Ionic conduction in a ferroelectric leads to anomalous polarization switching kinetics but prevents retention failure.
Abstract Collective ferroic orders in van der Waals (vdW) crystals are receiving increasing attention 2D materials research. The interplay between spatial quantum confinement and long‐range cooperative phenomena not only broadens the horizon of fundamental physics, but also enables new device paradigms functionalities built upon vdW heterostructures. Here, in‐plane ferroelectric properties thin flakes hybrid perovskite bis(benzylammonium) lead tetrachloride studied. ordering electric dipoles...
• Designed a five-tier nested experimental watershed for multi-scale water cycle study. Hydrological processes exhibit spatiotemporal scaling effect. Canopy leaf density has an exponential effect on rainfall interception. Surface runoff serves as major component of total in the humid zone.

The...
Piezoelectric materials convert mechanical stress to electrical energy and thus are widely used in harvesting wearable devices. However, the piezoelectric family, there two pairs of properties that improving one them will generally compromises other, which limits their applications. The first pair is strain voltage constant, second performance softness. Here, we report a molecular bond weakening strategy mitigate these issues organic-inorganic hybrid piezoelectrics. By introduction...
The continuous dimensional scaling of semiconductor and logic photoelectric device requires ferroelectrics to possess robust activity switchable polarization at the nanoscale. However, traditional such as oxide perovskites generally suffer from relatively large bandgap deteriorated ferroelectricity in ultrathin forms, while many transition metal dichalcogenides is related inter-layer effects, leading that only exists flakes with a certain layer number particular stacking forms. associated...
Abstract We present a case study using the TIGGE database for flood warning in Upper Huai catchment (ca. 30 672 km 2 ). ensemble forecasts from 6 meteorological centres with 10‐day lead time were extracted and disaggregated to drive Xinanjiang model forecast discharges events July‐September 2008. The results demonstrated satisfactory forecasting skills clear signals of floods up 10 days advance. occasionally show discrepancies both space. Forecasting quality could potentially be improved by...
Two-dimensional (2D) layered lead halide perovskites with large exciton binding energies, efficient radiative recombination, and outstanding environmental stability are regarded as supreme candidates for realizing highly compact ultralow threshold lasers. However, continuous-wave (CW) pumped lasing of 2D perovskites, the precondition electrically lasing, is still challenging. Here, we tackled this challenge by demonstrating emission in phenylethylammonium iodide [(PEA)2PbI4] embedded a...
Organic-inorganic hybrid perovskites with considerable dielectric differences near the phase transition are potential candidates as materials (PTMs). However, compared traditional PTMs, which require multiple switchable channels, so far show only switching behavior in constants. We herein report a new crystal design strategy and successful synthesis of two-dimensional perovskite (C6H5C2H4NH3)2MnCl4. In this perovskite, manganese chloride octahedron is field sensitive luminescent molecular...
Higher-order Weyl semimetal (HOWSM) is a fascinating topological phase that connects the nontrivial higher-order topology and semimetal. In this paper, we introduce novel termed double-Weyl semimetals (HODWSMs) through application of symmetry analysis minimal tight-binding model. This notable for its quadratic nodes located in ${k}_{z}=0$ plane other planes. Specifically, within phase, there sole pair nodes, distinguished by chiral charges $+2$ $\ensuremath{-}2$, respectively. The emergence...
Recently, higher-order topology has been expanded to encompass aperiodic quasicrystals, including those with eightfold or twelvefold rotational symmetry. The underlying mechanism for these high-order topological phases is generally protected by ${C}_{n}{\mathcal{M}}_{z}$ symmetry, resulting in the presence of $n$ corner states. However, this not applicable other ${C}_{2N}$ quasicrystals when $N$ an odd number. In work, we propose realization a second-order superconductor (SOTSC) within...
The synthesis of cm-scale buckypapers consisting an unusual stacking vertically aligned and randomly entangled Fe-filled carbon nanotubes is revealed through advanced high flow-rate Cl-assisted chemical vapour deposition approach. produced films show very attractive room-temperature coercivities as 1040 Oe (82 763 A m−1), much higher than those reported in previous reports. We attribute the coercivity to presence pinning effects due two CNT morphologies. coercivity, surface areas,...
One of the challenges in field carbon nanotubes (CNTs) is encapsulation a single crystalline phase ferromagnetic α-Fe.
Viscous boundary layer chemical vapor synthesis is a novel technique that uses the viscous between metallocene/Ar and rough surface to induce formation of radial CNT structures highly filled with ferromagnetic materials.
Nonsymmorphic symmetries play a significant role in the emergence of topological nontrivial phases some 2D materials. Herein, new material P21/m‐MoTe 2 with properties and nonsymmorphic is proposed. With help first‐principles calculations, it found that dynamically stable, has relatively high energetic stability. When spin–orbit coupling (SOC) ignored, this semimetal two intersects appearing on high‐symmetry line Γ–Y. Detailed symmetry analysis reveal they are protected by screw operator ....
