Photoinduced molecular transport in biological environments based on dipole moment fluctuations

Article Abstract:

A study presented the possibility of a molecule moving unidirectionally in an electric field of a polar periodic substrate as a result of the fluctuations of molecular dipole moment occurring on the photoexcitation of the molecule. As estimated for such motion, molecules with sufficiently long fluorescence and strongly differing dipole moments in the ground and excited states could move with an average velocity of the same order as that typical of protein motors such as kinesin.

Nonlinear alternating current responses of electrorheological solids

Article Abstract:

The Ewald-Kornfield formulation is used to derive the local electric fields and induced dipole moments in a rigorous manner, so as to take into account the lattice effect on the nonlinear ac responses of electrorheological (ER) solids under structure transformation. Thus, by measuring the nonlinear ac responses of ER solids, it seems possible to perform a real time monitoring of structure transformation.

Asymmetric response in a line of optically driven metallic nanospheres

Article Abstract:

The dipole-dipole interactions between a linear array of optically driven silver metallic nanospheres (MNSs) are described. The model calculations incorporate the full electric field generated by an oscillating dipole and predict several interesting effects due to the retardation of the field.
