  1. 1. InP-based photonic crystals Processing, Material properties and Dispersion effects

    University dissertation from Stockholm : KTH

    Author : Audrey Berrier; Srinivasan Anand; Alfred Forchel; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Photonic crystals; indium phosphide; photonic bandgap; Bloch modes; slow light; dispersion; coupled cavity waveguides; chemically assisted ion beam etching; lag effect; cavities; optical losses; carrier transport; carrier lifetimes; negative refraction; photonic bandstructure; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Abstract : Photonic crystals (PhCs) are periodic dielectric structures that exhibit a photonic bandgap, i.e., a range of wavelength for which light propagation is forbidden. The special band structure related dispersion properties offer a realm of novel functionalities and interesting physical phenomena. READ MORE

  2. 2. Single-Electron Tunneling Spectroscopy in Magnetic Nanoparticles and Molecular Magnets

    University dissertation from Division of Solid State Physics, Lund Institute of Technology, Lund University

    Author : Lukasz Michalak; [2010-12-13]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; master equation; magnetic nanoparticles; spin accumulation; molecular magnets; TMR; tunneling magnetoresistance; F-SET; ferromagnetic single-electron transistor; single-electron tunneling; nanomagnetism; spintronics; Coulomb blockade;

    Abstract : This thesis deals with single-electron tunneling in transistor-like devices in which the central electrode is either a metal nanoparticle (possibly ferromagnetic) or a molecular magnet. The investigated systems split into two different categories, depending on the size of the central island. READ MORE

  3. 3. Controlling virulence in Yersinia pseudotuberculosis through accumulation of phosphorylated CpxR

    University dissertation from Umeå : Umeå university

    Author : Edvin Thanikkal; Matthew Francis; Andrew Darwin; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Y. pseudotuberculosis; CpxA; CpxR; invasin; RovA; RovM; T3SS; virulence; transcriptional regulation; molekylärbiologi; Molecular Biology; mikrobiologi; Microbiology;

    Abstract : Like many Gram-negative bacteria, the food-borne pathogen Yersinia pseudotuberculosis harbours different regulatory mechanisms to maintain an intact bacterial envelope especially during exposure to extracytoplasmic stress (ECS). The CpxA-CpxR two component regulatory system is one such ECS-responsive regulatory mechanism. READ MORE

  4. 4. Properties and analysis of dioxin-like compounds in marine samples from Sweden

    Abstract : Polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs), and dioxin-like polychlorinated biphenyls (PCBs) have been assigned toxic equivalency factors (TEFs). These compounds are today routinely analysed with sophisticated analytical techniques. READ MORE

  5. 5. Micromechanics approach to stiffness characterization of woven composites

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Normunds Jekabsons; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera konstruktionsmaterial;

    Abstract : Thesis consider the stiffness of woven composites, methods of its calculation and stiffness reduction due to damage accumulation during the service. First, reliable methods for stiffness calculation of undamaged woven composites are considered. There are a large amount of simple approximate methods available in literature. READ MORE
