1. 1. Dielectric Relaxation in Dielectric Mixtures

   Författare :Enis Tuncer; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In this thesis dielectric properties of both ideal composite structures and polymeric composite materials were investigated. Numerical calculations were performed to simulate frequency response of interfacial polarization using the finite element method in two dimensions. LÄS MER

4. 3. Relaxation dynamics of perturbed water and other H-bonded liquids

   Författare :Johan Sjöström; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; confinement; supercooled water; dielectric relaxation; mixtures;

   Sammanfattning : Most liquids can be supercooled below its melting point where the dynamics dramatically slows down with decreasing temperature until the material appears solid on the experimental time scale and becomes stuck in an out-of-equilibrium configuration, a glass. Water, one of the most abundant substances on earth, is no exception. LÄS MER

7. 5. Structures and Properties of Ferroelectric Liquid Crystal Displays

   Författare :Marek Matuszczyk; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; smectic; displays; dielectric anisotropy and biaxiality; surface-stabilized structure; dielectric; paraelectric; liquid crystal alignment; electroclinic effect; grey scale; polarization; multiplexing; liquid crystal LC ; orthogonal and tilted phases; chirality; aligning layer; ferroelectric; polyimide; rubbing; light valves and modulators; SSFLC;

   Sammanfattning : Liquid crystals have unique physical properties as they combine the features of solids and liquids. In thermotropic liquid crystals the degree of order varies with temperature resulting in an appearance of intermediate phases. LÄS MER
