Stability of iron (Fe) nanowires

The iron nanowires were obtained by DC electrochemical method in nanoporous anodic alumina templates (AAO). For stability tests these materials were placed in different solutions: white wine, citric acid, 0.9% NaCl, distilled water and ethanol for a 1–3 week time period. The results of such treatment (solubility or possible changes on the surface) of the Fe nanowires were measured by IR (infrared spectroscopy), ASA (atomic absorption spectroscopy), TEM (transmission electron microscopy), XRD (X-ray diffraction) and DSC (differential scanning calorimetry) methods.

► Stability of Fe nanowires in environmental solutions was tested.
► The most aggressive and the least aggressive solutions were determined.
► The influence of different solutions on nanowires core were found out.
