  4. 2. A TEM Investigation of Contact between Nanoparticles

    Author : Yiming Yao; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LACBED; CBED; nanoparticles; interface; adhesion; image simulation; energy filtering; misorientation; contacting; strain field TEM;

    Abstract : Interaction between nanoparticles (1~100nm) provides us with answers to fundamental questions in many important applications e.g. adhesion, friction, and cold welding. The attractive force arises from the reduction of the total free surface and thus the total surface energy due to the formation of a boundary between the contacting particles. READ MORE

  6. 4. Synthesis of carbon-covered iron nanoparticles by photolysis of ferrocene

    Author : Karine Elihn; Knut Deppert; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; iron; carbon; nanoparticle; ferrocene; laser-assisted CVD; particle size; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Abstract : One important driving force in nanotechnology today is the change which can be made in the properties of a material when the dimensions of its individual building blocks are decreased below approximately 100 nm. Such small building blocks, typically nanoparticles, may induce new and unique properties compared to those of the corresponding bulk material. READ MORE

  7. 5. Analysis of Structure, Composition and Growth of Semiconductor Nanowires by Transmission Electron Microscopy

    Author : Martin Ek; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transmission electron microscopy; nanowires; III-V semiconductors; polarity; in-situ TEM;

    Abstract : Nanowires have the potential to be a very flexible platform for the design of semiconductor devices. In nanowires it is possible to form crystal structures not found in the bulk materials under normal conditions, and to combine different III-V and group IV materials into axial or radial heterostructures.
