[Dataset] Physicochemical Profiling of Dictyota- CaO Mediated Nanoparticles and Nanoscaffolds

A systematic collection of analytical data for Dictyota -fabricated CaO nanoparticles is presented here. X-ray diffraction patterns provide structural information about crystalline phases. UV-visible spectroscopy scans demonstrate optical absorption characteristics. Fourier-transform infrared spectra identify vibrational modes and chemical bonds. Thermogravimetric profiles record mass changes during thermal treatment. Zeta potential values offer information about surface charge properties. Scanning electron micrographs visualize nanoscale surface morphology. The dataset includes primary experimental outputs from each technique. Measurement protocols and instrument configurations are thoroughly documented. Multiple sample replicates confirm consistency across preparations. Background measurements and reference data accompany the main results. This comprehensive dataset enables detailed investigation of biologically synthesized calcium oxide nanostructures.
