Description

In a first part, I will briefly survey how a magnetic field can be used in order to focus an electron beam and then how a transmission electron microscope works. Recent experimental developments such as the correction of the spherical aberration of electron lenses and the resulting atomic resolution will be showed. I will then present how this techniques are now widely used in the order to solve various problematics such as the imaging of nanostructures (from the industrial oriented characterisation of multilayers to the imaging of nanoparticles into organic matter) or the structural refinement of crystalline or defective systems (such as bonding at interfaces or the topological description of defects in functionalised nanotubes). Finally I will discuss how combining electron spectroscopy and microscopy, physical or chemical properties such as the oxidation state of transition metal oxide nanoparticles or the plasmonic properties of metallic clusters can be investigated.

The video is working fine, maybe the issue is in your connection? Downloads will be available in a few months i hope...

Thanks, looking forward for downloading this nice presentation


Comment4 Dr S Ganguly, March 4, 2010 at 9:32 a.m.:

Thank you very much. If possible please provide the link for download.


Comment5 N R K murthy, September 27, 2010 at 8:49 p.m.:

when will you give download option


Comment6 george, October 21, 2010 at 1:05 a.m.:

why the camera was spoted on the bar head of the profes. during the discution instead of to show us the slide whitch speaking about it make us out of phase to understand the lecture

IT is a very instructive talk about electron microscopy and spectroscopy. I will recommend it to every researcher who is using TEM for his research.
Thanks very much!
