  1. 31. Using Molecular Dynamics Simulations to Explore Critical Property Relationships in Polymer Electrolytes : Polarity, Coordination, Ionic transport, Ion-pairing, and Ion-ion Correlations

    Författare :Harish Gudla; Daniel Brandell; Chao Zhang; Andreas Heuer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Solid polymer electrolytes; molecular dynamics simulations; solvent polarity; ion-pairing; ion coordination; ion transport mechanisms; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : While ion transport in solid polymer electrolytes (SPEs) has been explored for decades, there still remains controversies about its fundamental properties, often correlated with gaps between experimental and computational studies. Using molecular dynamics simulations to understand the complex transport mechanisms and also to fill these gaps is the main goal of this thesis. LÄS MER

  2. 32. In vitro studies on cholecystokinin-induced inhibition of acid formation in gastric glands

    Författare :Per Bengtsson; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The design of methods useful for the preparation of viable glands and cells from the gastric mucosa allowed detailed studies on the mechanisms that regulate gastric acid secretion. The preparation of rabbit gastric glands was the first suitable method to be used and a number of important scientific contributions have been accomplished with this method. LÄS MER

  3. 33. The role of angiomotin in endothelial cell motility and cell-cell junction formation

    Författare :Anders Bratt; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Angiogenesis; cancer; angiostatin; angiomotin; cell motility cell-cell junction; tight junction; adherens junction;

    Sammanfattning : Clinical as well as pre-clinical data show that tumor growth can be restrained by inhibiting angiogenesis. We have been investigating the mechanism of action of angiostatin, an inhibitor of angiogenesis, in order to design novel therapies against cancer. LÄS MER

  4. 34. A Study On Factor Influencing the Microstructure and Shrinkage Porosity Formation in Compacted Graphite Iron

    Författare :Sadaf Vazehrad; Pär Jönsson; Attila Dioszegi; Steve Dawson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CGI; LGI; SGI; Solidification; Microstructure; Shrinkage porosity; Eutectic colony; Microsegregation;

    Sammanfattning : During the last decades, an intensive effort has been dedicated to introduce compacted graphite iron (CGI) for truck engine components as its intermediate graphite morphology provides an increased tensile property compared to lamellar cast iron (LGI) and a better thermal conductivity compared to nodular cast iron (SGI). However, the narrow production technology window in this cast iron grade requires increased technological discipline. LÄS MER

  5. 35. Experimental Studies of Deformation Structures in Stainless Steels using EBSD

    Författare :Karin Yvell; Annika Borgenstam; Peter Hedström; Göran Engberg; Johan Moverare; Högskolan Dalarna; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EBSD; Austenitic stainless steels; Duplex stainless steel; In situ tensile test; Grain boundaries; Grain rotation; Grain size distribution; Texture; Strain hardening; Structure-property relationship; High strain rate; Wire rod rolling; Roll forming; Steel Forming and Surface Engineering; Stålformning och ytteknik;

    Sammanfattning : In this thesis, the focus has been the study of deformation structures in stainless steels by using electron backscatter diffraction (EBSD). Via increased knowledge of the evolution of the substructure during deformation, the design and control of the manufacturing process can be improved. LÄS MER
