  2. 1. Modulating magnetic interactions : in metamaterials and amorphous alloys

    Author : Nanny Strandqvist; Björgvin Hjörvarsson; Alexei Vorobiev; Sean Langridge; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Magnetic metamaterials; interlayer exchange coupling; superlattice; mesospins; magnetic nanostructures; emergence; amorphous alloys; CoAlZr; FeZr; Fysik; Physics;

    Abstract : This thesis is focused on exploring and modulating magnetic interactions in metamaterials and amorphous alloys along one-, two-, and three-dimensions. First, thin films of alternating Fe and MgO are adapted to modulate magnetic interactions along one dimension. READ MORE

  4. 2. Cryptic Female Choice and Male Mating Behaviour : Sexual Interactions in Beetles

    Author : Martin Edvardsson; Göran Arnqvist; Paul Ward; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Cryptic female choice; Copulatory courtship; Harmful male traits; Nuptial gifts; Sperm competition; Sexual selection; Tribolium castaneum; Callosobruchus maculatus; Biologi; Biology; Biologi;

    Abstract : The importance of cryptic female choice, i.e. female post-copulatory influence over male reproductive success, in driving the evolution of male traits remains controversial. The main aim of this thesis was to understand the post-copulatory consequences of sexual interactions and the importance of cryptic female choice in two species of beetle. READ MORE

  5. 3. Microfluidic Cell and Particle Sorting using Deterministic Lateral Displacement

    Author : Stefan Holm; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microfluidics; Separation science; Deterministic Lateral Displacement; Cell analysis; Deterministic lateral displacement; Microfluidics; Particle sorting; Droplet microfluidics; trypanosomiasis; red blood cell; Cell sorting; Fysicumarkivet A:2018:Holm;

    Abstract : Microfluidics is a field which has the potential to revolutionize medical diagnostics. The ability to sort and analyse cells by the use of portable handheld devices has the potential to enable sensitive devices for point-of-care diagnostics. READ MORE

  6. 4. Dynamic interactions of interfacial polymers

    Author : Mark Plunkett; KTH; []
    Keywords : surface chemistry dynamic polymer interactions QCM AFM MASIF surface forces adhesion friction;

    Abstract : The relationship between the amount and conformation of apolymer at the solid-liquid interface, and the resultinginteraction forces between two such surfaces has beeninvestigated. With a degree of control of the polymerconformation, by varying the temperature, solvent quality,polymer charge density etc, it has been possible to measure andinterpret the resulting changes in the surface interactions.

  7. 5. Nanotribology, Surface Interactions and Characterization : An AFM Study

    Author : Rubén Álvarez-Asencio; Mark W. Rutland; Suzanne Giasson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemi; Chemistry;

    Abstract : When two surfaces achieve contact, then contact phenomena such as adhesion, friction and wear can occur, which are of great interest in many disciplines, including physics, physical chemistry, material chemistry, and life and health sciences. These phenomena are largely determined by the nature and magnitude of the surface forces such as van der Waals, capillary and hydration forces. READ MORE
