Complete wetting is a universal phenomenon associated with interfaces separating coexisting phases. For example, in the pure gluon theory , at T c an interface separating two distinct high-temperature de-confined phases splits into two confined-deconfined interfaces with a complete wetting layer of confined phase between them. In supersym-metric Yang-Mills theory, distinct confined phases may c...

The (pre)wetting behavior of an annealed polyelectrolyte (PE) brush by an electrolyte solution that is strongly segregated from an apolar phase is analyzed. In this complex interface, there are interactions on various length scales. There are short-range interactions with the (uncharged) surface, and there are interactions on the length scale of the brush height. Using either the ionic strength...

– We study a Langevin equation describing non-equilibrium depinning and wetting transitions. Attention is focused on short-ranged attractive substrate-interface potentials. We confirm the existence of first-order depinning transitions, in the temperature-chemical potential diagram, and a tricritical point beyond which the transition becomes a non-equilibrium complete wetting transition. The coe...

Wetting properties of biomaterials, in particular nanomaterials, play an important role, as these influence interactions with biological elements, such as proteins, bacteria, and cells. In this study, the wetting phenomenon of titanium substrates coated with selenium nanoparticles was studied using experimental and mathematical modeling tools. Importantly, these selenium-coated titanium substra...

Qualitative changes in the local (pore level) wetting e&ciency of a porous catalyst as a function of catalyst wettability are proposed based on monitoring the 1-D motion of the solid-liquid-gas contact line. As catalyst wettability is increased, the resulting wetting e&ciency is likely to show two distinct transitions viz., (1) a sudden decrease that is inspired by coalescence of neighboring ri...

1. The penetration of sodium sulphacetaamide into the ocular tissues has been studied, both in living'rabbits and in isolated ocular tissues. 2. Application of the drug with a wetting agent, Duponal ME dry, increases the penetration of sodium sulphacetamide into and through the cornea. 3., Removal of the corneal epithelium causes a great increase in the penetration of the sulphonamide into antd...

We present a theoretical study of wetting phenomena and interactions between liquid–vapor interfaces based on the local density functional theory. The focus is mostly on the impact of longrange van der Waals interactions both within the fluid and between the fluid and substrate. For the latter, we consider two models – hard wall and soft wall approximations – differing by the role of steric eff...

Wetting presents in two forms, enuresis and incontinence. Enuresis is defined as wetting when no underlying anatomical or functional abnormality of the urinary tract can be detected. A diagnosis of incontinence implies the presence of an underlying anomaly that requires investigation and treatment. However, the diagnosis of incontinence in children is not simple. When an adult presents with wet...

In order to better understand the behavior and governing characteristics of the wetting transparency phenomenon observed in graphene-coated surfaces, molecular dynamics simulations were coupled with a theoretical model. Graphene-coated silicon was selected for this analysis, due to potential applications of hybrid silicon-graphene materials as detectors in aqueous environments. The results indi...

Temperatureand excitation-power-dependent photoluminescence measurements were carried out for the multilayer structure of Ge islands grown on a Si~001! substrate by gas-source molecular-beam epitaxy. When the excitation power increases from 10 to 400 mW, the photoluminescence peak from the Ge islands showed a large linear blueshift of 34 meV while that of the wetting layers did not change much....
