Summary: Researchers have found that the wetting process of water on a surface patterned with a dense array of nanopillars occurs in two stages: first, an ultra-thin precursor water film forms on the surface, and then capillary action by the nanopillars pulls the water, increasing the overall thickness of the water film.

Summary: This study investigated the influence of nanotextured surface geometry on the interfacial thermal resistance (ITR) between hydrophilic solid walls and water/ice using molecular dynamics simulations. The results showed that narrower nanostructure gaps led to decreased ITR. Particularly, when H2O molecules were in the crystal form, the local ITR significantly increased.

Summary: Inspired by the bone joint, researchers have developed a polydimethylsiloxane/alumina (PDMS/Al2O3) thermal interface material (TIM) with enhanced rheological mobility and thermal conductivity by incorporating gallium-based liquid metal (LM). The LM reduces the viscosity at the polymer-LM-Al2O3 interface, allowing for high-loading TIMs while maintaining a thixotropic state and reducing contact thermal resistance. Additionally, the merging of LM droplets bridges separate Al2O3 particles, improving interfacial thermal conduction and enhancing thermal conductivity.

Summary: The interfacial energy between a solid and a liquid plays a crucial role in determining the macroscopic wettability of the surface by the fluid and is essential for controlling fluid-transport phenomena in commercial devices/products. While there are indirect or theoretical methods to quantify this energy, there is a lack of direct experimental procedures for measuring it on realistic rough surfaces. This study proposes a methodology that utilizes dynamic contact-angle experiments on rough surfaces to determine the interfacial energy.

Summary: This study used atomic force microscopy to investigate the morphology and interactions of interfacial nanobubbles (INBs) with different surfaces. It was found that the hydrophilic probe is essential for scanning the complete morphology of INBs, and a positive correlation between INB vertical height and applied force was observed. Additionally, the interaction between INBs and hydrophobic surfaces was significantly stronger compared to hydrophilic surfaces.

Summary: The phase transition behavior of thin liquid films is influenced by both surface wettability and liquid film thickness. The mode of phase transition and onset time are affected by the thermal resistance and temperature rise rate. Additionally, bubbles are more likely to be generated in the hydrophobic region for hybrid surfaces.

Summary: In this study, the phenomenon of negative differential thermal resistance effect is observed in a solid-liquid-solid sandwiched system with a nanostructured cold surface. Non-equilibrium molecular dynamics simulations reveal that the heat flux initially increases with temperature bias for low temperature bias, but decreases counter-intuitively for high temperature bias. The negative differential thermal resistance effect at high temperature bias is attributed to the suppressed solid-liquid interfacial thermal conductance with decreasing temperature, as analyzed based on interfacial thermal resistance and density depletion length at the solid-liquid interface.

Summary: Diamond/Cu composites with Ti-coating were prepared using a liquid-solid separation technology. The formation of TiC phase improved the interfacial bonding between diamond and copper, resulting in a thermal conductivity of 457.22 W·m(-1)·K-1 for 40 vol.% Ti-coated diamond/Cu composites. The thermal conductivity showed a significant decrease with increasing TiC layer thickness, reaching a critical value of approximately 260 nm, as estimated by the differential effective medium model.

Summary: This study reports a method to produce graphitic structure welded carbon nanotube networks by interfacial welding, which significantly reduces the thermal resistance between the carbon nanotubes and improves the thermal conductivity of the nanocomposite. The nanocomposite with a 4.75wt% loading of graphitic structure welding exhibits a 410% enhancement in thermal conductivity, reaching 5.58 W m-1 K-1. Molecular dynamics simulations reveal the effect of graphitic structure welding on heat transfer behavior, providing insights for optimizing thermal transport performance in next-generation microelectronic devices.

Summary: This study investigates the use of equilibrium molecular dynamics (EMD) simulations for determining interfacial thermal resistance (ITR) at solid-liquid interfaces. Two EMD simulation methods were used to calculate ITR at interfaces under different wetting conditions. The data derived from the EMD simulation using instantaneous temperature difference could not converge due to weak intermolecular interactions, leading to inaccurate ITR calculations. A new method for calculating ITR in the frequency domain is proposed to improve accuracy.

Summary: A stretchable superamphiphobic surface is reported in this study, which can maintain stable superliquid repellency even under high tensile strain by rearranging its microstructures. The surface exhibits high deformation resistance and retains its superamphiphobicity and morphology after multiple stretch-release cycles. This research contributes to the development of reusable and low-cost platforms for biochemical detection and lab-on-a-chip systems.

Summary: Radial basis function (RBF) is gaining popularity in function interpolation and solving partial differential equations due to its accuracy and simplicity. However, the stability and accuracy of RBF methods significantly depend on the shape parameter. Several approaches have been proposed to overcome the instability issue, such as optimizing solvers and searching for the optimal value of the shape parameter.
