Raw SEM images for paper 'Active transfer learning assisted sustainable electrohydrodynamic atomization with gamma-valerolactone'These nanoparticle have been prepared with a novel sustainable solvent gamma-valerolactone. Different folders and expeirment numbers were conducted with various atomization processing parameters. These data were collected for the purpose of estabilishing a machine learning model for the prediction of atomization product properties of this new solvent. The SEM images have been acquired with Zeiss Gemini SEM under SE2 detector.
