WebThis leads to a potential application of quantum information processing and quantum storage in the encoded nonreciprocal spin diffusion, where its diffusion speed depends on the initial coherence between the excited atoms and is robust to their relative phase fluctuations. The state-dependent photon routing can be viable as well in this interface. WebA surface oxygen content (SOC)-dependent antibacterial mechanism and interaction mode of graphene materials are demonstrated. Graphene materials with high surface oxygen content predominantly attach in parallel to the bacterial cell surface. The interaction mode shifts to a perpendicular interaction when the SOC reaches a threshold. View the article.
