Ferromagnetism and the Kondo effect are crucial for 3d electrons to become spin-separated heavy at same time.
Since its first identification in 1894 during the third pandemic Hong Kong, there has been significant progress understanding lifestyle of Yersinia pestis , pathogen that is responsible for plague. Although we now have some pathogen’s physiology, genetics, genomics, evolution, gene regulation, pathogenesis and immunity, are many unknown aspects disease development. Here, focus on knowns unknowns related to Y. We notably key physiologic virulence traits important mammal-flea-mammal life...
Abstract Dielectric nanomaterials have attracted significant attention in the realm of micro- nano optics owing to simultaneous low ohmic loss and distinctive electromagnetic resonance characteristic. However, achieving both ultra-narrow multi-band band perfect absorption effects simultaneously has been challenging due weak magnetic response within traditional dielectric metamaterials. In this work, employing finite-time domain differential method for simulation calculations, a absorber...
The interplay among topology, crystal symmetry, magnetic order, and strong electron correlation can give rise to a plethora of exotic physical phenomena. ZrSiS family is known as typical topological Dirac semimetals, them $\mathit{Ln}\mathrm{SbTe}$ ($\mathit{Ln}$ denotes lanthanide) compounds exhibit intriguing characteristics due the presence $\mathit{Ln} 4f$ electrons, resulting in quantum states unique properties.

Abstract The physical mechanism driving the γ – α phase transition of face-centre-cubic (fcc) cerium (Ce) remains controversial until now. In this work, high-quality single crystalline fcc–Ce thin films were grown on Graphene/6 H -SiC(0001) substrate, and explored by XRD ARPES measurement. spectra showed a clear at T − ≈ 50 K, which is retarded strain effect from substrate comparing with (about 140 K) bulk Ce metal.

Abstract Olivine‐type LiFe y Mn 1− PO 4 (LFMP) is a promising cathode candidate with high energy density, chemical stability, and cost efficiency. However, an unidentified anomalous lithiation plateau (P II) often emerges between the 2+ /Mn 3+ Fe /Fe redox reactions, leading to decrease in density. Herein, it demonstrated that P II originates from couple, yet differs classical reaction due its lower operating voltage. During lithiation, Li + initially accumulates on particle surface, forming...
