A phase-selective,bis-urea organogelator with a curved bis-naphthalene core was synthesized and characterized.This gelator is capable of gelating a variety of hydrocarbons and oils.The resulting gels have been characterized by rheology,SEM,and molecular modelling.The gelator can be applied in the powder form for the recovery of a thin layer of petrol oil spill in water.

急性妊娠脂肪肝(acute fatty liver of pregnancy,AFLP)是一种非常少见的妊娠期并发症,它发病骤急,病情凶险,国外报道的AFLP发病率为1/6692~1/13 328[1],国内尚无确切的文献报道.但已证实AFLP对孕妇和胎儿的围产结局有致命的影响,若处理不及时很可能造成母婴死亡.为了提高对AFLP发病特点的认识,探讨如何进行早期诊断和治疗,我们对收治的AFLP患者的

亲眼看到金箔贴饰的古代服装实物,这一刻让人目眩。大约三年前,中国历史博物馆的一次大型展览上,新疆尉犁县营盘十五号墓男性墓主的一身殓服完整地亮相,其上点点闪耀的金箔,使很多人都猝然遭遇了目眩的时刻。墓主淡黄绢袍的前胸装饰用小片金箔贴出穹形纹样;足上的绢袜,也饰以金箔贴成的花纹,昔日的高贵与荣耀,就在点点金光中沉默地凯旋,一下逼近到我们面前。 实际上,在新疆尉犁县营盘古墓群的其他墓葬中,同样出土有金
