The results of studying the nanomorphology of thin films on the faces of quartz rhomboherons from the Sinilga ore occurrence (Subpolar Urals, Russia) are given. Monodisperse hollow nanoparticles of roundish shape constituted probably by iron oxides were discovered using atomic-force and electron microscopy. The hollow structure of nanoparticles was ascribed to the nanoscale Kirkendall effect. The role of iron bacteria was assumed as a factor controlling oxidation under the formation of nanoparticles in the films of the surfaces of natural crystals.

天然石英晶体表面薄膜中的氧化铁纳米颗粒

给出了对来自 Sinilga 矿区（亚极地乌拉尔，俄罗斯）的石英菱形表面薄膜纳米形态的研究结果。使用原子力和电子显微镜发现了可能由氧化铁构成的圆形单分散中空纳米粒子。纳米粒子的中空结构归因于纳米级柯肯德尔效应。铁细菌的作用被认为是在天然晶体表面薄膜中纳米颗粒形成过程中控制氧化的一个因素。
