Summary: This study investigated the effects and limitations of a superhydrophobic (SHPo) surface in a two-phase closed thermosyphon (TPCT). The experiments revealed that at high heat fluxes, liquid collision led to flooding and decreased HTC, while at low heat fluxes, counter-current flow caused the entrainment of droplets and limited the condenser HTC.

Summary: In this study, the influence of surface wettability of metal foams on heat transfer and pressure drop characteristics of R134a refrigerant condensing flow in horizontal annular tubes was experimentally investigated. The results showed that hydrophobic metal foams increase heat transfer coefficient and reduce frictional pressure drop, while hydrophilic metal foams increase both heat transfer coefficient and pressure drop. Pore density of metal foams only affects pressure drop. Heat transfer coefficient and pressure drop gradient increase with vapor quality and mass flux.

Summary: This study developed slippery lubricant-infused porous surfaces (SLIPSs) on helically-finned grooves of copper tubes (HF-SLIPSs). The high viscosity lubricant (GPL 107) was locked by the nano-pores of the oxidized layer on the grooves. The results show that HF-SLIPSs not only improve droplet mobility and increase condensing area but also provide directional transport tracks, resulting in a short renewal time and enhanced condensation heat transfer.

Summary: In this study, molecular dynamics simulation was used to investigate droplet nucleation and growth in the Ar-Ne mixed system. Different droplet state transition modes were identified, and the interaction between NCG and droplets was considered to explain the wetting state. The disappearance mechanism of the flooding mode on nanostructured surfaces under large amounts of NCG was clarified at the nanoscale, providing insights into the NCG effect on dropwise condensation heat transfer on nanostructured superhydrophobic surfaces.

Summary: In this study, the reactive wetting dynamics of molten maleic anhydride-grafted polypropylene (MA-g-PP) liquids were modeled using molecular-kinetic theory (MKT). The dependencies of contact line friction (zeta) and viscosity (eta) were compared for reactive and nonreactive wetting polymer systems. The reactive wetting system showed a nonlinear relationship, unlike the linear dependencies observed in nonreactive wetting systems. The formation of a new interface and entanglements of polymer chains in the chemistry-affected regime contribute to the dependence of zeta on eta in the capillary regime.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
