Background The research field of advance care planning (ACP) for the surrogate decision makers of advanced cancer patients in China is still at the initial stage, and the relevant researches are fragmented and poorly targeted, lacking systematic analysis of the influencing factors. Objective To systematically review the influencing factors of ACP participation in surrogate decision makers of advanced cancer patients, so as to provide a reference for subsequent researches in this field. Methods This study was a mixed-methods systematic review. In April 2022, CNKI, Wanfang Data Knowledge Service Platform, PubMed, EmBase, the Cochrane Library, Web of Science, and CBM were searched by computer for the studies related to influencing factors of ACP participation in surrogate decision makers of advanced cancer patients from the inception to 2022-07-01. After evaluating the quality of literature and extracting information from the included studies, the method of JBI Hybrid System Evaluation Guide was used to integrate quantitative studies and qualitative studies after extracting data separately, and then the themes were summarized, obtaining the influencing factors of the final ACP participation in surrogate decision makers. Results A total of 11 papers were included after literature screening and evaluation of literature quality, including 5 qualitative studies and 6 cross-sectional studies. The final results were integrated into 4 categories of personal factors, external support, information access, and disease status, involving 22 influencing factors such as religious beliefs and clan culture, social network, ACP understanding, and disease development expectation after integrating the analysis results of quantitative and qualitative studies. Conclusion There are multiple influencing factors of ACP participation in surrogate decision makers of advanced cancer patients. Public perception, communication, policies and personal characteristics of surrogate decision makers can affect their ACP participation. Therefore, relevant education should be strengthened to improve public perception, an effective communication mechanism among patients, surrogate decision makers and health care providers should be established, the protection of relevant policies and regulations should be improved to strengthen guidance and intervention on variable factors.

All-inorganic CsPbX3 (X = Cl, Br or I) perovskite nanocrystals have attracted extensive interest recently due to their exceptional optoelectronic properties. In an effort to improve the charge separation and transfer following efficient exciton generation in such nanocrystals, novel functional nanocomposites were synthesized by the in situ growth of CsPbBr3 perovskite nanocrystals on two-dimensional MXene nanosheets. Efficient excited state charge transfer occurs between CsPbBr3 NCs and MXene nanosheets, as indicated by significant photoluminescence (PL) quenching and much shorter PL decay lifetimes compared with pure CsPbBr3 NCs. The as-obtained CsPbBr3/MXene nanocomposites demonstrated increased photocurrent generation in response to visible light and X-ray illumination, attesting to the potential application of these heterostructure nanocomposites for photoelectric detection. The efficient charge transfer also renders the CsPbBr3/MXene nanocomposite an active photocatalyst for the reduction of CO2 to CO and CH4. This work provides a guide for exploration of perovskite materials in next-generation optoelectronics, such as photoelectric detectors or photocatalyst.

Distributed generations can be divided into traditional synchronous generators and inverter interfaced distributed generations (IIDG) according to their different operation mode. While the fault characteristics of IIDG is different from traditional Distributed Generators, the in-depth analysis on output characteristics and fault characteristics of IIDG are the foundation of micro grid protection. The mathematical models under P/Q and V/F control strategy are discussed. After simplifying its model, the fault characteristics of IIDG under P/Q and V/F control strategy are studied using the simulation of PSCAD/EMTDC. The analysis on the fault characteristics of IIDG that lays the theoretical foundation for the micro-grid relay protection.
