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

    Författare :Lukasz Michalak; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; master equation; magnetic nanoparticles; spin accumulation; molecular magnets; TMR; tunneling magnetoresistance; F-SET; ferromagnetic single-electron transistor; single-electron tunneling; nanomagnetism; spintronics; Coulomb blockade;

    Sammanfattning : 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. LÄS MER

  3. 2. Demonstrating reliableinstrumentation in theATLAS Tile Calorimeter : Fault tolerance and redundancy in hardware and firmwarefor the Phase-II Demonstrator project in preparation forHigh Luminosity LHC at CERN

    Författare :Henrik Åkerstedt; Samuel B. Silverstein; Jón E. Gudmundsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; CERN; ATLAS; Tile calorimeter; TileCal; FPGA; SEU; TMR; Kintex; Demonstrator; DaughterBoard; Radiation testing; Radiation tolerant; Physics; fysik;

    Sammanfattning : The Large Hadron Collider at CERN is scheduled to undergo upgrades in 2026-2028 to significantly increase its luminosity. These upgrades, while providing the experiments with a higher collision rate, pose a number of challenges to the design of the hardware and software in the detectors. LÄS MER

  4. 3. Ley crop silage in diets to fattening pigs : How does it affect pig performance, nitrogen utilization, health and behaviour?

    Författare :Johanna Friman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : There is an increasing interest to use silage as a feed ingredient to pigs. The aim of this thesis was to study the effect of using silage in the diet to fattening pigs and how feeding strategy influenced pig performance, behaviour, gut health and nitrogen utilization. Two studies were performed. LÄS MER

  5. 4. Single molecule dynamics

    Författare :Lars Edman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Properties found in an ensemble of molecules may not be understood if it is not possible to study each molecule one by one. This thesis is concerned with the study of the dynamic properties of individual complex biological molecules as observed by confocal single-molecule fluorescence spectroscopy. LÄS MER

  7. 5. Detecting the dynamics of single biomolecules

    Författare :Stefan Wennmalm; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This thesis is concerned with the detection of single biomolecules. Through detection of individual molecules it can be clarified whether a behavior which has been observed in a population is representative for all molecules. For detection confocal fluorescence microscopy was used, in particular Fluorescence Correlation Spectroscopy (FCS). LÄS MER
