Summary: This study directly measured the critical size of a single capillary-condensed nanomeniscus using atomic force microscopy, revealing the relationship between surface tension of alcohols and curvature, and finding that larger curvature results in increased surface tension, affecting nucleation behavior. The research on curvature effects contributes to better understanding and accurate analysis of nucleation processes in fields such as materials science and atmospheric science.

Summary: In this study, a theoretical model based on lubrication theory and kinetically limited evaporation was developed to examine the capillary flow of evaporating liquid solutions in open rectangular microchannels. The model considered the complex free-surface morphology, solvent evaporation, Marangoni flows, and finite-size reservoir effects. The research found significant differences in flow behavior between pure liquids and liquid solutions due to solvent evaporation and solute transport. Marangoni flows were found to promote more uniform solute deposition patterns.

Summary: Motivated by industrial production of organic light-emitting-diode displays, this study formulates and analyzes a mathematical model for the evolution of a thin droplet in a shallow axisymmetric well, taking into account spatially non-uniform evaporation of the fluid. Physical experiments were conducted with cylindrical wells of varying aspect ratios to validate the mathematical model by comparing experimental results with theoretical predictions.

Summary: The origin of the difference between the deposition of suspended particles in a sessile droplet and in an axisymmetric droplet deposited on a fiber is analyzed. The shape of the droplet on a fiber and its evaporative flux are modeled to derive analytical calculations. The hydrodynamics equations in the liquid phase are solved under the lubrication approximation to determine the flow velocity toward the contact lines. The substrate curvature plays a role in contact line depinning, local evaporative flux, and liquid flow field.

Summary: In this study, we investigate the phenomenon of air invasion in a water-filled microchannel with a constriction. We find that the dynamics of the air bubble escaping the constriction is characterized by intermittent and jerky motion. This is due to the elasto-capillary coupling between the air-liquid interface and the elastic medium. The study provides insights into the role of channel geometry in the stop-and-go dynamics of the bubble. This research has important implications for biomimetic studies and understanding the propagation of air embolisms in plants.

Summary: This study investigates the influence of gravity on solute transport during evaporation of thin droplets. Two asymptotic regimes are identified based on the size of the Bond number. The results provide quantitative predictions of the size, location, and shape of the solute mass profile, taking into account the interplay between advection, diffusion, surface tension, and gravity.

Summary: This study explores and manipulates the deposition morphology of silica/polystyrene suspension droplets on hydrophobic surfaces by controlling the relative humidity. It is found that under higher relative humidity, the deposits of silica suspension droplets become thicker and smaller, while a uniform deposition is observed for polystyrene suspension droplets evaporated at a relative humidity of 15%. The capillary flow velocity inside a shrinking droplet is calculated using a mass conservation model and image analysis, and it is found that the velocity is higher at lower relative humidity.

Summary: The study found that the position of the liquid-gas interface after droplet impact is influenced by the substrate temperature, and the dynamic levitation transition of the gas film is affected by air and vapor draining as well as evaporation. In the case of low impact velocity, the transient stability of the draining gas film makes dynamic levitation less demanding than static levitation.

Summary: Gas film and nonlinear advection are two physical mechanisms affecting the rebounding of impacting drops. We reveal the dominance of the nonlinear advection regime through impacts on superheated surfaces. By measuring the gas film thickness under impacting drops, we provide evidence for the transition from the surface tension to the nonlinear inertia dominated regime.

Summary: We use a phase field simulation method to investigate liquid filling on grooved surfaces, considering both short-range and long-range liquid-solid interactions. Different wetting states are captured, and complex disjoining pressure profiles are observed. The filling transition is reversible for complete wetting and shows hysteresis for partial and pseudo-partial wetting. The critical pressure for the filling transition follows the Kelvin equation for complete and partial wetting scenarios, and distinct morphological pathways are identified for pseudo-partial wetting.

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 presents a novel heterojunction structure (SrTiO3/CN-TAL10.0) for enhanced photocatalytic water splitting (PWS). The incorporation of thiophenedicarboxaldehyde (TAL) through copolymerization significantly improves the photocatalytic activity of carbon nitride (CN) while maintaining its photostability performance. The optimized composition allows efficient isolation of photoinduced charge carriers and enhanced charge transport, resulting in a remarkable increase in overall photocatalytic efficiency.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

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.
