Novel and highly effective composites of silver and zinc oxide nanoparticles with some transition metal complexes against different microorganisms

Docking Applications For Some Novel Complexes Derived From Quinoline Derivatives

“…Ligand 2 gave a broad and strong band centered at wavenumber 3454 cm -1 which could be attributed to the stretching vibrational motion for O-H group with some inter and/or intra hydrogen bond (Orabi et al, 2018). The obtained result strongly indicated the presence of some tautomerism from the type keto↔enol form.…”

“…The ѵ C=O and ѵ C=N appeared at 1653 and 1517 cm -1 respectively. The IR spectra of the complexes (1-Cu, 1-Ni and 1-Co) strongly enhanced the ligation properties of the C=O and NH 2 groups (Alpert et al, 1970;Nakamoto, 1997;Orabi et al, 2018). The IR spectra of the ligand 4 and their complexes (4-Cu, 4-Ni and 4 Co) revealed the closed similarity with the ligand 2 and their complexes (2-Cu, 2-Ni and 2-Co) (Table 2).…”

“…The conductivity of the formed complexes was measured in DMSO (0.001 M). All the formed complexes gave conductivity in the range 140-179 S (ohm -1 .cm 2 .mol -1 ), which indicates the electrolytic behavior of the complexes (Orabi et al, 2018), which could be formulated generally as [A](NO 3 ) 2 form (Table 1) (Orabi, 2008;Orabi et al, 2001;Tyagi et al, 2015). Generally, the conductivity of the formed complexes has the following order (according the ligand type):…”

“…Magnetic susceptibilities of metal complexes were investigated by the Gouy method which involves weighing a sample of the complex in the presence and absence of a magnetic field and observing the difference in weight. The measurements were carried out using Sherwood Scientific's Magnetic Susceptibility Balance (Dunne, 1967;Figgis et al, 1960;Orabi et al, 2018;Teweldemedhin et al, 1996). The mass magnetic susceptibility (X g ) was calculated by: Χg=LC(R -R o ) / m x 10 9…”

Influence of Inorganic Metal (Ag, Cu) Nanoparticles on Biological Activity and Biochemical Properties of Brassica napus Rhizosphere Soil

“…The environmental effects of using CuNPs are still poorly known, although several papers indicate their use as an agricultural biocide or an additive to anti-lichen fluids affecting the functioning of cell walls and membranes and agents that easily penetrate the interior of bacteria [36][37][38]. Research of the effects of the use of AgNPs on the soil microbiome and its abundance in microorganisms is limited to studies of the impact on plant growth and development [39,40], activity of soil enzymes [41], and numbers of metabolically active soil and rhizosphere microbial communities [42,43].…”
