A team of scientists at Friedrich-Alexander Universität Erlangen-Nürnberg (FAU) has developed a novel mechanical cleaning method for surfaces on the nanoscale. The technique successfully removes even the tiniest contaminants down to the atomic scale, achieving an unprecedented level of cleanliness. The results of this study led by Prof. Dr. Erdmann Spiecker from the Department of Materials Science at FAU have now been published in the prestigious journal Nature Communications.
