Summary: The study found that the dynamic contact angles on LIS are sensitive to changes in both the lubricant viscosity and the capillary number, and the cube of the dynamic contact angles is proportional to theta(3)(D), following a conventional hydrodynamic theory. The decreasing lubricant viscosity shifted the cube of the dynamic contact angles to high capillary numbers, and the dynamic contact angle data coincided with the prediction from a scaling law derived in this study.

Summary: Slippery liquid-infused porous surfaces (SLIPS) have wide applications in coating due to their remarkable liquid repellency. The stability of the lubricant layer within SLIPS is crucial for their functionality, but it can deplete over time, leading to degradation of liquid repellency. Wetting ridge formation is a primary cause of lubricant depletion. This article presents an understanding of wetting ridges and advancements in their investigation and suppression on SLIPS, as well as explores new directions for SLIPS research.

Summary: The study used the volume of fluid method combined with the adaptive grid method to investigate the influence of shear-thinning liquid viscosity ratio on bubble shape, rise velocity, and apparent viscosity. The results showed that bubble shape and deformation were strongly related to the viscosity ratio, and the bubble could exhibit stable or unstable states depending on the values of rheological index and characteristic time. Additionally, a viscosity blind region was observed behind the bubble under certain conditions, which tended to reduce the bubble rise velocity at large time.

Summary: The effect of magnetic field on the wettability and mobility of droplets on structured fluids is not well understood. This study manipulates the behaviors of water droplets on a film of thermotropic liquid crystals and finds that the static wetting behavior and static friction depend on the liquid crystal mesophases, while a magnetic field has no measurable effect on these properties. However, the droplet dynamics can be affected by a magnetic field on a particular liquid crystal film and this is dependent on the direction and strength of the magnetic field. The study also proposes a scaling argument using the magnetic coherence length to interpret the results.

Summary: Splashing of liquid droplets onto a substrate is a complex fluid mechanical process, especially when using nanofluids. Even though the addition of nanoparticles to a Newtonian fluid does not change its viscosity, it significantly affects the splashing transition. While splashing is often simplified as a simple material subjected to a complex flow, the impact of nanoparticles complicates the problem. Hence, the study of the rheological properties of nanosuspensions is necessary in understanding this complex phenomenon.

Summary: The loss of anti-icing properties on SLIPS surfaces under repetitive shear stresses is an intrinsic process related to their structure. Experiments showed that compared to SHS, SLIPS experienced dramatic degradation after repetitive icing-deicing cycles, with lower capillary pressure and the Rehbinder effect contributing to the accelerated destruction of the mechanical texture.

Summary: Researchers focus on the extensional rheological behaviors of Poly(vinylidene fluoride) (PVDF) solutions in the electrospinning process. The extensional viscosity of PVDF solutions is measured to understand the fluidic deformation in extension flows. An exponential model can be used to fit the measured values of uniaxial extensional viscosity at various extension rates, while a traditional power-law model is applicable to steady shear viscosity.

Summary: The study investigates the impact of nonlocal shear stress on gravity-driven isothermal flow in nanochannels under strong confinement. The local average density model is used and the fluid's viscosity kernel is estimated using the sinusoidal transverse force method. A continuum model is proposed to solve the nonlocal hydrodynamics problem and its solutions are qualitatively compared with the results of non-equilibrium molecular dynamics simulations.
