我国科学家首次呈现纳米尺度黄金形成的动态过程

Core Viewpoint - The research team from the Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, has utilized in-situ liquid-phase transmission electron microscopy to reveal the dynamic process of gold nanoparticle formation on the surface of pyrite, proposing a new mechanism for gold precipitation induced by pyrite [1] Group 1: Research Findings - A special "dense liquid layer" exists at the pyrite-water interface, acting as a "nano-factory" that effectively catalyzes the nucleation, growth, and enrichment of gold even in fluids with extremely low gold concentrations (only a few billionths) [1] - The study provides a new perspective for understanding the genesis of gold deposits [1] Group 2: Publication Details - The related findings were published on January 20 in the international academic journal Proceedings of the National Academy of Sciences [1]
