HYDROGEN bonds play a crucial role in the behaviour of water1–4; their spatial patterns and fluctuations characterize the structure and dynamics of the liquid5–7. The processes of breaking and making hydrogen bonds in the condensed phase can be probed indirectly by a variety of experimental tec...
Water is one of the most important, yet least understood, liquids in nature. Many anomalous properties of liquid water originate from its well-connected hydrogen bond network1, including unusually efficient vibrational energy redistribution and relaxation2. An accurate description of the ultrafast vibrati...

many excess H+ ionsare made adjacent to the exclusion zone of water. Gerald Pollack’s experiments have shown this exquisitely. The excess protons can then diffuse through the hydrogen bond network of water molecules or other hydrogen-bonded liquids (iodized CSF) through the formation or cleavage...
For CH4-H2O systems, increasing pressure induces a wettability transition from weakly water-wet to gas-wet due to the strong interaction between CH4 and the kerogen surfaces, which results in a smaller gas-solid interfacial tension compared with liquid-solid interfacial tension. Meanwhile, both the...

s hydrogen-bond network over distances of up to 2 nm. In the long wavelength limit these optical modes exhibit longitudinal–transverse splitting, indicating the presence of coherent long-range dipole–dipole interactions, as in ice. Our results indicate the dynamics of liquid water have more ...
The hydrogen bond networks make both the natural and sensitive materials to humidity levels in the atmosphere because water molecules can diffuse into the surface and disrupt the network. Some materials are more sensitive than others. Sign in to download full-size image Fig. 4-2. Para-aramid ...
