1. 1. Macrophage-material surface interactions

   Författare :Christina Gretzer; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Apoptosis; biomaterials; cell-cell interactions; cell-material interactions; cytokines; differentiation; fibrinogen; hydrogen peroxide; LPS; monocytes; particles;

   Sammanfattning : Material surface-stimulated activation of the macrophage and the release of mediators has been suggested to be an important factor for inflammation and tissue regeneration around biomedical implants. Macrophage interactions with particles released from implants as well as macophage-bacteria interactions are also involved in implant loosening processes. LÄS MER

3. 2. MATTER-ANTIMATTER INTERACTIONS : The hydrogen-antihydrogen system and antiproton-matter interactions

   Författare :Henrik Stegeby; Roland Lindh; Dage Sundholm; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; antimatter; antiproton; matter-antimatter interactions; hydrogen-antihydrogen system; Kemi med inriktning mot kvantkemi; Chemistry with specialization in Quantum Chemistry;

   Sammanfattning : Ever since antiparticles were discovered their nature has been something of a mystery. They were postulated to be identical to regular particles except for having opposite charge, but this would imply that an equal amount of antiparticles and particles should have been created at the beginning of time.

4. 3. Towards novel applications for biomolecular interactions at surfaces

   Författare :Pernilla Söderberg; Karl Hult; Linnéuniversitetet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; molecular recognition; interactions; phage display; biomolecular interactions; phage; adenine; influenza virus replication; oseltamivir; imprinted polymers.;

   Sammanfattning : The focus of this thesis has been to examine two new concepts involving the interaction of biological agents with synthetic material surfaces.The feasibility of deploying phage display techniques for the screening of materials in non-biological media was examined in two studies.

5. 4. Inverse Modeling of Cloud – Aerosol Interactions

   Författare :Daniel Partridge; Johan Ström; Kari Lehtinen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stratocumulus; marine; cloud; aerosol; interactions; MCMC; inverse modeling; droplet closure; global sensitivity; Atmosphere and hydrosphere sciences; Atmosfärs- och hydrosfärsvetenskap; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : The role of aerosols and clouds is one of the largest sources of uncertainty in understanding climate change. The primary scientific goal of this thesis is to improve the understanding of cloud-aerosol interactions by applying inverse modeling using Markov Chain Monte Carlo (MCMC) simulation. LÄS MER

7. 5. Bio-Nano Interactions : Synthesis, Functionalization and Characterization of Biomaterial Interfaces

   Författare :Yixiao Cai; Xia Wei; Mikael Karlsson; Martin Andersson; Uppsala universitet; []
   Nyckelord :Bioactive surfaces; nanocrystalline diamond; hydroxyapatite; protein secondary structure; protein absorption; auditory neurons; single crystalline rutile; nano morphology; surface functionalisation; in vitro biomineralisation; translucent nano-ceramics; bio-window material; material characterisation.; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

   Sammanfattning : Current strategies for designing biomaterials involve creating materials and interfaces that interact with biomolecules, cells and tissues.  This thesis aims to investigate several bioactive surfaces, such as nanocrystalline diamond (NCD), hydroxyapatite (HA) and single crystalline titanium dioxide, in terms of material synthesis, surface functionalization and characterization.
