“…Pressure is able to have also a strong influence on the thermodynamic driving force and nucleation rate for each phase [25]. In addition, the long range atomic rearrangement will be depressed at high pressures leading to a change of the microstructure and phase composition for solidification products [26,27].…”

Materials chemistry under high pressures is an important research area opening new routes for stabilizing novel materials or original structures with different compositions (oxides, oxoborates, nitrides, nitridophosphates, sulfides,...).Due to the varieties of chemical compositions and structures involved, high pressure technology is also an important tool for improving the investigations on chemical bonding and consequently the induced physico-chemical properties.Two different approaches can be described: (i) the chemical bond is pre-existing and in such a case, high pressures lead to structural transformations, (ii) the chemical bond does not exist and high pressures are able to help the synthesis of novel materials. In both cases the condensation effect (∆V < 0 between precursors and the final product) is the general rule. In addition, through the improvement of the reactivity, high pressures can lead to materials that are not reachable through other chemical routes.

“…The high pressures generated when a cavitation bubble collapses are thought to be associated with sonocrystallisation [12,16,22] although the exact mechanism is still the subject of debate [13,[22][23][24][25][26][27]. The main problem in the experimental validation of the theoretical models is that the processes involved occur on a microscopic level and take place over very short time scales making them difficult to observe.…”

“…The process of nucleation has even been initiated experimentally by a single acoustically levitated cavitation bubble [5,6]. Although the detailed mechanism is not proven yet, a good candidate for the nucleation trigger is the strong compression in a pressure wave close to the collapsing bubble [7][8][9][10].…”

Ice Crystallization Induced by Optical Breakdown

et al. 2007

Ice crystallization in supercooled water has been initiated by focused Nd:YAG laser pulses at 1064 nm wavelength. The pulses of 8 ns duration and up to 2 mJ energy produce a bubble in the supercooled liquid after optical breakdown and plasma formation. The subsequent collapse and disintegration of the bubble into fragments was observed to be followed by ice crystal nucleation in many, but not all cases. Details of the crystallization events have been investigated by high-speed imaging, and nucleation statistics and crystal growth rates are given. It is argued that homogeneous nucleation in the compressed liquid phase is a plausible explanation of the effect.
