Data underlying the publication: Interfacial elasticity of colloid monolayers probed by high-frequency bubble dynamics in ultrasound

We apply ultrasound-driven bubble dynamics for high-frequency interfacial rheology of colloid monolayers. We propose and test two different protocols: an acoustic pressure sweep, akin to a stress sweep; and a radius sweep, which is equivalent to a frequency sweep. Using high-speed video-microscopy, we record the time-dependent bubble size and shape. The oscillatory dynamics of both coated and bare bubbles are compared under identical conditions. The dataset contains experimental data for both coated and uncoated bubbles. The experimental methods and conditions are described in detail in the accompanying README files.

本研究将超声驱动气泡动力学技术应用于胶体单分子层的高频界面流变学研究。我们提出并测试了两种不同的实验方案：其一为声学压力扫描法，类同于应力扫描实验；其二为半径扫描法，等效于频率扫描实验。借助高速视频显微成像技术，我们记录了气泡尺寸与形貌随时间演化的过程。我们在相同实验条件下，对比了覆层气泡与裸气泡的振荡动力学特性。本数据集涵盖了覆层气泡与无涂层气泡的全套实验数据。实验方法与实验条件的详细说明详见配套README文件。
