Hydrothermal synthesis of Copper nanoparticles, characterization and their biological applications
We report an ecofriendly novel method for copper nanoparticles (CuNPs) synthesis by hydrothermal processes using an activated carboxymethyl gum of locally available medicinal plant Cochlospermum gossypiumas capping agent. The synthesized CuNPs characterized by Ultraviolet - visible Spectroscopy (UV-Vis), Fourier – transform infrared Spectroscopy (FTIR), and Transmission Electron Micros...

متن کاملThe hydrothermal synthesis and X-ray crystal structure of Ag (1)-4, 4"-bipyridine-based coordination polymer
Hydrothermal synthetic were studied for the preparation of coordination polymeric material basedon Ag (I) and 4, 4"-bipy. A polymeric compound [Ag (4, 4'-bipy)].NO3. (I), was prepared andstructurally characterized by single crystal X-ray diffraction. Compound 1(91% yield) was isolatedfrom the reaction of AgNO3 with 4, 41bipy in 2:1 molar ratio. In compound I. each silver (I) islinked to two nit...
متن کاملHYDROTHERMAL SYNTHESIS AND CHARACTERIZATION OF VANADIUM SILICATE MOLECULAR SIEVES WITH ANALCIME, MAGEDIITE AND ZSM-11 STRUCTURE
Vanadium silicates such as V-Al-analcime, V-analcime, V-magediite and V-ZSM-11 were synthesized using vanadium pentoxide or vanadyl sulfates. Vanadium silicates with analcime structure with and without aluminum (V-Al-analcime, V-analcime) were prepared as pure phase by hydrothermal crystallization from a gel with molar composition of (1 SiO2; 0.2 V2O5; 1 Na2O; 0.034 Al2O3; 35.7 H2O) and (1 SiO2...
متن کاملX-Ray Absorption Study of Ti-bearing Silicate Glasses
Ti K-edge XANES spectra have been collected on a series of Ti-bearing silicate glasses with metasilicate and tetrasilicate compositions. The intensity of the preedge feature in these spectra has been found to change with glass composition and varies from 29 to 58% (normalized intensity) suggesting a variation in structural environent around the absorbing atom. The pre-edge peak intensity increa...
