硫酸亚铁制备实验的课程思政设计

硫酸亚铁的制备是典型的无机制备实验。按绿色化学的要求对实验方法进行改进,将废弃Fe资源综合利用,合成可用于抗贫血药物的重要原料硫酸亚铁,并按照药典的标准进行分析检测。学生强化了称量、除杂、加热、溶解、蒸发、结晶以及固液分离等实验基本技能,认识了Fe等废弃资源综合利用的重要性,进一步明了Fe的性质与生命健康之间的关系,体会化学在改善环境、促进人类健康和社会发展中的重要作用,增强了专业自信心和自豪感,对学生能力培养和素质发展具有良好的促进作用。

Highly diversified Zika viruses imported to China, 2016

Dear Editor, First discovered during 1947 in Uganda from febrile rhesus macaques, Zika virus （ZIKV） is a mosquito-borne, reemerging flavivirus historically known to be present in much of Africa and Asia, occasionally causing outbreaks amongst the local populace （Haddow et al., 2012）. ZIKV infections in humans are mostly asymptomatic, but a small percentage of patients may show clinical symptoms such as a fever and rash, which resolve within a week or less.
