Numerous experiments suggest that bubble formation in aqueous media is initiated by stable gas nuclei. Although attempts have been made both to detect and to describe these entities, their very existence is still controversial. This paper reports a detailed investigation using light and electron microscopes. The objects identified as nuclei are found in both distilled water and gelatin, and they resemble ordinary gas bubbles. Radii are on the order of 1 μm or less and can be three orders of… 
Diffusion-driven nucleation from surface nuclei in hydrodynamic cavitation
Investigations about the role of nuclei and nucleation for the inception and formation of cavitation have been part of cavitation research since Harvey et al. (J. Cell. Physiol., vol. 24 (1), 1944,
Controlling the locus of bubble nucleation by dissolved gases in heterogeneous liquid-liquid systems.
Bubble nucleation in the oil can be inhibited or eliminated by adding water-soluble surfactants, which facilitates aqueous phase bubble nucleation and then acts as highly effective nitrogen sinks, severely reducing the flux of dissolved gas across the water-oil interface.
Reflections on cavitation nuclei in water
The origin of cavitation bubbles, cavitation nuclei, has been a subject of debate since the early years of cavitation research. This paper presents an analysis of a representative selection of
A study on bubble nuclei population dynamics under reduced pressure
The existence of cavitation nuclei is one of the necessary conditions for liquid cavitation. Bubble nucleus is the most basic cavitation nucleus, and bubble nuclei size distribution is a parameter
A physiological model of the interaction between tissue bubbles and the formation of blood-borne bubbles under decompression.
The interaction between the growth of tissue and blood-borne bubbles under decompression is explored, specifically looking at the extent to which they compete for the common resource of inert gas held in solution in the tissues.
Investigation of bubble dynamics and heating during focused ultrasound insonation in tissue-mimicking materials
The deposition of ultrasonic energy in tissue can cause tissue damage due to local heating. For pressures above a critical threshold, cavitation will occur in tissue and bubbles will be created.
Experimental and theoretical investigation of nucleation from wall-bounded nuclei in a laminar flow
April 10-15, 2016 Abstract Even though theories and models on free nuclei and wall-bounded nuclei are part of cavitation standard literature, the process of nucleation from wall-bounded nucleation
