A mathematical model of heat transfer in continuous casting copper slabs capable of producing experimental data has been constructed and validated against experimental data provided by the management of Copper Refineries Ltd., Townsville plant in Australia. It has been used to predict the effects of major casting variables; metal temperature, casting speed and metal conductivity. The results ca...

The non-metallic inclusions are inevitable consequence of metal elaboration processes and are foreign phases always present in solid and liquid metal. The inclusions have a different shape and a size from several to several hundred micrometers (in diameter). They are randomly distributed in the matrix of the base metal and form a dispersion phase in liquid and in solid metallic phase. The non–m...

During the mineralisation of metal carbonates MCO3 (M=Ca, Sr, Ba, Mn, Cd, Pb) liquid-like amorphous intermediates emerge. These intermediates that form via a liquid/liquid phase separation behave like a classical emulsion and are stabilized electrostatically. The occurrence of these intermediates is attributed to the formation of highly hydrated networks whose stability is mainly based on weak ...

We demonstrate liquid-metal-mediated homoepitaxial crystal growth of Ge on Ge( 111) at temperatures in the range of 400-450 “C. Crystal growth proceeds by diffusion of Ge through a liquid layer, followed by precipitation onto the substrate by the vapor-liquid-solid mechanism. The liquid-metal phase at the interface is a Au-Ge alloy formed by initial deposition of a thin Au layer above the eutec...

A variety of deposition methods for two-dimensional crystals have been demonstrated; however, their wafer-scale deposition remains a challenge. Here we introduce a technique for depositing and patterning of wafer-scale two-dimensional metal chalcogenide compounds by transforming the native interfacial metal oxide layer of low melting point metal precursors (group III and IV) in liquid form. In ...

Magnetohydrodynamics (MHD) is the study of the interaction between moving, conducting fluids and magnetic fields. In this paper, the discussion is restricted to incompressible, viscous and electrically conducting fluids through pipes and ducts under an imposed uniform, oblique magnetic field. The MHD issues have become increasingly important because of the practical engineering applications suc...

Article history: Available online xxxx Flowing liquid metal PFCs may offer a solution to the issues faced by solid divertor materials in tokamak plasmas. The Liquid–Metal Infused Trenches (LiMIT) concept of Illinois Ruzic et al. (2011) is a liquid metal plasma facing structure which employs thermoelectric magnetohydrodynamic (TEMHD) effects to selfpropel lithium through a series of trenches. Th...

A biomimetic cellular-eating phenomenon in gallium-based liquid metal to realize particle internalization in full-pH-range solutions is reported. The effect, which is called liquid metal phagocytosis, represents a wet-processing strategy to prepare various metallic liquid metal-particle mixtures through introducing excitations such as an electrical polarization, a dissolving medium, or a sacrif...

Mesostructured silicates containing metal nanoparticles have been synthesised via templating around a pre-formed, metal-containing mesophase using a non-ionic surfactant.

In this paper, a theoretical study is conducted in order to establish the feasibility of a liquid metal acoustic resonator ͑liquid gallium or liquid aluminum͒ for high-amplitude acoustic oscillations. The fundamental resonant frequency typically lies between 5 and 40 kHz. The oscillations are induced by an alternating Lorentz force density applied directly to the liquid metal volume. Depending on...
