AIM Conference in Bressanone

From 09. - 12.02.2025 Jonas Bugase and Yahya Shubbak participated in the 5th AIM conference (Advances in Magnetics) in Bressanone (Italy). Jonas Bugase presented a talk entitled "Controlled transport of magnetic cuboidal particles in dynamic potential energy landscapes for lab-on-chip applications", Yahya Shubbak presented "Magnetophoretic distinction of differently surface-functionalized magnetic microparticles by close-to-surface transport in a quiescent liquid".

Beamtime at BESSY II in Berlin

Between July 2024 and January 2025, the entire working group, led by Adrian Krone, spent six weeks measuring at the U125-2_NIM beamline of the electron storage ring BESSY II. The aim of this project is the precise and absolute mapping of the hydrogen molecule, a representation in which the photon emission spectrum is plotted as a function of the excitation energy. Due to the experimentally difficult to access UV/VUV spectral range, the high precision, the size of the excitation range and the desire to provide this map in absolute interaction cross-sections, many weeks of time were invested in this mammoth project.
