  1. 6. VO2-based Thermochromic and Nanothermochromic Materials for Energy-Efficient Windows : Computational and Experimental Studies

    Författare :Shuyi Li; Claes-Göran Granqvist; Gunnar Niklasson; Ivan Parkin; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; VO2; thermochromism; nanothermochromics; energy efficient windows; optical modeling; effective medium theory; thin film characterization; doping;

    Sammanfattning : VO2-based films are thermochromic and exhibit high or low infrared transmittance when the temperature is below or above a critical temperature. The thermochromic switching is passive and reversible, and therefore VO2 based films are promising for energy-efficient window appli­cations. LÄS MER

  3. 7. Nanocellulose and Metal-Organic Framework-Based Composites : Synthesis, Characterization, and Applications

    Författare :Shengyang Zhou; Chao Xu; Maria Strömme; Lars Wågberg; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanocellulose; Metal–organic frameworks; Nanocomposites; Interfacial synthesis; Porous materials; Energy storage; Water purification;

    Sammanfattning : Nanocellulose is one of the most promising of the green materials available for use in a sustainable economy because of its natural abundance and renewability. Compared to petroleum‒derived synthetic polymers, nanocellulose has many unparalleled advantages such as its unique nanofibrous structure, high thermal stability, mechanical flexibility, rich surface chemistry, biocompatibility, and biodegradability.

  4. 8. Engineered core : shell nanoparticles: synthesis, characterisation, and biocompatibility studies

    Författare :Carmen Mihaela Vogt; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Superparamagnetic iron oxide nanoparticles (SPIONs) have emerged as promising contrast agents for Magnetic Resonance Imaging (MRI). Some SPIONs are already approved for clinical use. Coating of these nanoparticles with an additional biocompatible layer serves to improve the colloidal stability and biocompatibility. LÄS MER
