A new short-lived neutron-deficient isotope Np220 was synthesized in the fusion-evaporation reaction Re185(Ar40,5n)Np220 at gas-filled recoil separator SHANS. Based on measurement of correlated α-decay chains, decay properties with Eα=10040(18) keV and T1/2=25−7+14 μs were determined, which are good agreement theoretical predictions. From experimental results coupled recently reported data Np219,223, systematics for Np isotopes around N=126 established, allows us first time to test...
The competition among different phases in perovskite manganites is pronounced since their energies are very close under the interplay of charge, spin, orbital and lattice degrees freedom. To reveal roles underlying interactions, many efforts have been devoted towards directly imaging phase transitions at microscopic scales. Here we show images charge-ordered insulator (COI) transition from a pure ferromagnetic metal with reducing field or increasing temperature strained phase-separated...
The nodal-line semimetals have attracted immense interest due to the unique electronic structures such as linear dispersion and vanishing density of states Fermi energy approaching nodes. Here, we report temperature-dependent transport scanning tunneling microscopy (spectroscopy) [STM(S)] measurements on semimetal ZrSiSe. Our experimental results theoretical analyses consistently demonstrate that temperature induces Lifshitz transitions at 80 106 K in ZrSiSe, which anomalies same...

Visual observation scanning electron microscopy verified that lacked trichomes on leaves...
Background: Long non-coding RNAs (lncRNAs) are crucial factors affecting the occurrence, progression and prognosis of gastric cancer. Disulfidptosis, a type programmed cell death, results from abnormal accumulation disulfide bonds in high-SLC7A11 cells. Research have demonstrated that upregulated SLC7A11 is common human cancers, but effect disulfidptosis on cancer remains unclear. It great significance to recognize -related lncRNAs (drlncRNAs) develop risk signature with prognostic value...

Magnetic skyrmions are topologically non-trivial spin structure, and their existence in ferromagnetically coupled multilayers has been reported with disordered arrangement. In these multilayers, the heavy metal spacing layers provide an interfacial Dzyaloshinskii-Moriya interaction (DMI) for stabilizing at expense of interlayer exchanging coupling (IEC). To meet functional requirement ordered/designable arrangement, this work, we proposed experimentally demonstrated a scenario skyrmion...
