  1. 21. Residual and critical saturation in geological storage of CO2 : results from field studies, pore-network modelling and laboratory experiments

    Författare :Ramin Moghadasi; Auli Niemi; Philip Ringrose; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geological CO2 storage; Residual trapping; Gas remobilization; Field experiment; Numerical modelling; Pore-network modelling; Pore-scale imaging;

    Sammanfattning : Geological storage of CO2 in deep saline aquifers is a promising technology in the combat to reduce the atmospheric emissions of CO2. A critical component in this solution is the estimation of aquifer’s in situ capability to store CO2. LÄS MER

  3. 22. Source and drain engineering in SiGe-based pMOS transistors

    Författare :Christian Isheden; Mikael Östling; Simon Deleonibus; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; SiGe; source drain; shallow junctions; pMOS; process integration; CVD; epitaxy; etching; Ni silicide; contact resistivity; Elektronik; Electronics; Elektronik;

    Sammanfattning : A new shallow junction formation process, based on selective silicon etching followed by selective growth of in situ B-doped SiGe, is presented. The approach is advantageous compared to conventional ion implantation followed by thermal activation, because perfectly abrupt, low resistivity junctions of arbitrary depth can be obtained. LÄS MER

  4. 23. Tight juntion in ovarian surface epithelium and epithelial ovarian tumors

    Författare :Yihong Zhu; Göteborgs universitet; []
    Nyckelord :junction; claudin; ovarian surface epithelium; epithelial ovarian tumor; TGF-?1;

    Sammanfattning : Epithelial ovarian cancer originating from ovarian surface epithelium (OSE) is the most lethal type of gynecological cancer among women worldwide. The poor understanding of the cellular and molecular events associated with ovarian carcinogenesis leads to difficulties in early diagnosis and in efficient treatment. LÄS MER

  5. 24. Predictive and prognostic biomarkers in oral tongue squamous cell carcinoma

    Författare :Michael Ryott; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Oral tongue squamous cell carcinoma (OTSCC) is an aggressive disease frequently associated with poor prognosis due to the high risk of regional failure and mortality rates have been practically unchanged in Sweden the last fifty years, despite advancements in both diagnostics and treatment. Today we lack means to assess the biological aggressiveness of each individual tumor which varies largely. LÄS MER

  7. 25. The rational design of lithium insertion materials for battery applications

    Författare :Helena Berg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; cathode materials; lithium manganese oxide; in situ neutron diffraction; Rietveld refinement; band-structure calculations; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : The transition-metal oxide spine1 LiMn2O4 is a promising cathode material for high-capacity lithium-ion batteries. Structure-property relationships pertaining to the electrochemical cycling behaviour of LiMn2O4 have been studied. LÄS MER
