Summary: This study reports the pinch-off dynamics and initial deformation of a particle-loaded bubble in various liquids. The relative size and position of the particle with respect to the bubble, as well as the liquid properties, jointly affect the pinch-off process. The particle loading can hinder or promote the pinch-off process, resulting in different pinch-off exponents.

Summary: This paper experimentally investigates the dynamics of drop formation at low Weber numbers (We = rho(VD)-D-2/sigma). Using a high-speed camera, deionized water drops dripping from nozzles were photographed. The studied drop parameters include the limit length of the filament, the thickness and position of the neck, the size of the drop and satellite droplet, and the movement trend of the satellite droplet. The wettability of the needle nozzle is found to mainly influence the dynamic dripping process by changing the diameter of the contact circle of the three phases.

Summary: Understanding the outcome and mechanism of droplet-droplet collision is important in digital microfluidics. The collision process between a self-propelled droplet and another static liquid droplet was observed. Four interesting outcomes were identified: swallow-and-run, swallow-run-pinning, rerouting-and-run, and recoil-and-run. The behavior depends on the miscibility of the droplets and can be explained by spreading coefficients and interfacial tension gradients.

Summary: A CFD model is used to study the internal circulation vortices induced in spherical and ellipsoidal drops by an external immiscible liquid and their impact on interfacial mass transfer. The model is validated with experimental data for spherical drops and is then used to investigate the effects of relative velocity, droplet diameter, and physical properties on Sherwood number. Secondary circulation vortex is observed in symmetrical ellipsoidal drops and it significantly enhances the Sherwood number. Correlations for estimating Sherwood number are proposed for symmetrical ellipsoidal drops with and without secondary circulation vortex. The influence of shape on internal circulation pattern and Sherwood number is also studied for asymmetric ellipsoidal drops.

Summary: This study simulated Newtonian and non-Newtonian fluid flows in a vessel stirred with a Rushton turbine using CFD. The results were compared to 3D-PTV measurements. For Newtonian fluids, the turbulence models predicted similar mean flow and matched experimental velocity data well. The standard k-e model showed the closest power number to expected values and resolved a significant portion of the total energy dissipation. However, simulations of non-Newtonian flows presented challenges in reproducing the measured flow patterns and predicting mean velocity accurately. Nonetheless, the predictions for yield stress fluids were reasonably consistent with experimental observations.

Summary: Surfactants play important roles in everyday applications and industrial processes. However, the characteristic time scales of surfactant exchange pose challenges for atomistic molecular dynamics simulations. In this study, a framework combining thermodynamic principles and atomistic MD simulations was introduced, which provided a full thermodynamic description and connected the experimental control parameter with the suitable control parameter in MD simulations. The results showed a semiquantitative agreement between simulation and experimental data, but also highlighted opportunities for improving the current atomistic models in predicting surfactant affinities to aggregates.

Summary: In recent years, significant progress has been made in the understanding of surfactant adsorption at liquid interfaces. New efficient methodologies, particularly interfacial selective optical methods, have been developed to directly access the adsorbed amounts and interfacial layer compositions. Thermodynamic equations of state provide a quantitative framework for describing surfactant interfacial layers, especially at water/oil interfaces. Molecular modeling techniques have also contributed to the understanding of interfacial layer structures. Improving the interrelationships between these aspects is a challenge for current and future research, with particular focus on dilational interfacial rheology studies.

Summary: In this study, the use of deep learning generative models is proposed to predict drop coalescence in chemical engineering. By training the predictive models with generated synthetic data, the lack of training data and label imbalance problem can be overcome. A novel generative model called DSCVAE is developed for labelled tabular data, which is capable of generating consistent and realistic samples compared to the standard CVAE. By enhancing random forest and gradient boosting classifiers on synthetic data and evaluating their performances based on real experimental data, numerical results show a considerable improvement in prediction accuracy, with DSCVAE outperforming the standard CVAE. This research provides valuable insights into handling imbalanced data for classification problems, particularly in chemical engineering.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
