22. On the processing of starch consolidated high speed steel - Microstructure and tribological properties
Sammanfattning : This thesis focuses on processing of high speed steel (HSS) powder into components using starch consolidation (SC) and supersolidus liquid phase sintering (SLPS). The work consists of four parts. First, the possibilities and constrains of the SC process are investigated and the role of starch in the green body fabrication clarified. LÄS MER
23. New approaches to preparation of macroporous monoliths for use in liquid chromatography
Sammanfattning : High performance liquid chromatography (HPLC) is one of the major techniques in separat-ion sciences. Faster separation and higher efficiency are required to meet ever-growing demands. Despite numerous studies and achievements on improving mass transfer in particulate packings discontinuity seems to be the cornerstone drawback in their development. LÄS MER
24. Investigations of Optical Properties and Photo-Alignment in Bistable Nematic Liquid Crystal Displays
Sammanfattning : In recent years portable electronic devices, such as mobile phones and personal digital assistants, have increased the demand for high performance displays with low power consumption. An interesting candidate with the potential of fulfilling these demands is the reflective single-polarizer surface controlled bistable twisted nematic liquid crystal display. LÄS MER
25. Small-Scale Sample Handling for Studies of Liquid Crystals and Lipid-Based Soft Matter
Sammanfattning : In the field of sensing in general and biosensing in particular, there is a growing need for integratingminiaturised senor elements in microfluidic systems. The advantages are several, some of which being that the consumption of, often very expensive, sample material can be reduced; sampleexchange can be optimized; sensor performance in terms of detection limits can be improved and phenomena occurring on a very small, and even single-molecule, scale can be studied.
