Carbon dioxide photocatalytic reduction (CO2-PR) is an efficient method for controlling CO2emissions and generating cleaner energy while mitigating global warming. Tungsten oxides (WxOy) have attracted considerable attention for CO2-PR due to their excellent spectral absorbance. However, comprehensive reviews are lacking on the use of WxOyfor CO2-PR. Therefore, this review provides a detailed summary of t research progress made with WxOy-based catalysts in CO2-PR. It also explains the fundamental principles of CO2-PR and evaluates key performance indicators that affect the activity of WxOy-based photocatalysts,including yield, selectivity, stability, and apparent quantum yield. Additionally, this review explores opportunities for synthesizing high-performance WxOy-based photocatalysts and highlights their potential for the green preparation of C1/C2 products through CO2-PR. These innovative strategies aim to address the challenges and pressures associated with energy and environmental issues, particularly by enhancing artificial photosynthesis efficiency.

Chiral coordination molecular cages/capsules with discrete nanoconfined chiral cavities demonstrate significant potential applications across various fields. In this study, we utilized Tr?ger's base as the building block to design and synthesize two pairs of enantiopure ligands. These ligands were then self-assembled with Pd(II) ions through chiral self-sorting coordination, resulting in the formation of two pairs of homochiral M2L4-type coordination molecular capsules. Notably, due to differences in the substitution positions on the Tr?ger's base, these two pairs of enantiomeric coordination molecular capsules exhibited distinct levels of cavity closures, cavity sizes, and host-guest recognition properties. This research offers valuable insights into the construction of novel chiral molecular capsules and the regulation of confined cavities.

The electrowetting triple-liquid lens has excellent zoom performance, but its structural complexity and design difficulty are relatively high. Therefore, we propose a method for optimizing the structural parameters of the electrowetting triple-liquid lens based on joint simulation. To design a triple-liquid lens, Comsol and Zemax software are used to establish triple-liquid lens simulation models under different structural parameters, and its focal lengths under different voltages are obtained. The effects of height and taper on zoom range and initial focal length are analyzed, and a set of structural parameters with the maximum zoom range and the longest initial focal length is determined. To verify the method’s reliability, we prepare the triple-liquid lens models with different heights and tapers, and conduct zoom experiments. The simulation and experimental results show that the initial focal length of the triple-liquid lens correlates positively with height and taper;the zoom range correlates positively with taper, but height is the main influencing factor. When the height is 12 mm and the taper is 20°, the lens has the most extensive zoom range and the longest initial focal length. When the taper is less than 15°, the simulation and experimental results are highly consistent. © 2025 Editorial Office of Chinese Optics. All rights reserved.

学术志趣是博士生潜心学术、琢磨学问的动力之源,是博士生持续深耕学术研究、维持学术信仰与学科情怀的关键所在。通过扎根理论分析方法,对访谈资料和网络资料进行分析发现,博士生学术志趣消退是一个心理和行为相互叠加的动态过程,历经学术动力消退、心理压力、价值冲突等心理后,逐渐成为“学术空壳”。这些心理感知逐渐转化为外部行为倾向,表现为消极定势和现实逃离,最终生成“学术过客”形象。这一症候背后既与博士生的认知行为偏向直接关联,也是功绩主义社会结构下学术异化的结果。鉴于此,“他助”与“自渡”协力是纾解博士生学术志趣消退之困的关键,需要多方力量共同努力。
