To achieve high‐performance solid‐state lithium‐metal batteries (SSLMBs), solid electrolytes with high ionic conductivity, high oxidative stability, and high mechanical strength are necessary. However, balancing these characteristics remains dramatically challenging and is still not well addressed. Herein, a simple yet effective design strategy is presented for the development of high‐performance...
Engineered Extracellular Vesicles
Extracellular vesicles (EVs)‐based tumor immunotherapy has usually suffered from the limited cross presentation of tumor‐associated antigen by dendritic cells (DCs). In article number 2303541, Jun Hu, Xiangliang Yang, and co‐workers propose a straightforward engineering strategy to construct heat shock proteins 70 (HSP70) highly expressed EVs, which could capture...
Extracellular vesicles (EVs) have emerged as potential tools for tumor‐target therapy accompanied with activating anticancer immune responses by serving as an integrated platform, but usually suffered from the limited cross presentation of tumor‐associated antigen by dendritic cells (DCs). Here, a straightforward engineering strategy to construct heat shock proteins 70 (HSP70) highly expressed EVs...
Photocatalytic oxygen reduction reaction (ORR) for H2O2 production in the absence of sacrificing agents is a green approach and of great significance, where the design of photocatalysts with high performance is the central task. Herein, a spatial specific S‐scheme heterojunction design by introducing a novel semiconducting pair with a S‐scheme mechanism in a purpose‐designed Janus core–shell‐structured...
Covalent organic frameworks (COFs) have emerged as a new class of cathode materials for energy storage in recent years. However, they are limited to two‐dimensional (2D) or three‐dimensional (3D) framework structures. Herein, this work reports designed synthesis of a redox‐active one‐dimensional (1D) COF and its composites with 1D carbon nanotubes (CNTs) via in situ growth. Used as cathode materials...
Natural polymer‐based sutures have attractive cytocompatibility and degradability in surgical operations. Herein, anionic cellulose nanofibrils (ACNF) and cationic guar gum (CGG) are employed to produce nontoxic CGG/ACNF composite filament with a unique core–shell structure via interfacial polyelectrolyte complexation (IPC) spinning. The comprehensive characterization and application performance of...
Power generation by converting energy from the ambient environment has been considered a promising strategy for developing decentralized electrification systems to complement the electricity supply for daily use. Wet gases, such as water evaporation or moisture in the atmosphere, can be utilized as a tremendous source of electricity by emerging power generation devices, that is, moisture‐enabled‐electric...
Tissue Regeneration
In article number 2202485, Na Ren, Chao Liu, Hong Liu, and co‐workers report stem cell membrane‐encapsulated zeolitic imidazolate framework‐8 and take advantage of the innate targeting capacity towards stem cells to regulate osteogenic differentiation, and further promote bone repair.
Mesenchymal stem cells (MSCs) have been recognized as one of the most promising pharmaceutical multipotent cells, and a key step for their wide application is to safely and efficiently regulate their activities. Various methods have been proposed to regulate the directional differentiation of MSCs during tissue regeneration, such as nanoparticles and metal ions. Herein, nanoscale zeolitic imidazolate...
A noninvasive, easy operation, and accurate diagnostic protocol is highly demanded to assess systemic lupus erythematosus (SLE) activity during pregnancy, promising real‐time activity monitoring during the whole gestational period to reduce adverse pregnancy outcomes. Here, machine learning of serum metabolic fingerprints (SMFs) is developed to assess the SLE activity for pregnant women. The SMFs...
Polyetheretherketone (PEEK) is widely used in orthopedic and craniomaxillofacial surgeries as it exhibits excellent biocompatibility, mechanical property, and chemical stability. However, its clinical application is limited by the biological inertness of PEEK. Numerous efforts have been made to improve the bioactivity of this polymer over the years. However, modification methods that can not only...
