VO2 material, as a promising intercalation host, is widely investigated not only in aqueous lithium‐ion batteries, but also in aqueous zinc‐ion batteries (AZIBs) owing to its stable tunnel‐like framework and multivalence of vanadium. Different from lithium‐ion storage, VO2 can provide higher capacity when storing zinc ions, even exceeding its theoretical capacity (323 mAh g−1), but the specific reason...
Although the research on aqueous batteries employing metal as the anode is still mainly focused on the aqueous zinc‐ion battery, aqueous iron‐ion batteries are considered as promising aqueous batteries owing to the lower cost, higher specific capacity, and better stability. However, the sluggish Fe2+ (de)intercalation leads to unsatisfactory specific capacity and poor electrochemical stability, which...
Regulating electronic structures of the active site by manipulating the local coordination is one of the advantageous means to improve photocatalytic hydrogen evolution (PHE) kinetics. Herein, the ZnIn2S4/Mo2TiC2 Schottky junctions are designed to be constructed through the interfacial local coordination of In3+ with the electronegative O terminal group on Mo2TiC2 based on the different work functions...
Benefiting from the proton's small size and ultrahigh mobility in water, aqueous proton batteries are regarded as an attractive candidate for high‐power and ultralow‐temperature energy storage devices. Herein, a new‐type C4N polymer with uniform micropores and a large specific surface area is prepared by sulfuric acid‐catalyzed ketone amine condensation reaction and employed as the electrode of proton...
Micromachines with high environmental adaptability have the potential to deliver targeted drugs in complex biological networks, such as digestive, neural, and vascular networks. However, the low processing efficiency and single processing material of current 4D printing methods often limit the development and application of shape‐morphing micromachines (SMMs). Here, two 4D printing strategies are...
Aqueous zinc‐ion batteries (ZIBs) have been extensively studied due to their inherent safety and high energy density for large‐scale energy storage. However, the practical application is significantly limited by the growing Zn dendrites on metallic Zn anode during cycling. Herein, an environmental biomolecular electrolyte additive, fibroin (FI), is proposed to guide the homogeneous Zn deposition and...
Atherosclerosis Treatment
Herb derived drugs modulate gut microbiome homeostasis and gut‐generated bio‐metabolites. In article number 2105021, Jian‐Dong Jiang, Yongsheng Che, Lu‐Lu Wang, and co‐workers modify the immune cell dynamics and liver function using herb‐derived bicyclol, leading to improved chronic inflammation and cholesterol metabolism. The endothelial activation and cholesterol ester...
Atherosclerosis (AS) is associated with high morbidity and mortality, thus imposing a growing burden on modern society. Herb‐derived bicyclol (BIC) is a versatile bioactive compound that can be used to treat AS. However, its efficacy in AS is not yet described. Here, it is shown that BIC normalizes gut microflora dysbiosis induced by a high fat diet in Apoe(−/−) mice. Metagenome‐wide association study...
Light‐ignited combustions have been proposed for a variety of industrial and scientific applications. They suffer, however, from ultrahigh light ignition thresholds and poor self‐propagating combustion of typical high‐energy density materials, e.g., 2,4,6,8,10,12‐(hexanitrohexaaza)cyclododecane (CL‐20). Here, reported is that both light ignition and combustion performance of CL‐20 are greatly enhanced...
In article number 1900338, Guangcheng Yang and co‐workers provide a direction to achieve high performance light‐ignited combustions by formulating composite energetic materials. A novel relay‐domino‐like combustion reaction in a graphene oxide/2,4,6,8,10,12‐(hexanitrohexaaza) cyclododecane (GO/CL‐20) composite can be ignited by an infrared laser pulse in the order of ten‐milliseconds. A synergistic...
