“…In addition, it was shown that nanobubbles disappear, when the surrounding medium was exchanged from pure water to pure ethanol. 65) A reason for this observation could be that the gas dissolves from the surface into the alcohol solution. It has been shown that the presence of water is crucial for the formation of nanobubbles, when alcohol-water mixtures with different compositions were measured.…”

In this review surface nanobubbles, which are presumably gas-filled enclosures found at the solid–liquid interface, are introduced and discussed together with key experimental findings that suggest that these nanoscale features indeed exist and are filled with gas. The most prominent technique used thus far has been atomic force microscopy (AFM). However, due to its potentially invasive nature, AFM data must be interpreted with great care. Owing to their curved interface, the Laplace internal pressure of surface nanobubbles exceeds substantially the outside ambient pressure, and the experimentally observed long term stability is in conflict with estimates of gas transport rates and predicted surface nanobubble lifetimes. Despite recent explanations of both the stability and the unusual nanoscopic contact angles, the development of new co-localization approaches and the adequate analysis of AFM data of surface nanobubbles are important as a means to confirm the gaseous nature and correctly estimate the interfacial curvature.

“…Other than pure water systems, dilute alcohol systems [15] and dilute acid systems [57] have also been used, but some water must always be present. In fact Zhang et al [15,60] pointedly displaced the water in their system with ethanol to see when the nanobubbles would disappear. The nanobubbles vanished at approximately 20 vol.% ethanol.…”

Surface nanobubbles and micropancakes are two recent discoveries in interfacial physics. They are nanoscopic gaseous domains that form at the solid/liquid interface. The fundamental interest focuses on the fact that they are surprisingly stable to dissolution, lasting for at least 10-11 orders of magnitude longer than the classical expectation. So far, many articles have been published that describe various different nucleation methods and 'ideal' systems and experimental techniques for nanobubble research, and we are now at the stage where we can begin to investigate the fundamental questions in detail. In this topical review, we summarize the current state of research in the field and give an overview of the partial answers that have been proposed or that can be inferred to date. We relate nanobubbles and micropancakes, and we try to build a framework within which nucleation may be understood. We also discuss evidence for and against different aspects of nanobubble stability, as well as suggesting what still needs to be done to obtain a full understanding.
