   Abstract : The discovery and subsequent synthesis of metal containing fullerenes- IFS (Inorganic Fullerene-like Structures) by R. Tenne et al. has generated considerable scientific interest with great potential impact in many industrial application areas such as lubrication. READ MORE

4. 2. Development and application of advanced electron microscopy techniques for materials in biological systems

   Author : Pernilla Nevsten; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; multiple-unit drug; EFTEM; EELS; cyanine dye; SSAT; cryo-TEM; virus; TEM; apoptosis; SEM; AFm; α-TCP; apatite; XEDS; TEM grid; microscopy supports;

   Abstract : Theoretically, electron microscopy and scanning probe microscopy offer information on a scale beyond the optical microscope. However, the quality of the micrograph and the obtained information is limited by the sample preparation. READ MORE

5. 3. Development of Cermet Microstructures during Sintering and Heat-Treatment

   Author : Jenni Zachrisson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; APFIM; EELS; cemented carbides; quantitative microanalysis; gradients; N ; TEM; EFTEM; hardmetals; EDX; Ti C; light elements;

   Abstract : The work presented in this thesis is concerned with the microstructure of Ti(C, N) based cermet materials used in cutting tool applications. Several techniques have been used to study the microstructure of cermets, in particular transmission electron micro-scopy in combi-na-tion with energy dispersive X-ray analysis and electron energy-loss spectroscopy, energy-filtered transmission electron micro-scopy, atom-probe field-ion microscopy and scanning electron microscopy.

6. 4. Towards atomically resolved magnetic measurements in the transmission electron microscope : A study of structure and magnetic moments in thin films

   Author : Hasan Ali; Klaus Leifer; Peter Van Aken; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Transmission electron microscope; thin films; magnetic moments; electron energy loss spectroscopy; simultaneous acquisition; electron magnetic circular dichroism; Teknisk fysik med inriktning mot materialanalys; Engineering Science with specialization in Materials Analysis;

   Abstract : The magnetic properties of thin metallic films are significantly different from the bulk properties due to the presence of interfaces. The properties shown by such thin films are influenced by the atomic level structure of the films and the interfaces. READ MORE

7. 5. Modeling Vibrational Electron Energy Loss Spectroscopy with the Frequency-Resolved Frozen Phonon Multislice Method

   Author : Paul Michel Zeiger; Jan Rusz; Rebecca Nicholls; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electron Energy Loss Spectroscopy; Phonons; Scanning Transmission Electron Microscopy; Frozen Phonon Multislice; Molecular Dynamics; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Abstract : Aberration correctors, improved monochromators, and better detectors have enabled exciting research with nanometer- and Ångstrom-scale resolution in the Scanning Transmission Electron Microscope (STEM). However the interaction of high-energy electrons with the many-body system of the sample is quite complex and hinders interpretation of experiments. READ MORE
