International collaboration in high pressure research

Published: 7 March 2018

The prestigious research institute in High Pressure Research, HPSTAR in Shanghai, recently invited Alexander Soldatov, Professor of Experimental Physics at Luleå University of Technology. In a course, he shared the excellence in high-pressure research of nanostructured carbon conducted at Luleå University of Technology.

– It is a recognition for the high pressure research at Luleå University of Technology that I am invited to present our research at HPSTAR, one of the leading institutes in high pressure research, with annual publications in Nature and Science. We will also launch a deeper cooperation with HPSTAR on high pressure research of carbon nanomaterials, says Alexander Soldatov, who has now been invited as an adjunct professor at HPSTAR, to start a deeper collaboration.

High Pressure Research

At HPSTAR in Shanghai, multidisciplinary research is conducted in the field of high pressure. It is a research area where material is studied under extreme conditions, in order to understand the material's limitations and possibilities. Advanced materials based on carbon are studied, such as the fuller and graphene, which have very beneficial properties in that they are flexible, lightweight and extremely strong. They can be used in demanding applications such as solar cells, to enhance and/or reduce friction and wear in composites.

Mobile test environments at the MAX IV laboratory

– At the moment we and HPSTAR in Shanghai together with the MAX IV laboratory are preparing a multi-million application to the Foundation for Strategic Research, SSF. The project is about developing test environments to be used at beam lines at MAX IV synchroton to run experiments and materials synthesis under extreme conditions – high pressure and/or high temperature. Because the sample size of these experiments is very small, the beam for sample characterization must be focused on an extremely small surface (at micrometer level), which is possible in a modern synchrotron, says Alexander Soldatov.

MAX IV is the world's brightest synchrotron radiation facility located in Lund, Sweden, where light can be focused on as little space as 30 – 100 nanometers. It opens up new opportunities for nano-level experiments.

– The test environment we want to build together with MAX IV and HPSTAR researchers will allow users of the facility to conduct experiments that have never been done before. In addition, the test environment becomes mobile, which allows it to be moved between different beam liines on MAX IV when different properties like structure and chemical bonds are to be studied in one and the same topic, says Alexander Soldatov, adding:

– Increased utilization of key research facilities such as MAX IV and ESS * by researchers at Luleå University of Technology is of great importance to our research. Therefore, this development project at MAX IV, led by Luleå University of Technology, will be an important part of this strategy, says Alexander Soldatov.

* = In Lund, the European Spallation Source (ESS) is being built, it is a unique material research facility based on the world's most powerful neutron source.
