冷冻电镜Cryo-EM)测试

测试样例

1)    冷冻电镜研究示意图 2)    冷冻电镜研究离子锂离子电池锂枝晶和SEI层的原子尺度解析 2)    冷冻电镜研究钙钛矿太阳能电池 2)    冷冻电镜研究生物物质结构

面向学科

化学、材料等相关学科

样品要求

1)    磁性样品指:Fe,Co,Ni元素或者磁铁可以有响应的材料 2)    低熔点、易分解、磁性、毒性、放射性的样品不可测 3)    载网:粉末样品需要使用进口超薄碳膜、进口超薄微栅、进口超薄金膜(含铜的样品,且需要做EDS或EELS测试)、国产标记微栅(需要检测特定的颗粒)。 4)    样品分散:用户需要把样品研磨后,滴到载网上,研磨方法是加入酒精后,在研钵中湿磨,研磨分散效果比超声分散效果要好一些,要想分散得好,可以适当延长研磨时间。 5)    制样浓度:特别强调,样品制样浓度要高一些,以在载网周围能看到一圈黑的(如果样品是黑的)样品为宜。 6)    样品烘干:测试之前,需要在加热板、红外灯或烘箱中干燥,温度设定根据样品不同而不同,一般为100度左右就可以,石墨烯样品可以设到180度,烘烤时间1个小时以上。 7)    其它样品制样:用户可以使用FIB、电解双喷、手工等方法制备样品。     特别提醒:因球差电镜特殊要求,所有球差电镜样品均需在普通透射电镜上检测不积碳后方可测试。
