This time we showcase a very interesting paper that highlights once more the need for extremely stable imaging conditions when performing in situ heating. In this contribution, the authors have imaged octahedral faceted nanoparticles at different temperatures. These particles are highly attractive fuel cell catalysts as a result of their activity for the oxygen reduction reaction (ORR). However, their surface compositional and morphological stability currently limits their long-term performance in real membrane electrode assemblies (MEAs). Specifically, they authors have performed in situ heating of compositionally segregated PtNi1.5 octahedral nanoparticles inside a transmission electron microscope, in order to study their compositional and morphological changes.

“The authors clearly gave a lot of thought to the issues that could be of interest for a potential user during an in situ TEM experiment before starting the redesign of their system” and “I think it is very good that the company is actively engaging with the scientific community by sharing their views and information on the design of their products by submitting a paper to this journal.”
With these words from the reviewers, we are happy to announce that our own contribution to the scientific community, featuring all you need to know about our advanced heating chips, has been published on Ultramicroscopy.
You can download it for free until the 13th of July.

At DENSsolutions we are proud to sponsor the Irvine Materials Research Institute and the International Symposium on Advanced Electron Microscopy and Spectroscopy. The symposium will run from the 6th until the 8th of June.

If you are going to attend do not miss the chance to attend our presentation focused on the latest developments in the field of in situ EM.

“Irvine Materials Research Institute (IMRI) is a newly established interdisciplinary organization under the Office of Research of the University of California, Irvine (UCI). It serves as the cross-campus nexus for materials research at UCI. IMRI operates a wide range of state-of-the-art, open-access user facilities for the characterization of materials, biological samples, and devices from sub-Å to macroscopic length scales – available to all university, industry, and non-profit researchers. It offers advanced techniques and services supported with professional staff.

Following the completion of a major renovation and the establishment of a premier Transmission Electron Microscopy (TEM) facility, the IMRI is now open to serve all university, industry and nonprofit researchers. Poised to become one of the world’s preeminent centers of excellence for the interdisciplinary research, discovery and development of engineered and natural materials, systems and devices, IMRI is home to several of the highest performance Transmission Electron Microscopes (TEM) available in the world today. We are honored to invite you to join us at the grand opening and the International Symposium on Advanced Electron Microscopy and Spectroscopy (SAEMS) and share with you our accomplishments.

The two day symposium will bring together the scientific community working on various aspects of research and development in TEM to encourage the exchange of ideas for the advancement and challenges in atomic scale imaging and spectroscopy. There will be over 50 internationally renowned TEM experts and scientists participating in this event.”

DENSsolutions B.V. is pleased to announce a change in its distribution network. Effective 1st April 2018, we are covering the following territories directly: North America, Japan and India, previously covered by Gatan, Inc.

It is our intention to further consolidate and strengthen our presence in those territories and be even closer to the end users of our systems. .
