New Liquid Crystalline [2]Rotaxanes
… and characterization of a range of new liquid crystalline interlocked molecules and to study structure-property relationships between rotaxane design and mesomorphism. Chapter 1 introduces concepts of supramolecular chemistry and liquid crystals and cooperative effect between [2]rotaxane and …

Broadly tuneable crystalline Raman lasers
… demonstration of a continuous-wave third-Stokes crystalline Raman laser. This was achieved via intracavity Raman conversion of a vertical external cavity surface emitting laser (VECSEL), also known as a semiconductor disk laser (SDL). The VECSEL-pumped Raman laser achieved Watt-level output and …

Chemical pressures in crystalline solids
… of the Schrödinger electronic equation in crystalline systems and the chemical bond. The crystal of Cs2UO2Cl4 has been used with the double objective to advance in the understanding of its behavior under hydrostatic pressure solving certain controversies in relation to the rule of Badger …

Liquid crystalline multi-block copolymers
Lyotropic and thermotropic high strength liquid crystalline polymers have become an important area of research and development in polymeric, high performance materials. These materials have afforded excellent high temperature stability and high strength in the oriented direction, but not in the …

Epoxy + Liquid Crystalline Epoxy Coreacted Networks
… through in-situ polymerization of liquid crystalline epoxies (LCEs) and a non-liquid crystalline epoxy has been investigated. Three LCEs: diglycidyl ether of 4,4'-dihydroxybiphenol (DGE-DHBP) and digylcidyl ether of 4-hydroxyphenyl-4"-hydroxybiphenyl-4'-carboxylate (DGE-HHC), were …

Quantifying crystalline exhumation in the Himalaya
… and gneisses within the Higher Himalayan Crystalline between low-grade metamorphosed rocks (600-640°C/ ca. 5 kbar) of the Lesser Himalaya and Tethyan sediments. Beside tectonically driven exhumation mechanisms the channel flow model, that describes a denudation focused ductile extrusion of …

Liquid crystalline semiconductors for organic electronics
… on the synthesis and evaluation of novel liquid crystalline materials with light-emitting and or charge-transporting properties. Some of the liquid crystals (LCs) synthesised incorporate photopolymerisable diene or methacrylate end groups, situated at the peripheries of the molecular core. These …

Magnetism in crystalline rare-earth compounds
… we investigate the magnetism of a selection of crystalline mate- rials that display fascinating macroscopic properties, largely due to the complex behaviour of rare-earth ions. The technique of choice is diffraction; shown to pro- vide the most lucid of results in this field of research. Neutron …

The enzymatic solubilization of crystalline cellulose
… viride was capable of solubilizing native crystalline forms of cellulose. Enzyme activity ("hydrocellulase") was determined by measuring the decrease in turbidity of the assay reaction mixture which contained a suspended hydrocellulose substrate. Preliminary studies of "hydrocellulase" …

Reclamation and Reprocessing of Thermotropic Liquid Crystalline Polymer from Composites of Polypropylene Reinforced with Liquid Crystalline Polymer
… interest in the use of thermotropic liquid crystalline polymers (TLCPs) to reinforce thermoplastic materials. In a novel process developed by Baird and coworkers, wholly thermoplastic composites are produced via a patented, dual extrusion process. This unique process yields a fiber which …

Intrinsically Localized Lattice Vibrations in Crystalline Lattices
… the direction [111] of the Sodium Iodide (NaI) crystalline lattice. The tendency for ILMs to form at a certain center-of-mass momentum ▁q and corresponding relative momentum vector ▁k is attributed to the van-Hove singularities condition in the non-interaction two-phonon density of states …

Device Physics of Two-Dimensional Crystalline Materials
… their simplest form, existing merely in a single crystalline atomic layer and exposing the states to external controls. Triggered by graphene, the interest in a variety of other 2D crystals, such as atomically thin transition metal dichalcogenides (TMDs), has recently exploded, revising the …
