One-dimensional nanoscale epitaxial arrays serve as a great model in studying fundamental physics and for emerging applications. With an increasing focus laid on the Cs-based inorganic halide perovskite out of its outstanding material stability, we have applied vapor phase epitaxy to grow well aligned horizontal CsPbX3 (X: Cl, Br, or I their mixed) nanowire large scale mica substrate. The as-grown features triangular prism morphology with typical length ranging from few tens micrometers...
Magnetic hard nanocrystalline MnBi has been prepared by melt spinning and subsequent low temperature annealing. A coercivity of 2.5 T can be achieved at 540 K for with an average grain size about 20-30 nm. The iHc, mainly controlled the coherent magnetization rotation, shows a strong dependence on time grinding exhibits positive coefficient from 100 up to K. unique dependent behavior (magnetocrystalline anisotropy) relationship variations in crystal lattice ratio c/a temperatures.

Remarkable properties of layered metal dichalcogenides and their potential applications in various fields have raised intense interest worldwide. We report tens microns-sized ultrathin single crystal SnS2 flakes grown on amorphous substrates using a simple one-step thermal coevaporation process. X-ray pole figure analysis reveals that majority are oriented with the (0001) plane parallel to substrate preferred fiber texture. For few-layer-thick SnS2, Moire patterns 6-fold 12-fold symmetries...
The van der Waals (vdW) bond is traditionally believed to be orders of magnitude lower than the typical chemical (i.e., ionic, metallic, or covalent), and hence effects caused by a vdW interface are thought trivial. In this paper, investigating epitaxial growth mechanically soft perovskite on substrate, we obtained solid proof strong non-negligible interaction. experimental results illustrate formation cracks holes for relaxation strain as well lattice-constant-dependent angle evolution...
Bulk anisotropic composite magnets based on MnBi/Co(Fe) exhibiting the different morphology of soft magnetic phase were prepared by powder metallurgy processing. First, single-phase MnBi bulk produced with a maximum energy product [(BH)m] 6.3 MGOe at room temperature. The nanoscale was then added to form magnet. It observed that addition soft-phase nanoflakes causes dramatic coercivity reduction. However, nanowires enhanced magnetization without sacrificing coercivity. Nevertheless, kink...
Zero-knowledge succinct non-interactive arguments of knowledge (zk-SNARKs) are a powerful tool for proving computation correctness, attracting significant interest from researchers, developers, and users. However, the complexity zk-SNARKs has created gaps between these groups, hindering progress. Researchers focus on constructing efficient systems with stronger security new properties, while developers users prioritize toolchains, usability, compatibility. In this work, we provide...

Additionally, decoupled strategy is employed to separate magnetic fluid field functions from original system. Since only need solve several...
