For eight weeks the summer students are now working on a research project at the Helmholtz Centre Berlin. Experienced scientists of the HZB will support them. On Thursday, 30 August, they will present their results.
This year, 282 young people from all over the world applied to take part in the HZB's summer program. But only 24 places are available. Now the selected students can start their project. They come from 14 different countries, including Egypt, China, Cuba, Russia and Thailand, and study STEM subjects in Bachelor's or Master's programmes at their home universities. For many, the summer student program is the first step into research.
"Once again this year, many HZB researchers have signed up with project ideas for summer students and agreed to intensively support the students," says Gabriele Lampert, who coordinates the summer student program. "I know that this also means additional work, but the experience from recent years also shows that it is often worth it for both sides. Because it happens again and again that summer students come back later, for example for a doctorate, as cooperation partners or users.
Finally, the summer students will present their results on 30 August 2019 at 11:00. Three students will give a short lecture, all others will explain their project with a self-designed poster.
- Spintronics at BESSY II: Real-time analysis of magnetic bilayer systemsSpintronic devices enable data processing with significantly lower energy consumption. They are based on the interaction between ferromagnetic and antiferromagnetic layers. Now, a team from Freie Universität Berlin, HZB and Uppsala University has succeeded in tracking, for each layer separately, how the magnetic order changes after a short laser pulse has excited the system. They were also able to identify the main cause of the loss of antiferromagnetic order in the oxide layer: the excitation is transported from the hot electrons in the ferromagnetic metal to the spins in the antiferromagnet.
- Too old for research at 60? From nuclear physics to papyrus researchA career in science can be personally fulfilling. However, this also means accepting the unpredictable: research topics may no longer receive funding, and laboratories may close. Heinz-Eberhard Mahnke experienced this first-hand when he had to seek new challenges in his early 60s. Today, the 81-year-old is still active in research, using non-destructive measurement methods to examine ancient artefacts of inestimable cultural value. Antonia Rötger spoke with this extraordinary researcher, whose curiosity and drive are truly inspiring.
- Electrocatalysts: New model for charge separation at the solid-liquid interfaceHydrogen is at the heart of the transition to carbon neutrality, as both an energy carrier and a reagent for green chemistry. However, large-scale production of hydrogen via electrolysis, as well as the production of many other chemical products, requires significantly cheaper and more efficient catalysts. A precise understanding of the electrochemical processes that take place at the interface between the solid catalyst and the liquid medium is highly useful for developing better electrocatalysts. In the journal Nature Communications, an European team has now presented a powerful model that determines charge separation at the interface, the formation of the electric double layer and local electric potential variations, and the resulting influence on the catalytic activity.
