Summary: In this study, we investigated the interaction between the food colorant tartrazine (TZ) and double stranded DNA (dsDNA) using spectroscopic, electrochemical, and computational methods. By combining UV-vis experiments with high-level computational models, we were able to determine the proper binding mode at the molecular scale and explain the experimental optical response due to the complex formation. In addition, we used electrochemical measurements to support the results obtained through UV-vis spectroscopy. Our findings showed that TZ is deeply buried in the DNA, as evidenced by the hypochromic effect observed in the absorption spectra.

Summary: The detection of key ions in environmental samples has become a significant focus in recent years for achieving a cleaner living environment. Bifunctional and multifunctional sensors have emerged as a rapidly advancing field, enabling the detection of metal and cyanide ions. These sensors, composed of simple organic ligands, form coordination compounds with transition metal ions, resulting in detectable visible or fluorescent changes. The sensitivity of these bifunctional sensors relies on the denticity of ligands for metal ions, while for cyanide ions, the sensitivity is independent of the denticity of ligands. This review summarizes the progress made in the field over the last fifteen years (2007-2022), with an emphasis on copper (II) and cyanide ion detection, but also the potential for detecting other metals such as iron, mercury, and cobalt.

Summary: The increased emission of volatile organic compounds (VOCs) and their adverse effects on the environment have led to the development of more economical and sustainable sensing technologies. Ethanol, a member of the VOC family, has harmful effects on human health and the environment. Therefore, there is a high demand for an efficient electrocatalyst for ethanol detection at ambient temperature. In this study, NiO-based sensing material was successfully synthesized by modifying NiO through transition metals doping (8% Cu and 8% Zn) and codoping (4% Cu + 4% Zn). The synthesized catalysts were characterized by various techniques, and it was found that the codoped NiO exhibited better catalytic performance for ethanol detection with a wide linear range and a low detection limit.

Summary: In this study, a heterojunction structure of BiVO4@Fe-TiO2 NRs was developed to improve the photoelectrochemical water splitting efficiency. Structural characterization and morphological studies confirmed the introduction of extrinsic defects and the uniform deposition of core-shell heterostructure. The photoelectrochemical studies showed that BiVO4@0.2 %FeTiO2 exhibited the highest photocurrent density of 1.52 mA/cm2 at 1.23 vs. RHE and 100 mW/cm2 light intensity, significantly higher than BiVO4@undoped TiO2 NRs (0.52 mA/cm2) and pristine TiO2 NRs (45 μA/cm2). These findings highlight the importance of modified host substrates in enhancing PEC performance through improved electron mobility, efficient interfacial charge transfer, and enhanced electron quenching window in type-II heterojunctions.

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.
