Gold, as a topic, is a multifaceted subject spanning materials science, chemistry, physics, and economic geology, encompassing the element’s electronic structure (5d¹⁰6s¹), exceptional corrosion resistance, high electrical and thermal conductivity, and relativistic effects underlying its characteristic color and chemical behavior. Research topics include nanoscale gold (e.g., plasmonic nanoparticles with tunable optical resonances), heterogeneous catalysis on gold surfaces, crystal defects and microstructure in bulk and thin films, and ore-forming processes governing its geochemical distribution. Gold is also studied in contexts such as bioconjugation, sensing, microelectronics interconnects, and surface functionalization via self-assembled monolayers, making it a central material in both fundamental and applied research.
A new study shows how organic molecules greatly influence the redox potential of gold nanoparticles, with differences up to 71 mV. Using experiments and computer simulations, the study highlights the important role of capping ...
