TL;DR: In this paper, a fluid dynamics approach to modeling of fusion welding in titanium alloys is proposed, which considers the temporal and spatial evolution of liquid metal/gas interface to capture the transient physical effects during the heat source-material interaction of a fusion welding process.

TL;DR: A novel flexible metamaterial (MM) absorber that is flexible because of its liquid metal and PDMS substrate is proposed and almost perfect absorptivity is achieved at a resonant frequency of 8.22 GHz.
Abstract: In this paper, we propose a novel flexible metamaterial (MM) absorber. The conductive pattern consists of liquid metal eutectic gallium indium alloy (EGaIn) enclosed in elastomeric microfluidic channels. Polydimethylsiloxane (PDMS) material is used as a supporting substrate. The proposed MM absorber is flexible because of its liquid metal and PDMS substrate. Numerical simulations and experimental results are presented when the microfluidic channels are filled with liquid metal. In order to evaluate the proposed MM absorber’s performance, the fabricated absorber prototype is tested with rectangular waveguides. Almost perfect absorptivity is achieved at a resonant frequency of 8.22 GHz.

TL;DR: In this article, the thermal conductivity of KNO3-NaNO3 mixtures was measured by a modified transient hot-wire method using liquid metal in a capillary as a heat source.
Abstract: The thermal conductivity of KNO3-NaNO3 mixtures was measured by a modified transient hot-wire method using liquid metal in a capillary as a heat source. The method was developed for measurements on electrically conducting liquids at high temperatures. Measurements were performed on pure NaNO3 and its three mixtures with KNO3 in the temperature range from 498 to 593 K.
