  2. 6. Controlling the Pore Size and Morphology of Mesoporous Silica

    Author : Emma M. Johansson; Magnus Odén; José M. Cordoba; Niklas Hedin; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Mesoporous silica with a hexagonally ordered pore structure (SBA-15) has been synthesized. Through variations in the synthesis conditions several morphologies, such as fibers, sheets and separate rods, have been realized. READ MORE

  4. 7. Endovascular occlusion methods in non-traumatic cardiac arrest

    Author : Emanuel M. Dogan; Tal M. Hörer; Kristofer F. Nilsson; Birger Axelsson; Lars Wik; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac arrest; cardiopulmonary resuscitation; REBOA; intra-aortic balloon pump;

    Abstract : Approximately 10% of out-of-hospital cardiac arrest patients survive to hospital discharge. An important factor for survival is perfusion to the coronary and cerebral circulations during cardiopulmonary resuscitation (CPR). READ MORE

  5. 8. The Location and Variability of Southern ocean Fronts

    Author : Robert M. Graham; Agatha M. de Boer; Jonas Nycander; Qiong Zhang; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The location of fronts has a direct influence on both the physical and biological processes in the Southern Ocean. Moreover, the Subtropical Front (STF) is believed play a key role in the global climate system. READ MORE

  6. 9. Hydrophobic surfaces: Effect of surface structure on wetting and interaction forces

    Author : Petra M Hansson; Per M. Claesson; Agne Swerin; Adam C Simonsen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrophobic surface; superhydrophobic surface; atomic force microscopy; surface forces; capillary forces; cavitaion; surface roughness; friction; wetting; confocal Raman; contact angles; surface preparation; Langmuir-Blodgett;

    Abstract : The use of hydrophobic surfaces is important for many processes both in nature and industry. Interactions between hydrophobic species play a key role in industrial applications such as water-cleaning procedures and pitch control during papermaking but they also give information on how to design surfaces like hydrophobic mineral pigments.

  7. 10. Unsaturated Fatty Acids in Alkane Solution : Adsorption and Tribological Properties

    Author : Sarah M. Lundgren; Per M. Claesson; Hugh Spikes; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi;

    Abstract : Fatty acids and blends of fatty acids are used as friction modifiers and anti-wear additives in diesel fuels. A large part of some fatty acid blends are unsaturated fatty acids. Even though fatty acids have been thoroughly investigated, the adsorption and tribological behaviour of unsaturated fatty acids are no fully understood. READ MORE
