Based on the network attention data of Douyin's fans, this article analyzes the spatial heterogeneity and driving factors of network attention to 5A-level tourist attractions in China using rank-size, kernel density, and nearest neighbor index. The results show that: (1) From the perspective of...

The J-TEXT Tokamak device has the operation ability of the high field side horizontal divertor configuration. Under this divertor configuration, plasma equilibrium is unstable in the horizontal direction. This work studies the performance of the horizontal displacement control system to the...

Construction of S-scheme heterojunctions has been regarded as an appealing strategy to explore efficient photocatalysts for artificial photosynthesis. Herein, a unique 0D/1D S-scheme heterojunction of CsPbBr3/AgBr (CPB/AgBr) was developed by assembling CsPbBr3 nanocrystals (NCs) onto AgBr...

The pure and 2 mol% Ce 3+ ions doped KY 3 F 10 (Ce: KYF) single crystals were successfully grown in a vacuum by spontaneous nucleation of the vertical Bridgman method. Ce: KYF single crystal had high crystalline quality and transmittance, and the cutoff absorption edge was significantly red...
