1. 1. Drug Diffusion and Nano Excipient Formation Studied by Electrodynamic Methods

   Författare :Ulrika Brohede; Maria Strømme; Göran Frenning; Hans Leuenberger; Uppsala universitet; []
   Nyckelord :Functional materials; drug release; electrodynamic methods; diffusion; Funktionella material;

   Sammanfattning : New smart drugs demand new smart drug delivery systems and also new smart analysis methods for the drug delivery process and material characterization. This thesis contributes to the field by introducing a new electrodynamic approach for studying the drug diffusion proc-esses as well as the formation of a new type of drug delivery systems, the so called mesoporous nano excipients.

3. 2. Pushing methods for plasma simulations into the QED regime

   Författare :Erik Karl Wallstén Wallin; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LWFA; nonlinear dynamics; plasma; Manley-Rowe; particle-in-cell; synchrotron radiation; radiation reaction;

   Sammanfattning : The interaction between a super-intense laser pulse, with intensity up to 10²² W/cm², and a plasma opens new regimes of physics, with new questions and more demand on existing numerical tools. Relativistic and quantum effects which are negligible for lower laser intensities become important and must be properly modelled to generate reliable predictions. LÄS MER

4. 3. Electrodynamic and Mechanical Spectroscopy Method Development and Analysis Relating to Materials with Biotechnological Applications

   Författare :Ken Welch; Maria Strømme; Ragnar Ek; Bengt-Erik Mellander; Uppsala universitet; []
   Nyckelord :Engineering physics; Teknisk fysik;

   Sammanfattning : Materials with biotechnological applications and materials that interact with the biological environment play an ever increasing role in our lives and society. In order to be able to tailor specific properties of these materials to suit their intended applications, it is important to gain a deeper understanding of the relationship between the material structure and its function.

5. 4. Pd-nanoalloys for hydrogen sensing: Multiscale modeling of thermodynamic and optical properties

   Författare :Pernilla Ekborg-Tanner; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pd-alloys; hydrogen sensing; surface segregation; nanoplasmonics; nanoalloys;

   Sammanfattning : Hydrogen sensing based on Pd nanoalloys has shown great promise in the past decades and could potentially be part of a solution that enables a safe future hydrogen economy. There are, however, remaining challenges related to, e.g., long-term stability and a need for further optimization of these systems. LÄS MER

7. 5. Alloy Plasmonics - Fundamentals and Applications

   Författare :Christopher Tiburski; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; sensing; gold-palladium; nanothermometry; palladium-hydride; nanoalloys; photothermal; plasmonics; CO oxidation; heterogeneous catalysis; dielectric function;

   Sammanfattning : Alloys have for a long time been important in the development of our society; from the Bronze Age, where man learned how to alloy copper with tin, to today, where many products are made of steel and aluminum alloys. Similarly, but maybe not as generally well known, alloys have lately been proposed as a new paradigm in nanophotonics, to tailor optical properties of nanomaterials that find applications within telecommunication, sensing, or biotechnology.
