This work will promote the technological development of Mn and Fe based flexible asymmetric supercapacitors, promote their application in wearable electronic devices and implantable medical electronic devices, and help these flexible electronic devices reduce energy loss and improve device energy efficiency。

In this work, a vacuum sampling tube (VT) assisted hollow microne array (MAP) interstitial-fluid (ISF) sampling device was designed. Using the micro negative pressure generated by VT to drive the 3D printed dual-channel hollow MAP, 18 samples were obtained in vivo within 5 minutes.42 µL ISF extraction, leading extraction performance。

In this paper, pure phase manganese boride (MnBx) materials with different Mn atomic coordination numbers such as Mn2B, MnB, MnB2 and MnB4 have been synthesized successfully。Through the structural characterization and performance comparison of these materials, the research group found that with the increase of B content in the compound, the catalytic activity of a single Mn catalytic site was greatly improved。在−0.At 3 V, the optimal FE and ammonia yield of MnB4 reached 38, respectively.5 ± 2.7%和74.9 ± 2.1 μg h−1 Mgcat −1, much higher than the boride materials reported so far...

In this work, we propose a novel cross-perspective geopositioning method, which aligns the geometric spatial layout between cross-perspective images through feature recombination, reduces the ambiguity caused by geometric misalignment, and makes the discriminative positioning clues easier to learn。In addition, we introduce weighted (B+1) tuple losses and show that it significantly speeds up training and improves performance。Numerous experiments show that the method achieves state-of-the-art performance on CVUSA, CVACT, and VIGOR data sets....

Through comprehensive analysis, the team confirmed the existence of multiple discrete layers inside the lunar soil。Combined with the geological background of the Chang 'e-3 landing area and the formation principle of impact craters, it is speculated that these discrete layers may be derived from multiple deposits of sputtering materials from the surrounding small impact craters。
