  1. 1. Surface characterization of 2D transition metal carbides (MXenes)

    Författare :Ingemar Persson; Per Persson; Justinas Palisaitis; Johanna Rosén; Vanya Darakchieva; Vincent Mauchamp; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Research on two-dimensional (2D) materials is a rapidly growing field owing to the wide range of new interesting properties found in 2D structures that are vastly different from their three-dimensional (3D) analogues. In addition, 2D materials embodies a significant surface area that facilitates a high degree of surface reactions per unit volume or mass, that is imperative in many applications such as catalysis, energy storage, energy conversion, filtration, and single molecule sensing.

  3. 2. The Influence of the Adenosine A1-receptor on Tubuloglomerular Feedback and Renin Release

    Författare :Russell Brown; A Erik G Persson; Pontus Persson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; adenosine; tubuloglomerular feedback; renin release; blood pressure; micropuncture; Fysiologi; Physiology; Fysiologi;

    Sammanfattning : The kidneys play a vital role in the maintenance of extracellular fluid and electrolyte balance and blood pressure. Adenosine, acting through the adenosine A1-receptor (A1R), and nitric oxide have been implicated in several of the regulatory mechanisms in the kidney. LÄS MER

  4. 3. Nanowires in Cell Biology

    Författare :Henrik Persson; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phase holographic microscopy; Nanowires; living cells; cell injection; Fysicumarkivet A:2014:Persson;

    Sammanfattning : This thesis explores the interactions between cells and nanowires, to increase our understanding of how cells are affected and how they can be manipulated by these one-dimensional, semiconductor crystals (lengths 1-10 µm, diameters .... LÄS MER

  5. 4. Optical Studies of Single Quantum Dots

    Författare :Jonas Persson; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nano-optics; quantum optics; photoluminescence; micro-photoluminescence; single photon generation; Semiconductory physics; Halvledarfysik; low-dimensional structures; quantum dots; Stranski-Krastanow; Fysicumarkivet A:2004:Persson;

    Sammanfattning : This thesis presents spectroscopic studies of single self-assembled InP quantum dots (QDs). The electronic properties of these QDs have been studied by photoluminescence (PL) and scanning tunnelling luminescence (STL). The QDs were grown in the Stranski-Krastanow mode and were embedded in GaInP. LÄS MER

  7. 5. Theoretical study of electronic structure and optical properties of semiconductor nanostructures

    Författare :Martin Persson; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanowire superlattices; nanostructures; band structure; wavefunctions; III-V materials; optical properties; Halvledarfysik; Semiconductory physics; Fysicumarkivet A:2004:Persson; Tight-binding theory; nanocrystals; nanowires;

    Sammanfattning : In this thesis, the electronic structure and optical properties of semiconductor nanostructures are studied theoretically. Three types of nanostructures have been studied, silicon nanocrystals, free-standing III-V nanowires and free-standing GaAs/AlGaAs nanowire superlattices. LÄS MER
