TLDR
Results serve to elucidate at the molecular level the course of change of a system to be followed from the gas to the condensed state, thereby enabling a spanning of the states of matter.Abstract:
Gas-phase clusters, which are weakly bound aggregates comprised of either atoms or molecules, often display properties that lie between those of the gaseous and condensed states. Interesting questions arise concerning how large a cluster must be before it will display bulk properties. Currently there is extensive research activity directed toward studies of their formation and varying properties and reactivity as a function of the degree of aggregation. Results serve to elucidate at the molecular level the course of change of a system to be followed from the gas to the condensed state, thereby enabling a spanning of the states of matter.read more

Nuclear fusion from explosions of femtosecond laser-heated deuterium clusters
TL;DR: In this paper, the authors reported the observation of nuclear fusion from the explosions of deuterium clusters heated with a compact, high-repetition-rate table-top laser, achieving an efficiency of about 105 fusion neutrons per joule of incident laser energy.

TL;DR: The field of cluster research can trace its origins back to the mid-nineteenth century when early studies of colloids, aerosols, and nucleation phenomena were reported.

High-energy ions produced in explosions of superheated atomic clusters

TL;DR: In the case of laser-heated xenon clusters, it was shown that the explosion of these superheated clusters ejects ions with substantial kinetic energy up to 1 MeV, four orders of magnitude higher than that achieved in the Coulomb explosion of small molecules as discussed by the authors.

Nanosurface Chemistry on Size-Selected Silicon Clusters
TL;DR: In this paper, the chemistry that occurs on the nanosurfaces of size-selected silicon clusters reveal a number of fascinating qualitative similarities to the behavior of bulk surfaces, and they suggest that these large silicon clusters are not just small crystals of bulk silicon, but have much more compact geometric structures.

Explosion of atomic clusters heated by high-intensity femtosecond laser pulses
Todd Ditmire,Emma Springate,John W. G. Tisch,Y. L. Shao,M. B. Mason,N. Hay,J. P. Marangos,M. H. R. Hutchinson +7 more
TL;DR: In this article, the physics governing the laser cluster interaction is fundamentally different than in previous studies, and there has been much activity in extending these studies to very high intensity, ultrashort laser pulses with peak laser intensities >1015 Wcm −2 and pulse widths of 0.1 to 10 ps.

Molecular dynamics study of melting and freezing of small Lennard-Jones clusters
TL;DR: In this paper, the properties of small clusters of Lennard-Jones atoms were studied by using molecular dynamics simulations, and it was found that these clusters undergo a transition, analogous to a melting transition for bulk materials, from a low-energy solidlike structure at low temperatures to a set of higher energy liquidlike structures at high temperatures.

Molecular Reaction Dynamics and Chemical Reactivity
TL;DR: In this article, the authors deal with the molecular-level mechanism of elementary chemical reactions, and progress from the basic principles of physical chemistry to up-to-date research results to provide an understanding of chemical reactivity and physical rate processes from the fundamental point of view of atom-atom interactions all the way to the description of catalysis.
