Simple water based hot plate syntheses for complex nanostructures like Nanotubes, Nanoneedles and Nanowires — •Mady Elbahri, Seid Jebril, Dadichi Paretkar, and Rainer Adelung — Christian Albrechts Universitaet kiel

1-D one dimensional nanostructure like nanowire , nanotube, nanorods, etc. have attracted significant attention due to their unique properties and hence find various applications1. Because such structures represent the gateway towards the world of nanoscale devices, numerous approaches have been developed. However, a huge interest for cost effective as well as rapid methods covering large areas with complex nanostructures still remains a challenge. We present a family of new water based non equilibrium syntheses of nanostructures on a hot plate. Within this approach, structures like the formation of carbon nanotubes, square millimeter large arrays of upstanding Na2CO3 nanowires with typical length of 20 micrometer but diameters below 100 nm or surface nanowires from ZnO nanorods was performed within. Reproducibility and properties will be critically discussed together with possible applications. [1] Y. Xia et al., Adv. Mater 15, 353, (2003)
