Flexible electronics have gained great attention in recent years owing to their promising applications in biomedicine, sustainable energy, human‐machine interaction, and toys for children. Paper mainly produced from cellulose fibers is attractive substrate for flexible electronics because it is biodegradable, foldable, tailorable, and light‐weight. Inspired by daily handwriting, the rapid prototyping...
In this work, it is reported that large‐area (centimeter‐scale) arrays of non‐close‐packed polystyrene‐tethered gold nanorod (AuNR@PS) can be prepared through a liquid–liquid interfacial assembly method. Most importantly, the orientation of AuNRs in the arrays can be controlled by changing the intensity and direction of electric field applied in the solvent annealing process. The interparticle distance...
Electrodes made of composites with heterogeneous structure hold great potential for boosting ionic and charge transfer and accelerating electrochemical reaction kinetics. Herein, hierarchical and porous double‐walled NiTeSe–NiSe2 nanotubes are synthesized by a hydrothermal process assisted in situ selenization. Impressively, the nanotubes have abundant pores and multiple active sites, which shorten...
Atomically dispersed Zn moieties are efficient active sites for accelerating the electrode kinetics of carbons for sodium‐ion hybrid capacitors (SIHCs), but the low utilization and symmetric configuration of Zn single‐atom greatly hamper the Na ion storage capability. Herein, a molecular design strategy is employed to synthesize high‐density Zn single atoms with asymmetric Zn–N3S coordination embedded...
Contamination of water resources by toxic metals and opportunistic pathogens remains a serious challenge. The development of nano‐adsorbents with desired features to tackle this problem is a continuously evolving field. Here, magnetic mesoporous carbon nanospheres grafted by antimicrobial polyhexamethylene biguanidine (PHMB) are reported. Detailed mechanistic investigations reveal that the electrostatic...
Overall photocatalytic conversion of CO2 and pure H2O driven by solar irradiation into methanol provides a sustainable approach for extraterrestrial synthesis. However, few photocatalysts exhibit efficient production of CH3OH. Here, BiOBr nanosheets supporting atomic Cu catalysts for CO2 reduction are reported. The investigation of charge dynamics demonstrates a strong built‐in electric field established...
In article number 2100637, Vinayak P. Dravid, Jinsong Wu, and co‐workers perform a systematic study of WS2 nanoflakes as the anode for lithium‐ion and sodium‐ion batteries. It is found that compared to LIBs, SIBs exhibit a higher reversible sodium storage capacity and superior cyclability. The results show a direct correlation between the reaction dynamics of lithiated/sodiated WS2 nanoflakes and...
WS2 nanoflakes have great potential as electrode materials of lithium‐ion batteries (LIBs) and sodium‐ion batteries (SIBs) because of their unique 2D structure, which facilitates the reversible intercalation and extraction of alkali metal ions. However, a fundamental understanding of the electrochemical lithiation/sodiation dynamics of WS2 nanoflakes especially at the nanoscale level, remains elusive...
Photonic crystals (PCs) are ideal candidates for reflective color pigments with high color purity and brightness due to tunable optical stop band. Herein, the generation of PC microspheres through 3D confined supramolecular assembly of block copolymers (polystyrene‐block‐poly(2‐vinylpyridine), PS‐b‐P2VP) and small molecules (3‐n‐pentadecylphenol, PDP) in emulsion droplets is demonstrated. The intrinsic...
This paper demonstrates the ability of a CuCo2S4–reduced graphene oxide (rGO) composite to perform robust electrochemical performances applying to supercapacitors (SCs) and lithium ion batteries (LIBs). The first‐principle calculation based on density functional theory is conducted to study the electronic property of CuCo2O4 and CuCo2S4 and provide a theoretical basis for this work. Then, the 3D spinel‐structured...
Aqueous rechargeable zinc‐based batteries have sparked a lot of enthusiasm in the energy storage field recently due to their inherent safety, low cost, and environmental friendliness. Although remarkable progress has been made in the exploration of performance so far, there are still many challenges such as low working voltage and dissolution of electrode materials at the material and system level...
Carbon nanotubes (CNTs) are regarded as one of the most promising materials to manufacture high‐performance lithium batteries. This prospect is closely related to the construction of macroscopic architectures of CNTs. The superaligned CNT (SACNT) array is a unique kind of vertically aligned CNT array. Its highly oriented feature and strong intertube force facilitate the fabrication of macroscopic...
A multifunctional interlayer, composed of molybdenum diphosphide (MoP2) nanoparticles and a carbon nanotube (CNT) film, is introduced into a lithium–sulfur (Li–S) battery system to suppress polysulfide migration. Molybdenum diphosphide acts as the catalyst and can capture polysulfides and improve the polysulfide conversion activity during the discharge/charge processes. The CNT film acts as a conductive...
Codelivery of combinational antigenic peptides and adjuvant to antigen presenting cells is expected to amplify tumor specific T lymphocytes immune responses while minimizing the possibility of tumor escaping and reducing immune tolerance to single antigenic peptide. However, the varied hydrophobicities of these multivariant derived short antigenic peptides limit their codelivery efficiency in conventional...
A novel and simple strategy is developed to construct ultralight and 3D pure carbon nanotube (CNT) aerogels by the spontaneous expansion of superaligned CNT films soaked in a piranha (mixed H2SO4 and H2O2) solution, followed by cryodesiccation. The macroscopic CNT aerogels have an extremely low apparent density (0.12 mg cm−3), ultrahigh porosity (99.95%), high specific surface area (298 m2 g−1), and...
Nanotheranostics for biomedical imaging‐guided cancer therapy have attracted increasing interest due to their capabilities of both precise tumor diagnosis and high therapeutic efficacy. Among the diverse imaging models, fluorescence imaging have been extensively researched for their high sensitivity, simple operation, and low cost.

This article describes a novel supramolecular assembly‐mediated strategy for the organization of Au nanoparticles (NPs) with different shapes (e.g., spheres, rods, and cubes) into large‐area, free‐standing 2D and 3D superlattices. This robust approach involves two major steps: (i) the organization of polymer‐tethered NPs within the assemblies of supramolecular comblike block copolymers (CBCPs), and...
