Sequential Sol‐Gel Self‐Assembly and Nonclassical Gel‐Crystal Transformation of the Metal‐Organic Framework Gel

The whence and whither of the metal-organic framework gel. The sequential sol-gel self-assembly and the nonclassical gel-crystal transformation of the UiO-66(Zr) gel are disclosed. The unprecedented intermediate materials during the overall evolutionary processes are prepared “frame-by-frame”. Abstract Metal-organic framework (MOF) gel, an emerging...

Polymerization‐Induced Self‐Assembly: An Emerging Tool for Generating Polymer‐Based Biohybrid Nanostructures

This review gives an overview about recent developments in the formation of polymer-based biohybrid nanostructures (PBBNs) via polymerization-induced self-assembly (PISA). PISA outperforms traditional self-assembly techniques regarding efficiency, versatility, simplicity, reproducibility, and nanoparticle yields. Different biohybrid nanostructure architectures...

3D Printed Solid Polymer Electrolytes with Bicontinuous Nanoscopic Domains for Ionic Liquid Conduction and Energy Storage

This paper reports an efficient process for the fabrication of 3D-printed solid polymer electrolytes (SPEs) using photopolymerization-induced microphase separation, enabling control over material nanostructure. The resulting nanoscale bicontinuous structures impart high modulus and high ionic conductivity to SPEs, while 3D printing enables on-demand...

Hollow‐Particles Quasi‐Solid‐State Electrolytes with Biomimetic Ion Channels for High‐Performance Lithium‐Metal Batteries

In this work, hollow UiO-66 sphere with biomimetic ion channels based quasi-solid-state electrolytes is prepared. The system is inspired by K+/Na+ ion channels in cell membranes, where biomimetic ion channels formed by the open Zr4+ site can spontaneously bind anions, leaving Li+ as the only mobile species. Meanwhile, the hollow structures can incorporate...

Activated FeS2@NiS2 Core–Shell Structure Boosting Cascade Reaction for Superior Electrocatalytic Oxygen Evolution

In ideal conditions, the continuous intermediate reactions in oxygen evolution reaction (OER) require active sites with high, moderate, and low Fe/Ni ratios, as well as gradient spatial distribution of them. Here, activating FeS2@NiS2 core–shell structure results in a shell of FexNi1-xOOH with gradient Fe/Ni ratios, thus realizing cascade OER with superior...

Dynamic Pluronic F127 Crosslinking Enhancement of Biopolymeric Nanocomposites for Piezo‐Triboelectric Single‐Hybrid Nanogenerators and Self‐Powered Sensors

Dynamically robust biopolymeric nanocomposite triboelectric nanogenerators/piezoelectric nanogenerators/hybrid devices with excellent mechanical and electrical properties are designed based on biocompatible BaTiO3 and multiwalled carbon nanotubes crosslinked within a bacterial cellulose matrix by Pluronic F127. The electrical output performance of the...

Generalized Encapsulations of ZIF‐Based Fe–N–C Catalysts with Controllable Nitrogen‐Doped Carbon for Significantly‐Improved Stability Toward Oxygen Reduction Reaction

Development of highly-catalytic and long-term stable Fe–N–C catalyst using a controllable and efficient N–C coating strategy. The correlation between the thickness of N–C coatings and electrochemical performance is investigated. The stability improvement mechanism of N–C coating is identified to reduce carbon corrosion and iron leaching. Abstract...

Molecularly Hybridized Conduction in DPP‐Based Donor–Acceptor Copolymers toward High‐Performance Iono‐Electronics

Demonstrated is a copolymerization strategy to yield a series of DPP-based mixed ionic–electronic conductors and their performance in field effect and electrolyte-gated transistor devices. It is shown that well-balanced conduction at the molecular level in conjugated polymers is critical for optimizing figures of merit in organic electronics. Using...

Boosting Activity and Selectivity of UiO‐66 through Acidity/Alkalinity Functionalization in Dimethyl Carbonate Catalysis

Acidity/alkalinity functionalized MOFs into dimethyl carbonate catalysis are first introduced, and the Lewis acidic Pd-NO2-UiO-66 exhibits excellent catalytic performance. In addition to affecting the interaction of Pd(II) and support, the NO2 group has a dominant role in the chemisorption of MN and CO for generating the intermediates COOCH3 *, leading...
