2. 1. Protein-protein interactions in model systems : design, control of catalytic activity and biosensor applications

   Author : Johan Rydberg; Lars Baltzer; Joel Schneider; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Protein interactions; design; catalysis; biosensors; hybride materials; nanoparticles; Kemi; Chemistry; Kemi;

   Abstract : This thesis describes the design of polypeptides, unordered in the monomeric state but capable of folding into helix-loop-helix motifs and dimerise to form four-helix bundles. The goal of the design was to encode them with the capacity to form dimers highly selectively and the ability to carry out molecular functions in the folded state but not in the unordered state, and thus to establish a molecular link between recognition and function.

4. 2. Studies of an elusive element : processes that influence the net retention of mercury in lake sediments and peatlands

   Author : Johan Rydberg; Richard Bindler; Carl Lamborg; Umeå universitet; []
   Keywords : Mercury; retention; lake sediments; peatlands; environmental archives; sedimentation; diagenesis; vegetation; permafrost; Environmental Science; miljövetenskap;

   Abstract : Because of its toxic nature mercury is a threat to both wildlife and human health, and thus, it is an element of concern in the environment. Currently much of the mercury emitted to the atmosphere is derived from anthropogenic sources – both direct emissions and re-emission of already deposited anthropogenic mercury. READ MORE

5. 3. Integrated Communications and Thermal Management Systems for Microsystem-based Spacecraft : A Multifunctional Microsystem Approach

   Author : Henrik Kratz; Anders Rydberg; Johan Köhler; Pelle Rangsten; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; nanospacecraft; MST; MEMS; silicon; communication; thermal management; antenna; paraffin; PCM; multifunctional; microsystems; Elektronik; Electronics; Elektronik;

   Abstract : This thesis explores the potential of multifunctional silicon-based microsystems for advanced integrated nanospacecraft (AIN). Especially, multifunctional microsystems with the coexistant functions of communications and thermal management implemented in multilayer silicon stacks are approached with systems study. READ MORE

6. 4. Characterisation and Applications of Ultrashort Extreme Ultraviolet Pulses

   Author : Johan Norin; Atomfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ultrashort pulses; pulse characterisation; sidebands; interferometry; Atom- och molekylärfysik; acetylene; Atomic and molecular physics; High-order harmonics; XUV; Fysicumarkivet A:2002:Norin;

   Abstract : When a strong laser field interacts with free atoms, harmonics up to very high orders are created. This extreme ultraviolet (XUV) radiation has interesting properties, such as spatial and temporal coherence, short pulse duration and high brightness. This thesis concentrates on the temporal aspects of this radiation. READ MORE

7. 5. Excited States in Negative Ions

   Author : Johan Rohlén; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Negative Ions; Photodetachment; Atomic Physics; Experimental Physics;

   Abstract : This thesis covers experimental studies of atomic negative ions with the main goal of increasing our fundamental understanding of these fragile quantum systems. Comparisons of measurements and calculations have been used to increase our understanding of these highly correlated, yet simple, systems. READ MORE
