Dataset for: Defining the sonochemical threshold for phase-pure Fe3O4 nanoparticle synthesis

Folder Structure and Contents Raw_data-FTIR: Contains FTIR spectra of as-synthesized nanoparticles and controls Files are provided in .dpt and .ASC formats, structured as XY columns (wavenumber (cm-1), Intensity (counts)). Raw_data-XRD: Contains XY data for the XRD patterns of the nanoparticle samples. Files are provided in .dat format, structured as XY columns (2Theta (°), Intensity (counts)). Raw_data-TEM1-5: Contains raw nanoparticle micrographs in .ser format. These files preserve full metadata and can be viewed using ImageJ (with TIA Reader plugin), Gatan DigitalMicrograph. Raw_data-MFH: Contains raw temperature vs. time profile data for Magnetic Fluid Hyperthermia assessments. The .txt files include the experimental time-series data along with instrumental parameters and applied magnetic field settings. Raw_data-UV-Vis: Contains the absorption spetra used for iron quantification via the thiocyanate colorimetric method. Files are provided in .csv format, structured as XY columns (Wavelength (nm), Absorbance (A.U.)) Raw_data-Synthesis: Contains two demonstration videos illustrating the sonochemical process. Example of incomplete Fe(OH)2 conversion in S022-UP folder. Example of complete Fe(OH)2 conversion in S027-UP folder.
