TL;DR: In this article, the liquid phase metal-non metal transition in carbon has been studied and it is shown that at higher pressures, a quadrivalent liquid metal carbon is expected, the formation of which should occur at the known maximum in the melting line of graphite.
Abstract: It is proposed that the liquid phase metal-non metal transition in carbon takes place between an sp hybridized non-metallic liquid, with coordination number two, and a strongly correlated liquid metal in which directional bonding remains important though the hybridization and coordination number will probably change. Only at higher pressures is a quadrivalent liquid metal carbon to be expected, the formation of which should occur at the known maximum in the melting line of graphite. Motivated by a phenomenological argument, possible experiments to clarify the nature of these different liquid phases are proposed.

TL;DR: In this article, the authors describe the corrosion of materials by a liquid metal can be described in terms of the thermodynamics and kinetics of the several reactions that lead to transport of the corroded material into and through the liquid metal circuit.
Abstract: The corrosion of materials by a liquid metal can be described in terms of the thermodynamics and kinetics of the several reactions that lead to transport of the corroded material into and through the liquid metal circuit. The thermodynamic driving force for liquid metal corrosion is the equilibration of the liquid metal and all surfaces in contact with it. The measured corrosion rate, therefore, represents the net sum of the rates of each of the many reactions continuously occurring in the system as the reactants attempt to reach simultaneous equilibrium. These equilibria include the solubilities of metals and nonmetals in sodium and their interactions both in the sodium and at the solid-liquid interface. Each of these corrosion reactions has its own characteristic kinetics, which, with diffusion and transport of the reactants and products through the liquid metal, give the overall rate of corrosion.

TL;DR: In this paper, the solubility of krypton in liquid lead and liquid tin has been measured by means of radioactive 85Kr and the results show that the vibrational entropies of the gas atoms are less than those of the metal atoms corresponding to a greater vibrational frequency.
Abstract: By means of radioactive 85Kr the solubility of krypton in liquid lead and liquid tin has been measured. In the temperature range 800°c to 1300°c for lead and 1100°c to 1300°c for tin the Ostwald coefficient r (volume of gas dissolved in unit volume of metal) varies with temperature according to the empirical relation and the thermodynamic equation where 1/a 3 is the number of metal atoms in unit volume, m the mass of a. krypton atom, H is the energy needed to transfer an atom at rest in the gas into solution in the metal, and S the vibrational entropy of a krypton atom dissolved in the liquid metal. Experimental results are given in the table. The values of H are approximately equal to the surface area of a krypton atom multiplied by the surface energy of the liquid metal, and the vibrational entropies of the gas atoms are less than those of the metal atoms corresponding to a greater vibrational frequency. No solubility was detected in liquid silver showing that r10−7, i.e. when krypton pressure ...

TL;DR: The formation of room-temperature liquid metal alloys of Na and K via galvanic replacement reaction is demonstrated and the generality of this in situ approach and design principle for next-generation dendrite-free batteries is confirmed.
Abstract: Galvanic replacement reactions have been studied as a versatile route to synthesize nanostructured alloys. However, the galvanic replacement chemistry of alkali metals has rarely been explored. A protective interphase layer will be formed outside templates when the redox potential exceeds the potential windows of nonaqueous solutions, and the complex interfacial chemistry remains elusive. Here, we demonstrate the formation of room-temperature liquid metal alloys of Na and K via galvanic replacement reaction. The fundamentals of the reaction at such low potentials are investigated via a combined experimental and computational method, which uncovers the critical role of solid-electrolyte interphase in regulating the migration of Na ions and thus the alloying reaction kinetics. With in situ formed NaK liquid alloys as an anode, the dendritic growth of alkali metals can be eliminated thanks to the deformable and self-healing features of liquid metals. The proof-of-concept battery delivers reasonable electrochemical performance, confirming the generality of this in situ approach and design principle for next-generation dendrite-free batteries.
