Ion oxide silicon capacitor based pH sensing
… As the name suggests, the device consists of an ionic layer on top of an oxidized Si wafer. The strength of the ionic solution determines the capacitance of the device, as the ionic strength modifies the work function of the ionic layer, thereby changing the surface potential of the device. The …

Preparation and Water-Gas Shift Performance of Zinc Oxide Supported Dispersed Gold Catalysts
… -where the support is added to a pH adjusted solution of HAuCI4 and the system aged at constant pH and temperature - was examined, using ZnO as the support. Gold uptake by the support was confirmed to decrease with ageing pH, tending to zero as the IEPS of ZnO (- 9) is approached. Such …

Study of Biological Ion Channels by Using PNP/ECP Model
… between the electrochemical potential of a real ionic solution and that of an idealized solution. The ECP terms are added to the electrostatic potential in the flux equations, yielding a modified set of PNP equations.

Fluid Characterisation Using Microfluidic Impedance Spectroscopy for Remote Health Monitoring
… such devices can be used to characterise aqueous ionic solutions by using impedance spectroscopy to directly measure their electrical properties. Impedance spectroscopy is a very well-established technique for the characterisation of solids but is less commonly used for liquids. Here the …
