A new technique gives more detailed images of molecules by measuring the quantum mechanical repulsion between the imaged molecule and a small probe molecule.

The effects of ionizing radiation in an aqueous environment are often calculated in clusters of water molecules, but how well does this approximate the response of a bulk liquid?

Simulations reveal how laser-excited persistent currents in ring-shaped aromatic molecules couple to vibrational modes.

Experiments now quantitatively confirm the standard model of electrokinetics, in which electric fields drive the flow of electrolytes, potentially leading to better sensors and biomedical diagnostic devices.

New experiments extend chemical dynamics research to temperatures below $1$ microkelvin.

A combination of simulations and experiments explicitly demonstrates that common chemical reactions can drive convection flows in fluids.

Negative ions dissolved in water may be attracted to the surface because of the rearrangement of charges within the ions.

A new tool is developed to study dynamics of molecular dissociation under electron bombardment.

We can generally understand the way simple chemical combinations arise by assuming a standard valence structure for the elements, but a high-pressure study suggests that the rules for hydrogen may not be so easily pinned down.

Different molecules with nearly identical absorption spectra can be distinguished with the help of shaped laser pulses and adaptive algorithms.

The 2007 Nobel Prize in Chemistry went to a pioneer in surface science who explained several common reactions, including one that helps cars run cleaner.

Water molecules become frozen in place in a shell surrounding dissolved oily molecules, an important effect for proteins and other biomolecules.

New calculations explain why water has such a strong response to electric fields.

A nanoscale “thread” of water molecules could be a valuable tool for studying the behavior of water at the molecular level.

In a newly discovered phase of ice, the hydrogen nuclei appear to move and carry electric current–possibly powering planetary magnetic fields.

Researchers produced the fastest movies ever made of electron motion by shining x rays at water.

A computer simulation gives the structures of possible salt crystals at their moments of formation in salt water.

Water and all other liquids that expand as they cool can exist in two distinct forms, theorists say.

A new study reveals the structure of water bound to a metal surface, a fundamental yet long unanswered question.

Polarized light can determine the precise structure of a growing crystal, opening the way for fine-tuned pharmaceuticals and novel materials.
