    Sammanfattning : The CIS solar cell family features both a high stability and world-class performances. They can be deposited on a wide variety of substrates and absorb the entire solar spectrum only using a thickness of a few micrometers. LÄS MER

  4. 23. Taming of Oxygen in the Electron Microscope : Effects of High Energy Electron Irradiation on O2 and Oxides

    Författare :David Wahlqvist; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transmission electron microscope; Environmental transmission electron mircoscopy; Electron Beam damage; Oxidation; carbon black;

    Sammanfattning : Transmission electron microscopy (TEM) is an atomic resolution technique that allows for in depth analysis of the properties of different materials by passing high energy electrons through a thin sample and detecting how they are affected. However, due to the strong interaction between electrons and matter, the probability of the sample remaining unperturbed by the electron irradiation is small. LÄS MER

  5. 24. Development of electron microscopy towards nano-structured porous materials : Focus on novel zeolites from layered silicates and chiral mesoporous nanotubes

    Författare :Juanfang Ruan; Osamu Terasaki; James C. Vartuli; Stockholms universitet; []
    Nyckelord :Transmission electron microscopy; Layered silicates; Chiral mesoporous nanotubes; strukturkemi; Structural Chemistry;

    Sammanfattning : Three novel zeolites (M-IEZ-MWW, IEZ-FER and IEZ-CDO) have been successfully synthesised from the corresponding precursors. Structure characterisation of those materials was conducted by TEM. LÄS MER

  7. 25. Nanoscale Osseointegration : Characterization of Biomaterials and their Interfaces with Electron Tomography

    Författare :Kathryn Grandfield; Håkan Engqvist; Peter Thomsen; Anders Palmquist; Alexandra Porter; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electron tomography; transmission electron microscopy; hydroxyapatite; titanium; titania; bone; implant; osseointegration; interface; mesoporous; Materialvetenskap; Materials Science;

    Sammanfattning : Bone response is one of the key determining factors in the overall success of biomaterials intended for bone regeneration and osseointegration. Understanding the formation of bone at an implant surface may lead to the improved design of biomaterials for the future. LÄS MER
