Abstract

Profile analysis tensiometry (PAT) with drops and bubbles is a successful methodology to characterize liquid–fluid interfaces. Questions about the most suitable size of drops and bubbles have been solved now on the basis of dimensionless numbers. The consideration of the standard deviation between measured and calculated liquid profiles as a sensitive measure for the applicability of PAT provides a tool for its correct use. For solutions of highly surface-active compounds, bulk depletion effects can cause systematic errors in the analysis of adsorption kinetics, equations of state, and the visco-elastic interfacial behavior of liquid adsorption layers. Great progress has been made in measurements of interfacial dilational rheology with large amplitude perturbations providing additional information about structure and dynamics of complex adsorption layers. Also, first attempts are successfully made to use artificial intelligence (AI) to enhance the efficiency of PAT applications. Thus, PAT has established a solid position in surface science.

液滴和气泡剖面分析张力测量法的进展

使用液滴和气泡的剖面分析张力仪（PAT）是一种成功的表征液-流界面的方法。有关液滴和气泡最合适大小的问题，现在已经在无量纲数字的基础上得到了解决。将测量值与计算值之间的标准偏差作为衡量 PAT 适用性的敏感指标，为正确使用 PAT 提供了工具。对于高表面活性化合物的溶液，体积损耗效应会导致吸附动力学、状态方程和液体吸附层粘弹性界面行为分析出现系统误差。通过大振幅扰动测量界面扩张流变学取得了很大进展，为复杂吸附层的结构和动力学提供了更多信息。此外，还首次成功尝试使用人工智能（AI）来提高 PAT 应用的效率。因此，PAT 已在表面科学领域确立了稳固的地位。

期刊介绍： Current Opinion in Colloid and Interface Science (COCIS) is an international journal that focuses on the molecular and nanoscopic aspects of colloidal systems and interfaces in various scientific and technological fields. These include materials science, biologically-relevant systems, energy and environmental technologies, and industrial applications. Unlike primary journals, COCIS primarily serves as a guide for researchers, helping them navigate through the vast landscape of recently published literature. It critically analyzes the state of the art, identifies bottlenecks and unsolved issues, and proposes future developments. Moreover, COCIS emphasizes certain areas and papers that are considered particularly interesting and significant by the Editors and Section Editors. Its goal is to provide valuable insights and updates to the research community in these specialized areas.
