Abstract Dielectric materials with high permittivity are strongly demanded for various technological applications. While polarization inherently exists in ferroelectric barium titanate (BaTiO 3 ), its can only be achieved by chemical and/or structural modification. Here, we report the room-temperature colossal (~760,000) obtained x Nd: BaTiO ( = 0.5 mol%) ceramics derived from counterpart nanoparticles followed conventional pressureless sintering process. Through systematic analysis of...

All-solid-state lithium metal batteries (ASSLiMB) have been considered as one of the most promising next-generation high-energy storage systems that replace liquid organic electrolytes by solid-state (SSE). Among many different types SSE, NASICON-structured Li1+xAlxGe2–x(PO3)4 (LAGP) shows high a ionic conductivity, stability against moisture, and wide working electrochemical windows. However, it is unstable when in contact with molten Li, hence largely limiting its applications ASSLiMB. To...

Although different metal-organic framework (MOF) membranes have been widely studied for gas separation, their application water treatment is still in its infancy. MOF with improved hydrophilicity and stability are particularly essential water/wastewater treatment. Herein, we successfully developed heterogeneous (Zn/Co-ZIF-L) composed of vertically standing leaf-like crystals Zn-ZIF-L grown situ onto porous ceramic supports, followed by the subsequent growth Co-ZIF-L. The show (WCA = 13.6 ±...

Dendrite growth under large current density is the key intrinsic issue impeding a wider application of Li metal anodes. Previous studies mainly focused on avoiding dendrite by building an additional interface layer or surface modification. However, mechanism and factors affecting for anodes are still unclear. Herein, we analyze causes growth, which leads us to suggest three-dimensional (3D) as promising approach overcome issues. A 3D composite anode was prepared from renewable carbonized...

To further improve the photocatalytic H2 evolution activity, NaNbO3 photocatalyts simultaneously possessing cubic crystal structure and 1D morphology have been successfully synthesized via a modified solvothermal strategy. During process of synthesis employing ethylene glycol as solvent, temperature fluctuation during autoclaving period is proposed to regulate grain growth without any other additives or calcinations. It demonstrated that structure-directing effect solvent enhanced in...

A flexible polymer nanocomposite has been developed via introducing Nd-doped BaTiO3 nanoparticles into the poly(vinylidene fluoride). This delivers a discharged energy density up to 12.5 J/cm3 under an electric field of 420 kV/mm with only small loading 1 vol.% Nd-BaTiO3. High density, mechanical flexibility, light weight, ease fabrication and low cost makes it attractive for advanced microelectronics electrical power systems.

The energy storage density of pure polymers is usually limited by their low intrinsic dielectric constants (εeff). Integrating polymer matrix with ceramic particles high εeff values has been one powerful approach to enhance the composites and thus density. In this study, we report a flexible polymer-based composite introducing Nd-doped BaTiO3 (NBT) nanoparticles (εeff over 3×105) into poly(vinylidene fluoride) (PVDF). phase PVDF its behavior could be adjusted varying NBT loadings.

Although inorganic all-solid-state Li-ion batteries (ASSLiBs) using stable oxide solid electrolytes are considered to be promising candidates for future energy storage devices, their relatively high cell impedance due the restricted contact area and interfacial stability results in unsatisfactory electrochemical performance fast capacity fading. The mechanism limiting cycle life such ASSLiBs still lack study hence understanding. To overcome this bottleneck, we prepared a bulk ASSLiB, where...

Photocatalytic technology is an attractive option for environmental remediation because of its green and sustainable nature. However, the inefficient utilization solar energy powder morphology currently impede practical application. Here, we designed a floatable photocatalyst by anchoring 0D Cu2(OH)PO4 (CHP) nanoparticles on 2D graphene to construct 0D/2D CHP/reduced oxide (rGO) aerogels. The CHP/rGO aerogels have interconnected mesopores that provide large surface area, promoting particle...
