Differential thermal analysis and nuclear magnetic resonance spectroscopy experiments on whole flower buds and excised floral primordia of azalea (Rhododendron kosterianum, Schneid.) proved that supercooling is the mode of freezing resistance (avoidance) of azalea flower primordia. Increase in the linewidth of nuclear magnetic resonance spectra for water upon thawing supports the view that inju...

We observed asymmetric critical slowing down and dynamical scaling exponent in the superheating supercooling kinetic processes during thermally-induced metal-insulator transition of MnNiSn based Heusler alloy. During to insulator phase, critical-like features get enhanced compared back metal phase. These experimental findings suggest that metastable phase cooling branch hysteresis has approache...

We investigated the overwintering biology of four temperate-latitude bark beetles: Dendroctonus frontalis Zimmermann, Ips pini (Say), I. grandicollis (Eichhoff), and I. perroti Swaine. All four species were freeze-susceptible. However, there was variation within and among species in overwintering biology that related to their geographic distribution. D. frontalis and southern populations of I. ...

Isolates of 'Pseudomonas borealis' were recovered after ice-affinity selection of summer-collected soils. 'P. borealis' DL7 was further characterized and shown to have ice nucleation activity (INA), a property that allows the crystallization of ice at temperatures close to the melting point, effectively preventing the supercooling of water. INA was optimally detected after culturing at temperat...

Abstract Multicrystalline Mg 2 Si crystal with a diameter of 15 mm was grown via vertical Bridgman method. To clarify the growth mechanism multicrystalline structure, grain behavior analyzed. This carried out through segmenting grains by mean shift clustering using light intensity profile obtained from multiple optical reflection images wafers and stacking segmented direction. Further orientati...

We formulate and study a mechanical instability criterion for sudden hadronization of dense matter fireballs formed in 158A GeV Pb-Pb collisions. Considering properties of quark-gluon matter and hadron gas we obtain the phase boundary between these two phases and demonstrate that the required deep quark-gluon-plasma supercooling prior to sudden hadronization has occurred.

The sequence of phase transitions during the hot history of the universe is followed within a phenomenological framework. Particular emphasis is put on the QCD confinement transition, which is at reach under earth laboratory conditions. A tepid inflationary scenario on the GUT scale with bubble growth at moderate supercooling is discussed.
