Dataset for: Rotating oil droplets driven by motile bacteria at interfaces

This project investigated the rotation of oil droplets driven by motile bacteria adhering to droplets. The dataset consists of: (a) bright field images (.tiff) of oil droplets in cell suspension; (b) z-stack images (.tiff) for droplets with adhering bacteria cell on droplet surface for three species (Halomonas, Shewanella, and Escherichia); (c) movie (.avi) of oil (dodecane and hexadecane) droplets in water for pendant drop analysis for interfacial tension measurement; (d) Contact angle and surface energy of bacteria lawn (.xls); (e) time series (.tiff) of swimming cells in aqueous suspension using confocal microscopy. The folder and file information is detailed in Metadata.xlsx. This dataset supports the publication: Dewangan, N. K., & Conrad, J. C. (2019). Rotating oil droplets driven by motile bacteria at interfaces. Soft Matter, 15(45), 9368–9375. doi:10.1039/c9sm01570a

本研究针对附着于油滴表面的运动细菌所驱动的油滴旋转现象展开探究。本数据集包含如下内容：(a) 细胞悬浮液中油滴的明场图像（.tiff格式）；(b) 三种细菌（盐单胞菌属（Halomonas）、希瓦氏菌属（Shewanella）与大肠杆菌（Escherichia））附着于油滴表面的Z-stack图像（.tiff格式）；(c) 水中油滴（十二烷与十六烷）的视频（.avi格式），用于悬滴法界面张力测定；(d) 细菌菌苔的接触角与表面能数据（.xls格式）；(e) 共聚焦显微镜拍摄的水相悬浮液中游泳态细菌的时间序列图像（.tiff格式）。文件夹与文件的详细信息详见Metadata.xlsx。本数据集支撑以下已发表论文：Dewangan, N.
