Summary: This study investigates the breakage of a single oil drop and droplet size distribution in a hydrodynamic cavitation device through experimental and computational methods. The results show that the droplet size can be reduced from approximately 10(3) μm to approximately 10(1) μm using the hydrodynamic cavitation device. This research provides a systematic basis for developing emulsions with desired droplet size distribution.

Summary: The article introduces the widely encountered dispersions of bubbles and drops in water and discusses the characterization of composite systems. The authors propose a one-step method using the double-syringe technique to generate aerated emulsions and demonstrate that it ensures a good scale separation between bubbles and drops. Furthermore, they show that laser diffraction granulometry can be used to rapidly assess the bubble size in these composite dispersions.

Summary: The study experimentally measured the liquid mean and fluctuating velocity field, pressure drop, gas-phase distribution, and bubble size distribution in a compact inline swirler for gas-liquid separation, validating the proposed computational approach. It was found that a coupled solution of the Population Balance Equation (PBE) with the flow equations can realistically predict the gas accumulation zone distribution.

Summary: This study investigated the influence of homogenization pressure and cycles on the physical stability and droplet size distribution of zein emulsions. The results showed that homogenization pressure had the most significant impact on the stability and droplet size distribution, with an optimum pressure of 20,000 psi. It was also observed that the optimum number of cycles varied for different parameters, and both volumetric diameter and span value should be considered for obtaining stable zein emulsions.

Summary: A novel method for preparing water-in-oil-in-water double emulsions using a two-step process with high shear device and static mixers is proposed and evaluated. The method showed efficient formation of monomodal droplet size distributions and high encapsulation efficiency, despite the shear thinning behavior of the inner emulsions. The range of droplet size variation in the double emulsion could be controlled while maintaining a residence time of less than a second, making this process a promising alternative to traditional batch processes.

Summary: Reaction-diffusion equations are widely used to model biological phenomena related to population spread and proliferation. This study extends previous work by incorporating competition between subpopulations and using a random differential equation model to estimate joint distributions of diffusion and growth rates. The results show that the random differential equation model predicts cell density more accurately and is more time efficient compared to other models.

Summary: Medium coalescence is a low energy consumption demulsification method that has been widely used in various industries. This study proposes an integrated approach to predict the demulsification performance of water-in-oil emulsion using population balance model, modified deposition model, and published breakage model. The simulation results are validated using experimental data, and a sensitivity analysis is conducted to identify the key parameters affecting demulsification performance. The integrated approach fills the research gap in demulsification simulation of water-in-oil emulsion by medium coalescence, providing insights into the relationship between droplet behavior and medium coalescence performance.

Summary: Global hydrological models (GHMs) provide important information for simulating water cycles and supporting decision-making. However, inaccuracies in GHM simulations can hinder valuable decision support. In this study, we introduce a transparent and efficient method to understand parameter control in GHMs and improve parameter estimation using global sensitivity analysis (GSA). Our findings show that traditionally neglected model parameters have a significant influence on GHM simulations, and basin attributes explain the spatial variability of parameter importance better than climate zones. Overall, our results demonstrate the effectiveness of GSA in guiding parameter estimation and improving the accuracy of GHM simulations.

Summary: Numerical simulations of silicone oil-water two-phase turbulent dispersion mixing in Q-type static mixers using CFD and a population balance model showed good agreement with experimental results. As axial length increases, the peak values of droplet size distributions gradually increase while the flat profiles become thinner. The dimensionless mean diameter decreases with increasing element number and Re, eventually stabilizing at a lower value.

Summary: Developing highly efficient bifunctional oxygen electrocatalysts is crucial for zinc-air flow batteries. Metal-organic frameworks (MOFs) and covalent organic polymers (COPs) have emerged as promising alternatives due to their designable and controllable atomic-level structures. However, their catalytic performances are limited by conductivity and catalytic activity. In this study, nanosheet FeNi-MOF and iron phthalocyanine rich COP hybrid materials are assembled through the pi-pi stacking effect to create highly efficient bifunctional electrocatalysts. The resulting catalyst exhibits superior catalytic performance and stability, making it a promising candidate for zinc-air flow batteries.

Summary: A series of catalysts with different potassium contents were prepared using solution combustion synthesis and characterized using various techniques. The results showed that the potassium content affected the phase composition and texture of the catalysts. The addition of a small amount of potassium resulted in a change in particle size distribution, leading to higher hydrogen yield. The Ni-1%K2O/Al2O3 catalyst exhibited the highest hydrogen yield at temperatures of 675 and 750 degrees Celsius.

Summary: In this study, we modified the electrolyte cubic plus association equation of state (e-CPA EoS) and integrated it with two electrical conductivity models to estimate the electrical conductivity of 11 monovalent electrolyte solutions in water. The modified e-CPA model demonstrated better performance and the hybridization with electrical conductivity models resulted in two predictive models for estimating the electrical conduction of dilute and concentrated electrolyte solutions. These predictive models showed relative average percentage deviations (AARD) of 11.15% and 13.87% over wide ranges of temperature and electrolyte concentration.
