  • Facile green synthesis of ZnO-CuO nanocomposites using areca catechu leaves and their in vitro antidiabetic and cytotoxicity studies
    U R Shwetha, M S Latha, Virupaxappa S Betageri, G H Pujar, C R Rajith Kumar, et al.
    Advances in Natural Sciences Nanoscience and Nanotechnology, 2021
    The fabrication and diverse applications of mixed oxides have received immense interest due to numerous prospects for better functional performance in tuning their properties compared to the basic metal oxides. Herein, we report synthesis of ZnO-CuO nanocomposites (NCs) using a simple and green route solution combustion method. The as-prepared ZnO-CuO NCs have been characterised through x-ray diffraction (XRD), energy dispersive x-ray (EDX) with scanning electron microscopy (SEM) and transmission electron microscopy (TEM) techniques. The results revealed that as-prepared ZnO-CuO NCs have spherical and rod-shaped structures with an average size between 10 and 30 nm. Further, ZnO-CuO NCs were tested for antidiabetic and anticancer properties. Amylase inhibition and MTT assays were carried out with different concentrations of NCs. The biological results depicted that the as-prepared nanocomposites exhibited significant cytotoxic effects with IC50 value of 13.29 μg mg−1. These observations further showed that the newly synthesised ZnO–CuO NCs are interesting and promising nanomaterials in pharmaceutical and healthcare sector.
  • Nanoparticle surface energy transfer (NSET) in ferroelectric liquid crystal-metallic-silver nanoparticle composites: Effect of dopant concentration on NSET parameters
    T. Vimal, G. H. Pujar, K Agrahari, Sanjeev R. Inamdar, R. Manohar
    Physical Review E, 2021
    In the recent past, the resonance energy transfer studies using metallic nanoparticles has become a matter of quintessence in modern technology, which considerably extends its applications in probing specific biological and chemical processes. In the present study, metallic-silver nanoparticles of 2-4 nm (diameter) capped with hexanethiol ligand are developed and dispersed in ferroelectric liquid crystal (FLC). The morphology of nanoparticles was characterized using HR-TEM and SEM techniques. Furthermore, a systematic study of energy transfer between the host FLC material (as donors) and metallic-silver nanoparticles (as acceptors) has been explored employing steady state and time resolved fluorescence spectroscopic techniques. The nanoparticle based surface energy transfer (NSET) parameters viz., transfer efficiency, transfer rate, and proximity distance between donor and acceptor, have been determined for NSET couples (FLC material-metallic-silver nanoparticle) composites. It is observed that various NSET parameters and quenching efficiency follow a linear dependence on the concentration of metallic-silver nanoparticles in host FLC material. The nonradiative energy transfer and superquenching effect were analyzed with the help of Stern-Volmer plots. The impact of present study about superquenching effect of the silver nanoparticles can be used for sensing applications that require high degree sensitivity.
  • Principal Component Analysis and its Application to Nominal Gross Domestic Product
    Suchitra Hiregowda, GH Pujar, VS Betageri
    Iop Conference Series Materials Science and Engineering, 2020
    Gross Domestic Product refers to financial or market value of all goods and services which are produced within the countries in a specific time duration. As expansive measure of universal domestic production, it functions as a comprehensive record of the country’s economic health. Nominal Gross Domestic Product is the computation of raw data and is more utilitarian comparing national economies on the international market. Some countries have very differing Gross Domestic Product per capita between its regions. A countries region tend to intersect overtime, the discrepancy between the poorer and richer regions is kept over decades in other cases. Here, we considered progress in the nominal Gross Domestic Product per capita across 19 regions in Spain to provide the analysis of progress. This could answer few questions with respect to Nominal Gross Domestic Product viz., Have the regions converged? Which is the spread between regions? The central theme of this article is to answer whether can we make a cluster analysis of the regions after applying principal component analysis?
  • Nonlinear Radiative Heat Transfer of Magnetite(Fe3O4)-Water Nanofluid over Unsteady Stretching Surface with Fluid Particle Suspension
    N Srikantha, M R Krishnamurthy, M M Praveena, K S Onkarappa, K Bharathi, et al.
    Iop Conference Series Materials Science and Engineering, 2020
    The exploration of the magneto hydrodynamics(MHD) flow and nonlinear radiative heat transfer of magnetite Fe3O4 - H2O nanoparticle with fluid particle suspension over an unsteady stretching sheet is the central theme of the present work. The similarity transformations were employed to transfer the governing partial differential equations into ordinary ones prior to solve numerically using Runge - Kutta - Fehlberg-fourth and fifth order method with shooting technique. The variations of the temperature and velocity distribution and coefficients of heat transfer for magnetic parameter, temperature ratio parameter nanoparticle volume fraction, and thermal radiation parameter are discussed graphically. Comparative analysis of reported ones and present work results was presented and found to be in good agreement.
  • Facile Green Synthesis and Characterization of Moringa Oliefera Extract-Capped Silver Nanoparticles (MO-Agnps) and Its Biological Applications
    M S Kiran, M S Latha, Nagappa B Gokavi, G H Pujar, C R Rajith Kumar, et al.
