Facile Synthesis, X-ray structure of new Multi-Substituted Aryl Imidazole ligand, Biological Screening and DNA binding of itsCr(III), Fe(III) and Cu(II) coordination  compounds as potential antibiotic and anticancer drugs
A simple highly adjustable and effective synthesis of aryl imidazole ligand HL namely (2‐(1‐butyl‐4,5-diphenyl‐1H‐imidazol‐2‐yl)(4-bromophenol) was discussed where it was prepared by cyclo condensation of 5-Bromo-2-hydroxybenzaldehyde, benzil and Butan-1-amine. Three new Cr(III), Fe(III) and Cu(II) complexes of aryle imidazole ligand were synthesized. The multi-substituted aryl imidazole ligand (HL) and its complexes were characterized by using physicochemical and IR and electronic spectral ... Read more

Kinetic study of humic acid adsorption onto smectite: The role of individual and blend background electrolyte
Many factors can affect the natural organic matter adsorption on clay, such as pH and ionic strength. Blended background electrolyte could be causing better simulation to natural effects. Therefore, kinetic study of humic acid (HA) adsorption onto smectite has been studied under various conditions. Impact of pH and individual and blend background electrolyte with different ionic strength concentration on the ... Read more

Impact of Co2+ substitution on microstructure and magnetic properties of CoxZn1-xFe2O4 nanoparticles
In the present work, we synthesized CoxZn1-xFe2O4 spinel ferrite nanoparticles (x= 0, 0.1, 0.2, 0.3 and 0.4) via the precipitation and hydrothermal-joint method. Structural parameters were cross-verified using X-ray powder diffraction (XRPD) and electron microscopy-based techniques. The magnetic parameters were determined by means of vibrating sample magnetometry. The assynthesized CoxZn1-xFe2O4 nanoparticles exhibit high phase purity with a single-phase cubic spineltype ...

A robust in vitro Anticancerc, Antioxidant and Antimicrobial Agents Based on New Metal-Azomethine Chelates Incorporating Ag(I),  VO(II)  and Pd(II) Cations: Probing the Aspects of DNA Interaction
A novel azomethine ligand (HNAP) [HNAP = 1-(Pyridin-3-yliminomethyl)-naphthalen-2-ol] and its Ag(I), Pd(II) and VO(II) chelates have been synthesized and structurally inspected using a wide range of spectroscopic and analytical tools, including infra-red (IR), ultraviolet-visible (UV-Vis) and 1H NMR spectroscopy techniques, CHN analysis, molar conductance, magnetic susceptibility, and thermogravimetric analysis. The molar conductance measurements reveal that the chelates are non-electrolytes. The ... Read more

Synthesis and Characterization of New Cr(III), Fe(III) and Cu(II) Complexes Incorporating Multi-Substituted Aryl Imidazole Ligand: Structural, DFT, DNA Binding, and Biological Implications
Designing new metal-based molecular antibiotics is an efficient approach to overcome the growing threat of antimicrobial resistance. In this paper, novel Cr(III), Fe(III) and Cu(II) complexes comprising substituted aryl imidazole ligand (MSEB), namely (2-(1-(2-hydroxyethyl)-4,5-diphenyl-1H-imidazole-2-yl)(4-bromophenol)) have been synthesized and characterized using infra-red (IR), ultraviolet-visible (UV-Vis) and 1H, 13C NMR spectroscopic techniques, together with elemental (CHN) and thermogravimetric analyses, molar conductance, and ...
