Structure, Characterization and Anti-Corrosion Activity of the New Metal–Organic Framework [Ag(qox)(4-ab)]

Structure and catalytic activity of a penta-silver supramolecular cluster through hydrogen bonding and 2,2′-bipyridine

“…. .Au [40,41]. The first distance is less than the Ag-Ag distances in metallic silver (2.88 Å) while the second one is quite close to that in metallic silver [42].…”

Synthesis, characterization, molecular modeling, and thermal analyses of bioactive Co(II) and Cu(II) complexes with diacetylmonoxime and different amines

“…T 1 and T 6 showed inhibition of cell viability giving IC 50 values of 24.3 and 17.5 mg mL À1 , respectively, against HEPG2 human cancer cell line (figures 3 and 4). The slight increase in the fraction of live cells at higher concentrations of the complexes in some cases may be attributed to increase of the cells viability due to association of the complexes at higher concentrations which decrease the activity of the metal complexes against the tumor cells [57]. As these results are preliminary, further study on the anti-tumor effects of these compounds is recommended.…”

“…Growth inhibition of 50% (IC 50 ) is calculated as the complex concentrations, which caused a 50% reduction in cell proliferation during the drug incubation [57]. The mean IC 50 is the concentration of drug that reduces cell growth by 50% under the experimental conditions and is the average with scanning electron microscopy from at least three independent determinations.…”

Synthesis, characterization and inhibition effect of new antipyrinyl derivatives on mild steel corrosion in acidic solution

“…The data in Table 2 indicate that the i corr decreases and the inhibition efficiency (P%) increases as the concentration of the inhibitor increases. In fact the slopes of the cathodic (b c ) and anodic (b a ) Tafel lines (Table 2) are slightly changed upon addition of the inhibitors indicating that inhibitors act by simply blocking the available surface area [32]. The ranking of antipyrinyl derivatives remains unchanged; it is as follows: (4) [ (5).…”

“…The diameters of the capacitive loop obtained increase in the presence of inhibitor and are indicative of the degree of inhibition of the corrosion process. The impedance spectra for Nyquist plots were analyzed by fitting to the equivalent circuit model [32,36], which was used to describe an iron/acid interface given in Fig. 6.…”
