One step hydrothermal green approach of CuO/Ag nanocomposites: analysis of structural, biological activities

WITHDRAWN: A facile synthesis of MgFe2O4/ZnS heterojunction with effectively enhanced visible light photocatalytic activity for degradation of methylene blue and crystal violet dyes

“…05-0566)[11,12]. The average crystallite size (D) of the prepared materials was evaluated by Scherrer formula[13][14][15].D = 0.94λ/β cos θWhere, λ signi es the wavelength of Cu Kα radiation (1.5405Ǻ), β and θ are full width at half maximum of broadened characteristic peaks and Bragg diffraction angle, respectively. The average particle size of assynthesized MgFe 2 O 4, ZnS and MgFe 2 O 4 /ZnS NCs was determined to be 33 nm, 47 nm, and 55 nm.…”

Synthesis, optimization and characterization of silver nanoparticles using the catkin extract of Piper longum for bactericidal effect against food-borne pathogens via conventional and mathematical approaches

“…Derivatives of phenols such as tannins are identified to be more efficient in reduction of silver salts into silver nanoparticles. Concentration of reducing agents and the silver salt used, pH, temperature and duration of incubation are critical parameters for the biosynthesis to occur [79] , [80] , [81] , [82] , [83] , [84] . Therefore, the phytochemicals identified by GC-MS, in this study, could be possible reductants and/or encapsulates on the nanoparticles from the catkin extract.…”

Green synthesis of copper nanoparticles from an extract ofJatropha curcasleaves: characterization, optical properties, CT-DNA binding and photocatalytic activity

“…19 Fe, Cu, Zn and Ag nanoparticles have been synthesised using biological sources and have been reported in potential applications such as for antimicrobials, photocatalytic activity etc. [20][21][22][23][24][25][26] However, the multifunctional activity of green-synthesised nanoparticles is not reported in any of the previous research. Therefore, we focused on the multifunctional activity of JC-CuNPs.…”
