“…Some researchers have been able to manipulate some metals via electric fields . The study of wetting characteristics of room temperature liquid metals is not novel . The novelty of the current study is in observing the effect of temperature on the wetting behavior of these liquid metals on smooth and structured surfaces.…”

The primary goal of this article is to measure the wetting characteristics of a low melting point metal to determine the efficacy of this type of material for possible use in thermal energy storage applications. Galinstan 1 , a commercially available alloy consisting of Gallium, Indium, and Tin is subjected to contact angle measurements on various silicon surfaces at varying temperatures. Due to the oxidation characteristics of Galinstan, all experiments are conducted in an inert nitrogen environment (<0.5 ppm oxygen) to maintain fluid-like properties. This work finds that although contact angle changes with substrate and surface structure, temperature has no observable effect on contact angle. Contact angles range from 141 on smooth silicon to greater than 160 on silicon micropillars. Although a temperature dependence is not observed over the range of temperatures studied, having wetting properties of Galinstan on various surfaces is a step toward better understanding the capabilities of this and similar materials in energy management.

“…In particular, nanoand microtextures have been used to produce hydrophobic coating on different surfaces. 57 Since some physical and chemical treatments like plasma surface modification and chemical corrosion processing change also the surface roughness, 58-60 a change in the wetting behavior is expected.…”

In this approach, Ag thin films have been prepared using electron beam evaporation technique onto a thin film of tin-doped indium oxide coated ordinary glass substrate. The fabricated thin films were annealed in various temperatures: 100, 200, 300 and 400 C and the effect of annealing on their wetting, structural and morphological properties has been investigated. Scanning electron microscopy (SEM), UV-Visible spectroscopy (UV-Vis), diffuse reflectance spectroscopy (DRS), X-ray diffraction (XRD) and contact angle measurement have been applied for the characterization and study of thin film surfaces. The results of SEM exhibit the aggregation and formation of Ag nanoparticles on the surface of substrate changed through increasing of annealing temperature. The presence of mixed In 2 O 3 -Ag phases in the as-prepared and annealed samples was confirmed by XRD pattern. Optical behavior of thin films was followed by using diffuse reflectance spectroscopy. Wettability studies showed that the contact angle of prepared thin films was influenced by various parameters such as annealing temperature, surface morphology and composition of thin films.

“…One of the severe environmental consequences of these nuclear accidents is the enormous fallout of long-lived and highly radioactive substances such as I-137, Cs-137, Xe-133, and so on. For example, the total amount of radioactivity released from the nuclear fuel into the environment at the Three Mile Island accident was about 9.25 × 10 16 Bq, of which about 60% was Xe-133, and 5.55 × 10 11 Bq was I-137 [5], whereas the Chernobyl accident reached 1.7 × 10 18 Bq [6], and the I-137 and Cs-137 leakages during the Fukushima accident were about 1.5 × 10 17 and 1.21 × 10 16 Bq, respectively [7]. These contaminations would be adsorbed and retained on the surface of the wall and equipment for a very long time [2], and even as secondary pollution carried out with mobile devices like the rescue robot.…”

A superhydrophobic surface was synthesized by a combination of an epoxy/polymethylphenylsiloxane matrix and dual-scale morphology of silica (SiO2) nanoparticles. When the amount of SiO2 reached 30 wt.%, the as-prepared surface showed a high static water contact angle (WCA) of 154° and a low sliding angle (SA) of 5°, excellent water repellency, and dirt-removal effects both in air and oil (hexamethylene). Even after exposure to as high as a 12.30 Mrad dose of gamma-rays, the composite surface still maintained its superior performance.
