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

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

    Sammanfattning : 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. LÄS MER

  3. 2. Protons, other Light Ions, and 60Co Photons : Study of Energy Deposit Clustering via Track Structure Simulations

    Författare :Gloria Bäckström; Anders Ahnesjö; Nina Tilly; José M. Fernández-Varea; Niels Bassler; Uppsala universitet; []
    Nyckelord :Proton; light ion; Co-60 photon; track structure Monte Carlo code; clustering patterns of energy deposit; RBE; Medicinsk radiofysik; Medical Radiophysics;

    Sammanfattning : Radiotherapy aims to sterilize cancer cells through ionization induced damages to their DNA whilst trying to reduce dose burdens to healthy tissues. This can be achieved to a certain extent by optimizing the choice of radiation to treat the patient, i.e. the types of particles and their energy based on their specific interaction patterns.

  4. 3. Characterization of Process-related Defects in Silicon Carbide by Electron Microscopy

    Författare :Per O. Å. Persson; Pirouz Pirouz; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Silicon carbide (SiC) is a semiconducting material, which provides advantages compared to other available semiconducting materials. Attractive properties of SiC are the wide bandgap (2.2-3.3 eV), high electric breakdown field (3x106 Vcm-1), high thermal conductivity (5 Wcm-1 K-1) and the chemical stabi!ity. LÄS MER

  5. 4. Development of Organic-Based Thin Film Magnets for Spintronics

    Författare :Elin Carlegrim; Mats Fahlman; Ronald Österbacka; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : In the growing field of spintronics, development of semiconducting magnets is a high priority. Organic-based molecular magnets are attractive candidates since their properties can be tailor-made by organic chemistry. Other advantages include low weight and low temperature processing. LÄS MER

  7. 5. Preparation of Functional Oxide Perovskites: A Study on the Growth-Microstructure-Property Relationships of(N a,K)NbOx Thin Films

    Författare :Veronika Mozhdeh Kugler; S. Ismat Shah; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Sodium-potassium niobate is a material with ferroelectric and piezoelectric properties that has been known since 1954. Recently, perovskite structured ferroelectric thin films have gained a lot of attention due to their wide area of potential applications, including non-volatile memories, infrared sensors, optical switches, and ultrasonic transducers.
