The current status of study on the silica/gold nanoshells is reviewed in this paper, meanwhile, the preparing methods and the important applications in nanomedicine of the silica/gold nanoshells are elucidated in de.
氧化硅/金纳米壳层因具有由其核/壳相对尺寸所决定的特殊光学性能和良好的生物相容性,所以在纳米医学等许多领域得到了广泛的重视。
The grade oflow-grade complexgold oxide ores are less than3g/t,this kind ofores are fitforleachingonly.
低品位复杂氧化金矿 ,因其品位<3g/t,只适合“堆浸”生产 ,而堆浸过程中主要需解决其氰化率低的关键问题 ,本试验为了提高其氰化率而采用试剂预处理 ,使氰化率提高到83 %~91%。
A commercially economic process is obtained for preparation of p-Methylcatechol and p-Methylcatechol dimethylacetate from P-Cresol by acetylization, Freis rearrangement, Dakin H D oxidation and etherification.
