“…To prevent the oxidation of Sn, ethanol is used as the liquid phase. The spinodal temperature of ethanol is assumed to be the critical temperature of ethanol, 513 K, 50 higher than the melting point of Sn. Thus, Sn particles can more easily melt without the formation of TINBs at the particle surface during heating.…”

Pulsed laser melting in liquid (PLML) is a technique to produce submicrometer spherical particles (SMPs). In this process, raw particles dispersed in liquid are selectively heated, and thermally induced nanobubbles (TINBs) at the particle surface are generated and act as a thermal barrier to enhance the temperature increase during heating. However, monitoring TINBs is difficult since PLML is a low-temperature, nonplasma process. Simple transmittance measurements of monodisperse Au SMP (250 nm) colloidal solutions on a transient time scale were used to monitor the temporal dependence of the TINB thickness and the pressure within the bubble. By applying this technique for ZnO and Sn SMP formation, TINBs in the PLML process are important in promoting the formation of large particles via particle merging during laser heating.

“…In the case of water under 1 atm, it lies between 100 °C, the boiling point, and ≈ 320 °C, the spinodal decomposition temperature. [43][44][45][46] The calculation results shows that the region over 320 °C expands from region B to A as q A increases. We therefore found that the value of q A is the key factor controlling the bubble size and position.…”

a fluidic system becomes smaller, fluid pumping becomes more difficult because of the viscosity of the fluid. The viscosity causes pressure drops of up to several tens of kPa along the thin fluidic channels in practical systems. To date, various in situ fluid pumping methods to overcome this issue have been reported. [7] The Marangoni effect [8,9] is one of the most promising candidates for supplying a driving force for microfluidic manipulation. A so-called Marangoni flow is generated when a temperature gradient induces a surface tension differential that drags the neighboring liquid at a gas-liquid interface. The Marangoni flow becomes more prominent relative to flows induced by body forces such as gravity at the micrometer scale, at which the surface-to-volume ratio becomes large. It has been shown that the Marangoni effect can be used to pump discrete drops, [10,11] generate steady flow, [12,13] and manipulate microdroplets and bubbles [14,15] in microfluidic channels. In recent years, the development of thermoplasmonics has significantly improved the experimental controllability of Marangoni flows. [16] Because of the efficient plasmonic absorption of light by noble metal nanoparticles, these nanoparticles can be used as nanoheaters under light irradiation to generate temperature gradients on micro-and nanobubbles for generating the Marangoni flow [17,18] and controlling it over time. [19] The generation of the bubbles and Marangoni flow is also known to be useful for printing and sintering noble metal particles on a substrate. [20] Those particles dispersed in a liquid are collected under the bubble by Marangoni flow and sintered to form conductive lines. Such a technique is ideal for the fabrication of printed flexible electronics. [21,22] In addition, laser spots on a 2D array of nanoparticles can be used as a thin and spatio-temporally flexible heat source to control microbubble generation and Marangoni flow [23] for particle sorting, [24] particle focusing, [25] nano deposition, [26] and biosensing. [27] Despite these successful demonstrations, the Marangoni effect has not yet been widely applied for stable and rapid microfluid pumping. This is mainly because of the difficulty of controlling the temperature distribution at the gas-liquid interface, which the Marangoni flow is very sensitive to. Under continuous heating, the geometry of the gas-liquid interface is often unexpectedly modified by the evaporation of the liquid and the diffusion of dissolved gases through the interface.

Molecular dynamics (MD) simulations are conducted to investigate the effect of graphene coating on nanofilm boiling on an atomically smooth surface. Transition of boiling modes from normal evaporation to explosive boiling is observed on both bare and graphene-coated surfaces. The onset temperature of explosive boiling on the graphene-coated surface is approximately 170 K, which is extremely close to the value of approximately 160 K on the bare surface. A hydrophobic surface is also artificially fabricated to verify the effect of surface wettability on nanofilm boiling and the significance of graphene coating. The onset temperature of explosive boiling on the hydrophobic surface is much higher than that on the hydrophilic and graphene-coated surfaces. Additionally, the critical heat flux of the nanofilm boiling on the graphene-coated surface is slightly lower than that on the bare hydrophilic surface. Results confirm that graphene coating is almost useless, and even harmful to the heat transfer enhancement of the nanofilm boiling. Simulation MethodThree simulation systems, namely hydrophilic Cu, hydrophobic Cu, and graphene-coated Cu systems, are developed and shown in Figure 1. The initial configurations of the three systems are cuboid confinements with the same size of 8.39 nm (x) × 9.68 nm
