Nanowires, nanotubes and nanocubes

During the last couple of years, synthetic procedures for the production of electrochemically synthesized nanowires have been developed in the Inorganic Materials Science lab. Via this method called templated electrodeposition, billions of free-standing metal (Au, Ni, Ag, Sn, Pt, Cu) and metal oxide (ZnO, Fe2O3, Ag7NO11, TiO2) nanowires/nanotubes with a diameter of 50-300 nm and a length of 4-6 µm can be synthesized via a very cheap and simple route; see Figure 1 for a SEM image of a cluster of nickel nanowires. Using these recipes, the synthesis of coaxial and segmented nanowires is straightforward.

A lot of different projects can be realized on the subject nanowires/nanotubes. Current research paths are focused on the investigation and improvement of the photocatalytic properties of the nanowires, the synthesis of nanocubes in squared templates, and the coupling of nanowires and nanocubes. But next to these subjects, it is also possible to create nanosensors based on nanowires aligned between two electrodes by dielectrophoresis. If you are interested in an MSc. or BSc. project on one of these subject, please contact Wouter Maijenburg (a.w.maijenburg@utwente.nl) and we will define a project based on your personal interests.
