2. 21. Phase transitions in high-temperature superconductors

   Author : Jack Lidmar; KTH; []
   Keywords : Superconductivity; Vortices; Phase transitions; Strongly correlated fermions; High-temperature superconductivity; Monte Carlo simulations.; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : Thermal fluctuations and disorder strongly influence the behaviour of hightemperature superconductors. In particular the vortices play a key role in determining their properties. In this thesis the main focus lies on phase transitions, both in ultra-thin films and in three-dimensional systems, which are driven by vortex fluctuations. READ MORE

4. 22. Lipoproteomics : Environmental and Genetic Factors Affecting High-Density Lipoprotein (HDL)

   Author : Stefan Ljunggren; Mats Lindahl; Gun Wingren; Helen Karlsson; Jan Albert Kuivenhoven; Björn Dahlbäck; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Lipoprotein particles act as lipid transporters in the blood stream, and measuring cholesterol content in specific subclasses of lipoprotein particles has long been, and still is, a frequently used tool to estimate the risk of cardiovascular disease (CVD). High-density lipoprotein (HDL) is a subclass of lipoproteins often regarded as providing protection against CVD via several functions including reverse cholesterol transport and anti-inflammatory capacities.

5. 23. On Generation and Applications of High-Density Protein Microarrays

   Author : Ronald Sjöberg; Peter Nilsson; Michael Taussig; KTH; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Affinity proteomics has experienced rapid development over the last two decades and one of the most promising platforms to emerge are the protein microarrays. The combination of affinity reagents and miniaturisation enables assays for simultaneous high throughput and sensitive protein analysis. READ MORE

6. 24. High frequency electronic packaging and components : characterization, simulation, materials and processing

   Author : Christian Johansson; Mats Robertsson; Li-Rong Zheng; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dielectric loss; high frequency electrical characterization; microwave circuits; multilayer thin film technology; ORMOCER®; permittivity; printed diode; sequential build-up; silicone elastomer; Signal processing; Signalbehandling;

   Abstract : Electronic packaging continues to move towards improved performance and lower cost. Requirements of higher performance, reduced size, weight and cost of both high density interconnects and high frequency devices have led to the search for new materials, material combinations, methods, processes and production equipment.

7. 25. Ab initio Lattice Dynamics : Hydrogen-dense and Other Materials

   Author : Duck Young Kim; Rajeev Ahuja; Richard Needs; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Density functional theory; Density functional perturbation theory; Hydrogen-dense materials; Phase transition; High pressure; Ab initio lattice dynamics; Superconductivity; Quasi-particle approximation; Physics; Fysik;

   Abstract : This thesis presents a theoretical study of materials under high pressure using ab initio lattice dynamics based on density functional theory and density functional perturbation theory using both super-cell and linear response approach. Ab initio lattice dynamics using super-cell approach is applied to compare our theoretical predictions with experimental findings. READ MORE
