“…Similarly, the diameter of nanowires could be controlled by time duration of growth in nutrient solution. Both factors have been well explained in our earlier reports [5][6][7]. Owing the information from earlier results, we have grown ~ 200 nm, ~ 100 nm and ~ 50 nm ZnO nanowires on separate substrate (sample1, sample2, sample3).…”

Here, we report high output voltage generation via oxidized ZnO nanowires. A thorough study has been carried out to observe the behavior of ZnO nanowires under reduced grain size and high temperature conditions. Study has revealed that piezoelectric output voltage generated by ZnO based VING (vertically integrated nanowire generator) has been gradually increased, as the diameter of nanowires is decreased. Secondly, it has also been observed that maximum peak voltage has been further enhanced, if nanowires are oxidized at high temperature. ZnO nanowires ̴ 200 nm have produced maximum peak voltage 2.283 V at room temperature and if oxidized at 200o C then output voltage has been further raised to 2.638 V Having output power density 365.7 mW/cm2, similarly ̴ 100 nm ZnO nanowires have produced maximum voltage of 2.598 V At room temperature and at 200o C the value is elevated to 2.835 V and ̴ 50 nm ZnO nanowires have generated 3.38 V at room temperature and when oxidized at 200o C voltage has been raised to 3.465 V with power density of 511.3 mW/cm2. The values have been significantly improved by our earlier reported values.

“…Currently, this application is being intensively researched on the micro-to nano-scale. 13,14 Common materials with piezoelectricity are based on the working principle that randomly oriented ferroelectric domains are aligned by external forces, such as in the case of toxic PbZrTiO 3 . 15 In contrast, ZnO has attracted much attention since it is a stable and environmentally friendly piezoelectric material.…”

“…It is noteworthy that the heat treatment did not visually alter the morphology of the zinc nanowire structure (Figure ), which confirms thermal decomposition of zinc hydroxy carbonates as a valid reaction route for synthesis of ZnO nanowires . The ZnO nanowires produced by calcination after scCO 2 treatment showed visual resemblance to ZnO nanowires grown by hydrothermal growth …”

Synthetic zinc patina was grown on galvanized steel sheets in supercritical carbon dioxide atmosphere. Different patina compounds were dissolved and quantified using a stepwise immersion and dissolution procedure. The distinct patina components, namely anhydrous zinc carbonate (a dense layer adjacent to metallic zinc) and zinc hydroxy carbonate (nanowires on the surface), were dissolved in glycine solutions, followed by quantification of Zn 2+ in the solutes by X-ray fluorescence. The zinc hydroxy carbonate nanowires were readily glycine soluble, and the anhydrous zinc carbonate showed scarce glycine solubility, which enabled their selective quantification. The amount of the remaining (anhydrous) zinc carbonate after glycine extraction was determined from the glycine-soluble zinc oxide after calcination (heat treatment for 10 minutes at 350°C). The results were verified by scanning electron microscopy imaging and Fourier transform infrared spectroscopy measurements.
