Research Abstract:
Nanoporous gold made by selective dissolution of silver from Ag-Au alloys immersed in nitric acid. (A) cross-section of dealloyed Au32%Ag68% thin film. (B) Plan-view of dealloyed Au26%Ag74% bulk material. The porosity is open and ligament spacings as small as 5 nm have been observed. Measurements more info
