Research on the Chinese capital culture perception based on Weibo big data.

Ancient capital culture, red culture, Beijing-style culture, and innovation culture together constitute the capital's cultural system of China and support Beijing's position as the Chinese cultural center. In order to better help the cultural construction of the capital, Beijing, and to find some common and reasonable ways to reconcile the complex urban cultural system, this paper is based on the Weibo data of Beijing in 2019, takes the BERT pre-training model and the newer topic model "BERTopic" as the tools, combines the text content, spatial layout, and sentiment analysis methods, and explores the public perception of four types of capital culture in Beijing. The results reveal that: (1) Although the perception level of Dongcheng, Xicheng, Haidian and Chaoyang core areas is much higher than that of remote areas, the sentiment feedback of remote areas is better than that of the former; (2) A type of culture actively introduces other cultural types or even foreign cultural elements in the system, which helps it form a unique cultural attraction.

Design of Ti-Pt Co-doped α-FeO photoanodes for enhanced performance of photoelectrochemical water splitting.

This study demonstrates Ti and Pt co-doping can synergistically improve the PEC performance of the α-FeO photoanode. By varying the doping methods, the sample with in-situ Ti ex-situ Pt doping (Ti-Pt) exhibits the best performance. It demonstrates that Ti doping in bulk facilities charge separation and Pt doping on the surface further accelerates charge transfer.
