Synthesis, Characterization and Antibacterial Activity of Mono- and Binuclear Co(II) and Cr(III) Mixed-Ligand Complexes Derived from α-Amino Acid and 1,10- Phenanthroline with 1,3-Diaminopropan as a Spacer
Abstract: Mixed-ligand complexes of Co(II) and Cr(III) ions were synthesized from the reaction of metals chloride salts with α-amino acid (H2L1) as a primary ligand and 1,10-phenanthroline (L2) as secondary ligand. The ligand 2-(benzo[d]thiazol-2-ylamino)-2-(2-hydroxynaphthalen-1-yl) acetic acid (H2L1) has been synthesized from the condensation reaction of inobenzothiazol with 2-hydroxy-1-naphthaldehyde in the presence of HCN as three components–one pot reaction. H2L1 considered as a tridentate chelater of ONO-coordination binding type toward the metals, …

Complex Space-Time and the Structure of Relativistic Quantum Theory
Abstract: Relativistic quantum mechanics was developed to reconcile the principles of quantum mechanics with Einstein’s theory of relativity. Despite its success in describing high-energy particles, the theory continues to face unresolved conceptual and mathematical difficulties, particularly in relation to the nature of time, causality, and relativistic consistency. In recent years, the idea of extending space-time into the complex domain has emerged as a useful and potentially meaningful approach to these problems. …

Tailoring The Electrochemical Interface of Graphene–Gd₂O₃ Nanocomposites for Advanced Energy Storage
Abstract: Graphene–Gd₂O₃ nanocomposites were synthesized by incorporating varying concentrations of reduced graphene oxide (rGO) into Gd₂O₃ using a straightforward room-temperature solution method. The composites were analyzed using various distinct characterization techniques, including X-ray diffraction (XRD), Fourier-transform infrared (FTIR) spectroscopy, Raman spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). Electrochemical measurements, particularly cyclic voltammetry (CV), demonstrated that the incorporation of graphene significantly enhanced the electrochemical performance …
