Modelling NaCl concentration profiles across a cation exchange membrane in the transient regime

A model is developed to simulate NaCl concentrations across a cation exchange membrane in the transient regime. The convectionless Nersnt-Planck equation is combined with the continuity equation to obtain a partial dierential equation in time and space. The boundary conditions at the edges of the cell for this equationare a constant bulk...

Investigation of deposition-pressure-dependent photochromism, band gap tuning and photodarkening model for yttrium oxyhydride thin films

Photochromic smart windows form a promising class of energy-saving technologies for the built environment. In recent years, sputter-deposited yttrium oxyhydride (YO<i>_x</i>H<i>_y</i>) coatings have been gaining attention due to their desirable photochromic properties such as colour-neutral darkening, high contrast, and...
