X-ray diffraction is extremely powerful to study the structure of well-ordered, crystalline materials. In this paper, researchers from the Catalysis Section, NAFUMA, the Swiss Norwegian Beamlines, and Haldor Topsoe A/S take it one step further, by developing models for advanced diffraction studies of a disordered material, namely the beta zeolite. Despite the tremendous structural complexity caused by the disorder, these new models make it possible to resolve the degree of deactivation of the zeolite catalyst from a single diffractogram.

In-situ TEM experiments shows that the tendency for elemental mixing- or segregation to occur in Pt–Rh nanoparticles depends on the nanoparticle size and temperature. The smaller nanoparticles (≲13 nm) are stable in the solid solution configuration over the entire studied temperature range. Larger nanoparticles (≳13 nm) tends to segregate when cooled to room temperature. The results are of importance to understand the thermodynamics of this specific Pt–Rh nanoparticle system and it add value towards applications like catalysis, whereof e.g. supported Pt–Rh nanoparticles are attractive candidates for NH3 slip abatement processes.
New chemical transformations can be catalyzed with molecular gold compounds or gold nanoparticles. Researchers at the catalysis group have reported a simple and robust protocol for the synthesis of gold(III) compounds that are crucial for the development of these catalytic reactions. The synthesis utilizes heating in a microwave oven, and produces a number of new compounds, quickly and cleanly, in a one-step process.
Dense ceramic oxygen transport membranes (OTMs) combining high oxygen flux with chemical and mechanical stability find numerous applications in industrial processes where oxygen is extracted from air. In the present publication, Sintef Industry and The Electrochemistry group at SMN have collaborated in a project financed by the Research Council of Norway (CLIMIT 268450) rationalizing the performance limitation of OTMs based on state-of-the-art ceramic composite system.
Heterogeneous catalysis is a key enabling technology for the transition from a fossil-based society to a renewables-based scenario. Industrial catalysts are always shaped into millimeter-sized catalyst objects suitable for large scale industrial use. However, these catalysts invariably suffer from a loss of performance due to carbon deposits. It is vital to understand how these phenomena occur in these shaped objects, resolved both in time and space.
Joint research between the University of Oslo and Pennsylvania State University resulted in the development of a toolset necessary to understand the chemical changes in amorphous battery materials at atomistic level. This work has been recently published at Chemistry of Materials and has been selected for a cover page of the corresponding issue.
Nanocomposite materials consist of nanometer-sized quantum objects such as atoms, molecules, voids or nanoparticles embedded in a host material. These quantum objects can be exploited as a superstructure, which can be designed to create material properties targeted for specific applications.
Connecting diverse topics in chemistry, the difference between learning and doing science is not always as clear cut - especially when you apply new tools to open unexplored learning paths.
From June 1 you must use a parking app at UiO!
UiO:Life Science and vice-rector for research and innovation Per Morten Sandset invite all employees at UiO to breakfast meetings 27 May, 28 May, 29 May and 5 June at 8–9 AM.
As the first country, Norway has signed an agreement with Elsevier that ensures that Norwegian researchers can publish open access at no extra cost in most of Elsevier's journals.
There is no doubt that Australia and Japan are two different countries in many ways, for instance from the point of view of their climate, resources, landscape. Such differences are important when considering which renewable energy sources are appropriate to invest into.
Professor Knut Willem Ruyter has been appointed as academic ombud at the University of Oslo for the next three years. The ombud is independent of the organisation and will, among other things, provide guidance and advice to academic employees who find themselves in difficult research ethical situations.
Diabetes, organ donation, consciousness, the immune system, evidence in rape cases, mental illnesses, medicinal plants and cancer. These are societal challenges that will be examined in interdisciplinary life science research groups at the University of Oslo.
The University of Oslo’s research leads to new knowledge and innovations. However, our students make the greatest long-term impact for society. See our film "Connecting people and disciplines to solve complex problems".
UiO:Life Science shall recruit, educate and develop talents. Before Christmas the initiative announced that students could apply for summer research projects. The board has decided that as many as 66 students will be offered a project in 2018.
Thanks to all who attended Oslo Life Science – Investing in health and environment – 12–15 February 2018. See pictures and watch videos from the events. We hope to see all of you again at Oslo Life Science 2019.
Six new teams have been admitted to UiO´s innovation programme SPARK Norway. They will develop their ideas within health-related life sciences for the benefit of patients and society.
