The use of liquid ion exchangers enables selective separations of, e.g., metal ions or acids, by reactive extraction processes. For the simulation of countercurrent column performance, three major points have to be tackled: The first step is a description of reactive equilibria, based on Gibbs...
Copper ions differ from other thiol reactive metal ions in their effects on the concentration and redox status of thiols in HeLa cell cultures Ions of metals such as copper, mercury, silver and cadmium are known to exhibit a high affinity for thiol groups and may therefore severely disturb many...
A computational modeling framework is described for the analysis of multi-phase flows in reactive porous media targeted at the metals recovery through stockpile leaching and in environmental recovery processes. These systems involve a complex suite of interacting fluid, thermal and chemical reaction physic...
In 2002, Šafařikova and Šafařik tested the applicability of the magnetic solid phase extraction procedure for high volumes of urine samples. For this purpose, they have fabricated a reactive copper phthalocyanine dye-immobilized magnetite particles for the separation and preconcentration of cryst...
This study presents a novel method for nanocellulose production using [Bmim]Cl as a green solvent, with enhanced hydrolysis efficiency achieved through the addition of a transition metal complex as a catalyst. The redox capability of the transition metal

However, in cancer cells with an innately high level of intracellular ROS due to rapid metabolism and higher lipid peroxidation, lower levels of antioxidant enzymes, and the higher laves of reactive metals (e.g., Fe (III) and Cu(II), CARs, including astaxanthin, fucoxanthin, β-carotene, ...
