  3. 2. Secondary Nucleation in Amyloid Formation

    Författare :Mattias Törnquist; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alzheimer s disease; amyloid; Ab42; aggregation mechanism; aggregation kinetics; secondary nucleation; Protein misfolding;

    Sammanfattning : Research into Alzheimer's disease is still hampered by a lack of fundamental understanding of the underlying mechanisms. While the aggregation of the amyloid β peptide (Aβ) into amyloid fibrils is highly implicated as a key factor in the disease, the molecular nature of its involvement has proven complex and elusive.

  4. 3. Water Condensation and Freezing in the Atmosphere: Exploring Deliquescence and Ice Nucleation

    Författare :Dimitri Castarède; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hygroscopicity; Deliquescence; Atmosphere; Particles; Ice Nucleation; Ice Nucleation Chamber;

    Sammanfattning : Atmospheric aerosols play key roles in numerous atmospheric processes. They affect human health, are substrates and components for atmospheric chemistry, and via their contribution to clouds affect the water cycle and the energy balance of the planet. LÄS MER

  5. 4. Understanding secondary nucleation of the amyloid β peptide

    Författare :Dev Thacker; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alzheimer s disease AD ; A beta 1-42; Amyloid aggregation; secondary nucleation;

    Sammanfattning : Alzheimer’s Disease (AD) is a devastating neurodegenerative disease associated with massive neuronal cell death during its pathology. The involvement of the amyloid β 42 (Aβ42) peptideand its role in neurotoxicity is now well established. LÄS MER

  7. 5. Graphene Oxide Technology to Advance the Performance of Poly(lactic acid) Materials

    Författare :Huan Xu; Minna Hakkarainen; Jean-Marie Raquez; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Poly lactic acid ; Graphene Oxide; Stereocomplex; Nucleation Mechanism; Crystalline Morphology; Filler Structure; Mechanical Properties; Gas Barrier; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : In the past two decades, a burgeoning biorefinery concept has grown in concert with the materials science, contributing to the rise of biobased materials that respect environment and are versatile for various applications. An excellent example is poly(lactic acid) (PLA) that exhibits high strength and desirable degradability. LÄS MER
