Capacitive de-ionisation is emerging as a viable technology for water desalination. The technique based on electrochemical fundamentals: it rests the potential-dependent adsorption of ions within pores high surface area electrode materials. process normally capacitive, although Faradaic approaches have been reported recently. Most rapidly expanding literature this topic focusses material scienc...

I review observations of the X–ray spectra of Galactic Black Hole Candidates, and theoretical ideas as to how these can be produced. X–ray reflection should enable different source geometries to be distinguished, but the ionisation instability of X–ray irradiated material in hydrostatic equilibrium gives rise to large ambiguities in interpretation. It is not currently possible to determine whet...

-In this work the five-fold differential doubleionisation cross section of helium by the impact of fast charged particles has been investigated. The case is considered in which little momentum is transferred to the target so that a Born-type approximation in the projectile-target potential can be employed. A scaling formula for the cross section has been derived which relates cross sections res...

The gas-phase reactions of ozone with alkenes can be significant sources of free radicals (OH, HO2 and RO2) in the Earth’s atmosphere. In this study the total radical production and degradation products from ethene ozonolysis have been measured, under conditions relevant to the troposphere, during a series of detailed simulation chamber experiments. Experiments were carried out in the European ...
