Summary: The two-dimensional melting of a binary mixture of cell tissues is numerically investigated in the presence of rigidity disparity, and the full melting phase diagrams of the system are presented. It is found that enhancement of rigidity disparity can induce solid-liquid transitions at both zero temperature and finite temperature. Specifically, at zero temperature, the system undergoes continuous solid-hexatic transitions for zero rigidity disparity and discontinuous hexatic-liquid transitions for finite rigidity disparity, while at finite temperature, the melting occurs via a continuous solid-hexatic transition followed by a discontinuous hexatic-liquid transition. This study contributes to the understanding of solid-liquid transitions in binary mixture systems with rigidity disparity.

Summary: The research developed a first-principles theory for polar liquid mixtures using a statistical field approach without resorting to mixing rules. It obtained simple expressions for the mixture's dielectric constant and free energy of mixing, with good agreement with measured data for simple binary mixtures. The predicted miscibility based on the derived free energy of mixing shows remarkable agreement with known data, providing a quantitative basis for the empirical like-dissolves-like rule.

Summary: Multicomponent quantum gases provide an ideal platform to study fundamental phenomena arising from interactions between different constituents. In this study, we develop a mean-field-based theory for a two-component Bose mixture, which allows us to derive analytical expressions for the phase boundary and miscibility. Unlike existing theories, our theory is applicable to the Bose-Einstein condensation phase and can handle larger interaction values.

Summary: This study investigates the fluidization of non-spherical binary particle beds with non-Newtonian power-law liquid. The effects of parameters such as particle diameter, column diameter, and rheological property of the liquid on the minimum fluidization velocity (Umf) are examined. The results indicate that Umf decreases with increasing concentration of the non-Newtonian fluid due to changes in effective viscosity. Additionally, the weight fraction of the larger diameter particle in a binary mixture is found to influence Umf. An empirical correlation is proposed to estimate Umf, and its applicability is compared with existing correlations using a genetic algorithm (GA) for assistance.

Summary: The study focuses on the miscibility effects of two-component classical fluids and the miscible-immiscible phase transition in two-component Bose-Einstein condensates. In homogeneous systems, the phase transition is governed by the competition between intra- and inter-species interactions. Conventional experiments with trapped gases show increased miscibility due to the pressure of confinement. The miscibility phase diagram of unbalanced mixtures of different atomic species is strongly influenced by the atom number ratio and gravitational sags.

Summary: This study investigates the elutriation of binary mixtures with irregularly shaped particles and different diameters in non-Newtonian liquids of different densities using an SLFB. Experimental tests are conducted to examine the impacts of particle size, column diameter, bed weight, and rheological properties of the non-Newtonian liquid on the minimum elutriation velocity (Ume). The results show that Ume increases with increasing column diameter and particle size, but decreases with increasing SCMC concentration. An empirical correlation is developed using GA-ANN modelling to predict the minimum elutriation velocity based on statistical parameters.

Summary: The functionality of amorphous multicomponent systems, especially amorphous drugs and electrolytes, depends largely on the miscibility among components. This study used SWAXS technique to monitor the mixing behaviors of three typical glass-forming binary systems with varied heat of mixing. The results showed that the Porod invariant (Q) increased significantly as the concentration fluctuation became intensified at the glass transition temperature. Additionally, the deviation of Q from the ideal mixing law weakened at elevated temperatures.

Summary: Water exhibits anomalous thermodynamic and kinetic properties, such as a maximum density at 4 degrees C and a viscosity decrease under pressure. The presence of a second critical point has been attributed to these anomalies. Through extensive molecular dynamics simulations of the TIP4P/2005 water model, we find that a hierarchical two-state model based on cooperative formation of tetrahedral structures via hydrogen bonding can unify the description of the structure, thermodynamic, and kinetic anomalies and criticality of water. This suggests the possible existence of a second critical point in water.

Summary: Glasses can relax internally even when their structure is frozen. In a two-dimensional glass former, non-constrained bonds survive the freezing of structural relaxation, leading to persistent internal relaxation. This study directly visualizes the internal relaxations in a glass through observations of a mechanically driven granular system, revealing the emergence of slow beta relaxation as the structure relaxation freezes.

Summary: Liquid foams exhibit plastic responses to external perturbations, which are closely related to their mechanical properties and affect foam lifetime, deformability, elasticity, and fluidity. This paper investigates the rearrangement dynamics of foams near a dry-wet transition and observes a transition from individual rearrangements to collective rearrangements. The occurrence of collective rearrangement events follows a Poisson distribution, suggesting little correlation between discrete events. These findings contribute to the understanding of dynamical properties of soft jammed systems and have implications for various scientific fields including biology, materials science, and food science.

Summary: Research shows that the preparation protocol of glass determines the crystal growth mode. Traditional glass, prepared by fast quenching, exhibits fast growth with active interface dynamics, while uniform glass, prepared by density homogenization, grows via intermittent avalanche-like dynamics localized at the interface, combining localized mechanical defects and exceptional mechanical stability imposed by the glass phase.

Summary: In this study, the scraping behaviors of foam by a rigid plate on a substrate were investigated. The results reveal that the coupling effect between gas bubbles and liquid strongly affects the scraping process of foam, which is different from simple liquid systems. Three different scraping patterns were observed, and the upper limit of homogeneous scraping could be explained by a theoretical model.

Summary: Understanding the structural ordering upon slow cooling in the absence of crystallization or phase separation is crucial for understanding glass transition. We found that the exotic compositional order has a direct impact on the structural relaxation dynamics, even without any thermodynamic signature. This raises fundamental questions about the role of unconventional structural ordering in glass transition.

Summary: The behaviour of ions solvated in water is highly ion-specific and can be explained by considering the interplay between ion-water and inter-water interactions as well as the bond-orientational order of the hydration shell. This study provides insight into the ion-specific effects observed in salt solutions and their impact on solution dynamics. The findings have fundamental implications for ionic processes in aqueous solutions, offering a physical principle for electrolyte design and application.

Summary: Nonphononic vibrations have been identified as a fundamental feature that differentiates glasses from crystals. By studying the vibrational properties of three-dimensional model glasses, it has been found that stringlike vibrations are the universal origin of the boson peak in both 2D and 3D glasses with isotropic interactions. Furthermore, these vibrations coincide with the Ioffe-Regel limit of transverse phonons. These findings shed light on the origin of low-temperature glass anomalies and inspire further research.

Summary: This study numerically investigates the nucleation process during the deposition of a glassformer and compares it with quenched counterpart and bulk system. It is found that all three systems uniformly nucleate crystals within a certain temperature range. The deposited layer shows the formation of ordered domains, with faster relaxation dynamics towards the free surface even in its as-deposited state. Additionally, the nucleus initially grows in an isotropic symmetrical manner but eventually shows sub-3D growth with a preference for growth along the basal plane, regardless of the layer production procedure.
