Abstract Measurements of electrical conductivity, thermoelectric power, and crystallographic structure of tungsten trioxide are presented. It is found that the predominant charge carriers are electrons related to nonstoichiometry in the oxygen sublattice (WO 3− y ). At y = 0.1 the investigated material undergoes a sem…

Production scale separation of tritium from other hydrogen isotopes at the Savannah River Site (SRS) in Aiken, SC, USA, has been accomplished by several methods. These methods include thermal diffusion (1957–1986), fractional absorption (1964–1968), and cryogenic distillation (1967–present). Most recently, the Thermal…

The dynamics of the phase of the molecular tilt in the helical ferroelectric liquid crystalline Sm-${\mathit{C}}^{\mathrm{*}}$ phase is studied within the Landau model. We show that a static electric field applied parallel to smectic layers induces a gap in the excitation spectrum of the phase of the tilt at the edge…
