... Templates act as a support scaffold for metallization procedures in the fabrication of porous metals, enabling a robust processing approach which addresses fundamental difficulties in nanoporous metal assembly and FIG. 1. Sample dimensions and pore sizes of nanoporous metals (or templates) fabricated by various methods, including Ni from polymer templates prepared by BCP self-assembly, 2,68 Au lattice from polymer templates prepared by two-photon lithography, 37 Ti from powder sintering, 69,70 Cu from electrodeposition, 25,26 Fe, Cu, Ag, Co from combustion, 4 Au, 3,15,16,[71][72][73][74][75][76][77][78][79][80] Ag, 18,[80][81][82][83][84] Pt, 80,85 Pd, 17,80,[86][87][88][89] Cu, 20,[90][91][92][93][94] and Ni 19,95-98 from dealloying, as well as carbon template, 31,33,99 and polymer templates fabricated by foaming, 45 melt mixing, 44 and BCP self-assembly. 38,42,[47][48][49]68 Lines in the figure represent a range of pore sizes or sample sizes. ...
