“…On the other hand, it is well known that ultrasonic vibration improves wettability of solids. This is supported, for example, by Sarasua et al [44] who reported that ultrasonic vibrations result in reduction of the contact angle with no return. Therefore, we believe that the profile of aluminum melt surface near the sonotrode is not too different from what we observed in the water model experiments.…”

“…In a previous paper the same authors [19,22] demonstrate that the combination of ultrasonic vibration with contact angle hysteresis results in a non-return mechanism that expands the droplet (Figure 1) until half the acoustic energy introduced is consumed. The non-return mechanism is therefore related to the advancing, receding and critical sliding angles.…”

“…It has been studied by many authors, including Lauterborn [13][14][15] and Mason [16], who conclude that the size, number and distribution of bubbles depend mainly on the ultrasonic parameters (amplitude and frequency) and the liquid itself (volume, surface tension, density and viscosity). However, another physical phenomenon has been described by several authors [17][18][19][20]: the contact angle is changed when liquids are exposed to low and high frequency vibration. Manor et al [21] describe a vibration driving force F [N] at megasonic frequency.…”

Green chemistry faces a major challenge imposed by the Sustainable Development Goals (6, 14 and 15) defined in the 2030 Agenda. In the case of cleaning products (detergents), the challenges often become a paradox: even if it is biodegradable, no surfactant is harmless to aquatic life. Compared to other studies in the field, this paper covers ultrasound–detergent interactions beyond the cavitation removal process. It also considers synergistic effects with regard to the initial wetting phase and final rinsing. It concludes that the best detergent–ultrasound combination is that which minimises receding and critical sliding angles. At the same time, detergent concentration should be reduced so as to just to capture grease in micelles and avoid reattachment during rinsing. In combination with ultrasound, the concentration of eco-detergents can thus be reduced by up to 10% of their nominal value while attaining the same results.

“…In this Review, we are not focusing on the surface fabrication processes to modify the wettability of surfaces; instead, we critically discuss the behavior of liquids when they come in contact with such surfaces and the implications of these interactions in various applications. Furthermore, active methods such as those using electric fields, , acoustic waves, , and magnetic fields, leverage external forces and stimuli to manipulate the behavior of liquids on solid surfaces. The present Review does not focus on such external control of surface wetting.…”

In an era defined by an insatiable thirst for sustainable energy solutions, responsible water management, and cutting-edge lab-on-a-chip diagnostics, surface wettability plays a pivotal role in these fields. The seamless integration of fundamental research and the following demonstration of applications on these groundbreaking technologies hinges on manipulating fluid through surface wettability, significantly optimizing performance, enhancing efficiency, and advancing overall sustainability. This Review explores the behavior of liquids when they engage with engineered surfaces, delving into the farreaching implications of these interactions in various applications. Specifically, we explore surface wetting, dissecting it into three distinctive facets. First, we delve into the fundamental principles that underpin surface wetting. Next, we navigate the intricate liquid−surface interactions, unraveling the complex interplay of various fluid dynamics, as well as heat-and mass-transport mechanisms. Finally, we report on the practical realm, where we scrutinize the myriad applications of these principles in everyday processes and real-world scenarios.
