“…Hence Ni nanostructures have potential applications in magnetic sensors and memory devices [13]. Many groups have synthesized nickel with different morphologies such as nanoparticles, nanodots, nanowires, nanorods, nanocones and nanofibres by a variety of methods like hydrothermal reduction, electrodeposition and template-based methods [14][15][16][17]. Recently, Cauliflower-like Ni structures via chemical solution method [18], flower-like structures with petals composed of Ni nanotips [19] and hexagonal Ni nanoplatelets via hydrothermal method [20] have been reported.…”

In this work, we prepared new poly(vinyl alcohol) (PVA) based magnetic-pH responsive smart gels comprised of nickel nanoparticles and cross-linked PVA with a pH responsive poly(methyl methacrylic acid) (PMAA) (designated as (PVA-PMAA/Ni-NCGs). We developed a strategy based on the modification of PVA with glycidyl methacrylate (GMA) groups, which has the advantage of being highly efficient in preparing cross-linked PVA with pH responsive polymer chains. The PVA(GMA)-PMAA/Ni-NCGs were characterized by X-ray diffraction, scanning electron microscopy, magnetic measurements and thermogravimetric analysis. We report the relationship between macroscopic properties like the swelling ratio and the network microstructure of PVA(GMA)-PMAA/Ni-NCGs. Swelling in water and drying in air were alternately repeated, in which water was exchanged by new water before each swelling experiment. The PVA(GMA)-PMAA/Ni-NCGs can respond to a magnetic field and the pH changes of an environment. We present an example showing that PVA(GMA)-PMAA/Ni-NCGs can be innovatively exploited as a polymeric material in the application of controlled drug release.

Abstract-In the present work ZnS nanoparticles were synthesized by chemical co-precipitation method at room temperature. The structural properties of ZnS nanoparticles were determined by XRD (X-ray Diffraction), TEM (Tunneling Electron Microscopy) and their optical properties by UV-Visible and PL (Photoluminescence) analyses. XRD analysis showed that sample prepared were the cubic Zinc blende structure with particles' size in the ranges 5nm -12nm. The TEM analysis revealed the formation of ZnS nanoparticles with almost uniform shape and size. In optical characterization the UV_Visible spectra show a large blue shift. In PL analysis, three strong and board emission bands located at 365nm, 400nm and 425nm have been observed. It is well known that the luminescent peak centered at 365nm could be assigned to the UV-excitonic emission and other peaks attributing to the sulfur vacancy.
