摘要:Direct visualization of concerted proton tunnelling in a water nanoclusterextrusiondie swellviscoelasticitymedial axisspectral elementsProton transfer through hydrogen bonds plays a fundamental role in many physical, chemical and biological processes. Proton dynamics is susceptible to quantum tunnelling, which typically involves many hydrogen bonds simultaneously, leading to correlated many...
