Invar alloy has a wide range of applications in aerospace and precision instruments. However, the microstructure evolution during rapid solidification is not yet fully understood. In this study, with undercooling ranging from 5 K to 231 was investigated using optical microscopy, EBSD, TEM techniques. The results show that, as increased 181 K, transitioned large dendrites columnar grains finally small equiaxed grains. When ranged 193 grain size suddenly before continuing decrease further...
In this work, Bi2Te3 nanocrystals were synthesized via a hydrothermal method. They treated by spark plasma sintering (SPS) at 350 °C and further annealed between 500 °C. The crystal structures morphologies of these samples characterized X-ray diffraction (XRD), scanning electron microscopy (SEM), high-resolution transmission (HRTEM) measurements. SEM observation indicates an obvious increase particle size with increasing annealing temperature, but the grain estimated from HRTEM broadening...
We theoretically address the coupling between trimer lattices and reveal existence of stable multiple edge interface states. It is shown superlattice can provides a tunable number topologically protected states depending on strength topological phase connecting lattices. Dynamics transport properties are also investigated, Due to interference linear modes with different propagation constants, oscillations resulted from in finite trimerized waveguide arrays observed give rise optical...
We theoretically address the coupling between trimer lattices and reveal existence of topologically protected multiple edge interface states. It is shown superlattice can provides a tunable number states depending on strength topological order connecting lattices. Dynamics state propagation also investigated, property in finite modeled waveguide arrays give rise to robust optical functionalities.
Owing to its topological properties and band collapse, Floquet helical photonic lattices have gained increasing attention as a purely classical setting realize the optical analogues of wide variety quantum phenomena. We demonstrate both theoretically numerically that light propagation in an appropriately designed superlattice can exhibit spatial Zitterbewegung effect, i.e., quiver oscillatory motion beam center mass around mean trajectory, one- two-dimensional cases. The lattice spacing...
Abstract Medical antibacterial textiles play a vital role in tackling the issue of bacterial infection. Traditional surgical sutures face significant challenges due to wound infection caused by bacteria and breakage scars poor suture strength. Therefore, new high-strength preparation strategy with wide clinical applicability was highly desired. In this study, biodegradable quaternary ammonium salt (QAS)/polylactic acid (PLA) core-spun yarn excellent mechanical properties prepared conjugated...
Nominal stoichiometric NaxCo2O4 (x = 1.0, 1.2, 1.4, 1.6, 1.8, and 2.0) polycrystals were synthesized by a solid-state reaction method. They further pressed into pellets the spark plasma sintering. The crystal structure morphology of samples characterized X-ray diffraction scanning electron microscopy measurements. Good crystallinity layered structures observed for all samples. Positron annihilation measurements performed as function Na content. Two lifetime components are resolved. τ1 is...
