These are compared with our results from AgAuAg NWs experiments (pink diamonds) and calculations (blue triangles). 63 − 75 Benzyldimethylhexadecylammonium chloride, hexadecyltrimethylammonium bromide (CTAB, ≥96.0%), hexadecyltrimethylammonium chloride (CTAC, 25 wt % in water), hydrogen tetrachloroaurate trihydrate (HAuCl 4 ·3H 2 O, ≥99.9%), silver nitrate (AgNO 3, ≥99.9%), l -ascorbic acid (AA, ≥99%), deuterium oxide (D 2 O, 99.9 atom % D), sodium borohydride (NaBH 4, 99%), and trisodium citrate (≥98%) were purchased from Aldrich.
