Analysis on the effect of ZnO on Carbon nanotube by spray pyrolysis method

Background: ZnO/CNT nanocomposites were prepared using Zinc acetate source materials and with the assistance of copper plate, glycine and sugar solution. The combined behavior between these two materials may give rise to the production of advanced materials with a wide range of applications in electronics and optoelectronics. Methods: The ZnO-CNT nanostructures are successfully prepared by simple perfume spray pyrolysis method on copper substrate. The possible growth mechanism of ZnO-CNT nanocrystals formation by this method has been tried to explore the sensor and optical properties has been demonstrated. Results: The as-synthesized ZnO-CNT nanostructures were characterized using the scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD) pattern measured with Cu Kα radiation. Studies of the morphologies of the ZnO-coated CNTs revealed no significant change in the internal structures single walled graphite sheets and the diameters of the CNTs, but the ZnO appeared to form a layer of thinfilm single crystalline particles attaching to the surface of the nanotubes. The photoluminescence (PL) measurements excited by the 380 nm were done at room temperature. CNTs are easy to be entangled and agglomerate due to their long length and low diffusive mobility in base fluids. Conclusion: The lower mobility was found to occur for the ZnO/CNT composite where a linear sensitivity behavior was measured and it reaches high at the temperature of 200 °C. The samples luminescence is dominated by well-structured ultraviolet band emission and almost no deep level emission was observed, revealing a high optical quality of the produced structures

Bio Synthesis of Zn Doped AgTe with the Help of Allium sativum Peel Powder for Bacterial Results

Composites of Telluride are an extremely rare element most commonly used in combination with other metals to increase their machinability and bioactivity due to its mild toxic nature. Bacteria are currently used to separate a number of elements from their sources, most notably in the bioleaching of Zinc and Silver from their ores. Using biosynthesis method Zn doped AgTe materials were synthesized and characterized by using X-ray Diffractometer, Fourier Transform Spectroscopy and its applications of bacterial results. From structural studies the crystal size was nearly 52 nm, and FTIR spectrometer shows the vibrational frequency of the Zn doped AgTe NPs. Five different bacterial strains both positive and negative and its bioactivity can be measured. The results that were obtained in this research including the Zones of Inhibition (mm) for all the gram positive and gram negative bacteria that were bio assayed in this research.</jats:p

A Study on Heavy Metal Ion Adsorption, Antibacterial and Anticancer Activities of Sawdust Chitosan Activated Carbon

Sawdust-Chitosan Composite beads (SDCCB), a low-cost non-conventional surface modified activated carbon, has been used for the efficient removal of Cu(II) ions from aqueous solutions. Surface morphology of the sample has been characterized by XRD, SEM, EDAX and FTIR analyses. Batch experiments have been conducted spectrophotometrically in order to determine the maximum adsorption capacity and influence of physicochemical parameters. The experimental data has been fitted with various isotherm and kinetic models to predict the conditions for maximum adsorption. The activation parameters evaluated for this adsorption process propose the adsorption mechanism as feasible, spontaneous, endothermic and increased randomness. Also, the antimicrobial and anticancer activities of SDCCB have been screened by disk diffusion method and MTT assay, respectively.</jats:p

Synthesis and Characterization of Indium Tin Oxide with Neem Extract for Antioxidant Applications

Indium tin oxide was prepared by using simple co precipitation method with Neem extract as reducing agent and it was characterized by using X-ray diffractometer, with the applications of antioxidant effect, the prepared sample was directly calcined at 400ºC and then characterized. Morphological studies were analyzed by using Transmission Electron Microscopy and Selective area diffraction pattern. The crystal sizes were calculated and it value is nearly 12 nm. Here, Williamson-Hall (W–H) have been used to investigate the particle size and the intrinsic strain from the XRD peak broadening analysis.</jats:p
