Healable stretchable conductive nanocomposites have received considerable attention. However, there has been a trade‐off between the filler‐induced electrical conductivity (σ) and polymer‐driven mechanical strength. Here significant enhancements in both σ and mechanical strength by designing reversible covalent bonding of the polymer matrix and filler‐matrix covalent bifunctionalization are reported...
Ultraviolet detection is of great significance due to its wide applications in the missile tracking, flame detecting, pollution monitoring, and so on. The nonlayered semiconductor γ‐Bi2O3 is a promising candidate toward high‐performance UV detection due to the wide bandgap, excellent light sensitivity, environmental stability, nontoxic and elemental abundance properties. However, controllable preparation...
Antimony sulfide is attracting enormous attention due to its remarkable theoretical capacity as anode for sodium‐ion batteries (SIBs). However, it still suffers from poor structural stability and sluggish reaction kinetics. Constructing covalent chemical linkage to anchor antimony sulfide on two‐dimension conductive materials is an effective strategy to conquer the challenges. Herein, Ti3C2‐Sb2S3 composites...
Multiferroics with simultaneous electric and magnetic orderings are highly desirable for sensing, actuation, data storage, and bio‐inspired systems, yet developing flexible materials with robust multiferroic properties at room temperature is a long‐term challenge. Utilizing water‐soluble Sr3Al2O6 as a sacrificial layer, the authors have successfully self‐assembled a freestanding BaTiO3‐CoFe2O4 heteroepitaxial...
Discovering new drugs and improving action mechanisms is a promising strategy to overcome chemotherapy ineffectiveness caused by cancer cell apoptosis resistance. Natural products (like cyclic lipopeptides, CLPs) are potential sources of nonapoptotic cell death inducers and can form diverse supramolecular structures, closely relating to their bioactivities. Herein, it is found for the first time that...
Despite the activation of T lymphocytes by antigen‐presenting cells being responsible for eliciting antigen‐specific immune responses, their crosstalking suffers from temporospatial limitations and endogenous influencing factors, which restrict the generation of a strong antitumor immunity. Here, cascade cell membrane coating is reported to prepare biomimetic nanoparticles (BNs) that can manipulate...
The eye converts an optical signal to an ionic signal. This transduction is mimicked here using a photodiode in contact with ionic conductors, such as hydrogels. Photons generate electron‐hole pairs in the photodiode. The photodiode/hydrogel interface forms capacitive coupling so that movements of electrons and holes in the photodiode induce movements of ions in the hydrogels. The hydrogels can be...
Melt electrowriting (MEW) is a high‐resolution additive manufacturing technology that places unique constraints on the processing of thermally degradable polymers. With a single nozzle, MEW operates at low throughput and in this study, medical‐grade poly(ε‐caprolactone) (PCL) is heated for 25 d at three different temperatures (75, 85, and 95 °C), collecting daily samples. There is an initial increase...
Hierarchical hollow structure with unique interfacial properties holds great potential for microwave absorption (MA). Ti3C2Tx MXene has been a hot topic due to rich interface structure, abundant defects, and functional groups. However, its overhigh permittivity and poor aggregation‐resistance limit the further application. Herein, a hierarchical MXene‐based hollow microsphere is prepared via a facile...
The regulation of perovskite crystallization and nanostructure have revolutionized the development of high‐performance perovskite solar cells (PSCs) in recent years. Yet the problem of stably passivating perovskite surface defects remains perplexing. The 1D perovskites possess superior physical properties compared with bulk crystals, such as excellent moisture stability, self‐healing property, and...
Lead halide perovskite nanocrystals (NCs) exhibit excellent optoelectronic performance, however, the broad application is limited by their poor stability. Herein, a strategy for stable core‐shell structured bismuth‐doped lead halide perovskite NCs is reported. The stable core‐shell perovskite NCs are prepared based on heterovalent substitutions and surface segregation effect. Core‐shell features are...
Long coherence lengths (CLs) of crystals and proper intermixed phase amount guarantee charge transport and exciton dissociate efficiently, which is crucial for organic solar cells (OSCs) to achieve high device performance. However, extending CLs usually reduces the intermixed phase, leading to an insufficient interface for exciton dissociation. Herein, a strategy using a binary polymer with different...
Slurries of semiconductor particles individually capable of unassisted light‐driven water‐splitting are modeled to have a promising path to low‐cost solar hydrogen generation, but they have had poor efficiencies. Tandem microparticle systems are a clear direction to pursue to increase efficiency. However, light absorption must be carefully managed in a tandem to prevent current mismatch in the subcells,...
Impaired white adipose tissue (WAT) function has been recognized as a critical early event in obesity‐driven disorders, but high buoyancy, fragility, and heterogeneity of primary adipocytes have largely prevented their use in drug discovery efforts highlighting the need for human stem cell‐based approaches. Here, human stem cells are utilized to derive metabolically functional 3D adipose tissue (iADIPO)...
Hybrid organic–inorganic piezoelectrics have attracted attention due to their simple synthesis, mechanical flexibility, and designability, which have promising application potential in flexible sensing and self‐powered energy harvesting devices. Although some hybrid piezoelectrics are discovered, most of their structures are limited by the perovskite‐type and often contain lead. Herein, the synthesis,...
Atomic force microscopy (AFM) is one of the most popular imaging and characterizing methods applicable to a wide range of nanoscale material systems. However, high‐resolution imaging using AFM generally suffers from a low scanning yield due to its method of raster scanning. Here, a systematic method of data acquisition and preparation combined with a deep‐learning‐based image super‐resolution, enabling...
Luminescent covalent organic frameworks (LCOFs) have attracted significant attention due to their tunability of structures and photophysical properties at molecular level. LCOFs are built to highly ordered and periodic 2D or 3D framework structures through covalently assembling with various luminophore building blocks. Recently, the advantages of LCOFs including predesigned properties of structure,...
Morre's law is coming to an end only if the memory industry can keep stuffing the devices with new functionality.
