Sample properties.

Property	Symbol	Value	Unit
Permeability^a	𝑘0	2.1⋅10^−10	[m^2]
Shape factor^b	𝑚	1.75	[—]
Porosity^c	𝜙	0.093	[—]
Tortuosity^d	𝛼∞	1.8	[—]
Debye length^e	𝑑	2.9⋅10^−8	[m]
Weighted pore volume-to-surface ratio^f	Λ	1.3⋅10^−4	[m]

^aThe permeability is measured directly. ^{b, d}The shape factor and the tortuosity are derived from an independent dynamic head experiment [27, 69], by means of curve fitting. ^cThe porosity is computed from [70, 71]. ^{e, f}The Debye length and the characteristic pore size are computed from theory (see [29, 59], respectively).
