Summary: This study investigates the influence of particle angularity on permeability and fluid-particle interaction forces in granular materials. The results show that more angular particle assemblies are less permeable and have higher fluid-particle interaction forces, with limited and localized influence on flow rate distribution and flow tortuosity.

Summary: Emulsions play a crucial role in food products and understanding their rheological properties, especially shear viscosity, is important for their design, formulation, and processing. Texture and mouthfeel of emulsions are greatly influenced by their viscosity. This article provides a review of recent developments in viscosity modeling of concentrated emulsions, discussing and evaluating various models published in the twenty-first century using experimental viscosity data. The effects of droplet size distribution and capillary number on emulsion viscosity are also discussed.

Summary: The new tetrahedral structure model is able to comprehensively characterize both geometric frustrated configurations and local configurations associated with crystalline order in disordered packings. The study found that with increasing packing fraction, the population of tetrahedral building blocks increases, and crystal-type local configurations formed by face-adjacent tetrahedra, quartoctahedra, and bcc simplexes become more prevalent. Additionally, the local density of irregular simplexes increases more quickly with increasing packing fraction, playing a more important role in density increase in disordered packings.

Summary: The dynamics of polydisperse double emulsions driven by a Poiseuille flow within a microfluidic channel are critically affected by factors such as initial position, polydispersity index, and area fraction occupied within the emulsion. The behavior of the emulsions is found to change significantly based on these factors, impacting the motion and arrangements of internal drops. The shape changes of capsules play a key role in favoring the formation of specific nonequilibrium states, leading to motile and nonmotile configurations.

Summary: This study characterizes the entrapment of asphaltene-stabilized water/brine-in-oil emulsions in microfluidic porous media by two mechanisms: adhesion and hydrodynamic bridging. Lower water fractions result in droplet adhesion to deposited asphaltenes, while erosion and bridging between droplets become more prevalent at higher water fractions. The addition of salinity weakens adhesion but leads to increased droplet size and enhanced bridging. Higher salinity also reduces interface elasticity, resulting in larger emulsions with more erosion and bridging.

Summary: Research shows that a multilayer packaging of identical single-walled carbon nanotubes with a diameter of over 2.5 nm on a flat substrate is a multistable system, with thickness decreasing as the portion of collapsed nanotubes increases. All stationary states of the package are stable to thermal fluctuations at 300 K.

Summary: The study presents the highly controlled, microfluidic template-assisted self-assembly of CsPbBr3 nanocrystals into spherical supraparticles, achieving precise control over average supraparticle size by varying the nanocrystal concentration and droplet size. This enables the synthesis of highly monodisperse, sub-micron supraparticles (with diameters between 280 and 700 nm).

Summary: This study introduces a novel microfluidic tri-phasic step-emulsification device that can produce double emulsions with ultrathin shells in a single step, with controlled shell thickness achievable. The proposed theoretical model accurately predicts emulsification regimes and the approximation method shows good agreement with experimental findings, demonstrating the feasibility of this method for producing double emulsions and micro-capsules with controllable thickness.

Summary: A mathematical model describing the nonlinear relationship between droplet generation in a T-junction microdroplet generator is established, showing that the droplet length varies nonlinearly with the driving-pressure ratio under low capillary numbers. Experimental testing of the droplet length and driving-pressure ratio relationship is done for different T-junction geometries. A closed-loop control droplet microfluidic system is demonstrated to more accurately control droplet size, with the relative standard deviation of droplet size under different flow conditions being less than 2%.

Summary: We developed a hybrid method combining microfluidics and electrospinning to fabricate nanofibers with encapsulated microdroplets. The size and shape of the encapsulated droplets can be controlled, making it useful for applications such as nanofiber-based moisture barriers and drug carriers. This method also provides a platform for studying the stretching and splitting of droplets in polymer networks under an electric field.

Summary: Microfluidic technology has wide applications in analytical science, diagnostic technology, and micro-/nanofabrication. To prevent bubble formation in microchannels, numerical simulation and experiments were integrated to analyze the factors affecting bubble prevention, such as channel structure, wettability, and liquid flow rate. Results showed that these factors could prevent bubble formation and were validated through experiments in water-flowing microchannels, offering a promising strategy for preventing bubbles in microfluidic systems.

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.
