25. 3 (0.25 M, Aldrich, 99+%) and 3 ml of ethylene glycol solution of PVP (0.375 M in repeating unit, weight-average molecular weight ≈ 55,000, Aldrich) were simultaneously added to the ethylene glycol by means of a two-channel syringe pump at a rate of 0.375 ml/min. The reaction mixture was then continued with heating at 160°C for another 45 min. The product was dominated by cubic nanoparticles, with a small amount (<5%) of silver nanowires. These nanowires could easily be separated from nanocubes through filtration because of their large difference in dimension. In this case, the reaction mixture was diluted with water (25 times by volume) and filtered through Nucleopore membranes (Whatman, Cliffton, NJ) that contained pores 1 μm in diameter. The silver nanocubes could be recovered from ethylene glycol through centrifugation and then redispersed into water.

34. 4 (99.9%, Aldrich) aqueous solution were added dropwise to the refluxing solution. This mixture was continuously refluxed until its color became stable. Vigorous magnetic stirring was maintained throughout the synthesis.
