As pointed out in the discussion section, the general analysis outlined herein applies to far more general circumstances than those of microparticles into which water tunnels via straight, regularly shaped ‘free molecular volume’ cylindrical pores.

In effect, eqs 41–44 are an explicit method for inverting a triangular matrix.

This method of measurement is obviously approximate. Distinct mesopores become apparent by visual inspection of electron microscopic photos8 when mesopores reach a radius of approximately RM ≃ 1 μm. Measuring the rate of growth of pores in the domain RM ≥ 1 μm may or may not be equivalent to measuring the rate constant kcoal
