Sodium-based dual ion batteries (SDIBs) have garnered significant attention as novel energy storage devices offering the advantages of high-voltage and low-cost. Nonetheless, conventional electrolytes exhibit low resistance to oxidation poor compatibility with electrode materials, resulting in rapid battery failure. In this study, for first time, a chlorination design SDIB, is proposed. Using ethyl methyl carbonate (EMC) representative, chlorine (Cl)-substituted EMC not only demonstrates...
Abstract 1,4‐Diazabicyclo[2.2.2]octane (dabco) and its derivatives have been extensively utilized as building units of excellent molecular ferroelectrics for decades. However, the homochiral dabco‐based ferroelectric remains a blank. Herein, by adding methyl (Me) group accompanied introduction homochirality to [H 2 dabco] 2+ in non‐ferroelectric dabco][TFSA] (TFSA=bis(trifluoromethylsulfonyl)ammonium), we successfully designed enantiomeric [ R S ‐2‐Me‐H . The two enantiomers show sequential...
The development of transition metal dichalcogenides has greatly accelerated research in the 2D realm, especially for layered MoS2 . Crucially, metallic monolayer is an ideal platform which novel topological electronic states can emerge and also exhibits excellent energy conversion storage properties. However, as its intrinsic phase, little known about nature 1T'-MoS2 , probably because limited phase uniformity (<80%) lateral size (usually <1 µm) produced materials. Herein, solution...
Van der Waals (vdW) layered materials with strong magnetocrystalline anisotropy have attracted significant interest as the long-range magnetic order in these systems can survive even when their thicknesses is reduced to 2D limit. Even though interlayer coupling between neighboring layers very weak, it has a determining effect on magnetism of atomic-thickness materials. Herein, new ferromagnetic material, namely, non-vdW CuCrSe2 nanosheets even-odd-layer-dependent ferromagnetism laminated...
Piezoelectric materials with inherent mechanical-electric coupling effect are a crucial family of functional in high-end information technology. For practical applications, the transverse piezoelectric performance (d31 or d32) is mainly considered, because this parameter vitally important index to characterize thin films. However, piezoelectricity films as key figure merit seldom mentioned molecular ferroelectrics. Herein, we report that new 1D halide perovskite ferroelectric...
Three-dimensional (3D) organic-inorganic lead halide hybrids have become a hot academic topic because of their various functional properties. However, 3D hybrid ferroelectrics are still very rare until now. Here, we report new perovskite-related ferroelectric, (EATMP)Pb2Br6 [EATMP = (2-aminoethyl)trimethylphosphanium]. Based on nonferroelectric CH3NH3PbBr3, by replacing PbBr6 octahedra with Pb2Br10 dimer edge-sharing as the basic building unit, expanded bromide perovskite analog was formed...
Two new homochiral 1D ABX<sub>3</sub>-type lead-halide perovskites exhibit dual dielectric and quadratic nonlinear optical switchings at high temperatures.
Abstract In correlated systems, intermediate states usually appear transiently across phase transitions even at the femtosecond scale. It therefore remains an open question how to determine these states—a critical issue for understanding origin of their behaviour. Here we report a surface coordination route successfully stabilize and directly image state in metal-insulator transition vanadium dioxide. As prototype material, capture unusual metal-like monoclinic room temperature that has long...

Fast ionic conductors are of great importance for novel technologies in high-performance and rechargeable energy storage components with reliable safety thermal stability. Here, we demonstrate a new concept the pillar effect to construct two-dimensional (2D) fast Li+ conductors. Our developed layered LixAg1-xCrS2 (0 < x 0.4) structure, larger-radius Ag+ served as "pillars" effectively rigidify interlayer channel, leads multi-ion concerted migration behavior thus contributes low activation...
[1,4-butanediammonium]BiI<sub>5</sub> is a lead-free organic–inorganic ferroelectric semiconductor showing high Curie temperature and small band gap.
The power conversion efficiency and stability of polycrystalline perovskite solar cells are compromised by grain-boundary-dominated ion migration. Herein, the grain boundaries CH3NH3PbI3 films were engineered using Ti2C quantum dots. dots had a strong interaction with Pb2+ I– ions, which retarded crystal growth, resulting in larger size less boundary films. Additionally, at could anchor ions passivate defects, increasing activation energy for hopping reducing trap density. In consequence,...
