All‐solid‐state batteries (ASSBs) represent a highly promising next‐generation energy storage technology owing to their inherently high safety, device reliability, and potential for achieving high energy density in the post‐ara of lithium‐ion batteries, and therefore extensive searches are ongoing for ideal solid‐state electrolytes (SSEs). Though promising, there is still a huge barrier that limits...
Organic luminescent materials are indispensable in optoelectronic displays and solid‐state luminescence applications. Compared with single‐component, multi‐component crystalline materials can improve optoelectronic characteristics. This work forms a series of full‐spectrum tunable luminescent charge‐transfer (CT) cocrystals ranging from 400 to 800 nm through intermolecular collaborative self‐assembly...
Covalent organic frameworks (COFs) with precisely controllable structures and highly ordered porosity possess great potential as electrocatalysts for hydrogen evolution reaction (HER). However, the catalytic performance of pristine COFs is limited by the poor active sites and low electron transfer. Herein, to address these issues, the conductive carbon nanotubes (CNTs) are coated by a defined structure...
Magnetic iron oxide nanoparticles (MIONs) based T2‐weighted magnetic resonance imaging (MRI) contrast agents (CAs) are liver‐specific with good biocompatibility, but have been withdrawn from the market and replaced with Eovist (Gd‐EOB‐DTPA) due to their inherent limitations (e.g., susceptibility to artifacts, high magnetic moment, dark signals, long processing time of T2 imaging, and long waiting...
The detection of biomolecules at the single molecule level has important applications in the fields of biosensing and biomedical diagnosis. The solid‐state nanopore (SS nanopore) is a sensitive tool for detecting single molecules because of its unique label‐free and low sample consumption properties. SS nanopore translocation of small biomolecules is typically driven by an electronic field force and...
Stretchable wearable thermoelectric (TE) generators (WTEGs) without compromising output performance for real wearables have attracted much attention recently. Herein, a 3D thermoelectric generator with biaxial stretchability is constructed on the device level. Ultraflexible inorganic Ag/Ag2Se strips are sewn into the soft purl‐knit fabric, in which the thermoelectric legs are aligned in the direction...
PbYb0.5Nb0.5O3 (PYN)‐based ceramics, featured by their ultra‐high phase‐switching field and low sintering temperature (950 °C), are of great potential in exploiting dielectric ceramics with high energy storage density and low preparation cost. However, due to insufficient breakdown strength (BDS), their complete polarization‐electric field (P‐E) loops are difficult to be obtained. Here, to fully reveal...
Constructing active heterointerfaces is powerful to enhance the electrochemical performances of transition metal dichalcogenides, but the interface density regulation remains a huge challenge. Herein, MoO2/MoS2 heterogeneous nanorods are encapsulated in nitrogen and sulfur co‐doped carbon matrix (MoO2/MoS2@NSC) by controllable sulfidation. MoO2 and MoS2 are coupled intimately at atomic level, forming...
Nanocomposite films hold great promise for multifunctional devices by integrating different functionalities within a single film. The microstructure of the precipitate/secondary phase is an essential element in designing composites’ properties. The interphase strain between the matrix and secondary phase is responsible for strain‐mediated functionalities, such as magnetoelectric coupling and ferroelectricity...
Anti‐icing coatings on outdoor infrastructures and transportations inevitably suffer from surface injuries, especially in extreme weather events (e.g., freezing weather or acid rain). The coating surface damage can result in anti‐icing performance loss or even icing promotion. The development of anti‐icing coatings that enables self‐healing in extreme conditions is highly desired but still challenging...
Early Diagnosis of Cancers
In article 2205445, Shangquan Wu, Qingchuan Zhang, and co‐workers develop an ultra‐sensitive nanomechanical sensor, which uses a magnetic‐driven microcantilever array to selectively detect oncogenic exosomes. The magnetic force produces a far greater deflection of microcantilever than that produced by the intermolecular interaction force, even in the presence of very low...
Exosomes are a class of nanoscale vesicles secreted by cells, which contain abundant information closely related to parental cells. The ultrasensitive detection of cancer‐derived exosomes is highly significant for early non‐invasive diagnosis of cancer. Here, an ultrasensitive nanomechanical sensor is reported, which uses a magnetic‐driven microcantilever array to selectively detect oncogenic exosomes...
The organic–inorganic halide perovskite solar cell (PerSC) is the state‐of‐the‐art emerging photovoltaic technology. However, the environmental water/moisture and temperature‐induced intrinsic degradation and phase transition of perovskite greatly retard the commercialization process. Herein, a dual‐functional organic ligand, 4,7‐bis((4‐vinylbenzyl)oxy)‐1,10‐phenanthroline (namely, C1), with crosslinkable...

Activation of the phagocytosis of macrophages to tumor cells is an attractive strategy for cancer immunotherapy, but the effectiveness is limited by the fact that many tumor cells express an increased level of anti‐phagocytic signals (e.g., CD47 molecules) on their surface. To promote phagocytosis of macrophages, a pro‐phagocytic nanoparticle (SNPACALR&aCD47) that concurrently carries CD47 antibody...

Van der Waals epitaxy (vdWE) is crucial for heteroepitaxy of covalence‐bonded semiconductors on 2D layered materials because it is not subject to strict substrate requirements and the epitaxial materials can be transferred onto various substrates. However, planar film growth in covalence‐bonded semiconductors remains a critical challenge of vdWE because of the extremely low surface energy of 2D materials...
