用原子力显微镜（AFM）获得了压制粉末样品的原子分辨图像。该技术是成功的解决的颗粒，域，和原子结构的pismo蛤（蒂韦拉stultorum）和海胆（Strongylocentrotus purpuratus）壳和市售碳酸钙（CaCO 3）和碳酸锶（SrCO 3）粉末。对髋臼杯进行研磨和随后的压制不会破坏这些材料的微观结构。原子力显微镜的原子分辨率成像能力可以应用于多晶样品的压制粉末的粒度小至50微米。这些结果表明，原子力显微镜是一个很有前途的工具，材料科学和生物矿化的研究。
Atomically resolved images of pressed powder samples have been obtained with the atomic force microscope (AFM). The technique was successful in resolving the particle, domain, and atomic structure of pismo clam (Tivela stultorum) and sea urchin (Strongylocentrotus purpuratus) shells and of commercially available calcium carbonate (CaCO3) and strontium carbonate (SrCO3) powders. Grinding and subsequent pressing of the shells did not destroy the microstructure of these materials. The atomic-resolution imaging capabilities of AFM can be applied to polycrystalline samples by means of pressing powders with a grain size as small as 50 micrometers. These results illustrate that the AFM is a promising tool for material science and the study of biomineralization.
