  1. 1. Self-assembly of magnetic particles

    Författare :Hauke Carstensen; Max Wolff; Vassilios Kapaklis; Björgvin Hjörvarsson; Benjamin Yellen; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; self-assembly; tunable interactions; phase transition; ferrofluid; Fysik; Physics;

    Sammanfattning : Self-assembly is the spontaneous formation of larger structures from small building blocks. This process is driven and determined by the interactions between the constituents. LÄS MER

  2. 2. Magnetically governed self-assembly of soft matter : A look into interfacial layering, crystallization and percolation

    Författare :Apurve Saini; Max Wolff; Vassilios Kapaklis; Pietro Tierno; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Self-assembly; Soft matter; Colloids; Magnetic nanoparticles; Ferrofluid; Solid-liquid interface; Neutron reflectometry; Electrical sensing; Microcontact; Materiefysik; Physics of Matter;

    Sammanfattning : Self-organisation is the key route for assembling colloidal particles into well-defined structures. Decisive for this are the interactions between the constituents, which are amongst others steric, electrostatic or magnetic. LÄS MER

  3. 3. Molecular Diagnostics Using Volume-Amplified Magnetic Nanobeads : Towards the Development of a Novel Biosensor System

    Författare :Mattias Strömberg; Maria Strømme; Peter Svedlindh; Mikkel Fougt Hansen; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Magnetic Biosensors; Ferrofluid; Biofunctionalisation; Ferrofluidic Aging; Interbead Interactions; Magnetic Nanobeads; Complex Magnetisation; Brownian Relaxation; Padlock Probes; Rolling Circle Amplification; Engineering physics; Teknisk fysik;

    Sammanfattning : Micro- or nanometer sized magnetic particles (beads) currently have a vast range of life science applications in, for example, bioseparation techniques, cancer therapy, development of contrast agents and biosensing techniques. In the latter field, magnetic beads offer several unique advantages, including minimal background signals, physical and chemical stability and low manufacturing costs. LÄS MER

  4. 4. On steady waves in two-layer fluids and ferrofluids

    Författare :Dag Nilsson; Partiella differentialekvationer; []
    Nyckelord :Internal waves; ferrofluids; partial differential equation; nonlinear waves; travelling waves; solitary waves; dynamical systems; Hamiltonian systems; non-local equations;

    Sammanfattning : This thesis concerns travelling waves in a two-layer fluid and on a ferrofluid jet. We prove existence of several types of such waves by reformulating the corresponding governing equation as an infinite dimensional dynamical system, where an unbounded spatial coordinate is used as time.

  5. 5. Collective behavior of disordered magnetic systems

    Författare :Tomas Jonsson; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Sammanfattning : Magnetic properties of disordered and frustrated magnets have been experimentally investigated. The magnetic systems in focus in this work are spin-glasses and frozen ferrofluids (suspensions of nano-sized magnetic particles). LÄS MER
