New Perspective: Bimolecular chemical reaction dynamics in liquids
Bimolecular reactions in the gas phase exhibit rich and varied dynamical behaviour, but whether a profound knowledge of the mechanisms of isolated reactive collisions can usefully inform our understanding of reactions in liquid solutions remains an open question. The fluctuating environment in a liquid may significantly alter the motions of the reacting particles and the flow of energy into the reaction products after a transition state has been crossed. Recent experimental and computational studies of exothermic reactions of CN radicals with organic molecules indicate that many features of the gas-phase dynamics are retained in solution. However, observed differences may also provide information on the ways in which a solvent modifies fundamental chemical mechanisms. This perspective examines progress in the use of time-resolved infra-red spectroscopy to study reaction dynamics in liquids, discusses how existing theories can guide the interpretation of experimental data, and suggests future challenges for this field of research.

New Perspective: Tipping the scales: Search for drifting constants from molecular spectra
In this Perspective, the authors review molecular species that are of specific interest in the search for a drifting proton-to-electron mass ratio μ. In particular, they outline the procedures that are used to calculate the sensitivity coefficients for transitions in these molecules and discuss current searches. These methods have led to a rate of change in μ bounded to 6 × 10−14/yr from a laboratory experiment performed in the present epoch. On a cosmological time scale, the variation is limited to |Δμ/μ| < 10−5 for look-back times of 10–12× 109 years and to |Δμ/μ| < 10−7 for look-back times of 7× 109 years. The last result, obtained from high-redshift observation of methanol, translates into μ ̇ /μ=(1.4±1.4)×10-17/yr if a linear rate of change is assumed. Read the Perspective.
New Perspective: Structural dynamics in condensed matter mapped by femtosecond x-ray diffraction
Ultrashort soft and hard x-ray pulses are sensitive probes of structural dynamics on the picometer length and femtosecond time scales of electronic and atomic motions. Recent progress in generating such pulses has initiated new directions of condensed matter research, exploiting a variety of x-ray absorption, scattering, and diffraction methods to probe photoinduced structural dynamics. Atomic motion, changes of local structure and long-range order, as well as correlated electron motion and charge transfer have been resolved in space and time, providing a most direct access to the physical mechanisms and interactions driving reversible and irreversible changes of structure. This perspective combines an overview of recent advances in femtosecond x-ray diffraction with a discussion on ongoing and future developments. Read the Perspective

New Perspective: Coulomb fluids - Weak coupling, strong coupling, in between and beyond
This Perspective presents a personal view on the current state of statistical mechanics of Coulomb fluids with special emphasis on the interactions between macromolecular surfaces, concentrating on the weak and the strong coupling limits. Both are introduced for a (primitive) counterion-only system in the presence of macroscopic, uniformly charged boundaries, where they can be derived systematically. Later it is shown how this formalism can be generalized to the cases with additional characteristic length scales that introduce new coupling parameters into the problem. Read the Perspective.
