Abstract Further increasing the critical temperature and/or decreasing stabilized pressure are general hopes for hydride superconductors. Inspired by low associated with Ce 4 f electrons in superconducting cerium superhydride and high yttrium superhydride, we carry out seven independent runs to synthesize yttrium-cerium alloy hydrides. The synthetic process is examined Raman scattering X-ray diffraction measurements. superconductivity obtained from observed zero-resistance state detected...

Nanoparticle assembly paves the way for unanticipated properties and applications from nanoscale to macroscopic world. However, study of such material systems is greatly inhibited due obscure compositions structures nanoparticles (especially surface structures). The atomically precise challenging, an with metal core sizes strictly larger than 1 nm has not been achieved yet. Here, we introduced on-site synthesis-and-assembly strategy, successfully obtained a straight-chain structure consisting Ag

The recent report of superconductivity in nitrogen-doped lutetium hydride (Lu-H-N) at 294 K and 1 GPa brought hope for long-sought-after ambient-condition superconductors. However, the failure scientists worldwide to independently reproduce these results has cast intense skepticism on this exciting claim. In work, using a reliable experimental protocol, we synthesized Lu-H-N while minimizing extrinsic influences reproduced sudden change resistance near room temperature. With quantitative...

The discovery of superconductivity in pressurized bilayer and trilayer nickelates have generated significant interest. However, their superconducting properties are often dependent on sample quality pressure conditions, complicating the interpretation underlying physics. Finding new systems with optimized bulk is therefore important for advancing our understanding these materials. Unlike cupates, where compounds typically exhibit highest transition temperature (Tc), nickelate La3Ni2O7 has...

Cu12Sb4S13 has aroused great interest because of its earth-abundant constituents and intrinsic low thermal conductivity. However, the applications are hindered by poor thermoelectric performance. Herein, it is shown that Gd substitution not only causes a significant increase in both electrical conductivity σ thermopower S but also leads to dramatic drop lattice κL. Consequently, large ZT reaches 0.94 at 749 K for Cu11.7Gd0.3Sb4S13, which ∼41% higher than value undoped sample. Rietveld...
