Summary: The equilibrium cluster fluid state of a symmetric binary mixture of particles with short-ranged attractive and long-ranged repulsive interactions was studied through Monte Carlo simulations. The clustering behavior of the system was found to be controlled by the cross-interaction between the two types of particles. Different levels of cross-attraction led to different clustering behaviors, from independent giant clusters to composite clusters.

Summary: The study reveals that single bubbles or foams formed in mixtures of liquids have longer lifetimes due to differences in bulk and interfacial concentrations inducing a thickness dependence of surface tension, resulting in a stabilizing Marangoni effect. Nonlinear variations of surface tension with composition in asymmetric binary mixtures are found to be associated with large foam lifetimes. This research sheds new light on foamability without added surfactants by discussing variations in surface tension based on a simple thermodynamic model.

Summary: Using acoustofluidic channels formed by capillary bridges, two models are developed to describe nodes formed by leaky and by evanescent waves. The study shows that nodes can be formed without resonance in the fluid, and node separation can be controlled by water depth. The capillary bridge channel developed in this research is simple and low-cost, and has potential applications in filtration, separation, or patterning of biological species in rapid immuno-sensing.

Summary: This study demonstrates that capillary suspensions can be formed by mixing particles with partially saturated 1-alkanol/water solutions, without the need for temperature induced phase separation. Additionally, partially miscible oil suspensions can also form capillary bridges even during the drying process when exposed to high humidity.

Summary: The mechanism of mechanical and hydraulic properties of unsaturated clays at the nanoscale was investigated using molecular dynamics and microscopic test methods. The results showed that various factors, such as droplet coalescence, wettability, and capillary force, influenced the behavior of the system. Fitting the critical conditions of liquid bridges provided insights into macroscopic unsaturated theory and long-term experimental observations.

Summary: This study investigates the thermocapillary convection and interface deformation of a liquid bridge surrounded by a heating/cooling ring in the presence of another immiscible liquid under the influence of gravity through 2D axisymmetric simulations. The results show that there is a significant difference in flow and heat transfer patterns between the heating and cooling cases. The interfacial velocity and bridge deformation are more stable when a cooling ring surrounds the liquid bridge. Moreover, a cooling ring reduces deformation, while a heating ring enhances interface deformation.

Summary: Cells can induce the formation of condensates and liquid droplets by varying the concentration of molecules in the cytoplasm or on the membrane. The size and growth rate of the clusters are controlled by concentrations, valence, and bond strength. If one species is in large excess, it saturates the binding sites of the other species, leading to kinetically arrested cluster coarsening and effective size selection.

Summary: Numerical calculations demonstrate an anomalous liquid expansion when quenching a binary mixture to low pressures in the vapor phase. This evaporation-induced expansion is attributed to pressure imbalance near the liquid-vapor interface, influenced by the complex thermodynamics and dynamic asymmetries of binary mixtures. Careful modulation of pressure quench in the vapor phase can induce spinodal bubble formation inside the liquid phase.

Summary: The phase separation of mixtures composed of choline, tetramethylammonium, and tetraethylammonium chlorides with methacrylic, butyric, and isobutyric acids as solvents was investigated. Liquid-liquid equilibrium experiments were conducted under atmospheric pressure and the data were analyzed using the NRTL solution model. Measurements of density, viscosity, Kamlet-Taft parameters, and solvent polarity (ET(30)) were performed for the coexisting liquid phases. The binary biphasic system obtained in this study showed potential for extraction processes, particularly in the purification of methacrylic acid from a phenolic inhibitor.

Summary: Spherulites are growth patterns in binary mixtures characterized by spherical form and misoriented angles at low grain boundaries. A phase field model is used to describe the dynamic growth of spherulites, with discretization in time based on an implicit splitting scheme. Numerical results demonstrate the formation of Category 1 spherulite using predictor-corrector continuation method.

Summary: The study demonstrates that binary fluid mixtures behave similarly to confined pure fluids in nanopores, with capillary condensation and evaporation occurring only when the bulk mixture outside the nanopores is in the vapor phase. Hysteresis occurs at low temperatures, but other than that, the capillary condensation and evaporation curves coincide, indicating no phase-coexistence region for confined mixtures.

Summary: In this study, we investigate oppositely charged colloids with size and charge asymmetry under the influence of an external electric field. The large colloidal particles are connected by harmonic springs, arranging themselves into a hexagonal lattice, while the small particles demonstrate fluid-like motion without bonds. Our findings reveal that the system exhibits cluster formation with stable wave packets in the vibrations of the large particles when the external driving force exceeds a critical value.

Summary: Understanding the morphology formation process of solution-cast photoactive layers (PALs) is crucial for optimized solar cell fabrication. A Phase-Field computational framework is developed to simulate PAL processing. This study explores the crystallization mechanisms of non-evaporating, crystallizing binary mixtures and provides a comprehensive description of the thermodynamic and kinetic mechanisms associated with different crystallization modes.

Summary: In this study, a binary system of IL-OH and IL-Ester ionic liquids (ILs) was prepared and characterized. The physico-chemical properties such as density, viscosity, thermal stability, and refractive index were determined for the binary system. The addition of IL-Ester increased the viscosity and refractive index, while decreasing the density and thermal stability. The study also provided insights into the mixing behavior and interactions among these binary mixtures.

Summary: This study used data from the European Space Agency's Rosetta mission to track the motion of particles in image sequences and derive their velocities and accelerations. An algorithm was developed to locate the particles and reconstruct their tracks using the image sequences' pair-nature. The study found significant information about potential genuine particle tracks and obtained preliminary results on velocity, acceleration, and radius distributions.

Summary: Directional wicking and spreading of liquids can be achieved by specifically designed topographic features that break reflection symmetry. This study investigates the formation and stability of wetting films during the evaporation process on surfaces with a micro-pattern of triangular posts. The evolution of drops is controlled by post density and aspect ratio, with no influence of post orientation on contact line mobility. The experiments confirm previous numerical results, showing that the conditions for spontaneous retraction of a wicking film only weakly depend on the edge orientation relative to the micro-pattern.
