  2. 1. Plasma-Facing Components in Tokamaks : Studies of Wall Conditioning Processes and Plasma Impact on Diagnostic Mirrors

    Author : Álvaro García Carrasco; Marek Rubel; Marco Cecconello; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plasa-wall interactions; wall conditioning; tracers; diagnostic mirrors; ICWC; Physics; Fysik;

    Abstract : Understanding of material migration and its impact on the formation of co-deposited mixed material layers on plasma-facing components is essential for the development of fusion reactors. This thesis focuses on this topic. It is based on experiments performed at JET and TEXTOR tokamaks. READ MORE

  4. 2. Heparan Sulfate Dependent Mechanisms of Amyloidosis

    Author : Fredrik Noborn; Jin-ping Li; Ulf Lindahl; Giampaolo Merlini; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amyloidosis; Heparan sulfate; Transthyretin; Serum amyloid A; Amyloid-beta; lipoproteins; Medical Biochemistry; Medicinsk biokemi;

    Abstract : A common theme in amyloid disorders is the deposition of disease-specific protein aggregates in tissues. Amyloid proteins bind to heparan sulfate (HS), a sulfated glycosaminoglycan, and HS has been found to promote the aggregation process. READ MORE

  5. 3. Triboactive Low-Friction Coatings Based on Sulfides and Carbides

    Author : Jill Sundberg; Ulf Jansson; Jochen M. Schneider; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; coatings; thin films; tribology; tungsten disulfide; transition metal dichalcogenide; nanocomposite; TiC a-C; tribofilms; PVD; XPS; HAXPES; XRD; SEM; TEM; Raman spectroscopy; nanoindentation; Kemi med inriktning mot oorganisk kemi; Chemistry with specialization in Inorganic Chemistry;

    Abstract : For sustainable development, it is highly important to limit the loss of energy and materials in machines used for transportation, manufacturing, and other purposes. Large improvements can be achieved by reducing friction and wear in machine elements, for example by the application of coatings. READ MORE

  6. 4. Characterization of Fe-W alloys electrodeposited from environmentally friendly electrolyte

    Author : Antonio Mulone; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This work focuses on Fe-W and Fe-W/Al2O3 coatings electrodeposited from an environmentally friendly electrolyte: minimally invasive, thermodynamically stable, and without toxic compounds. Such coatings aim to be applied for protective applications and as a sustainable alternative to hard chromium coatings. READ MORE

  7. 5. Islet Amyloid Polypeptide: Interaction with Amyloid Beta, Alpha-Synuclein and BRICHOS

    Author : Ye Wang; Gunilla Westermark; Ludmilla Morozova-Roche; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amyloid; IAPP; Abeta; alpha-synuclein; Bri2 BRICHOS; luminescent conjugated oligothiophenes; Medical Cell Biology; Medicinsk cellbiologi;

    Abstract :  Amyloid, the congophilic deposits of misfolded protein, are pathological hallmarks of many common diseases, among others, Alzheimer’s disease (AD), Parkinson’s disease (PD), and type 2 diabetes (T2D). Amyloid beta (Aβ) forms senile plaques in AD, alpha-synuclein (aSyn) forms Lewy bodies and Lewy neurites in PD, islet amyloid polypeptide (IAPP) forms islet amyloid in T2D. READ MORE
