该数据集显示了油酸包覆的超顺磁性纳米颗粒(SPION)的团聚体尺寸和结构,其分散在热致液晶(LC)的疏水流体中,4-氰基-4 ′-戊基联苯(5CB)。分析的数据集是从使用低温透射电子显微镜(cryo-TEM)和偏振光学显微镜获得的SPION-5CB混合物的原始图像中获得的。对图像数据进行定量分析,以提取SPION及其团聚体的尺寸和团聚SPION的颗粒间间距的统计信息。该数据集支持对胶体纳米球在各向异性流体中的行为的基本理解,并有可能用作新型混合材料自动设计数据库的一部分。
This dataset shows the agglomerate dimension and structure of oleic acid-coated superparamagnetic nanoparticles (SPIONs), which are dispersed in the nematic fluid of a thermotropic liquid crystal (LC), 4-cyano-4′-pentylbiphenyl (5CB). The analysed datasets were acquired from the raw images of the SPION-5CB mixtures obtained using cryogenic transmission electron microscopy (cryo-TEM) and polarised optical microscopy. The image data were quantitatively analysed to extract statistical information on the sizes of SPIONs and their agglomerates and the inter-particle spacing of the agglomerated SPIONs. This dataset supports the fundamental understanding on how colloidal nanospheres behave in an anisotropic fluid, and has a potential to be used as a part of database for automated design of new hybrid materials.
