Abstract

Different growth modes of isolated cholesteric fingers of the second species (CF‐2) in an electric field at voltages near a coexistence line (V~2~) between cholesteric and nematic mesophases are in detail described. Videomicroscopy and computer image analysis were used for investigation of the pattern in polarized light. It is shown how a drift, a lengthening and a shape of fingers depend on the voltage at which the growth sets in and three typical scenarios are distinguished. (© 2009 WILEY‐VCH Verlag GmbH & Co.

Electrophoresis is one of the electrokinetic phenomena most widely investigated, both from a fundamental point of view and as a research tool in academia and industry. However, the dependence between electrophoretic mobility and zeta potential is, in a general case, far from simple, because of the m

## Abstract A positive change Δλ/λ of the decay constant of ^99^Tc^m^ has been observed on the application of an external electric field in K~2~TcX~6~ (X = F, Cl, Br, I). For its investigation the Tc‐complexes were embedded as small conglomerates or more or less as isolated single molecules in a po
