21. Surface tension-driven flow in soft porous materials — An investigation of the mechanism of capillary flow in microchannels of hydrogels
Sammanfattning : Spontaneous spreading of liquids in porous materials is of great industrial relevance and occurs in, for example, diapers, fabrics, paper or paint. Often, it is necessary to manipulate the spreading rate of liquids to result in the desired mass transport, for example to soak up large liquid volumes, as in a diaper. LÄS MER
22. High aspect ratio microsystem fabrication by ion track lithography
Sammanfattning : The microsystem processing of today is based on an assortment of diverse and contrasting fabrication techniques, sprung from the microelectronic industry. Microsystem technology has primarily been developed to meet the demands for scaled down low-cost sensor and actuator systems. These devices are based on a number of contrasting principles, e.g. LÄS MER
23. Estrogen receptors in skeletal muscle : expression and activation
Sammanfattning : There are two estrogen receptors (ERs), ERalpha and ERbeta, which are ligand activated transcription factors. Estrogen, which exerts its effect via ERs, is not only a female reproductive hormone, but acts almost ubiquitously in the human body and is involved in physiological and pathological states in both males and females.

24. Development of Methods in CE, CE-MS and MS/MS : Applications in Pharmaceutical, Biomedical and Forensic sciences
Sammanfattning : Capillary electrophoresis-mass spectrometry has been used successfully for the analysis of a wide range of analytes such as chiral local anaesthetics, sulphonated reactive dyes and endogenous neurotransmitters and neuropeptides.The partial filling technique was used in CE-MS for chiral separation of bupivacaine and ropivacaine using the non-volatile selector β-cyclodextrin.

25. Physicochemical and Biopharmaceutical Characterisation of Small Drug Molecules by Capillary Electrophoresis
Sammanfattning : Capillary Electrophoresis (CE) was explored as a means for physicochemical and biopharmaceutical characterisation of small drug molecules. Special attention was paid to the characterisation of acid-base and lipophilic properties of drug compounds by analysing their migration behaviour in different CE systems. LÄS MER
