  2. 1. Ceramic Core–Shell Particles : Synthesis and Use within Dentistry

    Author : Camilla Berg; Wei Xia; Håkan Engqvist; Nicola Döbelin; Uppsala universitet; []
    Keywords : Calcium phosphate; Core-shell particles; Substituting ions; Dentin hypersensitivity; Occlusion; Mineralization; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : Dentin hypersensitivity is one of the most prevalent conditions related to oral health, affecting a large share of the adult population. Shortcomings with the available treatment options are related to non-ideal particle sizes and degradation properties. READ MORE

  4. 2. Ultrafast Photoinduced Processes in Core and Core–Shell Quantum Dots for Solar Cell Applications “Tiny Crystals for Big Applications”

    Author : Mohamed Qenawy; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum dots; core–shell; electron injection; hole injection; hole trapping; exciton migration; solar cells; ultrafast dynamics; time-resolved spectroscopy.;

    Abstract : The balance between our demands of energy and the energy we are consuming is not in equilibrium anymore. Therefore, the search for other energy resources is indispensable. Sustainable energy sources offer the alternative to the fossil fuels. READ MORE

  5. 3. Charge carrier dynamics in colloidal quantum dots: Tracking the dance of electrons and holes by ultrashort laser pulses

    Author : Nils Lenngren; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CdSe; quantum dots; ultrafast spectroscopy; charge carrier dynamics;

    Abstract : Quantum dots (QDs) are semiconductor nanocrystals with quantum confinement. This thesis uses various time-resolved spectroscopic techniques to study ultrafast charge carrier dynamics in colloidal CdSe quantum dots that are important both from a theoretical point of view and for their relevance for solar cell applications.
