Nanoparticles of copper and copper oxides: Synthesis and Determination of antibacterial activity
Abstract In the present study, nanoparticles of copper and copper oxides were synthesized and their antibacterial activity was evaluated and compared with silver nanoparticles. The nanoparticles were synthesized using facile chemical reactions, and then characterized using field emission scanning microscopy. The nanoparticles were stable for at least two weeks. The...
متن کاملSynthesis and thermal properties of superconducting copper oxides
Aspects of the synthesis and of the characterization of the thermochemical properties of high-T, mixed copper oxides, in particular of the Y-Ba-Cu-0 system and of the Bi-Ca-Sr-Cu-0 system are discussed. Related studies are based on conventional thermoanalytical tools such as thermogravimetry and differential thermal analysis. Facilities for the determination of the partial pressures of the gase...
متن کاملHighly efficient synthesis of [60]fullerene oxides by plasma jet
Atmospheric pressure nonequilibrium plasma jet has been applied to the synthesis of [60]fullerene oxides (C60On) for the first time. C60O and C60O2 were produced and isolated in high yields up to 44% and 21%, respectively. The structural assignment of C60O was confirmed by comparison with the reported spectroscopic data. Theoretical calculations of 13C NMR chemical shifts for eight isomers of C...
متن کاملMicrowave plasma synthesis of lanthanide zirconates from microwave transparent oxides.
Lanthanide zirconate phases Ln(2)Zr(2)O(7) and Ln(4)Zr(3)O(12) (Ln = Y, La, Gd, Dy, Ho, Yb) have been prepared using a microwave induced plasma methodology, which allows rapid synthesis using materials which do not couple directly with microwaves at room temperature. We describe the measurement of heating profiles of the precursor binary metal oxides which can be used to identify conditions con...
متن کاملorthorhombic phase of copper - oxides
A microscopical theory of electronic spectrum and superconductivity is formulated within the two-dimensional anisotropic t − J model with tx = ty and Jx = Jy. Renormalization of electronic spectrum and superconductivity mediated by spin-fluctuations are investigated within the Eliashberg equation in the weak coupling approximation. The gap function has d + s symmetry with the extended s-wave co...
