Summary: The study investigated DNA complexes with different surfactants using Fourier transform middle infrared spectroscopy, X-ray diffraction and dielectric spectroscopy methods, confirming electrostatic interactions in complex formation. A packing model for the complex molecules, depending on the type of surfactant, was proposed based on SAXS results. The dielectric process in low frequency range was interpreted as oscillation of surfactant ions, similar to ions in pure DNA solutions.

Summary: A series of Cu(I) complexes with bidentate or tetradentate Schiff base ligands containing 1-H-imidazole or pyridine moieties were synthesized and studied using NMR and X-ray spectroscopic techniques. The nature of the heterocycle in the ligands strongly affected the coordination shifts of N-15(imine) in the complexes, which correlated well with the Cu-N-imine bond lengths from single-crystal X-ray diffraction measurements. Variable-temperature NMR experiments revealed a temperature-dependent interconversion in one complex, while Cu K-edge XAS and VtC XES studies suggested the formation of polynuclear oligomers in solid state for complexes with tetradentate imidazole ligands. Incorporation of a Cu(II) analogue into a MOF resulted in discrete, mononuclear complexes in the solid state.

Summary: This study presents the theoretical spectra of some 3d transition metal-phthalocyanines (FePc, NiPc, CuPc, and ZnPc) using Extended X-Ray Absorption Fine Structure (EXAFS). The complexity and rigidity of these compounds make them suitable for testing theoretical strategies in spectrum fitting. Classical and ab initio molecular dynamics trajectories are generated to calculate average spectra for each MPc species. The results show that both types of trajectories produce similar results to the experimental spectra. Spectroscopical information is analyzed based on shells and legs contributions, allowing for comparison with experimental fitting approaches. The lack of multiple backscattering paths due to the rigidity of the chemical motif is discussed.

Summary: Two synthetic nano-TiO2-based materials, aggregated dendritic anatase nano-TiO2 and polycrystalline rutile nano-TiO2 attached to the surface of SiO2, were compared for geo-environmental engineering applications. Results showed both materials demonstrated outstanding capabilities for arsenic removal, but the attached form of TiO2 was more effective under fast groundwater flow condition, while the aggregated form was suitable for high arsenic concentration and low water flow rate. Both materials are cost-effective and can be recovered and reused after regeneration process.

Summary: Electrocatalysis has emerged as a significant research area in fields such as chemical catalysis, environmental research, and chemical engineering. Various catalysts, including transition metal oxide nanoparticles, transition metal nanoparticles, carbon-based nanomaterials, transition metal sulfides, porphyrins, and phthalocyanine molecules, have been used for electrocatalytic reduction of CO2. This review focuses on the CO2 reduction reaction and its products using transition metal sulfide nanomaterials. The main reaction products of CO2 reduction include carbon monoxide, formate/formic acid, methanol, ethanol, methane, and ethene. The type of transition metal-sulfide catalyst used in the reaction determines the products by controlling the intermediate species and reaction pathways. Experimental and computational methods are employed to study the CO2 binding and chemically reduced intermediates, which play a crucial role in the reaction pathways and are discussed in this review.

Summary: As nitrate pollution worsens, the health implications of consuming concentrated nitrate are becoming better understood. Therefore, there is a need for an effective and sustainable method of removing nitrate from water. Electrocatalytic reduction of nitrate (ERN) has been identified as a promising technology, with selective production of nitrogen gas and ammonia, adaptable instrument configurations, and compatibility with renewable energy sources. Electrocatalysts with high selectivity for nitrate reduction are important for drinking water applications, while ammonia-selective catalysts are desirable for resource recovery.

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.
