3D Printed Template‐Directed Assembly of Multiscale Graphene Structures

Multiscale graphene architectures with five identifiable levels of structural hierarchy in length scale ranges from nanometer to centimeters (seven orders of magnitude) are created by an ingenious 3D printed template-directed assembly method, which show customizable mechanical properties and multifunctionalities. The integrated method also demonstrates...

Specific Adsorption Reinforced Interface Enabling Stable Lithium Metal Electrode

An organic surfactant of ammonium perfluoro(2-methyl-3-oxahexanoate) as an electrolyte additive is employed for lithium electrodes. Because of the adsorption of the additive anions and the adapted electrical double layer on the surface, the electrode kinetics is greatly promoted, thus enabling a stable lithium electrode. Abstract Lithium-metal...

Domain‐Confined Etching Strategy to Regulate Defective Sites in Carbon for High‐Efficiency Electrocatalytic Oxygen Reduction

Coupling sites of nitrogen dopants and intrinsic carbon defects (N/DC) are effectively constructed in metal-free carbon by domain-confined etching of endogenous metal oxides that are derived from the M-Nx moieties in precursors with the mediation of halides. The N/DC-enriched metal-free carbon exhibits an excellent ORR catalytic activity. This work...

Genetically Encoded Synthetic Beta Cells for Insulin Biosynthesis and Release under Hyperglycemic Conditions

A biocatalytic metal–organic framework-based, genetically encoded synthetic beta cell is engineered. Under hyperglycemic conditions, this synthetic cell can initiate programmed subcellular events, including glucose sensing, initiation of insulin gene transcription and translation, and finally excretion of functional insulin. Such a synthetic construct...

Photo‐Induced Dynamic Room Temperature Phosphorescence Based on Triphenyl Phosphonium Containing Polymers

Long-lived room temperature phosphorescence systems based on two polymer acceptors containing a triphenyl phosphonium side chain are developed. The phosphorescence performance is dependent on the grafting rates of the polymers. The visualization of real information and complete pattern after 365 nm UV irradiation is demonstrated based on these phosphorescence...

Nanodot‐in‐Nanofiber Structured Carbon‐Confined Sb2Se3 Crystallites for Fast and Durable Sodium Storage

Carbon-confined Sb2Se3 crystallites with nanodot-in-nanofiber structures are successfully fabricated through stepwise electrospinning, in situ substitution, and selenylation strategies. Benefiting from the synergistic effects of dual-carbon confinement and uniformly distributed nanosize Sb2Se3, the composite presents a highly efficient sodium storage...

Ni, Co Hydroxide Modified by Partial Substitution of OH– with Cl– for Boosting Ultra‐Fast Redox Kinetics up to 500 mV s−1 in Supercapacitors

A Cl− substituted Co, Ni layered hydroxide shows well-maintained redox peaks at an ultrahigh scan rate up to 500 mV s−1 and an outstanding rate performance because Cl− substitution increases the electric conductivity and interlayer H2O density, leading to ultrafast ion transport through the Grotthuss behavior. Abstract Metal oxides/hydroxides...

Localized Electron Density Redistribution in Fluorophosphate Cathode: Dangling Anion Regulation and Enhanced Na‐Ion Diffusivity for Sodium‐Ion Batteries (Adv. Funct. Mater. 4/2022)

Anionic Doping In article number 2109694, Hong Yu, Cheng-Feng Du, Xing-Long Wu, and co-workers develop Cl-doped Na3V2(PO4)2O2F (NVPO2−xClxF) as superior cathode material for sodium-ion batteries. In NVPO2−xClxF, Cl doping tunes the electronic structure and causes the electron redistribution on vanadium center/dangling anions. As a result, a revised...

Tumor Microenvironment Activated Chemodynamic–Photodynamic Therapy by Multistage Self‐Assembly Engineered Protein Nanomedicine

A tumor microenvironment-activable system via multistage self-assembly engineered protein-based nanomedicine containing cascade enzymes and photosensitizers is developed. Once triggered by the intratumoral reduction microenvironment, the aggregation effect is unlocked to expose cascade enzymes and recover the photosensitivity for realizing tumor-specific...

Sequential Assembly Tailored Interior of Porous Carbon Spheres for Boosted Water Decontamination through Peroxymonosulfate Activation

A sequential assembly approach is developed by simply changing the feeding interval of the carbon and silica precursors for preparing the porous carbon spheres with tunable type (i.e., hollow or solid) and size of interiors. The interior engineering of the carbon spheres significantly enhances their performance in catalytic water decontamination through...
