通过问卷星软件对新冠肺炎疫情期间SN市公安局在岗民警(男性)进行电子问卷调查,结合数据挖掘和Logistic回归构建民警心理健康风险评估模型和风险评分表,调查结果显示:相对于派出所、监管类和交管类民警群体,市局综合、分局综合和巡特警类民警群体在面对此次新冠肺炎疫情突发公共卫生事件时,他们的应对资源和心理储备相对不足,产生的负性心理情绪相对较多。利用Logistic回归模型构建的突发公共卫生事件下民警心理健康风险评估模型的诊断价值较高;依据该模型建立的评估问卷减轻了民警的填写压力,可以在短时间内高效率地对民警进行心理健康风险评估。

Electrocatalysis is a key technology for the new energy era and sustainable development, serving as the interface for interconversion of electrical and chemical energies, which spans a wide spectrum of applications in sustainable energy and environmental engineering. Electrocatalytic reactions including electrochemical CO2reduction reaction （eCO2RR）, hydrogen evolution reaction （HER）, and oxygen evolution/reduction reactions （OER/ORR）, hold essential promise for renewable energy technologies as well as complement the biogeochemical carbon and oxygen cycles.

A photocatalytic process was developed for intermolecular reductive coupling of aliphatic ketones with alkynes/alkenes to furnish tertiary alcohols. Mechanistic studies support that boron carbonitrides(BCN) promote the single electron reduction of unactivated aliphatic ketones to generate ketyl radicals with visible light irradiation, which then react with alkynes and alkenes to afford the allylic and aliphatic alcohols, respectively. The heterogeneous photocatalytic system is compatible with diverse substrates including pharmaceutical-related molecules(43 examples) with reusability and scale-up experiments, verifying the complementary synthetic utility of this method to the homogeneous catalysts.
