Here we report a comprehensive study of the crystal structure, resistivity, and ac magnetic susceptibility in single crystals La$_3$Ni$_2$O$_7$, with hydrostatic pressure up to 104 GPa. X-ray diffraction measurements reveal bilayer orthorhombic structure (space group $Amam$) at ambient transformation into tetragonal phase $I4/mmm$) critical $\sim$14 The transport dome-shaped superconducting region maximum $T_c$ 83 K 18.0 superconductivity is gradually suppressed when applying higher...
Strain rockburst is a severe failure phenomenon caused by the release of elastic strain energy in intact rocks under high-stress conditions. They frequently occur deep tunnels, causing significant economic losses, casualties, and construction delays. Understanding factors influencing this disaster significance for tunnel construction. This paper first proposes novel three-dimensional (3D) discrete element numerical analysis method considering full stress state based on bonded block model...

Compared with the linear isolation system, quasi-zero-stiffness (QZS) nonlinear system has characteristics of high static stiffness and low dynamic stiffness, which better low-frequency vibration performance. However, most existing QZS isolators only consider characteristic at equilibrium position achieved by parallel connection positive negative structures. To optimize performance a new device based on oblique springs vertical was proposed. The can not achieve but also expand interval...
Our experiment revealed that the addition of Janus nanosheets to polypropylene (PP) has a significant impact on viscoelasticity composite system. Specifically, when 0.10 wt% were added, complex viscosity system increased. However, we added less than 0.05 nanosheets, there was reduction in viscosity, which is known as non-Einstein phenomenon. The Cole–Cole plot showed nanosheet network structure did not have effect Additionally, used carbon dioxide foaming agent autoclave using modified PP...
Abstract In this paper, pure cubic chromium silicide (Cr 3 Si) hollow particles have been successfully synthesized through the solid-state reaction of sesquioxide, silicon powder and metallic lithium in an autoclave at 600 °C for 10 h. The as-prepared samples were characterized by means X-ray diffraction, field emission scanning electron microscopy transmission microscopy, which showed that phase Cr Si particles. Furthermore, oxidation resistance obtained sample was also investigated.
