Mechanically sensitive tissues (e.g., skeletal muscles) greatly need mechanical stimuli during the development and maturation. The extracellular matrix (ECM) mediates these signals through nonlinear viscoelasticity of collagen networks that are predominant components of the ECM. However, the interactions between cells and ECM form a feedback loop, and it has not yet been possible to determine the...
Bone mineralization is a ubiquitous process among vertebrates that involves a dynamic physical/chemical interplay between the organic and inorganic components of bone tissues. It is now well documented that carbonated apatite, an inorganic component of bone, is proceeded through transient amorphous mineral precursors that transforms into the crystalline mineral phase. Here, the evolution on mineral...
Mineral Precursors
A fantastic journey of the mineral precursors involved in bone biomineralization involves the formation, storage, and transport of intracellular mineral precursors and the transfer of intracellular minerals to their designated sites. Cellular activities, biomolecules and metabolic processes synergistically control the formation and crystallization of mineral precursors during mineralization,...
The uncontrollable growth and uneven nucleation of lithium metal can be addressed by utilizing spatial confinement structures in conjunction with lithiophilic sites. However, their complex fabrication technique and the inhomogeneous dispersion of lithiophilic sites make the application ineffective. In this work, ultra‐uniformly dispersed SiOx seeds and defects are produced in situ to achieve the spatially...
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...
Because of its high specific capacity, the silicon–graphite composite (SGC) is regarded as a promising anode for new‐generation lithium‐ion batteries. However, the frequently employed two‐section preparation process, including the modification of silicon seed and followed mixture with graphite, cannot ensure the uniform dispersion of silicon in the graphite matrix, resulting in a stress concentration...
Atomically dispersed metal catalysts often exhibit high catalytic performances, but the metal loading density must be kept low to avoid the formation of metal nanoparticles, making it difficult to improve the overall activity. Diverse strategies based on creating more anchoring sites (ASs) have been adopted to elevate the loading density. One problem of such traditional methods is that the single...
Single‐Atom Catalysts
The low loading of single‐atom catalysts makes it difficult to improve their overall activity. In article number 2200073, Ang Li, Erjun Kan, Li Song, Jinlong Gong, and co‐workers report a chemical scissors strategy to saturate the anchoring sites for single atoms, which elevates the loading of Pd single atoms even on bare substrate with only a few anchoring sites.
Fast charging rate and large energy storage are key requirements for lithium‐ion batteries (LIBs) in electric vehicles. Developing electrode materials with high volumetric and gravimetric capacity that could be operated at a high rate is the most challenging problem. In this work, a general multi‐interface strategy toward densified carbon materials with enhanced comprehensive electrochemical performance...
Polyhedral oligomeric silsesquioxane (POSS) is a family of organic/inorganic hybrid materials with specific molecular symmetry, and shows great potential in the structural design of nanomaterials. Here, a “bottom‐up” strategy is designed to fabricate 3D interconnected Si/SiOx/C nanorings (NRs) via AlCl3‐assisted aluminothermic reduction using dodecaphenyl cage silsesquioxane (T12‐Ph) as the building...
Photo‐electronic devices based on reactive oxygen species (ROS) generation suffer a crucial limitation in wound treatment due to their sandwich structure, which prevents the contact of ROS with wound tissue. In this work, the first anti‐sandwich structured visible‐light/electricity dual‐responsive wound dressing is constructed for treatment of methicillin‐resistant Staphylococcus aureus (MRSA), based...
Metal−organic frameworks (MOFs) and their derivatives have attracted enormous attention in the field of energy storage, due to their high specific surface area, tunable structure, highly ordered pores, and uniform metal sites. Compared with the wide research of MOFs and their related materials on anode materials for alkali metal ion batteries, few works are on cathode materials. In this review, design...
Hepatocellular carcinoma (HCC) is the third leading cause of cancer‐related death worldwide. The prognosis of HCC remains very poor; thus, an effective treatment remains urgent. Herein, a type of nanomedicine is developed by conjugating Fe@Fe3O4 nanoparticles with ginsenoside Rg3 (NpRg3), which achieves an excellent coupling effect. In the dimethylnitrosamine‐induced HCC model, NpRg3 application significantly...
The future electronic application of graphene highly relies on the production of large‐area high‐quality single‐crystal graphene. However, the growth of single‐crystal graphene on different substrates via either single nucleation or seamless stitching is carried out at a temperature of 1000 °C or higher. The usage of this high temperature generates a variety of problems, including complexity of operation,...
Single‐crystal graphene wafers (SCGWs) are an essential requirement for graphene's scalable utilization in electronics' circuits. In article number 1805395, Xiaoming Xie and co‐workers grow high quality 6 in. SCGWs by chemical vapor deposition on a unique (111) Cu85Ni15 substrate at 750 °C, taking advantage of the ultra‐flat single crystalline Cu/Ni substrate and nickel's high catalytic power.
The electrochemical reduction of carbon dioxide (CO2) is an emerging route for curbing excessive CO2 emissions and producing add‐valued chemicals.

The synergic effects of Cu85Ni15 and the copper vapor evaporated from copper foil enabled the fast growth of a ≈300 μm bilayer graphene in ≈10 minutes. The copper vapor reduces the growth rate of the first graphene layer while the carbon dissolved in the alloy boosts the growth of the subsequently developed second graphene layer with an AB‐stacking order.