    Iop Conference Series Materials Science and Engineering, 2020
    In the current study, we developed a simple, eco-friendly, quick and economical process to synthesize stable silver nanoparticles (AgNPs) using medicinal herb Moringa oliefera leaves extract. Obtained AgNPs are characterized by spectrophotometrical and microscopic techniques such as UV-Visible spectroscopy, x-ray diffraction (XRD), scanning electron microscopy (SEM) and high resolution transmission electron microscopy (HR-TEM). The study on the in vitro antidiabetic activities displayed that the particles have greater α-amylase inhibition potentials. In addition, exceptional antioxidant activity on 1, 1-Diphenyl-2-picrylhydrazyl (DPPH) is observed. Cytotoxic study against Michigan Cancer Foundation-7 (MCF-7) cell lines displayed significant anticancer activity of AgNPs and hence they can be employed as a promising, cost-reliable and non-toxic strategy for treating these diseases in future.
  • Hydroxy-benzimidazoles as blue-green emitters: Synthesis, structural and DFT studies
    Reshma Sathyanarayana, Vasantha Kumar, G.H. Pujar, Boja Poojary, Madan Kumar Shankar, et al.
    Journal of Photochemistry and Photobiology A Chemistry, 2020
    The new benzimidazole ligands (3a-e) were synthesized using ethyl 4-(butylamino)-3-nitrobenzoate and substituted salicylaldehyde in the presence of sodium dithionite reagent which undergoes “one-pot’’ nitro reductive cyclization. Here benzimidazole moiety acts as an electron-acceptor (A) whereas substituted 2-hydroxyphenyl moiety acts as an electron-donor (D) unit. The molecular structures were characterised by FTIR, 1H NMR, 13C NMR, single crystal XRD and MS analysis. Optoelectronic properties were determined by UV–vis, solution and solid photoluminescence, quantum yield and lifetime. The solvent-dependent absorption and emission were studied using both polar protic and polar aprotic solvents. All the derivatives exhibited ESIPT, especially compound ethyl 1-butyl-2-(3,5-dichloro-2-hydroxyphenyl)-1H-benzo[d]imidazole-5-carboxylate (3e) displayed dual emission in both polar protic and polar aprotic solvents. The compound stability and electrochemical property were determined by thermal gravimetric analysis (TGA) and cyclic voltammetry (CV) respectively. The compounds emit intense blue-green fluorescence with high to moderate quantum yield. Also, these derivatives exhibited a high Stokes shift. The computational studies like Density-Functional Theory (DFT) and Molecular Electrostatic Potential (MEP) were conducted to provide important insights into the structure-property relationships. The crystal packing is stabilized through intermolecular hydrogen bonds (C---H…O) and intermolecular interactions (π… π). The findings of results help in developing novel ligands in the field of organic optoelectronics.
  • Hevea brasiliensis mediated synthesis of nanocellulose: Effect of preparation methods on morphology and properties
    H.S. Onkarappa, G.K. Prakash, G.H. Pujar, C.R. Rajith Kumar, M.S. Latha, et al.
    International Journal of Biological Macromolecules, 2020
    In present research, Hevea brasiliensis (Rubber Wood) converted into cellulose by pre-treatment with NaOH (5%) and NaClO2 (5%). In addition, the cellulose was converted to nanocellulose (NC) using ionic liquid, acid hydrolysis and TEMPO oxidation accompanied by ultra-sonication. The prepared nanocellulose was characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), Fourier transformation infrared spectroscopy (FT-IR). Thermal properties have been studied using thermogravimetric and differential thermal Analysis (TGA/DTA). FT-IR results clearly suggested that the synthetic approaches employed did not alter the principle chemical structure of rubber wood cellulose. SEM and AFM monographs reveal that synthetic approaches affect the morphology/surface topology of prepared nanocellulose. Among the three kinds of NC, NC by TEMPO approach had the largest aspect ratio and superior thermal stability.

    C. R. Rajith Kumar, Virupaxappa S. Betageri, G. Nagaraju, B. P. Suma, M. S. Kiran, et al.
    Journal of Inorganic and Organometallic Polymers and Materials, 2020
    In this work, we have carried out an eco-friendly route for synthesis of zinc oxide nanoparticles (ZnO NPs) via solution combustion method using Calotropis gigantea leaves extract as fuel and Zn(NO 3 ) 2 ·6H 2 O as an oxidizer. The NPs had been characterized employing various analytical techniques namely XRD, SEM, EDAX, HR-TEM with SAED, FT-IR and UV-DRS. XRD confirms crystalline nature with average crystallite size of 31 nm. SEM and HR-TEM images shows that particles are in hexagonal and pyramidal shapes with particles size of 10–50 nm. In FT-IR, characteristic vibrational mode of NPs was observed at 442 cm −1 . The Optical energy band gap was found to be 3.25 eV. Considering practical applications, ZnO NPs exhibited superior photocatalytic activity for degradation of Methylene blue dye. Antibacterial activity of ZnO NPs was screened against Staphylococcus aureus and Escherichia coli bacterial strains. Further, electrochemical performance of developed sensor using NPs was investigated employing electrochemical approaches for quantification of nitrite. Graphic Abstract
