    Dataset for publication ``A bin-resolved statistical framework for comparing particle size distributions''
    (Technische Universität Bergakademie Freiberg, 2026-07-23) Mitra, Rahul
    This dataset accompanies the study introducing the Difference Significance Profile (DSP), a statistically rigorous framework for bin-resolved comparison of particle size distributions (PSDs). It contains particle-level size measurements obtained by in-line SOPAT imaging of spray-dried alumina powders, together with all processed data required to reproduce the statistical analyses presented in the associated publication. The repository includes raw particle-size data, common binned PSDs, probability differences, bin-wise DSP statistics, bootstrap calibration results, covariance matrices, and comparison-level summary statistics for two experimental scenarios: (i) powders produced under different spray-drying temperatures (120 °C and 145 °C) and (ii) repeated experiments under identical conditions (120 °C) to assess repeatability. Additionally, mercury intrusion porosimetry measurements for the two temperature conditions are provided to support the physical interpretation of the observed PSD differences. The dataset enables complete reproduction of the DSP analysis, facilitates benchmarking against alternative PSD comparison methods, and provides a reusable resource for statistical analysis of particle size distributions in particle technology and related fields.

    Granule size and shape data from SOPAT for publication "Impact of Feed Rate and Binder Concentration on the Morphology of Spray Dried Alumina-Polymer Nano-composites"
    (Technische Universität Bergakademie Freiberg, 2025-04-24) Mitra, Rahul
    This dataset comprises in-line experimental SOPAT data from spray drying investigations of alumina and polyvinylpyrrolidone-30 composite granules. The spray drying process outcomes are documented through inline optical images of dried granules obtained via a SOPAT in-line imaging system providing maximum and minimum Feret diameter and aspect ratio information.

    Micro-CT data for SPP 2364 "Model-based control of spray synthesis of structured granules with specified properties using transfer functions derived by multivariate stochastic models and machine learning"
    (Technische Universität Bergakademie Freiberg, 2025-04-23) Mitra, Rahul
    The data set comprises the micro-CT data from the 1st funding period of the SPP 2364, project number 504580586. The data published here contains the raw, reconstructed micro-CT images of the two spray dried samples (at two different feed rates) tested. The scans were done using the Zeiss Xradia Versa 510.
