Summary: We synthesized and characterized N-substituted derivatives of 1-cyclopropyl-6,7-difluoro-8-methoxy-4-oxo-1,4-dihydroquinoline-3-carbohydrazide and evaluated their antibacterial activity. We found that modification at the C-3 position decreases the activity of the quinolone scaffold. Docking studies with S. aureus DNA gyrase confirmed the binding interaction of the most active molecule, 5a, and in silico ADME prediction showed that all synthesized compounds met the criteria for being orally active drugs.

Summary: Novel complexes (1-6) of Ni(II), Cu(II), Zn(II), Cd(II), and Pd(II) with the ligand (HL) were synthesized and characterized. The ligand forms neutral thione complexes (2, 4, 5, and 6) with copper(II) chloride, zinc(II) chloride, cadmium(II) chloride, and potassium tetrachloropalladate(II), respectively. Monobasic tridentate complexes (1 and 3) were formed with nickel(II) chloride and copper(II) acetate. Computational studies showed high hyperpolarizability values for the compounds, suggesting their potential use in non-linear optical materials. The metal complexes exhibited stronger antibacterial and antifungal activity compared to the free ligand, with complex 5 showing respectable activity against Gram-positive bacteria and complexes 4 and 5 showing excellent activity against Gram-negative bacteria. Molecular docking revealed higher inhibition efficiency for complexes 1 and 5 compared to the free ligand.

Summary: In this study, the crystal structure of a chlorinated organic compound C12H10ClNO3 was analyzed using X-ray diffraction. The results revealed that the dihydroquinoline moiety in the molecule is not planar, with a dihedral angle of 1.61°. Sheets of molecules parallel to (10 (1) over bar) are formed through intramolecular and intermolecular hydrogen bonds and slipped pi-stacking interactions. The Hirshfeld surface analysis indicated that the most important contributions for the crystal packing are from H···H, H···O, H···Cl, H···C, and C···C interactions. Computational chemistry showed that the stabilization is dominated by the dispersion energy contribution, with C-H···Cl hydrogen-bond energy of -37.4 kJ mol(-1) and C-H···O hydrogen-bond energies of -45.4 and -29.2 kJ mol(-1). Density functional theory (DFT) calculations validated the experimentally determined molecular structure and elucidated the energy gap.

Summary: A new catalyst design, named pseudo-high entropy alloy (HEA), was proposed for high performance water electrolysis. The pseudo-HEAs, which are single-phase alloys of four elements with molar configurational entropy greater than 1.36R, are easier to design and prepare than traditional HEAs with five or more elements. The synthesized FeCoNiMo@C catalyst showed outstanding catalytic efficiency and stability for water electrolysis in alkaline media, achieving ultra-low overpotentials for both hydrogen and oxygen evolution reactions. It also exhibited ultra-low cell voltages and high stability at industrially applicable high current density.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.

Summary: Na-ion batteries (NIBs) have attracted great interest as a potential technology for grid-scale energy storage due to the wide distribution, low cost, and environmental friendliness of sodium resources. However, their implementation is hindered by low rate capability and cycling stability caused by the large ionic size of Na+. In this study, a three-dimensional nanoarchitectured coral-like CoSe2@N-doped carbon (CL-CoSe2@NC) was synthesized, and it exhibited improved sodium storage properties with better electrode kinetics and a stable SEI film.
