2020.06.26 IFJ PAN scientists together with colleagues from the University of Milano (Italy) and other countries confirmed the need to include the three-nucleon interactions in the description of electromagnetic transitions in the 20O atomic nucleus. Vital for validating the modern theoretical calculations of the nuclear structure was the application of state-of-the-art gamma-ray detector systems and the newly developed technique for measurements of femtosecond lifetimes in exotic nuclei produced in heavy-ion deep-inelastic reactions.
2020.06.24 Scientists working at the Department for Functional Nanomaterials at the Institute of Nuclear Physics of the Polish Academy of Sciences designed and synthesized a functional ternary Pt/Re/SnO2/C catalyst as an anode material in a direct ethanol fuel cell. It was possible by synthesizing platinum, rhenium and tin oxide nanoparticles of a spherical shape and ensuring physical contact between them. This finding will lead to the production of more efficient, greener and cheaper fuel cell catalysts.
2020.06.17 Ultracold atoms trapped in appropriately prepared optical traps can arrange themselves in surprisingly complex, hitherto unobserved structures, according to scientists from the Institute of Nuclear Physics of the Polish Academy of Sciences in Cracow. In line with their most recent predictions, matter in optical lattices should form tensile and inhomogeneous quantum rings in a controlled manner.
2020.06.03 Scientists from IFJ PAN in cooperation with researchers from the Nara Women’s University (Japan) and the Jagiellonian University (Poland) took another important step towards building a functional quantum computer. Using material containing terbium ions and dedicated experimental tools, they performed a detailed analysis of dynamic magnetic properties in individual molecular magnets concerning their orientation in a magnetic field. Discovered strong anisotropy of these properties is vital in the construction of molecular electronics components.
2020.05.28 Polish scientists working in Poland, France and USA explained the mysterious β-delayed proton decay of the neutron halo ground state of 11Be. Studies within the SMEC model suggest the existence of collective resonance, carrying many characteristics of a nearby proton-decay channel, which explains this puzzling decay. It was argued that the appearance of such near-threshold resonant states is a generic phenomenon in any open quantum system, in which bound and unbound states strongly mix.
