Octupole excitation: Research provides direct evidence for rare, pulsing pear shapes in gadolinium nuclei source:University of SurreyFor the first time, scientists have acquired direct evidence of rare, pulsing pear-shaped structures within atomic nuclei of the rare-earth element gadolinium, thanks to new research led by the University of Surrey, the National Physical Laboratory (NPL) and the IFIN-HH research institute in Bucharest, Romania.The study, published in Physical Review Letters, provides definitive proof of a strong collective "octupole excitation" in the nucleus of ga...

source: Phys.orgSuperconductivity, which entails an electrical resistance of zero at very low temperatures, is a highly desirable and thus widely studied quantum phenomenon. Typically, this state is known to arise following the formation of bound electron pairs known as Cooper pairs, yet identifying the factors contributing to its emergence in quantum materials has so far proved more challenging.Researchers at Princeton University, the National High Magnetic Field Laboratory, Beijing Institute of Technology and the University of Zurich recently carried out a study aimed at better understanding...

Crystal Structures, Phase Transition, and Optical Properties of Two Rare Earth Borate Fluorides: α- and β-BaGdBO3F2 source:ACS PublicationsBorate materials possess diverse crystal structures and exhibit outstanding physical properties, making them highly suitable for optical applications. In this work, two new compounds, α-BaGdBO3F2 and β-BaGdBO3F2, were synthesized by the high-temperature solid solution method and a temperature-controlled phase transition from α-BaGdBO3F2 to β-BaGdBO3F2 was observed. In the crystal structures of α-BaGdBO3F2 and β-BaGdBO3F2, the [BO3] basic building unit ...

source:University of PennsylvaniaFrom smartphones to wind turbines, rare earth elements (REEs) are an essential part of the hardware in many advanced technologies. These elements, which include the lanthanides along with scandium and yttrium, are the backbone of industries that rely on unique properties such as luminescence, magnetism and catalytic ability. In fact, as our world moves toward more sustainable energy solutions and increasingly sophisticated technologies, the demand for REEs is projected to grow substantially.There's one catch, however: REEs are difficult to extract and even ...
