Investigation into the temperature dependence of isotropic- nematic phase transition of Gay- Berne liquid crystals
Density functional approach was used to study the isotropic- nematic (I-N) transition and calculate the values of freezing parameters of the Gay- Berne liquid crystal model. New direct and pair correlation functions of a molecular fluid with Gay- Berne pair potential were used. These new functions were used in density functional theory as input to calculate the isotropic- nematic transition den...
متن کاملHigh resolution Hall measurements across the VO2 metal-insulator transition reveal impact of spatial phase separation
Many strongly correlated transition metal oxides exhibit a metal-insulator transition (MIT), the manipulation of which is essential for their application as active device elements. However, such manipulation is hindered by lack of microscopic understanding of mechanisms involved in these transitions. A prototypical example is VO2, where previous studies indicated that the MIT resistance change ...
متن کاملa comparative pragmatic analysis of the speech act of “disagreement” across english and persian
the speech act of disagreement has been one of the speech acts that has received the least attention in the field of pragmatics. this study investigates the ways power relations, social distance, formality of the context, gender, and language proficiency (for efl learners) influence disagreement and politeness strategies. the participants of the study were 200 male and female native persian s...
15 صفحه اولMetal-insulator Phase Transition in Vo2
-The effects of doping and uniaxial stress on the structural and magnetic properties of V02 are reviewed. Important electron-electron correlation effects are deduced : (i) in the metallic phase from the results obtained in V I ~ N ~ ~ O ~ alloys, (ii) in the insulating phases of pure V02 at ambiant pressure (MI), under uniaxial stress or in the presence of Cr impurities (T and M2). Discovered i...
