1. Ionic liquids : The solid-liquid interface and surface forces
Sammanfattning : Ionic liquids (ILs) present new approaches for controlling interactions at the solid-liquid interface. ILs are defined as liquids consisting of bulky and asymmetric ions, with a melting point below 373 K. Owing to their amphiphilic character they are powerful solvents but also possess other interesting properties. LÄS MER
2. Computer Simulations of Simple Liquids with Tetrahedral Local Order : the Supercooled Liquid, Solids and Phase Transitions
Sammanfattning : The understanding of complex condensed matter systems is an area of intense study. In this thesis, some properties of simple liquids with strong preference for tetrahedral local ordering are explored. These liquids are amenable to supercooling, and give complex crystalline structures on eventual crystallisation. LÄS MER
3. Exploring The Versatility Of Ionic Liquids : From fundamental understanding to materials inspired from ionic liquids
Sammanfattning : Ionic liquids (ILs) have gained popularity as “green” and safe replacements for conventional organic solvents. They are defined as ionic salts displaying a melting point below 100 °C. Some of their unique characteristics also include negligible vapour pressure, good electrical conductivity as well as good thermal and chemical stability. LÄS MER
4. Nanoconfined imidazolium ionic liquids
Sammanfattning : Long-chain ionic liquids are attracting interest as alternatives to their short-chain analogues as electrolytes. At the same time, they are also considered as alternatives to mesogens and conventional surfactants as templates. LÄS MER
5. On-chip terahertz characterisation of liquids
Sammanfattning : Spectroscopy at terahertz frequencies can be used in a wide range of applications including radio-astronomy, pharmaceutical manufacturing control, and the study of processes in molecular biology. Biomolecular samples should preferably be studied in their native environment, water, however, water poses extreme attenuation for THz-frequency waves, deteriorating or even impeding analysis using these waves.
