Transport properties of graphite-loaded composites in liquid and solid states
Composites, either in solid state or liquid state, are widely used to improve the transport properties of the matrix phase in the composites. For instance, high thermal conductivity particles are frequently added into heat transfer liquids, forming colloidal suspensions sometimes also called …

Binding anions using simple neutral molecules
… coordination properties in both the solution and solid states. A set of ten urea/thiourea linked indole/carbazole groups were found to have high affinities for a variety of oxo-anions in highly competitive DMSO solutions. Of these receptors, the diindolylurea motif was found to be excellent for …

Dopant effects on solid-solid transitions in atomic clusters
… examines the effect of a single dopant on the solid-solid transitions of LJ clusters characterised by a double-funnel energy landscape. The incorporation of a dopant atom into LJ38 or LJ31 offers a tunable change in the transition temperature between two competing solid states by influencing …

Development Of Inlet And Vacuum Ionization Methods For Characterization Of Biological Materials By Mass Spectrometry
… electrospray ionization (ESI)-like ions from the solid or liquid states, operating from atmospheric pressure (AP) or vacuum, without the use of voltage or the necessity of high energy input such as a laser or particle beam. The fundamental aspects were probed for better understanding of the novel …

Heat and fluid flow analysis in a molten CuCl heat exchanger
… CuCl undergoes, as it cools down from liquid to solid states. This thesis presents a new model that predicts the fluid flow and heat transfer in a direct contact heat exchanger, designed to recover the heat from molten CuCl, through the physical interaction between CuCl droplets and air. …

Rheology and Collective Behavior in Living Tissue
… can transition from a soft fluid-like state to a solid-like state, with dynamics that share many features with glass transitions. While a coherent picture has begun to form connecting the microscopic mechanisms that drive this transition with macroscopic observables, much less is known of its …

Characterization of native and bypass human coronary artery plaque deposits from the same heart: investigation of the chemical form of calcium in human coronary artery plaque deposits
… coupled plasma mass spectrometry (ICPMS), solid-state nuclear magnetic resonance (NMR), high performance liquid chromatography (HPLC), etc. The results from the ICPMS technique showed that the concentrations of Ca and P varied widely in the bypass arteries. In contrast, the concentrations …

Design, Synthesis and Self-assembly of Amphiphilic Cyclodextrin-Based Materials for Enhanced Ion Conduction and Drug Encapsulation
… their associated mesophases commonly formed in solid states as well as characterization methods. A brief review on amphiphilic CD-based liquid crystalline materials during recent years has also been provided. Following the introduction, Chapter 2 details the synthesis of family of amphiphilic …

Pseudorotaxanes and Supramolecular Polypseudorotaxanes Based on the Dibenzo-24-Crown-8/Paraquat Recognition Motif
… cationic guest and its PF6- counterions in the solid states of the latter four examples, but not in the former. The complexes based on the new dibenzo-24-crown-8/paraquat recognition motif are thus different from the complexes based on two old recognition motifs: the BPP34C10/BMP32C10-paraquat …

Transport studies of reentrant integer quantum Hall states forming in the two-dimensional electron gas
… odd-denominator fractional quantum Hall states have enriched many-body physics with important concepts such as fractional statistics and composite fermions. The subsequent discovery of the enigmatic even-denominator ν=5/2 fractional quantum Hall state has led to more interesting concepts …

Viscoelastic and fracture behaviour of polyolefin based nanocomposites
… composites, both in the molten and in the solid states, and on their fracture properties. In the first part of the work, a detailed microstructural characterization was performed to assess the different morphologies and surface properties of the utilized powders. Furthermore a detailed …
