A mean field model near the NAC point in liquid crystals
(Physical Soc Republic China, 2002-10)
In this study we obtain the phase line equations for the nematic-smectic A (NA), smectic A-smectic C (AC) and nematic-smectic C (NC) transitions using a mean field model. We fit these phase line equations to the experimental ...
Comparision of critical parameters of polymerization and gelation processes: A fast transient fluorescence study
(World Scientific Publ Co Pte Ltd, 2005-03-10)
The fast transient fluorescence technique was used to study free-radical polymerization and crosslinking copolymerization of styrene. Ethylene glycol dimethacrylate and Pyrene were used as crosslinking agent and fluorescence ...
Studying on the small molecule diffusion into hydrogels: a fluorescence study
(Amer Inst Physics, 2007)
In situ steady state fluorescence experiments (SSF) were reported during the diffusion of water molecules into PAAm in gels at various temperatures. The fluorescence emission intensities, Ip increased continuously as water ...
Strategies for the evolution of sex
(American Institute of Physics Inc., 2001-12)
The maintenance of a macroscopic sexual population is addressed. As a scenario, the mechanism of random conversion to sex, in the presence of a constant rate of mutation is examined. This scenario is very closely related ...
Fluctuation theory of the liquid-glass transition
(Trans Tech Publications Ltd, 2004)
The glassy state and the character of the liquid-glass transition from undercooled liquid to amorphous solid is one of the biggest challenges of our time. In spite of significant progress we still cannot explain accurately ...
