“…The presence of a capping agent affects the growth process by selectively binding to specic facets and hindering their growth, leaving behind the nal product bound by the specic facets, instead of low-energy facets. 74,75 To fabricate Cu NWs, organic amines are usually employed as the capping agent to synthesize Cu NWs by the hydrothermal method, 44,45,72,[76][77][78] the hydrazine method, 36,52,[79][80][81][82][83][84] and catalytic synthesis, 85,86 which will be discussed in the following section.…”

“…Surfactant templated growth has also been proven to be useful in the synthesis of Au/Ag nanowires [90]. Briefly, this technique involves preparing a growth solution containing Au seed nanocrystals, ascorbic acid, cetyltrimethylammonium bromide, HAuCl 4 , and AgNO 3 , which can then be deposited on a carbon-coated TEM substrate in a drying growth solution film.…”

The importance of plasmonic nanoparticles in sensor development, imaging, photodiagnostics, and optoelectronics has resulted in a strong interest toward the development of straightforward synthetic methods for their preparation. In this article, we review some of the most significant advances that have been made in the synthesis of plasmonic bimetallic nanoparticles. Approaches to control morphology, with an emphasis on reactions that produce uniform particles with well-defined sizes and shapes and in high yields, are described. In addition, several characterization techniques that have been employed to elucidate the morphology of the particles are illustrated.

“…For wires grown along the [112] direction, the particles contain lengthwise twins and stacking faults, whereas no twinning was observed for either the [110] or the [100] growth direction. Furthermore, Williamson–Hall plots of X‐ray diffraction data of wormlike silver rods evidenced the presence of defects in these particles,15 and recently multitwinned as well as polycrystalline silver and gold nanorods were obtained 3b, 16…”

The spontaneous shape transformation of silver nanorods with an initial length of several hundred nanometers towards spherical particle shapes in aqueous solution is investigated by means of scanning electron microscopy, UV-vis absorption spectroscopy, anodic stripping voltammetry, and high-resolution transmission electron microscopy (HRTEM). The consolidation of the results reveals an increase in the particle number density with time. Moreover, HRTEM image analysis along the cross section of the rods evidences the presence of fivefold twinning defects which extend along the whole rod length. According to the analytical model of Monk et al. this kind of rod structure is only thermodynamically stable if the rod length is below a critical value at a given diameter. The rods investigated in the present work do not fulfill the stability criterion as they exceed the critical length. Thus, the rods decay into smaller "nanobuns" and defective as well as defect-free spheres. A mechanism based on findings from the literature, HRTEM image analysis of former rods, transition states, and the final particle structures is proposed. The defects along the surface are seen as starting points for the dissolution of material, which is reintegrated into the solid phase by homogeneous as well as heterogeneous nucleation and growth.
