  1. 1. Collective properties of magnetic mesospins

    Författare :Erik Östman; Björgvin Hjörvarsson; Vassilios Kapaklis; Nicolas Rougemaille; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; artificial spin ice; magnetic nano-structures; mesoscopic spin systems; mesospins; mixed spin dimensionalities; interaction modifier; engineering of energy landscape; emergence;

    Sammanfattning : Mesoscopic spin systems consist of an ensemble of lithographically patterned nanomagnetic elements - mesospins. The interactions between the mesospins, can be designed at will by altering their lateral arrangement, enabling the study of collective magnetic order in a wide range of systems. LÄS MER

  3. 2. Generic Properties of Polymer Solutions

    Författare :Takashi Uematsu; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photon correlation spectroscopy; collective diffusion; atomic force microscopy; relaxation; agarose gel electrophoresis; DNA; Zimm dynamics; pulsed-field gradient NMR; superdiffusion; polymer solution; blob model; gel;

    Sammanfattning : Polymer solutions are abundantly present in our daily life, for example in paints, jellies, contact lenses and even in the living cells. Despite their ubiquity, we still have a poor understanding of the physical properties of solutions due to the extremely large number of internal degrees of freedom. LÄS MER

  4. 3. Analyzing and realizing collective ideation in firms

    Författare :Jennie Björk; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ideation performance; collective ideation; ideas; social network analysis; innovation; networks; Ideation; social networks;

    Sammanfattning : Analyzing and realizing collective ideation in firmsJennie BjörkDepartment of Technology Management and EconomicsChalmers University of TechnologyAbstractThis thesis investigates collective aspects of ideation. An increasing body of literature has moved away from regarding ideation as solely the act of single individuals to acknowledge the importance of inter-individual relationships. LÄS MER

  5. 4. Particle interactions at the nanoscale : From colloidal processing to self-assembled arrays

    Författare :Bertrand Faure; Lennart Bergström; Albert Philipse; Stockholms universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Colloidal processing; nanoparticles; colloidal forces; titania; iron oxide; Hamaker constant; surface modification; rheology; Monte Carlo simulations; collective properties; superparamagnetism; finite-size effects; Materials Chemistry; materialkemi;

    Sammanfattning : Nanostructured materials are the next generation of high-performance materials, harnessing the novel properties of their nanosized constituents. The controlled assembly of nanosized particles and the design of the optimal nanostructure require a detailed understanding of particle interactions and robust methods to tune them. LÄS MER

  7. 5. Theoretical description of Ti and Ti alloys from first principles

    Författare :Natalia Skripnyak; Igor Abrikosov; Iryna Yakimenko; Sergey Simak; Zi-Kui Liu; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; T; Ti alloys; DFT; molecular dynamics; thermodynamic properties; elastic properties;

    Sammanfattning : Modern world is known for many advanced technologies and solutions to complex problems. Technical progress runs at high speed. In order to most effectively use materials, given to us by Nature, it is important to know their properties. To do laboratory experiments is often too expensive and time consuming. LÄS MER
