Terbium Removal from Aqueous Solutions Using a InO Nanoadsorbent and Biomass.

Terbium is a rare-earth element with critical importance for industry. Two adsorbents of different origin, InO nanoparticles and the biological sorbent , were applied for terbium removal from aqueous solutions. Several analytical techniques, including X-ray diffraction, Fourier-transform infrared spectroscopy, and scanning electron microscopy, were employed to characterize the adsorbents.

A Novel Ibuprofen Derivative and Its Complexes: Physicochemical Characterization, DFT Modeling, Docking, In Vitro Anti-Inflammatory Studies, and DNA Interaction.

A novel derivative of ibuprofen and salicylaldehyde N'-(4-hydroxybenzylidene)-2-(4-isobutylphenyl) propane hydrazide (HL) was synthesized, followed by its complexation with Cu, Ni, Co, Gd, and Sm. The compounds obtained were characterized by HNMR, mass spectrometry, UV-Vis spectroscopy, FT-IR spectroscopy, thermal analysis (DTA and TGA), conductivity measurements, and magnetic susceptibility measurements. The results indicate that the complexes formed were [Cu(L)(HO)]Cl·2HO, [Ni(L)], [Co(L)]·HO, [Gd(L)(HO)](NO)·2HO and [Sm(L)(HO)](NO)·2HO.
