“…We have considered possible photomechanical mechanisms that could induce nucleation, e.g., cavitation of bubbles, 9,10 or sound-induced nucleation. 8 Photomechanical effects have been observed at much higher laser power densities obtained by focussing the laser pulses.…”

We report the observation of non-photochemical laser-induced nucleation (NPLIN) of sodium chlorate from its melt using nanosecond pulses of light at 1064 nm. The fraction of samples that nucleate is shown to depend linearly on the peak power density of the laser pulses. Remarkably, we observe that most samples are nucleated by the laser back into the enantiomorph (dextrorotatory or levorotatory) of the solid prior to melting. We do not observe a significant dependence on polarization of the light, and we put forward symmetry arguments that rule out an optical Kerr effect mechanism. Our observations of retention of chirality can be explained by decomposition of small amounts of the sodium chlorate to form sodium chloride, which provide cavities for retention of clusters of sodium chlorate even 18 °C above the melting point. These clusters remain sub-critical on cooling, but can be activated by NPLIN via an isotropic polarizability mechanism. We have developed a heterogeneous model of NPLIN in cavities, which reproduces the experimental data using simple physical data available for sodium chlorate.

“…Experimental results by Soare et al (2011), carried out using an aqueous solution of an inorganic salt, (NH 4 ) 2 SO 4 , give an appreciation of the extreme dynamics of a laserinduced vapour bubble. During the bubble lifetime of about 200 μs, from nucleation to collapse, the bubble reaches a maximum radius of roughly 700 μm and attains an interface velocity of well above 20 m/s.…”

“…After this period, the growth rate becomes limited by the mass-transfer rate across the bubble-liquid interface which is in turn restricted by the ability of the liquid to transport heat to the interface. In the case of the bubble described in Soare et al (2011), the critical time that determines the transition from the inertia-controlled to the thermalcontrolled regime is estimated as ~3 ns. Therefore, it seems that the thermal effects are governing the bubble growth rate already after a few nanoseconds and those effects need to be considered in numerical simulations.…”

We use in this work numerical simulations to investigate the evolution of a laser-induced vapour bubble with a special focus on the resolution of a thin layer of liquid around the bubble. The application of interest is laser-induced crystallization, where the bubble acts as a nucleation site for crystals. Experimental results indicate the extreme dynamics of these bubbles where the interface during the period of 200 μs, from nucleation to collapse, reaches a maximum radius of roughly 700 μm and attains a velocity of well above 20 m/s. To fully resolve the dynamics of the bubble, the volume of fluid (VOF) numerical framework is used. Inertia, thermal effects, and phase-change phenomena are identified as the governing phenomena for the bubble dynamics. We develop and implement into our numerical framework an interface phase-change model that takes into account both evaporation and condensation. The performed simulations produce qualitatively promising results that are in fair agreement with both experiments and analytical solutions from the literature. The reasons behind the observed differences are discussed and suggestions are made for future improvements of the framework.

“…Many nucleation promoting and controlling technologies have been reported. [2][3][4][5][6][7] All these attempts are aimed at establishing a moderate nucleation environment with low nucleation barrier to promoting nucleation under controllable conditions, which dominated the crystal size distribution (CSD) and crystal habit to a large extent and could strongly influence end-product quality, functionality, and downstream separation processes. [8][9][10] In recent decade, with the development of membrane material and membrane process research, membrane distillation crystallization process was proposed for hen egg white lysozyme crystallization.…”

The membrane assisted cooling crystallization was proposed and investigated by the simulation and experiments. The developed process model concerned the supersaturation evolution on the membrane interface, the combined nucleation rate in the crystallizer. The impact of different membrane on reducing the nucleation barrier was investigated by introducing the metastable zone width theory. The influence of membrane distillation conditions on the crystal nucleation and growth kinetic was uncovered based on the simulation and experiments results. The experimental results indicated that membrane assisted cooling mode with optimized profiles did improve the crystal size distribution and crystal habit comparing with conventional cooling mode. Terminal coefficient of variation decreased from 55.4 to 33.9 under similar mean crystal growth rate, 2.27 3 10 27 m s 21 (conventional cooling) and 1.98 3 10 27 m s 21 (membrane assisted cooling). Finally, the brief summary on the advantages and key issues of this propose membrane assisted crystallization operation were concluded.
