Lithium metal batteries are regarded as promising alternatives to lithium ion batteries due to their high specific capacity. However, lithium dendrite growth during cycling causes safety problem and rapid capacity loss. Here, we report a composite Li anode composed (LYF) of metallic Li and trace amounts (1∼2 wt%) of two-dimensional YFδ. The lithiophilic nature of YFδ enables its homogeneous dispersion

In reactive-hot-pressed ZrB2–SiC–ZrC ceramics, ZrO2 was found to replace ZrC phase, hence leading to confusion in designing ultra-high-temperature ceramics (UHTCs). We employ high-precision X-ray diffraction and electron microscopies to reassess the phase behavior during entire reaction and densification and to reveal the evolution of multiphase relationship at different stages before reaching the

Flexible ferroelectric memories, endowing with high data storage density, provide a chance for the next-generation wearable electronics. Here, flexible inorganic Mn-doped BiFeO3 thin films were directly integrated on fluorophlogopite mica (F-Mica) substrates by an easy and low-cost all solution chemical solution deposition (AS-CSD) route. The integration of LaNiO3 buffer layer can improve the film

Electrocaloric effect (ECE) is promising in realizing solid-state cooling as an alternative to the conventional refrigeration with environmentally harmful coolant and low efficiency. High ECE in lead-free ferroelectric ceramics is highly desirable for the EC cooling. In this work, different from the researches that tune the ECE by conventional compositional design or external stress engineering, we

A novel Ag/g-C3N4/kaolinite composite photocatalyst was fabricated for the first time through a two-step assembly strategy by employing in situ calcination and a photodeposition process. The synthesized Ag/g-C3N4/kaolinite composite reached a higher degradation rate of ibuprofen (IBP) with a reaction rate constant of 0.0113 min−1 at an Ag content of 7% under visible-light irradiation, which was approximately

In the present work, the crystal structure, ferroelectric and dielectric properties of the dense single-phase Li2CaTa2O7 ceramics with A-site ordered double-layer Ruddlesden-Popper structures have been investigated by the experiments and first-principles calculations. A polar Pna21 phase was determined by the Rietveld refinement against the X-ray diffraction pattern at room temperature, and it was

Understanding the interface effect in dielectric nanocomposites is crucial to the enhancement of their performance. In this work, a data-driven interface design strategy based on high-throughput phase-field simulations is developed to study the interface effect and then optimize the permittivity and breakdown strength of nanocomposites. Here, we use two microscopic features that are closely related

Coaly graphite is an important natural graphite resource that derived from coal under a natural process that associated with igneous intrusion. Flake graphite is usually used for the chemical synthesis of graphene oxide (GO), the main precursor for preparation of graphene, but few papers pay attention to preparing GO using coaly graphite. In this paper, four kinds of natural coaly graphite with different

A new low-cost high-permittivity flexible nanocomposite consisting of a polyvinylidene fluoride (PVDF) matrix and fullerene-like tungsten disulfide nanoparticle (IF-WS2 NP) filler was fabricated via a simple solution route. A comprehensive investigation by X-ray diffraction, attenuated total reflection-infrared spectroscopy, and differential scanning calorimetry (DSC) showed that 0.5–1 vol% of IF-WS2

A novel facile technique is proposed for fabricating three-dimensional (3D) concave nanolens arrays on a silicon substrate. The technique leverages an inherent characteristic of the polymethyl methacrylate (PMMA) resist during inductively coupled plasma (ICP) etching. The tendency for plasma ions to accumulate at the edge of the PMMA resist helps create a local electric field that causes the ions to
