“…The chemical shifts were distinguished in portions per million (ppm). In the free ligand, H2L 2 spectrum, the singlet signals at δ 11.32, 8.56, 8.41 and 8.23 ppm were attributed to carboxylic, phenolic or NH and azomethine protons, respectively, while the multiplet that appeared at δ 6.70-7.59 ppm is associated with aromatic protons [27,28]. Comparing the 1 H NMR data of the free ligand and its complexes explains the coordination method among the ligand and its metal ions.…”

The current research focused on the Schiff base ligand (S,E)-2-((2-hydroxy-3-methoxy- benzylidene)amino)-3-(1H-imidazol-4-yl)propanoic acid which synthesis by reacting L-histidine and 2-hydroxy-3-methoxy-benzaldehyde. Its complexes with Ce(III) and Fe(III) both in bulk and nano size were also synthesized. The ligand and its metal complexes were characterized by various physicochemical methods such as FT-IR, 1H NMR, 13C NMR, electronic spectra, XRD, TGA, and SEM. The synthesized ligand and its metal complexes were screened against different fungi. It was found from the results that the cerium nano complex shows a potent antifungal activity for indoor uses as wallpapers.

“…The in vitro antibacterial activity of the RBEE was evaluated using the well-diffusion method (Heatley et al, 1944;Habila et al 2021) in DMSO (dimethyl sulfoxide) (35mg/mL for bacteria and 100 mg/mL for fungi). The microbial strains investigated include one Grampositive bacteria (Staphylococcus aureus ATCC 43300) and two Gram negative bacteria (Citrobacter freundii ATCC 8090 and Proteus vulgaris ATCC 29905).…”

The ethanol extract from aerial parts of Ranunculus were investigated for its chemical composition by LC-ESI-MS/MS technique, which allowed to identify a series of glycosylated flavonoids and one phenolic acid. RBEE extract showed acetyl-cholinesterase inhibition higher than the reference compound Galantamine at a concentrationof 200 µg/mL. A moderate antibacterial activity of the extract was also obtained against Staphylococcus aureusATCC43300, Citrobacter freundii ATCC8090, and Proteus vulgaris ATCC29905 at a concentration 100 µg. Additionally, a good reduction in plasma coagulation time at 200 μL was also observed for RBEE.

“…The NMR data were reported in parts per million (ppm), and all exchangeable protons were determined by addition of D2O. 1 H NMR spectrum of the free ligand, HL displayed SO2NH proton as a singlet signal at δ 10.97 ppm (exchangeable with D2O) [25]. The multiplet observed in the range of δ 6.53-7.66 ppm region belong to aromatic and heterocyclic protons [20].…”

Electrolysis (ED) is a modern technology for separating pollutants using membranes located in an electric field and has therefore been used in industrial wastewater treatment. The cornerstone of an ED cell is a stack of membranes whose planar plate is composed of cation (CM) and anion (AM) selective membranes. To investigate design requirements such as limiting current density (LCD), current efficiency and membrane resistance by laboratory experimental scale using an ED cell with electrodes, stainless steel 316 [cathode (-) and anode (+)],value of pH equal 6.8 and low voltage supply energy of 24.8 V is installed to remove about 100mg/L for each metal (Iron, Manganese, Nickel, Copper, Zinc, Lead, and Cadmium) ions out of solution of salts. The modified membranes and electrodes to upgrade its durability and conductivity, the recycle flow was 90 and 34 L/hr for concentrate and product, respectively, which are 25 and 9.4 ml/s and with consumed 7 to 11 kWh/m 3 for a continuous operation. For industrial wastewater; the results are obtained a best and encouraging specific with removal efficiency (up to 91.87%) during the 4 hr operating time. The result of removing heavy metal ions was 1.521, 0.96, 0.123, 1.41, 0.94, 0.12 and 0.097 mg/L as initial concentrated and after passing through ED cell became finial concentration 0.23, 0.11, 0.01, 0.22, 0.14, 0.02 and 0.014 with removal efficiency 84.88, 88.54, 91.87, 84.40, 85.11, 83.33 and 85.57% for heavy metal ions under study respectively. The next is being acted on large scale for long operating system.
