TL;DR: In this paper, it was shown that a compound layer of necessary thickness to promote good wettability is formed when metal alloy is in liquid state, which is an important fact for high-temperature capillarity science.
Abstract: In a number of non-equilibrium liquid metal/solid contact systems, when chemical boundary reaction occurs and intermediate compound is formed, a high degree of wettability takes place. So wettability is commonly related to the chemical phase formed at the phase boundary. The microscopic studies which reveal interface layer of a new phase confirm this point of view. In an investigation of interface boundary at high-temperatures by new neutron spectroscopic techniques, intermediate compound layer has not been detected when a metal alloy, containing adhesion-active element (titanium), was in a liquid aggregate state. This is an important fact for high-temperature capillarity science. In the present paper, this question is discussed, and proof (experimental data and theoretical consideration) is given to support the contention that compound layer of necessary thickness (usually, very small) to promote good wettability is formed when metal alloy is in liquid state.

TL;DR: In this article, the trend of the surface tension temperature coefficient has been analyzed as a function of different operative parameters, highlighting some crucial points such as the dependence of the temperature coefficient on the accuracy of surface tension experimental data and the influence of the dissolved oxygen.
Abstract: In order to point out the interactions of oxygen with a liquid metal and to study the influence of the actual operating conditions, dynamic surface tension measurements of a liquid test metal (tin), were performed under vacuum conditions by using the large drop method. This classical method has been improved by applying a new experimental procedure which allowed to obtain reliable surface tension measurements at high temperature as a function of time and varying the oxygen content. Further, complementary information on molten metal-oxygen interactions can be obtained. In particular, in this work, the trend of the surface tension temperature coefficient has been analysed as a function of different operative parameters, highlighting some crucial points such as the dependence of the temperature coefficient on the accuracy of the surface tension experimental data and the influence of the dissolved oxygen. It was demonstrated that the surface tension and its temperature coefficient do not depend on the quantity of dissolved oxygen when this is inside a certain range of values.

TL;DR: In this article, the authors used EGaIn as an aluminum reservoir to prepare LDH and metal organic framework (MOFs) nano-arrays, which can be transformed into CoAl-LDO@Co-C in the subsequent annealing process performed under nitrogen environments.

TL;DR: The existence of only one potentially viable option for solid PFCs, though, constitutes one of the most significant restrictions on design space for DEMO and follow-on fusion reactors as mentioned in this paper.
Abstract: At present, the only solid material believed to be a viable option for plasma‐facing components (PFCs) in a fusion reactor is tungsten. Operated at the lower temperatures typical of present‐day fusion experiments, tungsten is known to suffer from surface degradation during long‐term exposure to helium‐containing plasmas, leading to reduced thermal conduction to the bulk, and enhanced erosion. Existing alloys are also quite brittle at temperatures under 700°C. However, at a sufficiently high operating temperature (700 – 1000 °C), tungsten is self‐annealing and it is expected that surface damage will be reduced to the point where tungsten PFCs will have an acceptable lifetime in a reactor environment.The existence of only one potentially viable option for solid PFCs, though, constitutes one of the most significant restrictions on design space for DEMO and follow‐on fusion reactors. In contrast, there are several candidates for liquid metal‐based PFCs, including gallium, tin, lithium, and tin‐lithium eutecti...
