The Electrostatic Interaction of a Charged Particle with a Surface: The Effect of Surface Charge Rearrangement [PDF]

Journal of Colloid and Interface Science, 2001
In this paper we investigate the electric interaction between a charged particle and a surface in which the charged ions are capable of moving in response to the electric potential disturbance caused by the approach of the charged particle. Such surfaces include ionic surfactants distributed in air-water interface and charged lipids in bilayer ...

Older People’s Attitudes to Road Charging: Are They Distinctive and What are the Implications for Policy? [PDF]

, 2011
In an ageing society older people have a growing influence on politics in general, and potentially on the acceptability of road charging in particular. They face specific types of risk of transport-related social exclusion which may influence their views
