“…Alloys and compounds based on gallium and indium have many favorable and comfortable properties. They are used in semiconductor devices based on III-V and III-VI compounds and superconductors [2], as heat transfer agents in nuclear reactors [3], as lubricating materials, in high temperature thermocouples, etc. There is also a relatively new domain of application of Ga -In alloys, the fabrication of low temperature solders which are of great importance in semiconductor technology [2,4].…”

Electrophysical and structure-sensitive properties of liquid Ga-In alloysThe broad interest in the thermophysical properties of gallium-based melts is stimulated by their extensive use in various applications, such as sliding contacts, heat-sensitive elements of liquid-metal thermometers and thermocouples, carrier liquid for conducting magnetic fluids and the working medium for physical modeling in solidification and magnetohydrodynamic studies. The electrical conductivity, thermal conductivity, viscosity, density and thermoelectric power were determined for different alloy compositions in a wide temperature range below and above the liquidus. Respective scaling relations are proposed. A comparison with data available in literature is given.

“…In our simulations, we therefore use the fact that in the presence of the oxide layer, the optical properties of EGaIn and pure liquid gallium are similar 21,43 . In the UV-visible spectral region, the dielectric permittivity function of pure liquid gallium can accurately be represented by a simple Drude-like model 13,21,43 . Thus, as experimental data for the dielectric permittivity of EGaIn (ε EGaIn ) in the UV spectral region are not available, we employ the Drude model to extrapolate experimental values of ε EGaIn obtained for the visible-to-NIR (400 nm to 1000 nm) spectral region 21 .…”

Nanoparticles made of non-noble metals such as gallium have recently attracted significant attention due to promising applications in UV plasmonics. To date, experiments have mostly focused on solid and liquid pure gallium particles immobilized on solid substrates. However, for many applications, colloidal liquid-metal nanoparticle solutions are vital. Here, we experimentally demonstrate strong UV plasmonic resonances of eutectic gallium-indium (EGaIn) liquid-metal alloy nanoparticles suspended in ethanol. We rationalise experimental results through a theoretical model based on Mie theory. Our results contribute to the understanding of UV plasmon resonances in colloidal liquid-metal EGaIn nanoparticle suspensions. They will also enable further research into emerging applications of UV plasmonics in biomedical imaging, sensing, stretchable electronics, photoacoustics, and electrochemistry.

“…While the galinstan was flowing, it was challenging to see the small (<1 mm), intermittently occurring oxide particles with the naked-eye or capture them with a CCD camera unless they were illuminated with a light source 9 or laser-sheet, 10 which can be spatially limited or difficult to aim exactly where needed. However, due to the thermal and optical differences between the matte oxides and the mirror-like galinstan, [11][12][13][14] an IR camera could be used to resolve and track the impurities being carried by the flowing galinstan, as shown in Fig. 5.…”

Measuring free-surface, liquid-metal flow velocity is challenging to do in a reliable and accurate manner. This paper presents a non-invasive, easily calibrated method of measuring the surface velocities of open-channel liquid-metal flows using an IR camera. Unlike other spatially limited methods, this IR camera particle tracking technique provides full field-of-view data that can be used to better understand open-channel flows and determine surface boundary conditions. This method could be implemented and automated for a wide range of liquid-metal experiments, even if they operate at high-temperatures or within strong magnetic fields.
