The detrimental growth of lithium dendrites and unstable solid electrolyte interphase (SEI) inhibit the practical application lithium-metal batteries. Herein, atomically dispersed cobalt coordinate conjugated bipyridine-rich covalent organic framework (sp2 c-COF) is explored as an artificial SEI on surface Li-metal anode to resolve these issues. single Co atoms confined in structure COF enhance number active sites promote electron transfer COF. synergistic effects Co─N coordination strong...
High-entropy alloy nanoparticles (HEANs) possessing regulated defect structure and electron interaction exhibit a guideline for constructing multifunctional catalysts. However, the microstructure–activity relationship between active sites of HEANs electrocatalysts is rarely reported. In this work, distributed on multi-walled carbon nanotubes (HEAN/CNT) are prepared by Joule heating as an example to explain mechanism trifunctional electrocatalysis oxygen reduction, evolution, hydrogen...
Wearable electronics with flexible, integrated, and self-powered multi-functions are becoming increasingly attractive, but their basic energy storage units challenged in simultaneously high density, self-healing, real-time sensing capability. To achieve this, a fully flexible omni-healable all-hydrogel, that is dynamically crosslinked PVA@PANI hydrogel, rationally designed constructed via aniline/DMSO-emulsion-templated situ freezing-polymerization strategy. The sheet, not only possesses...
Abstract Catalysts that can promote the hydrogen evolution reaction (HER) and oxygen (OER) are in demand for efficient water splitting. Here, a general practical UV‐induced synthesis of noble metal catalysts supported on reduced electrochemical graphene oxide (M‐rEGO, M = Ir, Pt or Pd) is proposed. The use EGO with low degree oxidation generation highly reducing isopropanol radical from added acetone crucial this one‐step, one‐pot synthesis. Using Ir as model material, vacancies rEGO allow...
High-entropy alloy (HEA) nanoparticles are rising as promising catalysts but face challenges in both facile synthesis and correlation of the structure with properties. Herein, utilizing highly reductive carbon-centered isopropyl alcohol radicals generated by UV irradiation, we report a simple yet robust wet chemical method to synthesize HEA under ambient conditions. These isopropanol verified electron paramagnetic resonance spectroscopy impose very large overpotentials reduce diverse metal...
Carrier mobility and density are intrinsically important in nanophoto/electronic devices. High-dielectric-constant coupled polarization-field gate ferroelectrics frequently studied partially capable achieving large-scale tuning of photoresponse, but their light absorption carrier seem generally ineffective. This raises questions about whether a similarly high-dielectric-constant paraelectric dielectric could enable how the principles involved be established. In this study, by deliberately...
Abstract Energy storage ceramic capacitors advance in high power density and working voltage, but challenge simultaneously large recoverable energy ( W rec ), efficiency η good thermal stability. To achieve this, a novel lead‐free system (1‐ x )(Bi 0.5 Na )TiO 3 ‐ (BaZr 0.3 Ti 0.7 O ) [(1‐ )BNT‐ BZT] was explored by tailoring the ferroelectric relaxor states. The introduction of BZT gradually promotes transformation states into at around room temperature for = 0.3‐0.5 that presents pinched...

A new mechanism of host-sensitized energy transfer was proposed to describe the luminescence dynamics behaviors between excitons and activators. This provides a promising path explore single-phase white light-emitting phosphors.
Thin, flexible, and electrically conductive films are in demand for electromagnetic interference (EMI) shielding. Two-dimensional NbSe2 monolayers have an electrical conductivity comparable to those of metals (106–107 S m–1) but challenging high-quality scalable production. Here, we show that electrochemical exfoliation flake powder produces on a large scale (tens grams), at high yield (>75%, monolayer), with average lateral size (>20 μm). The as-exfoliated monolayer flakes easily dispersed...
