Self-diffusion in liquid water
The Journal of Chemical Physics, 1977The behavior of the self-diffusion coefficient in water, along the coexistence curve for −31 °C⩽T⩽350 °C, is explained in terms of local fluctuations of free volume, energy per molecule, and ’’percentage of broken H bond’’ as derived from ir data. Our theoretical expression agrees with the experimental data, within their errors, in the overall range we

Physical Review E, 1993
Both inelastic-neutron-scattering experiments and computer simulations have established that liquid water can support a longitudinal mode propagating with a velocity much larger than the ordinary speed of sound. The physics behind this peculiar behavior is studied by a comprehensive microscopic approach.

Multiple Phases of Liquid Water
ChemPhysChem, 2008AbstractThe history of the study of the anomalies of liquid water, from the 17th century up to the present, is reviewed and the current view on the origin of these anomalies is summarized. The hypothesis of the multiple liquid–liquid transitions of water in the supercooled region is consistent with the available experimental and simulation data and ...

Collective Dynamical Properties of Liquid Water
Physical Review Letters, 1988A theoretical and computer simulation analysis suggests that two collective modes can propagate in liquid water for wave vectors $kg0.64$ ${\mathrm{\AA{}}}^{\ensuremath{-}1}$. The low-frequency mode (ordinary sound) turns out to be associated with the oxygen density fluctuations, whereas the hydrogen density fluctuations are found to be governed by ...

Particle-phase liquid water is a ubiquitous and abundant component of atmospheric aerosols and influences hydrological cycling, fate and transport of trace species, visibility, human health, and regional climate. Aerosol water mass concentrations are functions of relative humidity (RH), temperature, and aerosol concentration and composition.

Photoresponsive Liquid Marbles and Dry Water
Langmuir, 2014Stimuli-responsive liquid marbles for controlled release typically rely on organic moieties that require lengthy syntheses. We report herein a facile, one-step synthesis of hydrophobic and oleophobic TiO2 nanoparticles that display photoresponsive wettability.

Science and society are failing to grapple with the public health burden of cancer. In this short perspective piece, I contrast reductionism and complexity in cancer research, using water as a simple example, arguing for more 'ecological' approaches to cancer. This is a call to arms to physical scientists, ecologists and others to get involved, to link

Correlated libration in liquid water
The Journal of Chemical PhysicsThe libration spectrum of liquid H2O is resolved into an octupolar twisting libration band at 485 cm−1 and dipolar rocking–wagging libration bands at 707 and 743 cm−1 using polarization analysis of the hyper-Raman scattering (HRS) spectrum. Dipole interactions and orientation correlation over distances less than 2 nm account for the 36 cm−1 splitting ...
