Electron diffraction is not only one of the most rapidly evolving fields in chemistry and crystallography, but it is also here to stay, as research proves that the novel analytical technique can produce impressive results.

Electron diffraction has the potential to revolutionize crystallographic research. Dr. Mauro Gemmi – Head of Center of Nanotechnology Innovation@NEST, Professor at Istituto Italiano di Tecnologia and the speaker for our scientific webinar on ED strongly believes so. Watch the recording to find out more about this novel technique.
Given the heightened interest in the last couple of years for electron diffraction and the increased nano-analytical capabilities associated with it, we would need to address some questions about its importance. We at ELDICO strongly advocate not only for this technique, but also for a dedicated instrument, tailored specifically for electron diffraction.
What is the main advantage of electron diffraction for scientists? Being able to solve structures from a single nano-crystal. This is one of the many topics covered by Dr. Tim Grüne – Head of Centre for X-Ray Structure Analysis, Faculty of Chemistry at University of Vienna in the kick-off webinar of ELDICO. We are offering you the recorded session of this great discussion.
As part of our efforts to demonstrate the power of ED, we carried out experiments on [2H]-3-amino-1,2,3 triazole (3-AT, C2N4H4). It is a challenge to distinguish C from N atoms. If we solve the structure from ED data, using same parameters as for X-ray data, the first solution results in a structure in which five out of six atom types are correctly assigned.
What about beam sensitive samples? Our team carried out a comparative experiment of alpha-Glycine with two different 3D ED methodologies: precession and continuous rotation, arriving at a surprising conclusion. Given that alpha-Glycine is a small and very simple aliphatic molecule and as such very sensitive to the electron beam, it is well suited to assess the importance of the data acquisition method.
