Spectroscopic evidence for a gold-coloured metallic water solution

A universal all-solid synthesis for high throughput production of halide perovskite

“…We synthesized the MASnI 3 from precursors of MAI and SnI 2 powder in a similar FAST-based route to MAPbI 3 . Figure 4f displays the final disc sample where there is an obvious metallic shine (suggesting the existence of plenty of conduction electrons and thus induced plasmon frequency threshold effect in the sample) 41 , which is consistent with the higher carrier density (9 × 10 17 cm −3 ) of this Sn-based material 42 . The SEM images of the FAST-MASnI 3 also show a compact packing of neighboring crystal grains (Fig.…”

NaK alloy: underrated liquid metal

“…In a recent article, Mason et al reported that metallic water solutions can be prepared via massive electron doping by reacting water with alkali metals. 104 The explosive behaviour of the reaction between water and alkali metals can be suppressed by adsorbing water vapour at a low pressure of about 10 −2 Pa onto drops of the liquid NaK alloy ejected into a vacuum chamber. This approach resulted in the formation of a transient gold-coloured layer of a metallic water solution covering the metal alloy drops (Fig.…”

Viewpoints on the 11th International Meeting on Atomic and Molecular Physics and Chemistry

“…In his invited talk, Hans Christian Schewe reported on experimental studies of electrolyte-tometal transition in liquid alkali-metal ammonia solutions using liquid microjets and droplets in vacuum as developed in his laboratory in Prague, as well as on his recent experiments showing spectroscopic evidence of a metallic water solution. 23 The invited talk of Milan Oncǎḱ focused on the modeling of excited-state dynamics of hydrated metal ions in the gas phase, M + (H 2 O) n , M + = Mg + , V + , and Al + . 24,25 The Wednesday program was opened by the talk of Dr. Jun Ye, who presented an overview of the recent state of the art experimental techniques to control molecules in optical lattices as well as using these techniques to reveal the quantum stateresolved reaction dynamics.…”

“…This talk was also one of the Best Hot Topic presentations.
