Zinc is an important physiological cation, and its misregulation is implicated in various diseases. It is therefore important to be able to image zinc by non-invasive methods such as Magnetic Resonance Imaging (MRI). In this work, we have successfully synthesized a novel Gd3+-based complex specifically for Zn2+ sensing by MRI.

A multi-analytical approach was used to comprehensively characterize the acid-base, thermal, and surface properties of agri-food processing wastes (i.e., original and pre-treated bergamot, grape and olive pomaces).

- This article discusses the synthesis and structural characterization of chiral Tb(III) and Eu(III) complexes using two different ligands: an enantiopure diamine-based ligand and various hydroxycoumarin ligands.
- Different substituents on the coumarin ligands lead to varying efficiencies in capturing light, which affects the luminescence of the Tb(III) and Eu(III) complexes.
- The study includes theoretical calculations that explain the energy transfer processes in the complexes, alongside insights into how the coumarin ligands influence the chiroptical properties of the Tb(III) complexes.
The room temperature ionic liquid trihexyl(tetradecyl)phosphonium decanoate ([P][Dec]) was employed in the liquid-liquid extraction of Co(II) from hydrochloric acid solutions in the presence of Ni(II). The extraction performance in liquid-liquid separations showed a strong dependence on the acid content of the feed aqueous solution. The best performance in terms of extracted cobalt and selectivity was obtained when the feed contained a HCl concentration above 6 M On the contrary, when the experiment was performed in absence of HCl, a lower extraction and Co/Ni selectivity were obtained.
