The Greater Copenhagen Nanoscience Seminar

This seminar series is organized by the three nanoscience hubs located in the Copenhagen-Lund area. The aim is to to increase awareness about our mutual capabilities and to inspire collaborations.

Magnetic nanoparticles assembled to chain-like structures

Within a radius of just 25 km, the Copenhagen-Lund region features three strong hubs for nanoscience, with complementary strengths, scientific focus and capabilities:

  • the Nano-Science Center at the University of Copenhagen
  • NanoLund at Lund University
  • a cluster of groups at the Technical University of Denmark

Each hub comprises more than 30 research groups from several disciplines and several hundred staff, has developed advanced facilities for synthesis, characterization and fabrication of nanostructures, has a strong track record in translating discoveries into new technologies, and each is heavily engaged in education at all levels.

Our joint vision is to discover, invent and develop nanosystems with functionalities that emerge from the designed interaction between highly controlled and tunable building blocks.

By combining highly controlled building blocks from very different material systems to realize advanced, functional systems, we aim to jointly address challenges that are out of reach for an individual center.

The aim of this seminar series is to increase awareness about our mutual capabilities and to inspire collaborations.

Scheduled talks: once a month on a Friday at 15:15

24th September 2021: Maria Messing (NanoLund): Designing Nanoparticle-based Materials: From Sparks to Multifunctional Materials


Magnetic nanoparticles under the microscope

Smart nanomaterials with designed properties based on nanoparticles have the potential to revolutionize applications in, for example, magnetics and catalysis. But implementing nanoparticles’ potential for such applications requires realizing and understanding nanoparticles with controllable size, morphology, crystal structure and chemical composition on a large scale, at low costs and in a safe and environmentally friendly way.
Spark ablation is a method with high potential to fulfill the above declared requirements, especially for the production of pure metal and compound particles [1]. In this talk I aim to demonstrate some of the possibilities with aerosol-based nanotechnology. I will show how spark ablation can be used to produce nanoparticles with fully precise and tailored size, morphology and chemical composition [2, 3], and their controlled self-assembly into larger structures [4]. I will then show a few examples of the possible use of these particles in magnetic and catalytic applications.

Maria Messing is an associate professor in Materials Physics and Deputy Director of the Swedish Strategic Research Area NanoLund. She received her Ph.D. in 2011 from Lund University and is leading the research group engineered nanoparticles at the division of solid state physics in Lund. Marias research interest centers on developing of new types of nanoparticle-based materials with designed properties in a safe and sustainable manner using aerosol technology.



In order to achieve effective cross-fertilization, we will test a seminar format of two parts, where the first consists of 30 min lecture and 15 min questions and the second a 30 min “collaboration-space” where you are invited to stay on in Zoom for discussing ideas and possible collaborations. The total time for the event is between 75 and 90 minutes, depending on the topic and the arrangement with the speaker.


The Zoom link will be e-mail to all members of the three research environments. in case you are interested and have not received the link, please contact: Gerda [dot] Rentschler [at] ftf [dot] lth [dot] se
