Bulk approaches to studying heterogeneous systems obscure important details, as they report average behavior rather than the distribution of behaviors in such environments. Small-molecule and polymeric supercooled liquids, which display heterogeneity in their dynamics without an underlying structural heterogeneity that sets those dynamics, are important constituents of this category of condense...

In-plane frost growth on chilled hydrophobic surfaces is an inter-droplet phenomenon, where frozen droplets harvest water from neighboring supercooled liquid droplets to grow ice bridges that propagate across the surface in a chain reaction. To date, no surface has been able to passively prevent the in-plane growth of ice bridges across the population of supercooled condensate. Here, we demonst...

In part I it was demonstrated that supercooled liquid-water clouds can occur in the form of thin but radiatively signiŽ cant layers that are distinctive in lidar imagery due to their high backscatter coefŽ cient. In this paper, 18 months of near-continuous lidar data from two midlatitude locations are analysed to estimate the frequency of occurrence of such clouds as a function of temperature. ...

Confocal microscopy was used to directly observe three-dimensional dynamics of particles in colloidal supercooled fluids and colloidal glasses. The fastest particles moved cooperatively; connected clusters of these mobile particles could be identified; and the cluster size distribution, structure, and dynamics were investigated. The characteristic cluster size grew markedly in the supercooled f...

We review the available experimental information on the thermodynamic properties of supercooled water and demonstrate the possibility of modeling these thermodynamic properties on a theoretical basis. We show that by assuming the existence of a liquid-liquid critical point in supercooled water, the theory of critical phenomena can give an accurate account of the experimental thermodynamic-prope...

Under subzero degree conditions, free water contained in biological cells tends to freeze and then most living things die due to low temperatures. We examined the effect of a variable magnetic field on Drosophila under supercooled conditions (a state in which freezing is not caused even below the freezing point). Under such supercooled conditions with the magnetic field at 0°C for 72 hours, -4°...

Supercooled hydrogen liquid as well as superfluid have continued to elude experimental observation due to rapid crystallization. We computationally realized and investigated supercooled hydrogen liquid by a recently developed non-empirical real-time molecular dynamics method, which describes non-spherical hydrogen molecules with the nuclear quantum effects. We demonstrated that the hydrogen sup...

We investigate numerically chiral symmetry restoration at finite temperature in the planar limit in the deconfined phase, both when it is stable and when the system is supercooled. We find chiral symmetry restoration at Tχ = Td, where Td is the temperature of the deconfinement transition in pure gauge theory and Tχ < Td in the supercooled deconfined phase. In the stable case the spectrum of the...

Ž . Ž X Supercooled drizzle freezing drizzle was observed at Inuvik, N.W.T., Canada 68822 N, X . 133842 W on December 20, 21 and 27, 1995. Meteorological conditions in which the supercooled Ž . drizzle could form under low temperatures colder than y208C in the mid-winter season of the Canadian Arctic were examined from the sounding data and data measured by a passive Ž . microwave radiometer at...
