  2. 1. Hierarchical Assembly Investigations and Multiscale Characterization of Protein-based Materials : Insights from Whey Protein Nanofibrils and Recombinant Spider Silk Microspheres

    Author : Eirini Ornithopoulou; My Hedhammar; Thomas Crouzier; Christina Divne; Tim Melander Bowden; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hierarchical Assembly; Protein-based materials; Whey Protein Nanofibrils; β-Lactoglobulin; Recombinant Spider Silk; Microspheres; Biomedical Applications; Surface Biofunctionalization; Hierarkisk montering; Proteinbaserade material; Vassleprotein nanofibriller; β-Laktoglobulin; Rekombinant spindelsilke Mikrosfärer; Biomedicinska tillämpningar; Ytbiokonjugering; Biotechnology; Bioteknologi;

    Abstract : Protein-based materials, with their unique properties of combining high strength, while maintaining elasticity, and their inherent biocompatibility, hold immense potential for various applications. In order to harness these properties, we need to understand and control how protein building blocks come together to form hierarchically structured materials. READ MORE

  4. 2. Perfluorocarbon microdroplets stabilized by cellulose nanofibers : Toward ultrasound-mediated diagnostics and therapy

    Author : Ksenia Loskutova; Dmitry Grishenkov; Anna Justina Svagan; Gaio Paradossi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultrasound; acoustic droplet vaporization; phase-change contrast agent; Pickering emulsion; cellulose nanofiber; Ultraljud; akustisk droppförångning; kontrastmedel med fasförändring; Pickeringemulsion; cellulosananofiber; Teknik och hälsa; Technology and Health;

    Abstract : Ultrasound contrast agents consist of gas-filled micrometer-sized bubbles that are injectedinto the blood stream. Ultrasound contrast agents are an invaluable tool for ultrasound imaging of the cardiac muscle and highly vascularized structures such as kidneys and the liver. READ MORE

  5. 3. Nanolatexes: a versatile toolbox for cellulose modification

    Author : Alexandros Efraim Alexakis; Eva Malmström; Justin Zoppe; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanolatexes; RAFT; PISA; adsorption; cellulose; modification; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Cellulosic materials are widely used in our everyday lives, ranging from paperand packaging to biomedical applications. However, in most applications, cellulose must coexist with hydrophobic polymers which can be challenging due to its hydrophilic character. This has encouraged the exploration of chemical and physical modifications of cellulose. READ MORE

  6. 4. Finite Element simulations: computations and applications to aerodynamics and biomedicine

    Author : Massimiliano Leoni; Johan Hoffman; David Kamensky; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; radiofrequency ablation; finite elements; numerical simulations; partial differential equations; biomedical applications; HPC; Computer Science; Datalogi;

    Abstract :   Partial Differential Equations describe a large number of phenomena of practical interest and their solution usually requires running huge simulations on supercomputing clusters.  Especially when dealing with turbulent flows, the cost of such simulations, if approached naively, makes them unfeasible, requiring modelling intervention.

  7. 5. High-resolution biomedical phase-contrast tomography

    Author : William Twengström; Hans Hertz; Anna Burvall; Marco Stampanoni; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; x-ray; x-ray imaging; biomedical; phase contrast; tomography; zebrafish; coronary artery; virtual histology; ring artifacts; phase retrieval; mummy; Fysik; Physics;

    Abstract : Improved three-dimensional biomedical imaging can give a better understanding of tissue structure, growth and diseases. Most present imaging techniques that provide cellular spatial resolution are based on visible or infrared light. These methods cannot image deeper than a millimeter into tissue. READ MORE
