Since thick snow or ice adhering to the surface of an antenna used for radio communication can impede telecommunication [1], methods to reduce the buildup of snow and ice are needed. Various methods have been investigated. For example, the adhesion of ice to common rubber has been measured [2], and recently, a method that takes advantage of the physicochemical properties of material surfaces ha...

Previous studies show that air pollution and wind erosion, which damage a leaf’s epicuticular wax layer, can change leaf surface properties from hydrophobic to hydrophilic. However, the dynamic response of a damaged leaf to a raindrop impact has not been investigated and could clarify the direct influence of changes in wettability on early leaf abscission. In this article, we investigate how le...

Surface heterogeneities, including roughness, significantly affect the adsorption, motion and interactions of particles at fluid interfaces. However, a systematic experimental study, linking surface roughness to particle wettability at a microscopic level, is currently missing. Here we synthesize a library of all-silica microparticles with uniform surface chemistry, but tuneable surface roughne...

Recently, there have been many studies on dehumidifiers with a low flow rate of liquid desiccant, in which a plate-type heat exchanger with internal cooling is adopted. If the low flow rate of a liquid desiccant maintains a thin liquid film on the heat exchanger surface, heat and mass transfer performance would improve, the stability of the liquid film would increase, and there would be no entr...

Sn-3.5Ag (1%Cu 1%Zn 5%Bi 5%In) Cu Au A new wettability evaluating system was developed by combining a contact angle measurement instrument, which optically and insitu measures the contact angle of molten solder, with a conventional wettability tester (meniscograph). Using this new evaluation system, a well-known experiential knowledge that the wettability for Sn-3.5Ag, a typical Pbfree solder, ...

The efficient water harvesting from air-laden moisture has been a subject of great interest to address world-wide water shortage issues. Recently, it has been shown that tailoring surface wettability can enhance the moisture harvesting performance. However, depending on the harvesting condition, a different conclusion has often been reported and it remains unclear what type of surface wettabili...

To improve the surface wetting properties of rice straw, effects of distilled water and four alkali pretreatment on the straw surface wettability were analyzed. The straw surface contact angle at different time points was measured by JC2000A contact angle measuring apparatus, optical microscope (OM) and scanning electron microscopy (SEM) combined with a linear regression technique for parameter...

A nanoporous membrane is coated with catechol-tethered poly(N-isopropylacrylamide). The thermosensitive variation of surface wettability determines the hindered diffusivity of dextran (40 kDa) through the nanopores.

Using density functional theory and geochemical speciation modelling, we predicted how solid-fluid interfacial energy is changed, when divalent cations substitute into a calcite surface. The effect on wettability can be dramatic. Trace metal uptake can impact organic compound adsorption, with effects for example, on the ability of organisms to control crystal growth and our ability to predict t...

The tuning of the surface wettability of self-assembled monolayers of two novel tetrathiafulvalenes has been achieved by electrochemical and chemical means.
