“…27 It seems the PANI nanoparticles are decorated on the outside surface of MnO 2 nanorods with a fibrous structure prepared by in situ polymerization method. 27,28 Further this morphology could help the efficient transit of charge carriers and will be discussed in the future sections of this article. FT-IR study.-Figure 5 shows the FTIR spectra of the PANI/MnO 2 nanocomposite.The peaks that are less than 1000 cm −1 are attributed to the Mn-O-Mn vibrations.…”

Polyaniline/Manganese dioxide (PANI/MnO2) nanocomposite has been successfully prepared by in situ polymerization method. The X-ray Diffraction (XRD) data confirm the formation of PANI/MnO2 nanocomposites. Fourier Transform Infrared (FT-IR) spectroscopy confirms the vibrationsdominant by metal oxide and polymer in the complex format. The Scanning Electron Microscope (SEM) shows that these nanocomposites exhibits nano rods like morphologies. The optical properties were studied by UV–visible Spectroscopy and the optical band gaps were estimated to be around 1.62 eV. Also this composite follow indirect allowed transition. Cyclic Voltammetry (CV) of this composites were also studied, and from this data the specific capacitance (Cp), energy density (Ed), power density (Pd) and charge retention were also calculated. Additionally, from CV data, the energy levels such as the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) were also determined. A supercapacitor of this understudy material was designed and it’s charging and discharging under different conditions (like under the exposure of different wavelengths of light and various intensities of static magnetic fields)were also studied and explained. The preliminary designed supercapacitor shows good charge retention capacity. The specific capacitance of this capacitor remainsaround 463 Fg−1 at 200 cycles. Besides this, a planner diode of this composite was also fabricated and this diode was tested for current-voltage (IV) characteristics under various conditions like under exposure to photons of various wavelengths and in presence of different static magnetic fields.The various parameters related with this diode were analyzed and studied. The dielectric studies of this material were studied. The current materials could be explored as a good candidate for modern energy storage and optoelectronics applications.

The pathogen‐based diseases are prime concern for modern society. Some oxide‐based nanomaterials have been found to show promising antimicrobial activities. However, the industrial synthesis of these oxide materials are harmful to environment. Zinc oxide nano‐flakes were prepared using corn silk (Zea mays) extract. The material was characterized by spectral and microscopic techniques. XRD data shows rutile structure and nano‐crystal size of 36.15 nm. SEM indicates morphology consisting of nano size particles with porous structure. EDX confirms presence of Zn and O. UV‐Vis data shows band gap of 3.62 eV. On excitation, PL exhibits a variety of emission bands in visible spectrum. Dielectric properties suggest the dielectric constant has a well‐dispersed real and imaginary portion. The ZnO NFs were subjected to antimicrobial activities (in dark and under white light) against various strains like E. coli, K. pneumonia and S. aureus. The light induced antibacterial activity is slightly higher as compared to that in dark. Best part of this study is that minimum concentration of ZnO can be used in presence of light thereby reducing the toxicity to the environment due to these metal oxides. Based on the observed results, this material could be used as multi‐dimensional functional material in day‐to‐day life.
