TEM and STEM alignment

The webpage of Prof. John Rodenburg (www.rodenburg.org) contains a series of tutorials on TEM and STEM alignment. It is very useful because it is not easy to find anywhere else concise and good information about the fundamentals of alignment of an electron microscope. When I started learning about electron microscopes, the procedure of their alignment was a complete Read More …

Two essential books to start writing your programs using Matlab

I post here the references of two very good books that are strongly recommended if you ever intend to write programs for processing your images or you data using Matlab, and to have them as tools that you can use and share by developping interactive programs with windows and buttons…. P Marchand and OT Holland. Graphics and GUIs Read More …

Transmission electron microscopy software at ULM

The image shows the webpage of the group of Prof. Christoph T. Koch at Ulm University which contains useful  transmission electron microscopy software. The  Electron and Ion Microscopy (ELIM) group focuses on the development of new techniques in quantitative transmission electron microscopy and scanning transmission electron microscopy.  This includes mostly the development of new and efficient Read More …

Nanomanipulation of atoms and nanostructures

Nanomanipulation is a hot topic and technology allows nowadays to manipulate smallest nanostructures or even atoms. Manipulation is a human task (apes too) that requires the use of the hands. But shrinking fo technologies are demanding tools that permit the manipulation at smaller and smaller scales. This goal requires a combination of several technologies that Read More …

In-situ HRTEM: gold atoms on carbon graphite

In-situ high-resolution TEM (HRTEM) is nowadays becoming routine with the development of electron microscopes with aberration correctors. Recently I published a paper about the atomic reconfigurations of Au nanoparticles capped with thiols under the electron beam. I was able to record some videos in-situ (by stacking images acquired in succesive time lapses) that I show next.

Ernst Ruska – Nobel Lecture

  The Nobel Prize in Physics 1986 was divided, one half awarded to Ernst Ruska “for his fundamental work in electron optics, and for the design of the first electron microscope”, the other half jointly to Gerd Binnig and Heinrich Rohrer “for their design of the scanning tunneling microscope”. “The Nobel Prize in Physics 1986“.

Peter W. Hawkes: a personal retrospective

Lately I am very interested in the history of electron microscopes, and I hope that some day an historian or a journalist or a scientist with a good sense of wording will write a book about this topic!. In the meantime the article below and the references cited herein are highly recommended. I found in my archives Read More …
