1. 6. The amyloid : structure, properties and application

   Författare :Mantas Malisauskas; Ludmilla Morozova-Roche; Fabrizio Chiti; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amyloid; oligomers; AFM; cytotoxicity; biotemplating; lysozyme; Biochemistry; Biokemi;

   Sammanfattning : Protein aggregation, leading to the formation and depositions of amyloids, is a cause for a number of diseases such as Alzheimer’s and Creutzfeld-Jacob’s disease, systemic amyloidoses, type II diabetes and others . More than 20 proteins are associated with protein misfolding diseases and even a larger number of proteins can self-assemble into amyloid in vitro. LÄS MER

3. 7. Amyloids here, amyloids there…What’s wrong with them?

   Författare :Anna Gharibyan; Ludmilla Morozova-Roche; Tuomas Knowels; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Amyloids; oligomers; fibrils; cytotoxicity; Alzheimer s disease; Aortic stenosis; S100A9; medicinsk biokemi; Medical Biochemistry;

   Sammanfattning : Amyloid formation is inherent property of proteins which under certain circumstances can become a pathologic feature of a group of diseases called amyloidosis. There are about 30 known human amyloidosis and more than 27 identified proteins involved in these pathologies. LÄS MER

4. 8. Controlled Degradation of Polyester-Ethers Revealed by Mass Spectrometry Techniques

   Författare :Anders Höglund; Ann-Christine Albertsson; Jukka Seppälä; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Degradation products; biocompatibility; -caprolactone; 1; 5-dioxepan-2-one; 6-hydroxyhexanoic acid; 3- 2-hydroxyethoxy propanoic acid; oligomers; Polymer chemistry; Polymerkemi;

   Sammanfattning : The use of degradable biomedical materials in e.g. tissue engineering and controlled drug delivery has changed medical science during recent decades. The key question is to adapt the material with respect to mechanical properties, surface characteristics, and degradation profile to suit its intended application. LÄS MER

5. 9. Conjugated materials for organic electronic devices : photoelectron spectroscopy studies

   Författare :Wojciech Osikowicz; William R. Salaneck; Linköpings universitet; []
   Nyckelord :conjugated polymers; oligomers; electronic structure; photoelectron spectroscopy; UPS; XPS;

   Sammanfattning : Conjugated materials have attracted great attention since the discovery of high conductivity in donor and acceptor doped polyacetylene over two decades ago. The discoveries mentioned below caused, however, that the interest begun to shift towards their pristine semi-conducting state. LÄS MER

7. 10. Photon Upconversion through Triplet-Triplet Annihilation: Towards Higher Efficiency and Solid State Applications

   Författare :Damir Dzebo; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; solar energy conversion; triplet-triplet annihilation; energy transfer; fluorescence anisotropy; anti-stokes; photon upconversion; excited state; porphyrins; photochemistry; photophysics; delayed fluorescence; dendrimers; anthracene; oligomers; spectroscopy;

   Sammanfattning : The sun is the only renewable energy source that can accommodate humanity’s energyneeds today and in the foreseeable future. The sunlight reaching the planet’s surfaceis filtrated through the atmosphere, reducing its UV-light intensity in the 300-400 nmrange, which indeed can be harmful to life as we know it in too large doses.
