<#LINE#>Synthesis, physicochemical investigation and antimicrobial efficacy of Co(II) and Ni(II) chelates with bidentate azomethine ligand<#LINE#>Abubakar A. @Ahmed,Habu N. @Aliyu <#LINE#>1-7<#LINE#>1.ISCA-RJCS-2019-042.pdf<#LINE#>Department of Pure and Applied Chemistry, Faculty of Science, University of Maiduguri, Borno State, Nigeria@Department of Pure and Industrial Chemistry, Faculty of Physical Sciences, Bayero University, Kano, Kano State, Nigeria<#LINE#>30/6/2019<#LINE#>17/4/2020<#LINE#>The azomethine ligand was afforded by condensation reaction of 2-aminobenzoic acid and 4-(N,N-dimethylamino) benzaldehyde in equimolar ratio in an ethanolic medium. Refluxing the Schiff base ligand with CoCl2.6H2O and NiCl2.6H2O yielded the corresponding chelates. The synthesized compounds were investigated by melting point/decomposition temperature determination, solubility test, estimation of water of crystallization, elemental analysis, infrared spectral analysis, magnetic susceptibility and molar conductance measurements. The azomethine ligand and the metal chelates were differently coloured, air stable, non-hygroscopic solids which were found soluble in nearly all of the organic solvents used. The presence of water of hydration was established by heating the complexes to constant weight in an oven. From the high decomposition temperatures, the complexes are suggested to have high thermal stability. The elemental analysis data showed their formation in 1:2 metal - ligand ratio. The obtained molar conductance values of 6.08 and 9.12 ohm-1cm2mol-1 entailed that the chelates are non-electrolytes. The infrared data implied that the azomethine ligand has denticity of 2 with the imine nitrogen atom (C=N) and the deprotonated carboxyl oxygen atom as the coordination sites. The magnetic moment values of 5.44 and 2.93 B.M for the Co(II) and Ni(II) chelates respectively, suggest a paramagnetic phenomenon around a six- coordinate octahedral geometry. The in vitro antibacterial and antifungal sensitivity studies revealed that the metal chelates are more potent against the tested microbes than the uncomplexed ligand.<#LINE#>Anant, P. and Devjani, A.

This investigation intended to assess the possible applicability of these nanocomposites for degradation of 2 organic aqueous dyes-methylene Blue (MB) and Eriochrome Black-T (EBT). The potential application of ZTiO as antimicrobial agents was also investigated using disc diffusion technique against the Gram-negative bacteria, Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae and the Gram-positive Staphylococcus aureus. Antioxidant property of the NPs was established by DPPH radical scavenging technique. The particles show a considerably high bacteriostatic effect towards all the pathogens tested. ZTiO also showed significant cytotoxicity to HeLa breast cancer cells. This proves that the electrochemical synthetic route with its low cost and high efficiency is a competent technique for the large-scale synthesis of heterometal oxide photocatalysts which could potentially be used as effective therapeutic agents.<#LINE#>Royston, E., Ghosh, A., Kofinas, P., Harris, M.T. and Culver, J.N.

Two different regimes of evaporation kinetics were measured experimentally for both solvents. Two distinct rate constants were determined in the range of 10-3 s-1, with overall slower decay for methanol. Total evaporation times for microliter volumes of methanol were measured under container-less acoustic levitation and compared with the evaporation times under container processed normal laboratory conditions. Significant differences in the evaporation time and trend were observed. A typical 4 &mu;L sample of methanol evaporation time increased from 5 minutes to 45 minutes, from normal laboratory conditions to levitation. While a linear trend was observed under normal conditions, a logarithmic trend was observed under levitation. These experiments demonstrate difference in air-liquid interface dynamics due to difference in gravity and contact surface. The extended evaporation time under levitation condition can be utilized to perform and monitor reactions in a droplet which may otherwise be limited due to short droplet lifetime. Such extended lifetimes and microgravity conditions can be used in distinct evnironments, such as crystallization and aggregation of proteins and polymers from solutions. The set up described here can be used as a ground-based microgravity simulation device, which can quickly screen the chemical reactions to limit the payload for more expensive experiments at the international space station.<#LINE#>Lierke, E.

Now-a-days, phytochemical studies on traditional therapeutic plants are acquiring significance. In this aspect a phytochemical screening was carried out on different solvent extracts of the leaves of Pterocarpus santalinus L.f., which is about to get endangered. Research studies on this plant revealed the presence of glycosides, alkaloids, flavonoids, phytosteroids and phenolic compounds. An alkaloid, 5-hydroxy-N,N-dimethyltryptamine was isolated from the methanol (Me) extract by column chromatography. Its structure was confirmed by spectroscopic analysis. Its antimicrobial activity was tested against two pathogenic bacterial strains acquired from contaminated paneer (Indian Cheese) which were identified as Escherichia coli (gram -ve) and Staphylococcus aureus (gram +ve) bacteria. The compound expressed better antimicrobial potential against S.aureus than E.coli, with Maximum Inhibition Zone (MIZ) and Minimum Inhibition Concentration (MIC) values in the range of 1.5-2.0 cm and 0.5-1.0 mg/ml respectively.<#LINE#>Rudd, V.E.

The sample taken from 3 dissimilar places of lake during entire activities of Idol immersion. Comparative study about the concentration of F- with the standard value is done. There is increase in the concentration of fluoride during and after idol immersion activity, but before immersion activity the concentration of fluoride is less than the standard value prescribed by BIS and WHO at some site.<#LINE#>Bhateria, R. and Jain, D.(2016).@Water Quality Assessment of Lake Water.@Sustain.
