Metal complexes

In this study, the simultaneous determination of Co, Cd, Ni, Cu, and Pb was carried out as a color complex with 4-(2-pyridylazo) resorcinol in an aqueous solution under the assesting of machine learning. A partial least-squares multivariate linear regression and artificial neuron network for the analysis of mixtures of metals were developed. MATLAB is a powerful software machine learning program that was used to support matrix calculations and displays.

This modeling is performed on an experimental data set of complexes, where the metal ions of these complexes include transition ion metals and lanthanide ion metals. We use these models to develop a series of new thiosemicarbazone and their complexes; simultaneously, the complexes are worked out the stability constants from the novel models.

This compound converted to Mannich base which interne illustrated as tridentate ligand of NO2-type. Meanwhile, the organic synthesis of the compounds is not an easy task, especially lactonization; hint naphthafuran-2-one has never been prepared from amino nitrile previously. Selected metal ions of known anticancer activity interacted with the ligand to present novel complexes to figure out the cytotoxicity effect of both organic and inorganic parts against cancer cell line.

Ebook "Electrochemistry of N4 macrocyclic metal complexes - Volume 1: Energy (Second edition)" describes the state of the art regarding molecular catalysts such as MN4 metal complexes, like porphyrins and phthalocyanines. This volume focuses on the particular case of the electrocatalysis of the reduction of O2 for practical applications in fuel cells and air batteries. Indeed, active and stable materials have been developed in the last 5 years where MN4 catalytic systems can be obtained by the pyrolysis of starting materials that do not necessarily involve MN4 complexes.
