and the other half below the initial starting plane. They then electroplated a nanocrystalline alloy of nickel and iron to form a sleeve around the struts and nodes of the trusses, with the thickness controlled over a 75-to 400µm range by the deposition time. The loading stiffness more than doubled and the peak strength increased 10-fold. The specific strength, which accounts for changes in density, also increased almost threefold. -MSL Scripta Mater. 58, 247 (2008).
