Polymeric semiconducting materials struggle to achieve fast charge mobility due to low structural order. In this work, five 1H‐indene‐1,3(2H)dione‐benzene structured halogenated solid additives namely INB‐5F, INB‐3F, INB‐1F, INB‐1Cl, and INB‐1Br with gradually varied electrostatic potential are designed and utilized to regulate the structural order of polymer donor PM6. Molecular dynamics simulations...
Lithium dendrites are easily generated for excessively‐solved lithium ions (Li+) inside the lithium metal batteries, which will lead serious safety issues. In this experiment, carbon spheres (CS) are successfully anchored on TiO2 (CS@TiO2) in the hydrothermal polymerization, which is filtrated on the commercial PE separator (CS@TiO2@PE). The negative charge in CS can suppress random diffusion of anions...
Carrier‐selective passivating contacts using transition metal oxides (TMOs) have attracted great attention for crystalline silicon (c‐Si) heterojunction solar cells recently. Among them, tantalum oxide (Ta2O5) exhibits outstanding advantages, such as a wide bandgap, good surface passivation, and a small conduction band offset with c‐Si, which is typically used as an electron‐selective contact layer...
Porous carbon is widely used in energy storage‐conversion systems, and the question of how to explore an efficient strategy for preparation is very significant. Herein, the flame retardant capability of (NH4)2SO4/Mg(OH)2 that contains gas phase‐heat absorption‐condensate phase components is assisted to carbonize coal tar pitch in air and obtain the porous carbon. The mechanism of stepwise inflaming...
The “shuttle effect” and slow redox reactions of Li‐S batteries limit their practical application. To solve these problems, a judicious catalyst design for improved battery cycle life and rate performance is essential. Herein, this issue is addressed by modifying the Li‐S battery separator using a 2D Fe2O3–CoP heterostructure that combines the dual functions of polar Fe2O3 and high‐conductivity CoP...
Dysfunctional transcription factors that activate abnormal expressions of specific proteins are often associated with the progression of various diseases. Despite being attractive drug targets, the lack of druggable sites has dramatically hindered their drug development. The emergence of proteolysis targeting chimeras (PROTACs) has revitalized the drug development of many conventional hard‐to‐drug...
Transition metal dichalcogenide (TMD)‐based 2D monolayer semiconductors, with the direct bandgap and the large exciton binding energy, are widely studied to develop miniaturized optoelectronic devices, e.g., nanoscale light‐emitting diodes (LEDs). However, in terms of polarization control, it is still quite challenging to realize polarized electroluminescence (EL) from TMD monolayers, especially at...
Structurally optimized transition metal phosphides are identified as a promising avenue for the commercialization of lithium–sulfur (Li–S) batteries. In this study, a CoP nanoparticle‐doped hollow ordered mesoporous carbon sphere (CoP‐OMCS) is developed as a S host with a “Confinement–Adsorption–Catalysis” triple effect for Li–S batteries. The Li‐S batteries with CoP‐OMCS/S cathode demonstrate excellent...
Lithium–sulfur (Li–S) batteries with high energy density and low cost are the most promising competitor in the next generation of new energy reserve devices. However, there are still many problems that hinder its commercialization, mainly including shuttle of soluble polysulfides, slow reaction kinetics, and growth of Li dendrites. In order to solve above issues, various explorations have been carried...
A cross‐linking strategy can result in a three‐dimensional network of interconnected chains for the copolymers, thereby improving their mechanical performance. In this work, a series of cross‐linked conjugated copolymers, named PC2, PC5, and PC8, constructed with different ratios of monomers are designed and synthesized. For comparison, a random linear copolymer, PR2 is also synthesized based on the...
The exploration of moiré superlatticesholds promising potential to uncover novel quantum phenomena emerging from the interplay of atomic structure and electronic correlation . However, the impact of the moiré potential modulation on the number of twisted layers has yet to be experimentally explored. Here, this work synthesizes a twisted WSe2 homotrilayer using a dry‐transfer method and investigates...
Electrochemical upgrading of ethanol to acetic acid provides a promising strategy to couple with the current hydrogen production from water electrolysis. This work reports the design of a series of bimetallic PtHg aerogels, where the PtHg aerogel exhibits a 10.5‐times higher mass activity than that of commercial Pt/C toward ethanol oxidation. More impressively, the PtHg aerogel demonstrates nearly...
Photoresponsive covalent organic frameworks (PCOFs) have emerged as attractive candidates for adsorption, but it is challenging to construct PCOF adsorbents due to structural order loss of covalent organic frameworks (COFs) after introducing photoresponsive motifs and/or tedious steps of postmodification. Here, a facile strategy is developed, by dispersing photoresponsive metal‐organic polyhedra (PMOP)...
Lithium metal anode (LMA) is puzzled by the serious issues corresponding to infinite volume change and notorious lithium dendrite during long‐term stripping/plating process. Herein, the transition metal nitrides array with outstanding lithiophilicity, including CoN, VN, and Ni3N, are decorated onto carbon framework as “nests” to uniform Li nucleation and guide Li metal deposition. These transition...
The 2D graphyne‐related scaffolds linked by carbon–carbon triple bonds have demonstrated promising applications in the field of catalysis and energy storage due to their unique features including high conductivity, permanent porosity, and electron‐rich properties. However, the construction of related scaffolds is still mainly limited to the cross‐linking of CaC2 with multiple substituted aromatic...

After iRGD peptide conjugation, the nanodots are loaded into dendritic...
Two‐dimensional (2D) mesoporous polymers, combining the advantages of organic polymers, porous materials, and 2D materials, have received great attention in adsorption, catalysis, and energy storage. However, the synthesis of 2D mesoporous polymers is not only challenged by the complex 2D structure construction, but also by the low yield and difficulty in controlling the dynamics of the assembly during...
Isolation‐Free Extracellular Vesicle Analysis
Tony Hu and co‐workers develop a rapid in situ copper nanoshell growth protocol using a gold nanorod seed enhanced plasmonic scattering, as the nanorod lattice structure promotes monocrystalline growth to generate geometries with superior plasmonic properties.

Sensitive detection of extracellular vesicles (EVs) as emerging biomarkers has shown great promises for disease diagnosis. Plasmonic metal nanostructures conjugated with molecules that bind specific biomarker targets are widely used for EVs sensing but involve tradeoffs between particle‐size‐dependent signal intensity and conjugation efficiency. One solution to this problem would be to induce nucleation...
