Summary: This study investigates the impact of incorporating triethylenetetramine (TETA) into zeolitic imidazolate framework (ZIF-8) on CO2 adsorption capacity. The results show that TETA-impregnated ZIF-8 samples have slightly higher CO2 adsorption capacity than ZIF-8 at pressures lower than 2.5 bars, but as the pressure increases, ZIF-8 samples exhibit higher CO2 adsorption capacity compared to TETA-impregnated ZIF-8 samples.

Summary: In this study, a composite adsorbent material, SLS/CS@ZIF-8, was synthesized by introducing sodium lignosulfonate into chitosan foams (CS-FM) and loading ZIF-8 onto the resulting foams (SLS/CS-FM) to effectively remove CIP from water. The maximum adsorption capacity of SLS/CS@ZIF-8 was found to be 413 mg/g, surpassing most previously reported adsorbents. The adsorption process followed the pseudosecond-order kinetic model and Langmuir isothermal model, and involved electrostatic interactions, hydrogen bonding interactions, and pi-pi interactions.

Summary: This work presents studies on the photochemical transformations of TU and Cys with the addition of Cu(II) or Fe(III) ions. The results show that the oxidation rate of the thiols increases significantly when Cu(II) or Fe(III) ions are added to the system. It has also been found that TU and Cys can form stable complex compounds with the studied metal ions. The oxidation rates of the thiols are found to depend on the radiation intensity and emission spectrum of the irradiation sources.

Summary: The structure and electrochemical properties of zinc(II) complexes with a face-capping ligand have been investigated, revealing the effect of the ligand on bound semiquinonate (SQ) radicals. The substitution pattern of the SQ ring plays a crucial role in determining the fate of the bound SQ radicals. Additionally, the protective pocket formed by the ligand's phenyl substituents is unable to prevent decomposition of SQ radicals with minimal steric bulk, suggesting that substitution of the SQ ring is the main contributor to their stabilization.

Summary: In this article, the synthesis and characterization of copper, nickel, and palladium complexes bound by bidentate ligands derived from ortho-phenylenediamine are described. The complexes contain tunable H-bond donors and their crystal structures reveal intramolecular H-bonding interactions between the ligand scaffolds. Variations in the coordination sphere led to the isolation of the complexes in square-planar or twisted pseudo-tetrahedral geometries. Structural analysis showed that intramolecular H-bonding interactions can be altered by disrupting the bonds between countercations, solvent of crystallization, and ligand scaffold, resulting in changes in the geometry of the complexes. DFT calculations confirmed that Cu complexes prefer twisted geometries while Ni and Pd complexes favor square-planar geometries.
