar interface has a positive mean curvature . Inverse topology hexagonal phases have water within the cylindrical aggregates and the hydrocarbon chains fill the voids between the hexagonally packed cylinders. Normal topology hexagonal phases are denoted by H sub I sub while inverse topology hexagonal phases are deonted by H sub II sub . When viewed under a polarising microscope , thin films of both normal and inverse topology hexagonal phases exhibit birefringence , giving rise to characteristic optical textures. Typically, these textures are smoke like, fan like or mosaic in appearance. The phases are highly viscous and small air bubbles trapped within the preparation have highly distorted shapes. gallery Image Hexagonal1a.jpg smokey optical texture of type I hexagonal phase Image Hexagonal2a.jpg mosaic optical texture of type I hexagonal phase Image Hexagonal3a.jpg mosaic focal conic optical texture of type I hexagonal phase gallery Category Liquid crystals ... more details

Prism polyhedra db Prism polyhedron stat table P5 In geometry , the pentagonal prism is a Prism geometry prism with a pentagon al base. It is a type of heptahedron with 7 Face geometry faces , 15 Edge geometry edges , and 10 vertex geometry vertices . As a semiregular or uniform polyhedron If faces are all regular, the pentagonal prism is a semiregular polyhedron , more generally, a uniform polyhedron , and the third in an infinite set of prisms formed by square sides and two regular polygon caps. It can be seen as a truncation geometry truncated hosohedron pentagonal hosohedron , represented by Schl fli symbol t 2,5 . Alternately it can be seen as the Cartesian product of a regular pentagon and a line segment , and represented by the product 5 x . The dual polyhedron dual of a pentagonal prism is a pentagonal bipyramid . The symmetry group of a right pentagonal prism is dihedral group D sub 5h sub of order 20. The Point groups in three dimensions Rotation groups rotation group is D sub 5 sub of order 10. Volume The volume, as for all prisms, is the product of the area of the pentagonal base times the height or distance along any edge perpendicular to the base. For a uniform pentagonal prism with edges h the formula is math frac h 3 4 sqrt 5 5 2 sqrt 5 math See also Prism geometry Set of prisms Triangular prism Cube Square capped prismHexagonalprism Use Nonuniform pentagonal prisms called Pentaprism s are also used in optics to rotate an image through a right angle without changing its chirality .

Some texts may apply the term rectangular prism or square prism to both a right rectangular sided prism and a right square sided prism. The term uniform prism can be used for a right prism with square sides, since such prisms are in the set of uniform polyhedra .
