The Universality of Hair as a Nucleant: Exploring the Effects of Surface Chemistry and Topography

This dataset contains the raw and meta data for the publication: Universality of Hair as a Nucleant: Exploring the Effects of Surface Chemistry and Topography.

This includes atomic force microscopy, x-ray photoelectron spectroscopy, and scanning ion conductance microscopy data for the characterisation of hair samples that were used in crystallization experiments to study the effect of topography, surface charge, and surface chemistry on the nucleating ability of different hair types. A simulation model was developed for the quantitative interpretation of scanning ion conductance microscopy data, which has been included as a COMSOL report that includes all the information on the simulations. The scanning electron microscopy images were used to visualize the distribution of CaCO3 crystals grown on different hair surfaces. The metadata for finding the activity of hairs are categorized, where it was recorded whether or not nucleation occurred during contact. In situ synchrotron WAXS analysis of KNO3 crystallization was carried out in levitated droplets to learn why the formation of α-KNO3 was suppressed in our silicon oil-bound droplet-based experiments

本数据集包含用于发表论文《作为成核剂的毛发的普适性：探究表面化学与形貌的影响》的原始数据与元数据。
本数据集涵盖了用于表征毛发样本的原子力显微镜（atomic force microscopy）、X射线光电子能谱（x-ray photoelectron spectroscopy）以及扫描离子电导显微镜（scanning ion conductance microscopy）数据；该类毛发样本曾被应用于结晶实验，以探究形貌、表面电荷及表面化学对不同毛发类型成核能力的影响。研究团队开发了一款用于定量解析扫描离子电导显微镜数据的仿真模型，该模型已以COMSOL报告的形式收录，报告中涵盖了所有仿真相关细节。扫描电子显微镜（scanning electron microscopy）图像则用于可视化不同毛发表面生长的碳酸钙（CaCO3）晶体的分布情况。用于表征毛发活性的元数据已完成分类，其中记录了接触过程中是否发生成核现象。此外，本团队还针对悬浮液滴中的硝酸钾（KNO3）结晶开展了原位同步辐射广角X射线散射（synchrotron WAXS）分析，以探究为何在本团队基于硅油包裹液滴开展的实验中，α-硝酸钾（α-KNO3）的生成受到抑制。
