Removal of Free Liquid Layer from Liquid-Infused Catheters Reduces Silicone Loss into the Environment while Maintaining Adhesion Resistance

“…For liquid-infused surfaces, sliding angle serves as an indicator of the fluid repellency of the surface and therefore the likelihood of resisting adhesion. [12,[34][35][36][37] We observed no difference in sliding angle between the LL and ØLL samples (Figure 1Cii, P >0.9999). Measurements of the droplet sliding velocity, [17] which provide an indication of surface uniformity, yielded similar results (Figure S2A).…”

“…[14][15][53][54] Recent RNA sequencing research has revealed that the introduction of silicone liquid to silicone solids leads to an upregulation of 10 distinct genes in P. aeruginosa while simultaneously downregulating a gene that may impede initial adhesion, although the precise mechanism behind this phenomenon remains unknown. [37] Furthermore, the presence of the free liquid overlayer is thought to contribute to increased slipperiness on the infused surface, reducing the energy required for detaching fouling organisms and facilitating their release. [8] More recently, understanding that liquid-infused silicone surfaces are more nuanced and dynamic than previously thought has been growing.…”

“…Finally, although many investigations of liquid-infused silicones have examined their ability to repel bacterial adhesion, [7][8]12,[15][16][17][18]37,[53][54][55] notably fewer have examined protein deposition. [13][14]56] However, recent work has begun to reveal not only the critical role that proteins play in infection, [45][46][47] but also the ability of liquid-infused silicones to robustly resist their deposition.…”

Anticorrosion Improvement of Waterborne Epoxy-Acrylate Coatings by Constructing g-C3N4 Functionalized by Polyaniline-Coated Zinc Phosphate

“…As a rust-inhibiting primer, zinc phosphate is commonly used . Wang et al enalapril maleate (EM), a green component of antihypertensive drugs, was selected as an accelerator to promote phosphate coating on the surface of mild steel, and the corrosion resistance of the phosphate coatings was evaluated by copper sulfate titration, potentiodynamic potential polarization (PDP), and electrochemical impedance spectroscopy (EIS). During corrosion, zinc phosphate partially releases zinc (Zn 2+ ) and phosphate (PO 4 3– ) to achieve passivation inhibition .…”

A study on improving the prediction accuracy of cold forging die life based on quantitative evaluation of phosphate film damage

“…It is a surface treatment method to protect metals from corrosion 2 or friction/abrasion 3 by using the physical or chemical properties of the compound created on the metal surface. In general, phosphate treatment for painting, which is performed for the purpose of preventing corrosion of metal surfaces, improves corrosion resistance more as the grain size decreases 4 , 5 . On the other hand, phosphate treatment for lubrication has a relatively large grain size and a large surface area, enabling it to offset the frictional force between the material and the die surface 6 .…”
