D., Synthesis and characterization of Mn-doped ZnO nanocrystals, J.

Abstract:
TiO2 nanofibers were synthesized using electrospinning [Jamil et al Ceramics International 38 (2012) 2437–2441]. The nanofibers were polycrystalline and porous in nature having average diameter and length of ~150 nm and 200 µm, respectively. Fig. 1 (a) and (b) shows scanning electron microscope (SEM) and transmission electron microscope (TEM) image of TiO2 nanofibers, respectively. The bandgap of the nanofibers lies in optical range ˃ 3.2eV. Which showed relatively low photocatalytic degradation of toxic textile dyes (Fig. 2). To improve it photocatalytic activity we embedded Mn0.5Co0.5Fe2O4 nanoparticles into TiO2 nanofibers. Which showed improved photocatalytic activity for the degradation of toxic organic compound (Fig. 2). We are now investigating the effect of photocatalytic water splitting for hydrogen evolution. It is expected that these heterostructure nanofibers will show improve photocatalytic activity for hydrogen evolution via water splitting.

Title of Talk: SYNTHESIS OF EUROPIUM DOPED HYDROXYAPATITE NANOPARTICLES FOR CELL LABELING

Abstract:
In this study, both chemical precipitation and mechanical milling techniques were used to synthesize either Fe nano-particles or mixed Fe, Al, Ti nano-composites using iron rich industry waste such as red mud as precursor. Further heat treatment of chemically and mechanically treated red mud lead to in-situ formation of nano-sized particles or composites. Such metal matrix composites have attracted much attention due to its use as structural materials in automotive and transportation industries because of their low density, high specific modulus, strength, wear and corrosion resistance. The present work used iron and titanium rich fraction of chemically treated iron rich industrial rejects for preparation of value added Fe and Fe-Al-Ti nano-material. The structural transformation behavior from bulk to nano at different temperatures has been assessed by XRD and SEM. SEM results clearly show that chemical precipitation produced Fe nano-crystals that were obtained after using Fe enriched chemically treated red mud residue whereas mixed nano-material were obtained after mechanical milling.

Extrusion of Rigid PVC Foam with Nanoclay: Synthesis …


Tensile properties of plain and nanoclay reinforced epoxy matrix ..

Abstract:
Heterogeneous photo-catalysis is an advanced oxidation process (PAO), which has been the subject of numerous studies and applications, particularly using the commercial oxide of TiO2 (P25, Evonik). Zinc oxide (ZnO) has often been considered a valid alternative to TiO2 due to its good opto-electronic, catalytic and photochemical characteristics along with its low cost. In order to improve the photocatalytic performance of ZnO for practical applications, various types of synthetic approaches have been developed, including, among others, the hydrothermal / solvothermal growth method, sol-gel method, ultrasonic assisted method, deposition chemistry in vapor phase, etc. with the aim of preparing ZnO particles with different sizes and morphologies. However, all of these methods require relatively severe reaction conditions such as high temperature, sophisticated techniques, high purity of gases, adjustable gas flow, expensive raw materials, etc. Therefore, it is important to find a simple and cost-effective method for the synthesis of crystalline nano-particles of ZnO. For this reason, in the present work, the ZnO has been synthesized by three different procedures: conventional aqueous precipitation method, hydrothermal method (H) and microwave assisted method (MW). In all three processes, the same material is obtained, hydrocincite [Zn5(CO3) 2(OH)6], which evolves to crystalline ZnO after calcination thermal treatments. We investigated the effect of the calcination temperature, at the same time (2 h), on the optical, textural and structural properties. Photo-catalytic studies were performed using two selected substrates, Methyl Orange and Phenol, as toxic model substrates (one colorant and the other transparent). The catalysts prepared were characterized by several techniques: DRX, SBET, FE-SEM, TEM and UV-Vis (in diffuse reflectance mode).From the results of XRD, it has been possible to establish that a minimum difference between the relative intensities of exposed faces (I100 and I002) is a crucial factor to obtain good photocatalytic properties. This minimum difference is achieved, in our cases by thermal treatments of calcination at 400ºC, 2 h. When this temperature is chosen, there is no appreciable variation between the photocatalytic activities of the oxides of zinc obtained by the three processes, and there are small differences depending on the nature of the substrate chosen, which can be attributed to the textural differences between the oxides. In any case, the obtained zinc oxides show, for each substrate, photo-catalytic activities in the UV that are superior to those presented by the widely used commercial oxide TiO2 (P25) used as reference.

Nanocomposites: synthesis, structure, properties …

Abstract:
Novel polyacrylonitrile (PAN) grafted sepiolite nanohybrids were synthesized via emulsion graft polymerization. The influence of synthesis parameters on the degree of grafting was studied by varying the concentrations of monomer, initiator and surfactant. The nitrile groups of PAN were chemically modified into amidoxime. Both the grafting and amidoxime percentages were determined gravimetrically and maximum grafting of 373% was achieved at 5% acrylonitrile, 1% surfactant and 0.1% initiator concentrations. The presence of vibration at 2242 cm-1 in Fourier transform infrared (FT-IR) spectrum and x-ray diffraction (XRD) reflection at 2θ = 16.9° (010) confirmed the grafting of PAN chains onto modified sepiolite. XRD patterns also indicated a decrease in crystallinity of sepiolite and appearance of new amorphous region in grafted nanocomposites. The morphological changes of sepiolite during silanization and grafting of PAN is also confirmed by field emission scanning electron microscope (FESEM). Transmission electron microscope (TEM) images clearly showed the shortening of fibers after silanization of sepiolite and the same were involved in heterogeneous nucleation in micelles. These developed amidoxime grafted sepiolite nanohybrids can be used as adsorbent for the metal recovery.
