Sammanfattning : Experimental studies of laser-driven acceleration of charged particles, in particular electrons and protons, are described in this dissertation. Tightly focused femtosecond laser pulses with intensities exceeding 1018 W/cm2 were used to accelerate charged particles to high energies over distances of a few millimeters. LÄS MER
2. Residual Trapping in Geological Storage of CO2 : Determination from Field Experiments and Data Analysis Using Numerical Modeling
Sammanfattning : Geological storage of CO2 in deep saline aquifers is one of the methods to mitigate the release of this greenhouse gas into the atmosphere. The efficiency of this solution can be improved by better understanding of the relevant trapping processes, as well as by improving available injection techniques and developing tools for more accurate site characterization.

3. Trapping Tyrosine Z : Exploring the Relay between Photochemistry and Water Oxidation in Photosystem II
Sammanfattning : Photosystem II is unique! It remains the only enzyme that can oxidize water using light as energy input. Water oxidation in photosystem II is catalyzed by the CaMn4 cluster. The electrons extracted from the CaMn4 cluster are transferred to P680+ via the tyrosine residue D1-Tyr161 (YZ). LÄS MER
Sammanfattning : Herein a method that uses acoustically resonating glass capillaries and enables non-contact capture of micron-sized bioparticles, i.e. acoustic trapping, is described. A miniaturized ultrasonic transducer is used to locally actuate a cross-sectional resonance in the capillary. LÄS MER
Sammanfattning : Analysis methods are currently being miniaturized in order to save time and money while achieving higher sensitivities. The ultimate goal is to create a lab-on-a-chip where all analysis steps and instruments can be automated and integrated into a single chip. LÄS MER
