Researchers at Osaka Metropolitan University and Fraunhofer Institute for Mechanics of Materials IWM have discovered that certain chemical impurities can make carbon surfaces superslippery. This finding challenges the conventional approach of treating impurities as a problem to be eliminated in order to improve material performance. Instead, the study suggests that a controlled amount of chemical impurities can have a beneficial effect on the sliding properties of carbon surfaces. The research, published in Advanced Science, provides new insights into the relationship between material purity and performance, and may have implications for the development of advanced materials and technologies.
