In a study, Merhan Sedrpooshan, Pau Ternero, Claudiu Bulbucan, Adam Burke, Maria Messing, and Rasmus Westerström introduce an innovative single-step method for fabricating magnetic alloy 1D nanostructures.
Alloying materials at the nanoscale opens up possibilities for tuning magnetic properties for various applications. In this approach, alloy FeCo nanoparticles with high magnetic moments are first generated by spark ablation of Fe and Co single-element electrodes in a carrier gas at ambient pressure, then directed towards a substrate using an electric field. Upon reaching the surface, the particles self-assemble into 1D parallel nanochains aligned with an applied magnetic field. The results show that the 1D geometry of these structures stabilizes magnetic moments along the chain axis, potentially enhancing the performance of magnetic materials needed for targeted drug delivery and microrobots.
An additional advantage of this technique, besides its single-step nature, is its environmentally friendly production, which eliminates the need for chemicals and catalysts in the synthesis process. This research, conducted in collaboration with researchers at Max IV Laboratory, involved imaging the magnetic domains within the 1D structures, providing valuable insights into the magnetic state of the structures at the nanoscale and opening new avenues for future advances.
The picture shows the schematic of the methodology, chemical composition of structures analyzed by STEM-XEDS, and identical-location SEM displaying the self-assembly process

By utilising quantum mechanics, a quantum computer can solve computational problems that today’s supercomputers cannot. But there are problems. As the circuits in quantum computers get bigger, they become more difficult to control. Researchers have demonstrated a new way to construct quantum circuits for individual light particles. This could enable larger and more complex circuits – crucial to unlocking the enormous computational power of quantum computers.

After a successful first round, another group of mentees ar joining the programme. The ten Ph D students taking part in this year’s mentorship programme gathered at LINXS Institute of Advanced Neutron and X-ray Science for a workshop, headed by career coach Tina Persson from passage2pro. Here, they learned about how to be coachable and have good discussions with their future mentors and practised the principles through role-play and games. Since the workshop, all students have met with their mentors and the programme is well underway. |

Optimise lab routines, minimise unnecessary consumption of lab consumables, recycle when possible, and improve user behaviour. That’s some of the improvements that can make the Lund Nano Lab greener, according to the project that Lund University Sustainability Fund is giving funding to, run by Process and tool responsible research engineer Sarah McKibbin.

We had the pleasure to, among a lot of other visits to the Lund Nano Lab, host a visit from Italy’s Area Science Park (ASP), along with the recently appointed Italian Ambassador to Sweden, Michele Pala. The Area Science Park connects several international scientific institutions in the Trieste area, with a particular focus on nanotechnology and life sciences. Following introductions, the group enjoyed an insightful tour of Lund Nano Lab, further fostering collaboration and knowledge exchange.

The jury was out for a long time. Entries have been evaluated in two categories: “Most aesthetically appealing image” and “Best visual communication of scientific content”. At last, we can announce the winners – and some special mentions to go with it, caused by the images leading us to think of steampunk, UFOs, Minecraft, and brutalism architecture, to mention a few.

Within WISE (Wallenberg Initiative Materials Science for Sustainability), Lund University has been allocated support for the coming five years for recruiting guest professors via a continuous process.
WISE also has a call for Industry PhD students and postdocs, which will open on August 12th with a deadline of November 19th.
To bridge the gap between academic research and innovation in Materials Science for Sustainability, the Knut and Alice Wallenberg Foundation funds Proof of Concept, call opening on 2 September.
If you have good ideas for guest professors related to Material Sciences, and/or for industrial PhD or postdoc projects (especially if you already have an industrial partner in mind), please contact the WISE university representatives Kimberly Thelander and Anders Mikkelsen.
Keep posted on the WISE website

WASP and WISE have just announced two new funding calls for joint projects. The joint calls aim to initiate, expand and strengthen the collaboration between WASP and WISE (see attached pre-call information).
To help facilitate the development of possible joint project ideas/applications, the LU eScience Hub working together with WASP@LU and WISE@LU is arranging a fika-to-fika meeting in Lund on 4 September to introduce everyone to the new WASP and WISE joint project calls.
The meeting will include presentations of both WASP and WISE (including both the national picture and a description of local activity) together with presentations about the new calls. The schedule will also include time for breakout group discussions to help develop ideas for joint proposals.
All interested researchers at LU are welcome. One can register for the event by signing up at the link below:
Early registration is strongly encouraged! |

At Medicon Village June 24-27, the NNT (2024) NIL-ID takes place. The combined NNT and NIL Industrial Days conference is dedicated to nanofabrication, Nanoimprint, Nanoprinting and industrial applications. This will be a unique opportunity to get an update of the state-of-play but also to establish contacts with the large eco-system on nanofabrication.

This year, the theme for the meeting is: Nano and New Frontiers in Computing – technologies and insights in biology, materials, light and quantum.
The NanoLund Annual Meeting, where we hope to see you all, takes place on 8 October at the Scandic Star Hotel in Lund. Program chairs Martin Leijnse and Jonas Tegenfeldt are working on an exciting program.
The programme features invited talks, poster pitches, and scientific presentations on new materials for neuromorphic computing, AI-driven material discovery, quantum computing, quantum simulation, bio-inspired computing, AI-based image analyses, and much more.
