Effect of thermodynamic history on secondary relaxation in the glassy state
We investigated by dielectric spectroscopy the effect that the thermodynamic history of a glass has on the secondary relaxation process. In particular we focused our attention to glassy states at the same conditions of ...
Modeling and Simulation of Hamburger Cooking Process Using Finite Difference and CFD Methods
Unsteady-state heat transfer in hamburger cooking process was modeled using one dimensional finite difference (FD) and three dimensional computational fluid dynamic (CFD) models. A double-sided cooking system was designed ...
Effect of temperature and pressure on the stractural (a-) and the true Johari-Goldstein (b-) relaxation in binary mixtures
We investigated the microscopic origin of the excess wing through isothermal and isobaric dielectric relaxation measurements for the Quinaldine/tristyrene mixture. Our results show that the excess wing, characteristic of ...
Secondary dynamics in glass formers: relation with the structural process and the glass transition
In this paper, we study secondary relaxations in a neat glass former close and below the glass transition. The pressure and temperature dependences of the characteristic relaxation frequencies were investigated to find a ...
