Core-Shell Structured Polyaniline (PANI) – Manganese Dioxide (MnO2) Nanocomposites as an Electrochemical Sensor for Detection of Emamectin Benzoate Supriya Vyasa, , Ashutosh Shukla, Sugam Shivhare, Ratnesh Das, Venkatesh R., , , , and Es Materials and Manufacturing, 2024 The distinctive morphology and novel properties of graphene is quite fascinating as a promising candidate for nanodevices.In this study, we annealed graphene oxide (GO) created through the conventional Hummers method at different temperatures, showcasing the simplicity, safety, and cost-effectiveness of thermal annealing as a superior large-scale fabrication approach.GO's capacity for post-thermal modification broadens its versatile applications in optoelectronics, electronics, nanoelectronics, and more.In this regard, this study investigates the optical, electrical properties, and chemical structure of GO after thermal reduction at temperatures 80C, 120C, 160C, 200C, 240C, and 280C under standard atmospheric pressure.According to the results of the Raman AFM map, the most obvious changes in thickness were observed at 280C, where the average thickness of the reduced GO decreased by 50%.IR spectra indicated that the oxygen-containing functional groups are most stable up to 120C and showed the loss of signals from hydroxyl groups at all other treatment temperatures.The values of the electrical sheet resistance after thermal reduction decreased from 2831.2 to 20.8 M/square, which, in turn, affected the decrease in the interplanar distance from 7.12 to 3.80 .This work demonstrates a novel and effective strategy for fabricating high-performance, rGO films from local raw materials.
High Performance Conducting Nanocomposites Polyaniline (PANI)-CuO with Enhanced Antimicrobial Activity for Biomedical Applications Supriya Vyas, , Ashutosh Shukla, Sugam J Shivhare, Vivekanand S Bagal, Navneeta Upadhyay, , , , and Es Materials and Manufacturing, 2022 The purpose of this research is to develop advance conducting material blended with metal oxides that held both conducting and antimicrobial properties and due to this, applicable in many biomedical fields. The synthesis of nanoparticles of copper oxide (CuO) is performed by the chemical co-precipitation method and the synthesis of pure polyaniline (PANI) and PANI-CuO nanocomposites were performed by using in-situ chemical oxidative synthesis. The structural analysis was carried out by X-ray diffraction (XRD) studies, Fourier transform infrared spectroscopy (FTIR), and Ultraviolet – Visible (UV-Vis) absorption spectrometry. The peaks obtained in spectra validate the fabrication of desired materials. The average particle size of synthesized materials was calculated using the Debye Scherrer formula, which was found in the nanoscale range. The scanning electron microscope (SEM) images explored the morphology of CuO and PANI-CuO composite. The direct current (DC) conductivity measurement of samples was performed by the four-probe method for various temperatures. The values showed an increase of electrical conductivity in the composite as compared to PANI and supported the metallic nature of the composite. The antibacterial activity of composites was performed by disk diffusion method using Bacillus subtilis (Gram + ve bacteria) and Escherichia coli (Gram–ve bacteria) and the results are encouraging.
PAni/Fe3O4nanocomposite coating over cadmium using microwave energy Praveen Kumar Loharkar, Asha Ingle, Sugam Shivhare Aip Conference Proceedings, 2021 Corrosion resistance and wear resistance are important functional characteristics of engineering materials. There is constant research going on in the field of surface engineering to enhance these properties for the use of components in several engineering applications. In addition, the focus of the surface engineering research is to develop novel coating materials and to explore new processes or techniques. Conducting polymer coatings over the metallic surfaces have been extensively studied owing to their corrosion–resistant property. These coatings are primarily obtained using chemical and electrochemical deposition processes. In this paper, an innovative technique based on microwave irradiation is presented for developing a layer of conducting polymer-based nanocomposite on the cadmium substrate. The conducting polymer nanocomposite was prepared in-situ and comprised of a combination of polyaniline (PAni) and Fe3O4. Fe3O4 has been added to enhance the magnetic properties of the conducting polymer. The powdered nanocomposite was spread onto the metal substrate and was subjected to the microwave irradiation which resulted in the coating of the substrate. Characterization of the coated specimen has been carried out using Fourier transform IR (FT-IR) spectroscopy to check the efficacy of microwave processing. The presence of functional groups of polyaniline over the substrate reveals the presence of a thin layer of the nanocomposite. The study has opened up avenues for researchers to explore the energy saving microwave-assisted green processing technique for the coating application.

Field Emission Characteristics of Double Walled TiO2 Nanotubes Girish P. Patil, , Sachin R. Rondiya, Vivekanand S. Bagal, Sugam Shivhare, Russell W. Cross, Nelson Y. Dzade, Sandesh R. Jadkar, Padmakar. G. Chavan, , , , , , , , and Es Materials and Manufacturing, 2021 Double walled TiO2 nanotubes have been synthesized by two probe anodization method on highly pure Titanium (Ti) substrate. FESEM and XRD analyses revealed the morphological and structural properties of the as-synthesized double walled TiO2 nanotubes. Investigation of their field emission characteristics in a planar diode configuration at a base pressure of 1 x 10 mbar has been done. The turn-on field defined for the emission current density of 10 μA/cm is found to be 2.1 V/μm. As the field is increased further to 2.95 V/μm maximum, a current density of 890 μA/cm is achieved. Current-time (I-t) measurement at a preset value of 1 μA emission current for the duration of 3 h demonstrates a robust emission current stability. The observed low turn-on field and stable electron emission makes the double walled TiO2 nanotubes a suitable emitter for various electronics devices applications.
An electrode comprising of graphene nanopowder inserted in an enclosed structure in anodic aluminium oxide coated with PANI by using low temperature hydrothermal process Sugam Shivhare, Supriya Vyas, Vivekanand S. Bagal, Malvika Sharma, Mangla Dave Gautam Aip Conference Proceedings, 2018 Elements like C and its allotropes (Graphene) Sn, Al, Ge, and their compounds are commonly used anodic materials in Li-ion secondary batteries. Out of them Graphene is a promising anodic material for Li-ion batteries as it having high theoretical capacity of 4100 mAh/g as it formed Li4.4C. However, the formation of Li4.4C induces a large volume expansion in the electrode and leads to a rapid drop in capacity. To overcome this problem many experiments and theoretical efforts have been focused on enhancing structural stability of Graphene in electrode. Several methods have been also reported for the fabrication of three-dimensional electrode arrays. In this study, we report an improvement of the cycling performance of graphene nanopowder-based electrode. Graphene nanopowder was inserted and confined on the anodic aluminum oxide coated with polyaniline (PANI) by using a new method. It is confirmed from this study that cycling behavior of the graphene powder electrode can be significantly improved by using the method proposed in this study.
