Synthesis and Characterization of a Hercynite-Supported Copper(II) Complex Based on 1,10-Phenanthroline-5,6-dione and Acetylacetone Building Blocks and Its Catalytic Application in Annulation Reactions.

In the present work, a novel Cu(II) complex containing 10-phenanthroline-5,6-dione (phen-dione) and acetylacetone (acac) was prepared via solid-phase synthesis on silica-modified hercynite magnetic nanoparticles (MNPs). The resulting structure underwent thorough structural analysis using diverse instrumental techniques. The catalytic potential of the synthesized Cu(II) complex was successfully demonstrated in the synthesis of 2-amino-3-cyano-4-chromenes.

LHHW/RSM reaction rate modeling for Co-Mn/SiO nanocatalyst in Fishcher-Tropsch synthesis.

This study aims to assess the kinetics of Fischer-Tropsch (FT) reaction over the cobalt-manganese nanoparticles supported by silica oxide. Nanoparticles were synthesized by the thermal decomposition method using "[Co(NH)CO]MnO" complex and characterized by XRD, TEM, and BET techniques. The kinetics of the process were evaluated using a combination of Langmuir-Hinshelwood-Hougen-Watson (LHHW) and response surface methodology.

Enhanced photocatalytic performance of UiO-66-NH/TiO composite for dye degradation.

In this study, the performance of TiO, ZnO, UiO-66-NH and UiO-66-NH/TiO nanoparticles was investigated.

Synthesis and application of ion-imprinted polymer nanoparticles for the determination of nickel ions.

Novel Ni(II) ion-imprinted polymers (Ni-IIP) nanoparticles were prepared by using Ni(II) ion-1,5-diphenyl carbazide (DPC) complex as the template molecule and methacrylic acid, ethylene glycol dimethacrylate (EGDMA) and 2,2'-azobisisobutyronitrile (AIBN) as the functional monomer, cross-linker and the radical initiator, respectively. The synthesized polymer particles were characterized physically and morphologically by using infrared spectroscopy (IR), thermo gravimetric analysis (TGA), X-ray diffraction (XRD) and scanning electron microscopic (SEM) techniques. Some parameters such as pH, weight of the polymer, adsorption time, elution time, eluent type and eluent volume which affects the efficiency of the polymer were studied.

Interaction of two new mixed ligand copper(II) complexes with DNA probed by thermodynamic and spectroscopic studies.

The DNA binding behavior of [Cu(4,7-dmp)(phen-dione)Cl]Cl (1) and [Cu(2,9-dmp)(phen-dione)Cl]Cl (2) where dmp and phen-dion stand for dimethyl-1,10-phenanthroline and 1,10-phenanthroline-5,6-dion, respectively, was studied with a series of techniques including Viscometry, UV-Vis absorption, circular dichroism and fluorescence spectroscopy.

Thermodynamic parameters, enthalpy and entropy changes were calculated according to Van't Hoff equation, which indicated that both reactions are predominantly enthalpically driven.

DNA binding, DNA cleavage and cytotoxicity studies of a new water soluble copper(II) complex: the effect of ligand shape on the mode of binding.

The interaction of native calf thymus DNA (CT-DNA) with [Cu(ph(2)phen)(phen-dione)Cl]Cl was studied at physiological pH by spectrophotometric, spectrofluorometric, circular dichroism, and viscometric techniques. Considerable hypochromicity and red shift are observed in the UV absorption band of the Cu complex. Binding constants (K(b)) of DNA with the complex were calculated at different temperatures.
