Physics 2, 96 (2009) – Published November 16, 2009 Statistical Mechanics Soft Matter Directed percolation, a class of nonequilibrium phase transitions as prominent as the Ising model in equilibrium statistical mechanics, is realized experimentally for the first time, after more than fifty years of research. |

Physics 2, 67 (2009) – Published August 10, 2009 Atomic & Molecular Physics Statistical Mechanics Soft Matter Experiments on melting of small water clusters open the door to the study of the size-dependent phase diagram of water. |

Published June 29, 2009 The rapid evaporation of solvent during spin casting—a technique widely used in the manufacture of plastic parts—may prevent polymer films from reaching equilibrium. |

Published April 13, 2009 Scaling laws are a useful way to characterize fluid flow over a wide range of flow rates and experimental conditions. Theorists now explain several earlier experiments by finding a scaling law that describes how a liquid-liquid interface changes shape when driven by viscous forces. |

Published February 23, 2009 Gold wire networks made with a simple tabletop method may provide an alternative to more expensive transparent conductors. |

Synopsis
|
Published September 29, 2008 High-intensity x-ray measurements show how suspended particles in a narrow channel are attracted to—or repelled from—the channel walls depending on the ionic concentration of the suspension. These results could have implications for the design of nanofluidic devices. |

Physics 1, 22 (2008) – Published September 22, 2008 A shear force can melt a colloidal glass, causing it to flow in a highly nonlinear fashion. Physicists have now found a way to put the description of this type of flow on a more formal theoretical footing. |
