2016/5/20
The fluorescence intensity from randomly oriented Rhodobacter ( Rb.) sphaeroides photosynthetic reaction centers at 77 K increases in an applied electric field. This is ascribed to a net reduction in ...
Electric field inside a "Rossky cavity" in uniformly polarized water
Cavity field, surface polarization, hydration, polar response.
2011/9/29
Electric field produced inside a solute by a uniformly polarized liquid is strongly affected by dipolar polarization of the liquid at the interface. We show, by numerical simulations, that the electri...
