Recent developments based on relativistic hydrodynamic models in high energy heavy ion collisions are discussed. I focus especially on how hydrodynamics works at RHIC energies and how one can use the most of it in analyses of jet quenching and thermal electromagnetic radiations. I also comment on improvement of initial conditions and viscosity in hydrodynamic models.

The effect of cooling process for the synthesis and the superconductivity properties of Pb-substituted Bi-based materials, has been investigated. The preparation condition for the formation of (2,2,2,3) phase has been examined. The influence of thermal condition of the synthesis and quenching on the critical temperature and the content of 110K phase was investigated. Results of the ac-susceptib...

The competition between exciton dissociation and charge transport in organic solar cells comprising poly(3-hexylthiophene) [P3HT] and phenyl-C61-butyric acid methyl ester [PCBM] is investigated by correlated scanning confocal photoluminescence and photocurrent microscopies. Contrary to the general expectation that higher photoluminescence quenching is indicative of higher photocurrent, microsca...

Negative thermal quenching of both the excitonic and green emissions is observed in ZnO nanosheets, from which the energy level of surface traps can be extracted based on a model of multi-level transitions. The present study demonstrates a non-destructive and easy method to determine the trap levels in semiconductor nanostructures.

This work presents positive experimental evidence for the hole traps in ZnO nanorods, which take part in recombination and change the thermal quenching of Cu-related green emission. The evolution of Cu impurity upon annealing, as well as the formation of Cu-related shallow donors with an energy level of ∼0.11 eV are also indicated by temperature-dependent photoluminescence.

The AdS/CFT correspondence and a classical test string approximation are used to calculate the drag force on an external quark moving in a thermal plasma of N = 4 superYang-Mills theory. This computation is motivated by the phenomenon of jet-quenching in relativistic heavy ion collisions.
