  1. 1. A Fast Pixelated Thermal-Neutron Detector

    Author : Emil Rofors; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SoNDe; thermal-neutron detector; GS20 scintillator; Li-glass; H12700A MAPMT; position-dependent response; alpha-particle; proton; deuteron; neutron; ESS; SKADI;

    Abstract : This thesis presents the study of a position-sensitive scintillation-based detector called the Solid-State Neutron Detector (SoNDe). SoNDe is being developed for cold- and thermal-neutron detection at the small-angle neutron scattering (SANS) instrument SKADI at the European Spallation Source (ESS), currently under construction in Lund, Sweden.

  2. 2. High Resolution Tip-Enhanced Raman Images of Single Molecules from First Principles Simulations

    Author : Zhen Xie; Yi Luo; Filippo De Angelis; KTH; []
    Keywords : First Principles; Tip-Enhanced Raman Images; light-matter interactions at the nanoscale; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Abstract : With the precise control of spatially confined plasmon (SCP), tip-enhanced Raman spectroscopy (TERS) has achieved sub-nanometer resolution, leading to the chemical and physical characterization of the single molecule by optical Raman images. In the high resolution TERS measurements, the SCP spatial distribution generates the position-dependent Raman images. READ MORE

  3. 3. III-V Nanowire Array Solar Cells: Optical and Electrical Modelling

    Author : Yang Chen; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Semiconductor solar cell; nanowire array; modelling; Fysicumarkivet A:2018:Chen;

    Abstract : This thesis describes optical and electrical modelling of vertically oriented III-V semiconductor nanowire array solar cells (NWASCs).In the optical studies, three-dimensional electromagnetic modelling was carried out with the scattering matrix method and the finite element method.

  4. 4. Enhancing Direct Searches for Dark Matter : Spatial-Temporal Modeling and Explicit Likelihoods

    Author : Bart Eduard Jan Pelssers; Jan Conrad; Jochen Schieck; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dark matter; direct detection; statistical analysis; fysik; Physics;

    Abstract : Astronomical and cosmological observations on different scales point to the existence of dark matter. In the current cosmological paradigm this dark matter accounts for about 26% of the energy-density of the universe, yet has not been directly observed. READ MORE

  5. 5. Neural control of standing posture

    Author : Craig Tokuno; Andrew Cresswell; Alf Thorstensson; Marc Carpenter; Thomas Sinkjær; Gymnastik- och idrottshögskolan; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Medicin Teknik; Medicine Technology; Posture; motor cortex; electromyography; kinematics; H-reflex; pre-synaptic inhibition; transcranial magnetic stimulation;

    Abstract : When humans are asked to stand normally, they are not completely motionless. Rather, small amounts of body movement, termed postural sway, can be observed. Although the postural sway of standing has been well described, the manner in which this sway is neurally controlled and its influence in tasks involving postural re-stabilization are not known.
