  2. 21. Superparamagnetic iron oxide nanoparticles, a novel tracer in breast cancer surgery

    Author : Abdi-Fatah Hersi; Staffan Eriksson; Fredrik Wärnberg; Andreas Karakatsanis; Thorsten Kühn; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast Cancer; superparamagnetic iron oxide nanoparticles; SPIO; magnetic seed; magnetic surgery; sentinel node; sentinel node biopsy; nonpalpable; ductal carcinoma in situ; DCIS; Surgery; Kirurgi;

    Abstract : The most common surgical choice of treatment in breast cancer is breast-conserving surgery (BCS) together with sentinel lymph node biopsy (SNB). Around 10% of breast cancer diagnosis are ductal carcinoma in situ (DCIS). Superparamagnetic iron oxide nanoparticles (SPIO) are a novel tracer for sentinel lymph node (SN) detection. READ MORE

  4. 22. Proton Relaxation Properties of a Particulate Iron Oxide MR Contrast Agent in Different Tissue Systems : Implications for Imaging

    Author : Atle Bjørnerud; Graham A. Wright; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Iron oxide nanoparticles; USPIO; NC100150 Injection; water exchange limited relaxation; MR perfusion imaging.; Onkologi; Oncology; Onkologi; radiologi; Radiology;

    Abstract : Knowledge of the relationship between in vivo contrast agent concentration and magnetic resonance (MR) signal response is an important requirement in contrast enhanced MR imaging in general and in MR based perfusion imaging in particular. This relationship is a complex function of the properties of the contrast agent as well as the structure of the target tissue. READ MORE

  5. 23. Following nanoparticle self-assembly in real-time : Small-angle X-ray scattering and quartz crystal microbalance study of self-assembling iron oxide nanocubes

    Author : Martin Kapuscinski; Lennart Bergström; Niklas Hedin; Andrei Petukhov; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; self-assembly; mesocrystal; time-resolved; small-angle X-ray scattering; iron oxide nanocubes; QCM-D; Materials Chemistry; materialkemi;

    Abstract : Self-assembly of nanoparticles is a widely used technique to produce nanostructured materials with crystallographic coherence on the atomic scale, i.e. mesocrystals, which can display useful collective properties. This thesis focusses on the underlying mechanism and dynamics of mesocrystal formation by using real-time techniques. READ MORE

  6. 24. Geophysical 3D models of Paleoproterozoic Iron Oxide Apatite mineralization’s and Related Mineral Systems in Norrbotten, Sweden

    Author : Oskar Rydman; Maxim Smirnov; Thorkild Maack Rasmussen; Tobias Bauer; Niklas Juhojuntti; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geophysics; Magnetotellurics; 3D Inversion modelling; Classification; Potential fields; Mineral system; Petrophysics; mineral exploration; common earth modeling; iron oxide-apatite; Northern Norrbotten ore province; Tillämpad geofysik; Applied Geophysics;

    Abstract : The Northern Norrbotten ore district hosts a multitude of Sweden’s mineral deposits including world class deposits such as the Malmberget and Kirunavaara Iron oxide apatite deposits, the Aitik Iron oxide copper gold deposit, and a multitude of smaller deposits. Northern Norrbotten has been shaped by tectonothermal events related to the evolution of the Fennoscandian Shield and is a geologically complex environment. READ MORE

  7. 25. Transition metal oxide surfaces : Surface structures and molecular interaction

    Author : Markus Soldemo; Jonas Weissenrieder; Mats Göthelid; Sarp Kaya; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Abstract : Metal oxides are both corrosion products and useful materials with a wide range of applications. Two of the most used metals today are iron and copper. In this thesis, surface structures and molecular interaction with surfaces of iron oxides and copper oxides are studied using spectroscopy and microscopy methods. READ MORE
