Summary: The wetting behavior of steel surfaces can be improved by treating them with different types and concentrations of RTILs, making them more wettable by water and non-polar liquids. The water contact angle decreases with time elapsed, while the contact angle for non-polar liquids remains relatively unchanged within a specific time frame. The surface free energy of RTIL-treated steel surfaces increases, making them more prone to wetting by liquids.

Summary: This study measured the macroscopic friction behavior of water-swollen cross-linked poly(ethylene glycol)-based polyurethane coatings against a glass counter surface with varying PEG precursor mass. Experimental data was used to accurately calculate the molar mass between cross-links M-c and estimate the coating mesh size xi. The obtained friction, swelling, and indentation data were used to deduce an empirical model for the quantitative description of the aqueous friction behavior of these coatings depending on the mesh size and sliding velocity.

Summary: This paper describes a one-step, low-cost method to induce superhydrophobicity by pulsed laser deposition of laser-ablated PDMS micro/nanoparticles, which is applicable to a variety of surfaces. The technique has been successfully demonstrated on glass, PMMA, and aluminum, achieving water contact angles greater than 150° and roll-off angles less than 3°. Furthermore, this method can be used to make micron-scale patterned superhydrophobic PDMS surfaces, with potential applications in microfluidic microchannels and optical devices.

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: Experimental results show that controlled contamination is crucial for consistent surface wettability alterations after low-temperature annealing. Analysis reveals that contamination with hydrophobic PDMS may arise from the furnace, resulting in water repellency on the surface. Annealing in a contaminant-free furnace preserves initial superhydrophilicity, while annealing in a contaminated furnace leads to different wettability transitions.

Summary: We present a universal method for preparing intrinsic superhydrophobic objects of diverse polymeric materials via selective laser sintering (SLS) 3D printing technology. The method involves layer-by-layer sintering of polymeric powders and polytetrafluoroethylene (PTFE) grains following programmed digital models. The printed objects exhibit excellent anti-wetting capability and wear resistance, making them suitable for practical applications in harsh environments. This work demonstrates the universality of the method for various polymer-PTFE composite systems and contributes to the development of 3D printing functional materials.

Results show that the surface wettability and adhesion forces of the films are influenced by the treatment time, with the effects gradually degrading over time. Additionally, the plasma treatment causes morphological changes on the film surfaces, resulting in increased surface roughness.

Summary: In this study, a highly effective surfactant producer strain, Bacillus Cereus GX7, was isolated from the oil tank bottom sludge of Shengli Oil Field in China. The biosurfactant produced by GX7 was identified as surfactin, a lipopeptide surfactant, through TLC, FT-IR, and LC-MS/MS analysis. The fermentation process of GX7 was optimized using single-factor experiments, focusing on the composition of fermentation medium and fermentation conditions. Glucose and peptone were found to be the best carbon and nitrogen sources, and the optimum temperature, inoculum amount, pH, rotation speed, and fermentation time for the strain were determined to be 30°C, 1%, 7.5, 150 rpm, and 48 h, respectively. After optimization, the surface tension and emulsification index of the fermentation broth were 26.84 mN/m and 57.84%, respectively. Furthermore, the biosurfactant produced by GX7 demonstrated good stability over a wide range of temperature, pH, and salt concentration.

Summary: Effective management of biofluids is crucial for in vivo surgical interventions. Recent advances include self-sealing needles, drug-eluting stents, and shear-thinning hydrogels. However, complications associated with intestinal mucosal injury and secondary damage still persist. In this study, researchers developed an interpenetrating Janus wettability stent coating that enables unidirectional draining of excessive biofluid. They also demonstrated directional biofluid movement using a self-pumping dressing with potential applications in biofluid collection and disease diagnosis through metal ion detection. This integrated system presents an opportunity for designing wound dressings with effective biofluid management and metal ion detection capabilities.
