  2. 11. Fluorescence Properties of Quantum Dots and Their Utilization in Bioimaging

    Author : Hao Xu; Ying Fu; Hjalmar Brismar; Marina Zelenina; Mattias Goksör; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fluorescence; Microscopy; Bioimaging; Nanomaterial; cytotoxicity; mechanism; Biological Physics; Biologisk fysik;

    Abstract : Quantum dots (QDs), especially colloidal semiconductor QDs, possess properties including high quantum yields, narrow fluorescence spectra, broad absorption and excellent photostability, making them extremely powerful in bioimaging. In this thesis, we studied the fluorescence properties of QDs and attempted multiple ways to boost applications of QDs in bioimaging field. READ MORE

  4. 12. Development of large-scale molecular and nanomaterial models

    Author : Mikhail Ivanov; Alexander P. Lyubartsev; Arnold Maliniak; Herre Jelger Risselada; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular simulations; Coarse-grained models; Lipids; TiO2 surface; Machine learning; Physical Chemistry; fysikalisk kemi;

    Abstract : Molecular simulations can access unique atomic-scale information about new materials, pharmaceuticals, and biological environments, making cost-effective predictions and aiding experimental studies. They are particularly useful for describing the mechanisms of nanoscale phenomena and the biological/inorganic interfaces. READ MORE

  5. 13. Carbon nanomaterial-based interconnects, integrated capacitors and supercapacitors

    Author : Muhammad Amin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon nanotubes; Integrated capacitors; vertically aligned carbon nanofibers; Interconnects; PECVD; Interdigitated micro-supercapacitors;

    Abstract : The constant miniaturization and steady performance improvement of electronics devices have generated innovative ideas such as internet of thing (IoT), which also includes devices with integrated energy sources. The high performance is conceived by the high density of the devices on a chip leading to a high density of interconnects, to connect these devices to outside world. READ MORE
