摘要：Photoelectrocatalytic water splitting is an effective way to utilize the solar energy to solve the energy shortage. The valence band edge of WO3 located at 3V vs. normal hydrogen electrode（NHE）, which can offer enough potential to kinetically oxidize water for oxygen evolution reaction. However, water oxidation reaction kinetics is sluggish when only WO3 is used as the photoanode. It is highly desirable to use cocatalyst to promote the kinetics. Mn Oxloaded on the WO3 photoanode through photodeposition methods improves the photoelectrochemical water oxidation performance. A maximum photocurrent density of composite photoanode is achieved with a deposition time of 3 min, which is higher than that of pristine WO3 photoanode around 40%. Mn O2 is not only a cocatalyst for water splitting but also for improving oxidation selectivity. We tried to use two means to load Mn Oxon WO3 photoanode material. It is observed that loading a moderate amount of Mn Oxon the WO3 by photodeposition can promote the performance of the WO3 photoanode.

摘要：目的对心血管手术患者术中获得性压力性损伤风险预测工具进行范围综述,为临床实践和未来预测工具的优化和开发提供参考。方法检索PubMed、Embase、Cochrane Library、Web of Science核心合集、中国知网、万方数据服务平台、维普中文科技期刊数据库、中国生物医学文献数据库中有关心血管手术患者术中获得性压力性损伤风险预测工具的研究,检索时限为建库至2023年12月1日。由2名研究者独立筛选文献和提取数据。采用预测模型偏倚风险评价工具及诊断准确性研究质量评价工具2对纳入文献进行偏倚风险及适用性评价。结果共纳入16篇文献,涉及11个预测模型和7种筛查量表。模型构建方法多样,预测性能总体较好,手术时间、体外循环时间、年龄、术中体温、糖尿病史是模型中出现频次最高的预测因子。筛查量表预测性能较预测模型差,区分度均在0.7以下。结论目前心血管手术患者术中获得性压力性损伤风险预测工具的预测效能中等,风险预测模型的预测效能优于筛查量表,但纳入文献偏倚风险较高。临床护理人员应关注心血管手术患者术中获得性压力性损伤的高危因素,完善、更新现有工具,或在多中心大样本、前瞻性设计基础上,借助人工智能,构建预测性能佳、可操作性强的低偏倚高适用的预测工具。
