Fractal evolution of lignite microstructure by biosurfactant treatment: Implications for pore-fracture network reconstruction

Xuan Liu, Xiang Fu, Lihui Dai, Xu Li

To explore the influence of biosurfactants on the microstructure fractal of low-rank coal, lignite was taken as the research object. Coal samples were treated with rhamnolipid solutions of different concentrations. Combined with multi-scale characterization techniques such as computed tomography (CT) three-dimensional reconstruction, …

Defective graphene synergizes with NiO x nanosheets to facilitate dual-defect-assisted two-electron oxygen reduction

Run Huang, Helong Wu, Qingchao Fang, Ying Chen et autres

One of the biggest challenges in the electrochemical synthesis of H2O2 is the development of high-performance and economical catalysts. In this work, a two-dimensional composite material consisting of NiOx nanosheets and defective graphene (DG) (NiOx@DG) was prepared and showed excellent electrocatalytic performance …

Federated Cross-Modal Retrieval with Missing Modalities via Semantic Routing and Adapter Personalization

Hefeng Zhou, Xuan Liu, Sicheng Chen, Wutong Zhang et autres

Federated cross-modal retrieval faces severe challenges from heterogeneous client data, particularly non-IID semantic distributions and missing modalities. Under such heterogeneity, a single global model is often insufficient to capture both shared cross-modal knowledge and client-specific characteristics. We propose RCSR, a personalization-friendly federated …
