Open AccessDiscovery of conjoined charge density waves in the kagome superconductor CsV3Sb5
The electronic instabilities in CsV3Sb5 are believed to originate from the V 3d-electrons on the kagome plane, however the role of Sb 5p-electrons for 3-dimensional orders is largely unexplored. Here, using reson...

Distribution of 14C and 3H in low level radioactive wastes generated by wet waste streams from pressurized water reactors
It is impossible to detect 14C and 3H by direct methods such as γ-spectroscopy because they are pure b-emitters and thus they are classified as hard to measure nuclides (HTM). In this paper the analysis results o...
