我们报告的宏观收缩高达30体积%，在电化学脱合金的银-金。由于原始晶格在此过程中保持不变，我们认为，在我们的实验中，纳米多孔金的形成是伴随着大量的晶格缺陷和局部塑性变形的创建。
We report a macroscopic shrinkage by up to 30 vol % during electrochemical dealloying of Ag-Au. Since the original crystal lattice is maintained during the process, we suggest that the formation of nanoporous gold in our experiments is accompanied by the creation of a large number of lattice defects and by local plastic deformation.
