1. Chirality in Crystal Engineering
Sammanfattning : Crystal engineering combines supramolecular chemistry with solid state chemistry. The goal is to make molecular entities assemble into predefined structures with specific properties. At the same time much research is focused on the understanding of the intermolecular interactions governing the crystallisation process. LÄS MER
2. A Theoretical Study: The Connection between Stability of Single-Walled Carbon Nanotubes and Observed Products
Sammanfattning : Over the past 20 years’ researchers have tried to utilize the remarkable properties of single-walled carbon nanotubes (SWCNTs) to create new high-tech materials and devices, such as strong light-weight composites, efficient electrical wires and super-fast transistors. But the mass production of these materials and devices are still hampered by the poor uniformity of the produced SWCNTs. LÄS MER
3. Creating Optical Activity: Total Spontaneous Resolution and Viedma Ripening
Sammanfattning : The creation of optical activity has been considered as something impossible even though reports of such creation via total spontaneous resolution since the 1940´s have been published. More recently Viedma ripening have been developed that also produce enantiopure bulk product. Both methods are examples of absolute asymmetric synthesis i.e. LÄS MER
4. Versatile Association Behavior in Mixtures of Oppositely Charged Amphiphiles : From DNA-Like Assembly of Supramolecular Helices to Coacervation in Chiral Surfactant Systems
Sammanfattning : As biological surfactants, bile salts (BSs), play important roles in biological processes, i.e., food digestion, but also in BS-related diseases, as well as in applications. LÄS MER
5. Chiral Recognition by Means of Mass Spectrometry
Sammanfattning : This thesis is based on experimental studies of chiral ions in gas-phase. Electrospray ion source platform (Stockholm University) and commercially available Quadrupole Time-of-Flight mass spectrometer have been used in our studies. LÄS MER
