5. 9. Transmission Electron Microscopy of 2D Materials : Structure and Surface Properties

   Författare :Linda Karlsson; Per Persson; Javier Bareno; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transmission Electron Microscopy; Two-dimensional materials; Graphene; MXene; Ti3C2Tx; Low-voltage TEM; Aberration-corrected TEM; monchromated TEM; Scanning transmission electron microscopy; Electron energy loss spectroscopy;

   Sammanfattning : During recent years, new types of materials have been discovered with unique properties. One family of such materials are two-dimensional materials, which include graphene and MXene. These materials are stronger, more flexible, and have higher conductivity than other materials. As such they are highly interesting for new applications, e. LÄS MER

7. 10. A TEM Investigation of Contact between Nanoparticles

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

   Sammanfattning : 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. LÄS MER
