Exploring highly efficient, portable, and robust biocatalysts is a great challenge in colorimetric biosensors. To overcome the challenging states in creating single‐atom biocatalysts, such as insufficient activity and stability, here, this work has engineered a unique CeO2 support as nanoglue to tightly anchor the Ru single‐atom sites (CeO2‐Ru) with strong electronic coupling for achieving highly...
To obtain anode materials with high capacity/energy density for lithium‐ion batteries, a polyanionic compound Li2FeGeO4 is prepared, which combines the conversion‐type Fe‐based oxide and the alloy‐type Ge‐based oxide at the atomic scale. The influence of citric acid in the sol–gel process on the structure and performance of the calcined products (LFG0, LFG1, and LFG2) is investigated. The results...
Vascular Electrical Stimulations
Hong Li, Liming Yang, and co‐workers used battery‐free implants and surgically mounted them on the abdominal aorta of high‐fat‐fed ApoE‐/‐ mice, which were electrically stimulated using a wireless electrical stimulation device for four weeks to observe changes in atherosclerotic plaques. Direct vascular electrical stimulation has emerged as a promising therapeutic...
Electrical stimulation (ES) is a safe and effective procedure in clinical rehabilitation with few adverse effects. However, studies on ES for atherosclerosis (AS) are scarce because ES does not provide a long‐term intervention for chronic disease processes. Battery‐free implants and surgically mounted them in the abdominal aorta of high‐fat‐fed Apolipoprotein E (ApoE−/−) mice are used, which are electrically...
2D materials with low symmetry are explored in recent years because of their anisotropic advantage in polarization‐sensitive photodetection. Herein the controllably grown hexagonal magnetic semiconducting α‐MnTe nanoribbons are reported with a highly anisotropic (100) surface and their high sensitivity to polarization in a broadband photodetection, whereas the hexagonal structure is highly symmetric...
Here, the synthesis of a series of pure phase metal borides is reported, including WB, CoB, WCoB, and W2CoB2, and their surface reconstruction is studied under the electrochemical activation in alkaline solution. A cyclic voltammetric activation is found to enhance the activity of the CoB and W2CoB2 precatalysts due to the transformation of their surfaces into the amorphous CoOOH layer with a thickness...
Transition metal borides are considered as promising electrocatalysts for water splitting due to their metallic conductivity and good durability. However, the currently reported monometallic and noncrystalline multimetallic borides only show generic and monofunctional catalytic activity. In this work, the authors design and successfully synthesize highly crystalline ternary borides, Mo2NiB2, via a...
