Extended Data Fig. 4: Hydrogen evolution rates for candidate bioderived sacrificial hole scavengers.
From: A mobile robotic chemist

Results of a robotic screen for sacrificial hole scavengers using the mobile robot workflow. Of the 30 bioderived molecules trialed, only cysteine was found to compete with the petrochemical amine, triethanolamine. Scavengers are labelled with the concentration of the stock solution that was used (5 ml volume; 5 mg P10). The error bars show the standard deviation.
