  2. 11. Nano-particulate Silica Hydrogels Imaged in 2D and 3D using TEM: Effects of local pore structure on mass transport and applications in aggregation dynamics

    Author : Charlotte Hamngren Blomqvist; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; silica gel; colloidal silica gel; interconnectivity; nanoporous; electron tomography; silica nanoparticle gel; mass transport; nanostructure; accessible volume fraction; 3D structure;

    Abstract : Porous materials are frequently used in everyday applications including food science, pharmaceuticals, fuel cell membranes, batteries and solar cells. A key aspect in these porous materials is how their micro- and nano-structure affect the internal transport of for example water, particles or charges. The transport is a three-dimensional process.

  4. 12. 31 P- and 65 Cu- solid state NMR studies of Cu(I) di-alkyl-dithiophosphates : complex Formation Mechanism on Synthetic Chalcocite Surfaces

    Author : Daniela Rusanova; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : Alkyl substituted derivatives of dithiophosphoric acid are frequently used as collectors in froth flotation enrichment of copper sulfide ores. Due to interaction between Cu atoms at the surface and thiol collector molecules, a concomitant adsorption process occurs on the mineral surface. READ MORE

  5. 13. Quantitative cardiac 15O-water PET : Assessment of left-ventricular function, remodeling, and impact of patient motion

    Author : Jonny Nordström; Mark Lubberink; Jens Sörensen; Hendrik J Harms; Stephan Nekolla; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; positron emission tomography PET ; 15O-water; myocardial blood flow; cardiac remodeling; patient motion;

    Abstract : International guidelines advocate the use of noninvasive cardiac imaging as the initial diagnostic test for coronary artery disease, the global leading cause of death according to the world health organization. Within the wide spectrum of cardiac imaging, 15O-water PET is the gold standard for noninvasive quantification of myocardial blood flow (MBF). READ MORE

  6. 14. Brain imaging in extremely preterm infants : relations to perinatal factors and outcome

    Author : Georgios Alexandrou; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The survival of extremely preterm infants has improved over the last decades along with the advances in perinatal care. These immature children are born at a vulnerable stage of brain development, before entering the third trimester of gestation, and are at an increased risk for brain injuries, atypical brain development and subsequent adverse neurodevelopment.

  7. 15. Targeting MYC and CDK2 in cancer : impacts on senescence, apoptosis and immune modulation

    Author : Wesam Bazzar; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Cancer is a disease in which cells acquire the ability to divide uncontrollably and invade other tissues. An important component of this process is the activation of oncogenes and inactivation of tumor suppressor genes. READ MORE
