Automated chemical synthesis in the aerosol phase

This page presents the computational imaging results for analyzing aerosol reactivity outcomes from our automated synthesis experiments.

Image visualisation in different colour spaces

Microscope images are analyzed in RGB, HSV, and LAB color spaces to understand droplet formation and chemical reactions. Each color space provides different insights into the reaction outcomes.
