Prof. Giuseppe Battaglia and his group at University College in London have performed high resolution imaging of Ferritin proteins in liquid using a DENSsolutions Ocean In situ liquid system and a Gatan K2-IS. We are looking at objects as small as 10 nm imaged at a resolution close to 1 nm. These preliminary results highlight once more the importance of Liquid Phase Electron Microscopy (LP EM) and the need for a stable and reliable liquid cell solution
Researchers at Zhejiang University, using a DENSsolutions Climate S3+, have performed an atomic scale TEM observation of shape evolution of Pd nanocrystals under oxygen and hydrogen environments at atmospheric pressure. By combining imaging with multi-scale structure reconstruction model calculations, they have been able to fully understand the reshaping mechanism. The work has deserved the back cover page of the Chemical Communications journal.
On the way towards more accurate understanding of the dynamics under gas atmosphere, Ernst Ruska-Center for Microscopy and Spectroscopy with Electrons has launched a Master Student Project that will deal with the challenges of beam effects on catalyst nanoparticles under gas environment. More specifically, in this project a systematic study on the effect of electron dose on the DENSsolutions Climate Nano-Reactor will be carried out as well as on the catalyst nanoparticles, with the aim of determining the optimum dose level in the trade-off between damage and signal. Characterizing the effect of the electron beam will result in a greater understanding of in-situ experiments in the electron microscope in order to bridge the ‘pressure-gap’. Towards the end of the project the optimized dose will be used to look at Pt/carbon catalysts for hydrogen fuel-cell applications.

In-situ electron energy loss spectroscopy (EELS) is of immense value when studying the chemical structure of functional materials at the atomic scale1. This webinar will introduce the types of information you can obtain using in-situ EELS. Practical examples will be shown by reviewing published in-situ EELS work as well as unpublished in-situ EELS videos obtained using the GIF Quantum® K2 IS system from Gatan.
In the second part of this webinar, we will look more closely at the accuracy of the in-situ heating that is required for each of the experiments presented. MEMS-based heating will be specifically discussed since these holders are now widely used to improve stability at elevated temperatures. We will discuss the technology behind DENSsolutions heating solutions as well as methods, including one EELS-based technique, used to confirm the temperature accuracy of the sample.
Last Thursday, the results of the Dutch Deloitte Fast 50 have been announced at the official ceremony in Utrecht . We have been awarded the 1st place in the “hardware” section and 22nd overall. The final ranking is available here
It’s simply an amazing achievement that rewards our work and dedication in the field of in situ electron microscopy; the award gives a further boost to our commitment of moving the frontiers of in situ EM further and further in the next years.
From the entire DENSsolutions team, a big thanks to our customers, distributors and suppliers for making it possible.
Are you ready for a game changer in the MEMS heating arena? We are glad to inform you that we will be launching our new heating Nano-Chip very soon.
