Professor Liu Fude's team: Reel-to-reel preparation of multistage Lipophilic structure fluid collection to greatly improve the circulation of lithium metal batteries...
2024-04-12In this study, a 3D collector with multistage Lipophilic structure was prepared by combining the roll-to-roll process and solution combustion method。The preparation method has the advantages of simple and low cost, and is easy to be industrialized on a large scale。Using the fluid collector as the substrate of lithium metal in the lithium metal battery, the deposition mode of lithium metal can be changed from top-down to bottom-up during the cycle of the battery, so as to greatly improve its cycle stability and safety。

AIJ 2023 | Recommended Privacy Protection Graph Convolutional Network for federal Articles
2024-04-10This work proposes a federal recommendation framework based on graph convolutional network, designs a novel privacy protection graph convolution method based on security aggregation, uses item-based user representation to compensate for the loss of recommendation effect caused by protecting user privacy, and improves the group hiding strategy to protect user privacy。This method can make use of graph higher-order connection information which is difficult to be utilized by existing methods, and it is superior to all existing federated methods in the problem studied。

Researcher CAI Xingke's research team confirmed the coordination number pairs in a research paper published in Advanced Materials, a nature index journal...
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...

AAAI 2024 | Align geometric spatial layouts in cross-perspective geolocation by feature recombination
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....

Ding Chunyu's team published a research paper in IEEE Transactions on Geoscience and Remote Sensing...
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。
