  2. 11. Development of an Anisotropic Finite Element Head Model for Traumatic Brain Injury Prediction

    Author : Chiara Giordano; Svein Kleiven; Songbai Ji; KTH; []
    Keywords : Axonal Strain; Brain Anisotropy; Traumatic Brain Injury; Finite Element Analysis; Brain Tissue; Constitutive Modeling.; Medical Technology; Medicinsk teknologi;

    Abstract : Traumatic brain injury (TBI) is a worldwide health care problem with very high associatedmorbidity and mortality rates. In particular, the diagnosis of TBI is challenging: symptomsoverlap with other pathologies and the injury is typically not visible with conventionalneuroimaging techniques. READ MORE

  4. 12. Multiscale interfacial engineering of heterogeneous electrocatalysts : From structural design to mechanistic study

    Author : Shiqi Zhou; Jiayin Yuan; Martin Oschatz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; heterogeneous electrocatalysis; electronic structure; coordination environment; single-atom catalysts; strain effect; hydrogen evolution reaction kinetics; charge transfer; electrochemical CO^2 reduction; local enrichment; materialkemi; Materials Chemistry;

    Abstract : In a typical heterogeneous electrocatalytic reaction, for the given active sites, the electronic structure plays a determining role in electron transfer between the active sites and reactant molecules, which impacts the reaction efficiency. Besides the electronic properties of the electrocatalysts, the reaction interface at which the charge transfer occurs plays an important role in the reaction kinetics. READ MORE

  5. 13. Topology optimization of non-linear, dissipative structures and materials

    Author : Niklas Ivarsson; Hållfasthetslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Topology optimization; Stiffness optimization; Finite strain; Rate-dependent plasticity; Discrete adjoint sensitivity analysis;

    Abstract : Topology optimization is a mathematical tool for finding optimal distributions of material phases within a design domain. It is commonly used in early design stages to generate conceptual structural layouts. Ultimately, designs generated by topology optimization consist of distinct material phases with enhanced performance. READ MORE

  6. 14. Enhancing membrane and secretory protein production yields in Escherichia coli

    Author : Zhe Zhang; Jan-Willem de Gier; Claes von Wachenfeldt; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; recombinant protein production; Escherichia coli; membrane protein; secretory protein; strain engineering; Biochemistry; biokemi;

    Abstract : Proteins fulfill essential functions in living cells. To produce sufficient amounts of a protein is essential to study the structure and function of a protein, or to use it for medical purposes. Escherichia coli is a Gram-negative bacterium that is widely used for recombinant protein production. READ MORE

  7. 15. Experimental characterization and numerical modeling of compression perpendicular to the grain in wood and cross-laminated timber

    Author : Shaheda T. Akter; Thomas K. Bader; Erik Serrano; Jan Oscarsson; Reinhard Brandner; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rolling shear; biaxial testing; stress combination; RT-plane; moisture influence; rolling shear creep; digital image correlation; strain field; CLT connection; rotational stiffness; rullskjuvning; biaxiell undersökning; spänningskombination; RT-plan; fuktpåverkan; krypning vid rullskjuving; digital bildkorrelation; töjningsfält; KLTanslutning; rotationsstyvhet; Byggteknik; Civil engineering;

    Abstract : Compression perpendicular to the grain (CPG) of wood is a typical loading situation in timber structures. It has been an extensively studied research topic for decades, due to the highly ductile behavior of wood under such loading, the large variations in mechanical properties, and the relevance of these properties in structural design.
