Conventional gold comprising the cubic lattice is universally known for its stability. However, well known to chemists and metallurgists, this nobility is challenged by reagents such as aqua regia, which dissolve gold to form a salt solution. Among metals, mercury blends with gold to form amalgam, otherwise transition metals such as copper tend to interact with gold surfaces in electrochemical media. Herein, we report a combined experimental and theoretical investigation of the stability of Au microcrystallites bearing unconventional crystal lattices that exhibit enhanced stability towards Hg and aqua regia and practically no interaction with Cu during electroless plating. The unconventional gold is undoubtedly nobler.

比最高贵的贵族：非立方金微晶

包含立方晶格的常规金因其稳定性而广为人知。然而，化学家和冶金学家众所周知，这种贵族受到诸如王水之类的试剂的挑战，该试剂溶解金以形成盐溶液。在金属中，汞与金混合形成汞齐，否则过渡金属（如铜）往往会在电化学介质中与金表面相互作用。本文中，我们报告了结合非常规晶格的Au微晶稳定性的实验和理论研究，该非常规晶格对Hg和王水表现出增强的稳定性，并且在化学镀过程中几乎不与Cu相互作用。非常规的黄金无疑是高贵的。
