WebOct 18, 2011 · Cold welding is the result of nanoscale sample dimensions and mechanically assisted fast surface-atom diffusion. We also showed that the process occurs using different metals welded together and that the quality of the welding (resistance to rupture) of Ag–Au NW is good. Our results are in good agreement with the experiments. … WebAug 31, 2015 · A new fabrication technique that produces platinum hollow nanocages with ultra-thin walls could dramatically reduce the amount of the costly metal needed to … palmdale utilities
